It uses the system to heat the injection material and precise temperature control means to pass the molten plastic material through the precision The designed runner, the hot nozzle is directly delivered to the mold cavity, effectively reducing the pressure of the runner (so a smaller injection molding machine can be used to save costs), the fluidity of the melt is improved, the material density is uniform, and the internal stress of the product is reduced Small, make the product get smaller deformation, better product surface quality and mechanical properties, for transparent parts, thin parts, large parts or plastic parts with special requirements (such as engineering plastic parts) can show its superiority.　　4, provide more molding process parameters, which can accurately control product quality.　　 Compared with the traditional cold runner, it has the following advantages: 　　1, shorten the molding cycle, greatly improve the production efficiency.　　 In general, the use of hot runner system in the injection process can save 10%-20% of raw materials, reduce costs by about 30%, and increase investment by only 10%-30%.. Generally divided into two categories: open type and needle valve type. Therefore, the hot runner system has been widely used abroad, and it has also been used as one of the popularization technologies for future injection mold development in China.　　3, to ensure the dimensional accuracy of the hot runner and the matching tolerance with the mold to prevent leakage of glue. Another feature of the hot runner system is that the hot nozzle directly injects the molten plastic material into the mold cavity, which naturally forms an automatic glue break during the demolding process, eliminating all or most of the runner waste caused by the traditional injection process , No post-processing is required, and a lot of materials are saved.　　2, the runner is processing of plastic products highly smooth and has no dead ends, ensuring rapid color change, preventing material degradation and improving efficiency.　　Second, the role of hot runner: 　　The hot runner system is a new and scientific injection molding system. The air pressure or oil pressure that controls the valve needle movement is appropriate.　　The hot runner system is a precise and complex injection molding system. In addition to matching accuracy, the main factors that determine the quality of the hot runner system are many other key factors, as follows: 　　1, accurately control the plastic temperature to prevent material degradation.　　6, the choice of hot nozzle is scientific and reasonable to ensure the smooth flow of plastic and the full filling of the cavity. In addition, because the additional heat caused by waste is eliminated, the cooling time of the mold is only the cooling time of the plastic part, which shortens the molding cycle and improves the automation and production efficiency of production , More importantly, the saving of materials and energy is of greater significance to the protection of the environment. It is composed of three parts: hot nozzle, manifold and temperature controller. It directly reaches the mold cavity from the barrel nozzle by heating the plastic in the runner and keeping it in a molten state. If the pressure is too small, the valve needle will not move or move in place. The working principle of the hot runner system: 　　The hot runner system is mainly composed of a manifold, a hot nozzle and a temperature control box.　　6, the product has no nozzle material, which greatly reduces the production cost.　　5, through a special design, it can form small pitch multi-cavity products and low pressure injection molding.　　7.　　3, reduce the stress of plastic parts, reduce deformation, and greatly improve product consistency.1. If the pressure is too high, it is easy to damage the hot nozzle and the mold.

4, the valve needle closes and opens in time, flexible action to prevent drooling at the glue inlet.　　2, reduce the injection pressure and clamping force, greatly improving the life of the mold.　　8, using needle valve hot nozzle, step-by-step injection molding, it can form difficult precision plastic products.　　7, to improve the appearance of the product and greatly improve the quality of the product. 　　5, balanced and reasonable design of runners to ensure uniform and rapid filling of each cavity

Its specific characteristics are as follows: the heating temperature of the barrel is low. Due to the low melting temperature of the material, the shrinkage rate is reduced, and the shrinkage phenomenon is less. Because the resin melts at low temperature, the loss of the color of the pigment is small; when molding the filling material containing chemical foaming agent, the melting temperature and the foaming temperature can be associated with each other. Due to the structural reasons of some molds, cooling water cannot be passed through locally.https://www.ledwaterprooflighting.com/product/led-tri-proof-light/

　　5, low injection pressure, high screw speed. Next, I will introduce you to power melt injection molding. Due to the high-speed rotation of the screw, the molten material obtained by dynamic melting is uniform, and the injection pressure only needs to be 50% to 80% of the ordinary injection pressure. 2.　　The main advantage of power melt injection molding is \u0026quot;energy saving\u0026quot;. The heat of the molten material mainly depends on the mechanical shear heat, and the melting temperature of the material is low and the temperature difference is small.

