injection China Terminal Blocks Manufacturers machine has three types of screws to choose from, namely, standard screw, low pressure injection screw, and HiMelt screw, so it can be applied to different materials, especially suitable for processing those with 25% added ～30% glass fiber reinforced plastic materials, such as LCP, PBT, PPA, PA6, PPS, PA 66, PPO, PC, PEI, etc. The melting temperature of PPA, PPS, PPO, PEI and other materials is very high and corrosive It is very strong and wears a lot of screws. Hi-Melt screws are specially prepared for the production of these materials. The mold is also one of the key factors for the successful injection of thin-walled parts. Generally, in order to prevent the gate from solidifying, the molten thermoplastic material must be quickly injected into the mold cavity by means of high pressure.
The thinner the wall thickness of the part, the higher the injection pressure and the shorter the molding cycle. For example, if a standard part is filled within 2s, its thickness will be reduced by 25%. For the above reasons, recommends that the selected mold must have good rigidity to ensure that it does not deform during high-speed injection. At the same time, a hot runner system should be used to minimize pressure loss during the injection molding process.
Of course, it is also necessary to use a vacuum system in the mold, which helps to achieve good exhaust during high-speed injection molding. SIEMENS with insert connector production site SynErgy injection molding machine is used for the production of electronic and electrical components.
In addition to the high-pressure injection unit, customers can also choose to use the standard injection unit, which makes it easy for customers to use The same machine produces other plastic products. When the weight of the produced product increases, only a larger screw needs to be appropriately replaced. Usually, replacing the screw and debugging the machine can be completed in a very short time.
