Precision plastic mold (Wenzhou precision plastic mold factory) classification system according to the gating system different type of precision plastic mold can be divided into three categories: (1) large outlet precision plastic mold: runner and gate at the parting line, and product ejection together during the open mode, design the most simple, easy processing, low cost, so the more people using a large intake system operations. Plastic mold structure is divided into two parts: the movable die and the fixed mold. With the injection of the active portion of the movable mold machines (mostly the top of the side), the output end of the injection machine is generally inactive called fixed mold. Large part due to the fixed mold outlet of the mold is generally composed by two steel plates such structures it is also called a mold for the "two-plate mold." Two plate mold is a big outlet mold simplest structure. (2) a fine nozzle precision plastic mold: runner and gate is not the parting line, usually directly on the product, so you want to design a set of multi-outlet parting line, design is more complex, more difficult process, generally depending on the product requirements The selection of fine nozzle system. Fine nozzle fixed mold part mold is generally composed of three steel plates it also called for such structures Die "three plate mold." Three plate mold is fine nozzle mold simplest structure. (3) hot runner precision plastic mold: This mold structure and fine nozzle substantially the same, the biggest difference is that the channel has a thermostat in one or more of the manifold plate and heat pump mouth, no cold material stripping, channel and gate directly on the product, so the runner does not require a release, this system is also known as non-outlet system, which can save raw materials for raw materials more expensive, higher product requirements, the design and processing difficulties, high tooling costs . Hot runner systems, also known as hot runner system, mainly composed of hot sprue bush, hot runner plate, temperature control electric box. The most common hot runner system with a single-point and multi-point hot runner hot runner two kinds of forms. Single-point thermal gate directly to the molten plastic is injected into the cavity with a single hot sprue bush, it applies to a single gate single cavity plastic mold; multi-point thermal gate hot runner plate through the molten material to the respective branches sub hot sprue bush again into the cavity, which applies to single-chamber multi-point or multi-cavity mold feeding precision plastic mold:. http: //www.xkslm.com/cn/zpro_list_6_1.htm stamping die manufacturing: http : //www.xkslm.com distribution box: http: //www.yqyh.net Wenzhou kitchen equipment: www.wzjiemei.com red machine: http: //www.emepack.cc