Another development direction of heat treatment technology improvement is to combine traditional heat treatment technology with advanced surface treatment technology to increase the service life of die-casting molds. Loose defects also make the internal structure of the blank reach broken grains Plastic Injection Molded Automotive Parts in the forged state. Its basic process is as follows: first low-speed or high-speed casting of molten metal into the cavity of the mold, the mold has a movable cavity surface, it is pressurized forging with the cooling process of the molten metal, which eliminates the shrinkage of the blank. For example, the chemical heat treatment method carbonitriding, NQN (i.; 　　The traditional heat treatment process of die-casting mold is quenching-tempering, and later Developed surface treatment technology.Die casting mold is a method of casting liquid die forging, a process completed on a dedicated die casting die forging machine.　　 This type includes carburizing, nitriding, boronizing, carbonitriding, sulfur carbonitriding, etc. Due to the variety of materials that can be used as die-casting molds, the same surface treatment technology and process will produce different effects on different materials. carbonitriding-quenching-carbonitriding) composite strengthening combined with conventional quenching and tempering processes, not only obtains higher surface hardness, but also effectively hardens The layer depth increases, the hardness gradient distribution of the infiltrated layer is reasonable, the tempering stability and the corrosion resistance are improved, so that the die-casting mold has a good core performance, while the surface quality and performance are greatly improved. The carburizing process used in cold, hot work and surface strengthening of plastic molds can improve the life of the mold. Next, Shenzhen Plastic Mold Factory will explain to you, what are the common problems of die-casting molds and the treatment methods? 　　 (1) Coating technology, including electroless plating, etc.e. The comprehensive mechanical properties of the blank have been significantly improved. When carburizing, the main process methods include solid powder carburizing, gas carburizing, vacuum carburizing, ion carburizing, and carbonitriding formed by adding nitrogen to the carburizing atmosphere.. This technology has the characteristics of fast carburization, uniform carburization, smooth carbon concentration gradient, and small workpiece deformation. On the basis of traditional technology, it proposes suitable processing technology for different mold materials to improve mold performance and increase mold life. (2) Improvement technology of traditional heat treatment process; 　https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/


Surface modification technology, including surface thermal expansion treatment, surface phase change strengthening, electric spark strengthening technology, etc. Play an increasingly important role in surface treatment. Yutongda recently proposed substrate pretreatment technology for mold substrate and surface treatment technology. Among them, vacuum carburizing and ion carburizing are technologies developed in the past 20 years. It will be on the surface of the mold, especially the precision mold

According to the current process characteristics, the overall requirements of wood-plastic products for molds are: first of all, they can produce high-quality wood-plastic products that can meet the needs of use in terms of appearance, dimensional accuracy, and physical properties; the requirements from the perspective of mold use are: High production efficiency, automation, simple operation and easy maintenance; from the perspective of mold manufacturing, the requirements are: reasonable mold structure, easy production, low cost, and can be accepted by the majority of users.　　https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/

Therefore, extrusion molding is used in wood-plastic material processing. Extrusion mould: Floors, profiles, doors and windows, plates, sheets and other products are all formed by extrusion moulds. It has an important position in production. In the wood-plastic products and industrial wood-plastic applications that thin wall injection molding we see daily, wood-plastic molds can be divided into the following categories according to the production process of the products: 　　1, injection molding molds: seats in public venues, home appliances shells, and children’s toys. In modern industrial production, product molding is a more common method, and wood-plastic product manufacturing is no exception. Products molded by injection molds. Such products account for more than 60% of the current domestic wood-plastic products.　　

Press-forming molds: The products we are familiar with, such as automobile interior panels, ship partitions, and vehicle cockpit panels, are produced by pressing molds. As a new type of composite material, wood-plastic material is usually processed by blending natural plant fiber materials, such as straw, rice husk, wood flour, hemp fiber, and different polymer substrates.Wood plastic molds are used to make all kinds of wood plastic products

