Precision Injection Molding Machine Replaces Conventional Injection Molding Machine The precision injection molding machine is an injection machine with closed-loop control of injection molding. Usually, the injection pressure and injection speed of the injection molding machine are controlled by closed loop. The so-called closed-loop control is also called feedback control. It refers to detecting the…
DetailsPrecision Molding Process The precision molding process is mainly a process method realized on a precision injection molding machine, mainly adopting multi-stage injection molding and precisely controlling the mold temperature. Multi-stage injection molding refers to the control of process parameters such as different injection speeds and different injection pressures at different positions when the screw…

DetailsTungsten Argon Arc Welding 1. Scope of application Tungsten argon arc welding can weld almost all metals and alloys, but due to the high production cost, it is generally only used for welding stainless steel, heat-resistant steel and non-ferrous metals such as copper, titanium, aluminum and magnesium. For metals with low melting point (low boiling…
DetailsIndirect Mold Casting Method (1) Ceramic type precision casting method This method can be used when producing steel molds in a single piece or in small batches. The process is: RP prototype as the master mold → dipping ceramic mortar → curing the mold shell in the oven → burning the master mold → preheating…
