What are the main factors affecting the mold? Why mold temperature control of mold temperature machine is important for high gloss injection

The key to the high-gloss injection mold temperature machine is the mold temperature control system. Because the biggest difference between high-gloss injection molding and general injection molding is the control of mold temperature, and the requirements for injection molding machines are not high. The high-gloss injection mold temperature control system is also generally called the high-gloss mold temperature machine. It cooperates with the general injection molding machine to coordinate actions during the filling, holding, cooling, and opening and closing of the mold during injection molding. In the entire high-gloss seamless injection molding process, the quality of the mold design is one of the important factors that directly affects the quality of the product. The quality of the mold also directly leads to the appearance quality and product cycle of the product. The main factors affecting molds are mold materials, mold design and manufacturing processing:

New mold technology, the development and application of new mold technology is the direction of future development
New mold technology, R & D and application of new mold technology is the direction of future development. It is understood that the development and application of new mold technology will become the key development direction of domestic mold manufacturing in the future. The high-end route of China’s automotive mold is the only way for mold companies to develop. The market demand and development also promotes the large-scale multi-station progressive die supporting other large and medium-sized stamping parts. It is understood that the research and development and application of new mold technology will become the key development direction of domestic mold manufacturing in the future. The high-end route of China’s automotive mold is the only way for mold companies to develop, the city …

First, the mold material The mold material needs to have good polishability, corrosion resistance, wear resistance, thermal strength, toughness, processing performance, and low thermal expansion coefficient. Among them, polishability, corrosion resistance, thermal strength, and thermal expansion coefficient are particularly important for high-gloss molds. If the mold is poorly polished, the surface roughness is large, or it is corroded or there is water deposition during injection molding, high gloss product molding cannot be performed; rapid changes in temperature have higher requirements on the thermal strength and thermal expansion coefficient of the mold material. High-gloss mold materials include Hitachi Metal CENA1, Japan Datong NAK80 and S-STAR, ASSAB 5136 or S136H (420), POLMAX and other mirror surfaces, high wear-resistant, corrosion-resistant mold steel, and low-grade high-gloss molds also use conventional mold materials such as P20. CENAlα, a material for ultra-large plastic molds developed by Hitachi Metals, is a product specially developed for high-gloss molds and won the 2007 New Product Award in Japan. It has good comprehensive performance, good wear resistance, workability, toughness, and corrosion resistance, and excellent polishability. It is one of the best mold materials for high-gloss mirror molding.

Second, mold design and manufacturing In addition to the high surface quality requirements of the mold, the dynamic change of the mold temperature leads to a structure that is much more complicated than the ordinary mold. The design and manufacture of the internal pipeline of the mold is the key to affecting the mold quality, production cycle and mold cost. .

Third, in terms of high-gloss molds, there are currently problems such as single mold materials, high prices, high mold manufacturing costs, low mold life, complex mold manufacturing difficulties, and long cycles. Therefore, high-gloss injection is limited to products with simple molding structures such as flat plastic shells Appearance products with simple structure such as body. In the future, it is necessary to research and develop new high-gloss precision mold manufacturing technologies and new mold materials, combined with modern CAE technology, rapid manufacturing technology, polishing process, surface processing technology, etc., to achieve efficient and precise design and processing of the mold surface, mold internal piping, and mold parts.

The overall design of the mold, the overall design and manufacturing technology of the large composite wind turbine blade mold
The overall design of the mold, the overall design and manufacturing technology of the large-scale composite material wind power blade mold The composite material wind power blade is a key component of the energy conversion in the wind turbine, and its design and manufacture are directly related to the efficiency and service life of the wind turbine, which affects The performance of the entire system. The quality of the blade molding depends on the quality of the mold. High-precision mold design and manufacturing technology is an important guarantee for the aerodynamic shape of the blade and plays a decisive role in the production efficiency, final quality and performance of the product. As wind turbines continue to develop in the direction of large-scale, the size of wind turbine blades gradually increases …