At the same time, higher requirements have been put forward for the comprehensive

mechanical properties and life of die-casting molds. With the continuous development and

improvement of rapid prototyping software and hardware equipment and rapid prototyping

materials, the strength and accuracy of rapid prototyping have been continuously improved,https://www.nbtianke.com/product/
and rapid prototyping Technology has gradually penetrated into the field of rapid mold

manufacturing, and the production of various simple and economical rapid molds based on

rapid prototyping methods has become a hot issue for RPu0026amp;M applications.. This is

because, with the rapid development of my country’s automobile and motorcycle industry, the

die-casting industry has ushered in a new era of development. On the other hand, many die-

casting mold companies in my country are also one of the main reasons.　　In the automobile

and home appliance manufacturing industries, mold forming parts account for 50% to 70% of

manufacturing man-hours. The current development of scientific skills in the die-casting

mold industry in my country is still relatively backward.According to media reports, in

recent years, my country’s die-casting enterprises have paid more and more attention to the

quality of die-casting parts and die-casting molds.　　It can be seen that if my country

wants to develop from a large die-casting country to a powerful die-casting country, it

must work hard on the quality of die-casting molds and increase the intensity of research

and development of large, sophisticated, and high-skilled medium and high-end die-casting

molds. On the one hand, it is because of the relatively abundant mineral resources in my

country.　　 my country is a well-known country with a large output of die-casting molds.

The production capacity of China’s die-casting mold industry has accounted for nearly

10% of the world’s total. Mold manufacturing is the bottleneck and key that restricts the

development of China’s automobile, home appliance, light industry and other industries.

Although it has squeezed out of the world’s frontier, the overall level of die-casting

molds is comparable to that of the prosperous countries such as Germany, the United States,

and Japan, and it is about Thin-wall injection molding 10 years behind. At the same time, the

overall level of die-casting molds in my country does not match the total annual output.

Only by vigorously developing scientific skills can we further promote the continuous

development ofThin-wall injection molding

Analysis of injection mold price parts includes all aspects of mold production and design. The part surface, barb, wall thickness, taper angle, surface roughness analysis, milling and shrinkage are analyzed, and virtual mold design can also be performed. Through these analysis, mold production personnel can understand the difficulties in the mold manufacturing and production process, and predict the problems that will occur in the follow-up work. The analysis result can be automatically inserted into the third step quotation, making the quotation more professional.　　https://www.nbtianke.com/product
The price of injection mold is persuasive to provide mold manufacturer quotation, so thePlastic quality Plastic Molded Automotive Parts cap mould/mold quotation of injection mold is reasonable. For mold manufacturing companies, it can make quotations more professional, increase the bid winning rate, and avoid risks in actual mold production. For valuation, the valuation process is very simple, because T provides a basic survey form. These forms involve the complexity of the geometry of the parts, the use of materials, the number of mold blocks and sliders used in mold manufacturing, the number of electrodes used and the complexity of mold processing, injection molding technology and process requirements. The user only needs to fill in these forms and provide the customer with a mold estimate. This is the automatic generation of citations. It provides a template customization function, and users can define professional and personalized quotation templates.　　
When the quotation form is automatically generated, these templates can be selected to generate quotations and quotations. Since the quotation document is a word document, the user can make further modifications according to the automatically generated quotation to meet the needs of the user. In order to ensure that the quotation of the software conforms to the actual production of the enterprise, the software should be adjusted to the software before the quotation. It’s like buying a new radio. If users want to listen to local radio channels, they must first tune the radio to a specific frequency band, and the purpose of tuning is also correct. When the system is installed, the parameters used in the evaluation mathematical model of the injection mold quotation are all default parameters. If these parameters are used directly, the quotation will naturally contradict the production practices of various companies. Tuning is also the process of establishing a database.　　

Users need to classify molds according to the size and complexity of the enterprise, and use software to create different processes, and then use different processes to reference the software of previous molds.

There is a gap between the price of the software and the company’s ideal quotation. The so-called ideal quotation is the true price of customer cost plus profit. If the history of a pair of mold quotes is a loss, a company needs to calculate the ideal quote. Tuning is to use a series of factors to make the price of the injection mold of the software meet the company’s ideal quotation.

With the continuous development of information technology, its technical content and complexity are getting higher and higher. The concept of intelligence has gradually penetrated into all walks of life and all aspects of our lives. Smart residential communities and smart hospitals have emerged one after another. With the development of intelligent buildings as the basis, intelligentization is even more indispensable in the development of industrial industries.　　 https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/

With the rapid development of modern communication technology, computer network technology and fieldbus control technology, digitization, networking and information technology are increasingly integrated into people’s lives. Based on the continuous improvement and improvement of living standards and living conditions, people have put forward higher requirements for the quality of life. Smart precision mold manufacturing residential communities are produced under this background, and their demand is increasing, and the content of intelligence is also increasing. New concepts are constantly being incorporated. Smart molds were born under the promotion of modern science and technology. Smart molds are a necessary condition for the development of modern Chinese quality Injection mould manufacturing. Therefore, the demand for smart molds will increase with the development of the industry. The market determines production, and smart molds are the needs of the future.

