What factors affect the quality of the injection mould?
What are the main factors affecting the mold? Why the mold temperature control of the mold temperature machine is important for high-gloss injection molding
The most critical of 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 the mold temperature, the requirements for the injection molding machine are not high. The high-gloss injection mold temperature control system is also commonly called the high-gloss mold temperature machine. It cooperates with a general-purpose injection molding machine to coordinate actions during the filling, holding, cooling, and opening and closing of the injection mold. Throughout the high-gloss non-marking injection molding process, the quality of the mold design is one of the important factors that directly affect the quality of the product. The quality of the mold also directly leads to the key to product appearance quality and product cycle. The main factors affecting the mold are mold material, mold design and manufacturing:
New mold technology, R & D and application of new mold technology is the future development direction
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 definitely become the key development direction of the domestic mold manufacturing industry in the future. The high-end route of China's automotive molds is the only way for mold companies to develop. The market demand and development have also prompted other large and medium-sized progressive die supporting large and medium-sized stamping parts to be developed. It is understood that the development and application of new mold technology will definitely become the key development direction of the domestic mold manufacturing industry in the future. The high-end route of China's automotive molds is the only way for mold companies to develop.
First, mold materials Mold materials need to have good polishing, corrosion resistance, wear resistance, thermal strength, toughness, processability, and low thermal expansion coefficient. Among them, polishing, 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 moisture deposition during injection molding, high-gloss products cannot be molded; rapid temperature changes have higher requirements for the thermal strength and coefficient of thermal expansion of the mold materials. Currently used High-gloss mold materials include Hitachi Metal CENA1, Japan's Datong NAK80 and S-STAR, ASSAB's 5136 or S136H (420), POLMAX and other mirror-surface, high wear-resistant, corrosion-resistant mold steel, and low-grade high-gloss molds also use P20 and other conventional mold materials. CENAlα, a material for ultra-large plastic molding molds developed by Hitachi Metals, is a product specially developed for high-gloss molds and won the 2007 Japan New Product Award. Its comprehensive properties are good, abrasion resistance, processability, toughness, and corrosion resistance are all good, and its polishing is very good, 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 changes in mold temperature cause the structure to be much more complicated than ordinary molds. The design and manufacture of the internal pipeline of the mold are the key factors that affect the mold quality, production cycle and mold cost. .
Third, in terms of high-gloss molds, currently there are problems such as single mold materials, high prices, high mold manufacturing costs, low mold life, difficult mold manufacturing, and long cycle times, making high-gloss injection molding limited to products with simple molding structures such as flat plastic shells. Appearance products with simple structure. In the future, it is necessary to research and develop new high-precision mold manufacturing technology and new mold materials, combined with modern CAE technology, rapid manufacturing technology, polishing technology, surface processing technology, etc., to achieve efficient and precise design and processing of mold surfaces, mold internal pipes, and mold parts.