Most, of course, will become the development direction of the mold industry. The rapid development of China’s mold industry must develop smart molds. It is reported that with the unsustainable low-cost human resources and the continuous development of science and technology in China, automation and intelligent manufacturing will inevitably become an important development direction of modern manufacturing. Mould will also develop rapidly. Using smart molds to produce products can further improve product quality and production efficiency, save materials, and realize automated production and green manufacturing.

Therefore, although the total amount of smart molds is not large at present, it represents the new development direction of mold technology and will play an increasingly important role in the adjustment of industry product structure and the transformation of development methods. The development of smart molds will inevitably promote the rapid improvement of the entire mold industry. Therefore, it is especially necessary to give priority to the development of smart molds in the development of the industry.　　

The development of smart molds is not only a new requirement of the manufacturing industry for the mold industry, but it is also a driving force for the further development of the mold industry. Therefore, it will definitely become the development direction of the mold industry in the future.

The requirements of modern industry for injection molded parts not only require high precision, but also have excellent internal quality. To meet this Plastic Injection Molded Automotive Parts requirement, new injection mold technology must be developed and utilized. At present, injection molds imported from abroad are being gradually promoted in the southern coastal areas. The new technology has played a big role in improving the quality of injection molded parts. In the past few decades, the domestic plastic mold industry has developed rapidly, and the thirst and requirements for talents have become higher and higher. However, the domestic still cannot solve this thorny problem, which has become a major obstacle to the development of China’s mold industry.　https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/　
It is understood that the mold production areas in coastal areas are unable to recruit people to varying degrees. In order to attract talents, many local mold companies even recruit across regions and provinces. Three kinds of talents make up the mold industry. ’Golden collar’ personnel are proficient in mold design software and mold structure knowledge, and have accumulated a lot of practical experience in actual work. This kind of person is very suitable to serve as the technical leader or technical director of each enterprise. ’Gray-collar’ refers to the personnel who design and process molds on their posts. Such personnel account for 15% of the company’s mold technology positions. ’Blue-collar’ refers to the technical staff responsible for the specific operation and daily maintenance of the mold in the production position, accounting for 75% of the corporate positions, which is currently the most in demand. This has become one of the major obstacles to the domestic mold industry. Strengthening the training of professional talents is an urgent matter for the mold industry. 　　
With the rapid development of the injection mold industry, a new model of injection mold manufacturing based on the information age. The production efficiency of the injection mold industry has been greatly improved, and the impact on the manufacturing industry has a milestone impact. Because of the organic combination of product information and manufacturing information related to injection mold manufacturing activities, traditional manufacturing has developed rapidly. In the information age, this advantage has been extremely well played and embodied. The modern manufacturing process can be regarded as the value-added process of the amount of information contained in raw materials, and the drive of industrial information flow will become the mainstream of the manufacturing industry.　　 Because injection molded products are widely used in daily life, mold technology has become an important indicator of a country’s product manufacturing level.　　 In recent years, my country’s injection molds have developed rapidly in terms of quality and quantity. However, compared with foreign advanced technologies, the technical standards of most Chinese enterprises still need to be improved. At present, compared with the advanced technology level of foreign countries, China’s injection mold industry has the following problems: The contradiction between supply and demand is difficult to solve in the short term: domestic injection mold domestic market satisfaction rate has been less than 74%, of which the satisfaction rate of large, precise and long-life molds is lower. .
At present, the transfer of molds from industrially developed countries to China is accelerating, and international purchases are increasing. The market demand is strong, production development is still difficult to keep up for a while, and the situation of short supply will continue for some time. Unbalanced industrial development: Although the products of individual companies have reached or are close to the international advanced level, overall, the accuracy, production cycle, and service life of molds are still far behind foreign countries. The overall level of industrial development is relatively low. low.

Therefore, previously the task that consumed up a few days&plastic clothes clips39; time, can now be done within a few hours.
