BMC INJECTIO MOLDING MACHINE
The processing tonnage of bmc injection molding machine refers to the clamping force, which refers to the clamping force exerted by the clamping mechanism of the injection molding machine on the mold. When it comes to clamping force, everyone will naturally mention the corresponding wear-resistant material pressure. When the pressure of the wear-resistant material is too high and exceeds the clamping force, this force will be able to push the mold away at this moment, and the product cannot be successfully trial-manufactured. Therefore, in order to ensure that the product is formed to meet the precision requirements, the clamping mechanism must have sufficient clamping force to clamp the mold.household plastic mold.
The processing capacity of the injection molding machine mainly depends on two main parameters-injection volume and clamping force. Therefore, the tonnage of the injection molding machine determines the processing capacity of the injection molding machine. Therefore, the injection molding machine is relatively small and medium-sized, small and medium-sized, small and medium-sized, large and medium-sized and relatively large. Detailed categories are thus found below. The clamping force (tonnage) is the same as the injection volume, and it also reflects the size of the injection molded product. It is an important parameter of the injection molding machine and one of the key conditions for bmc injection molding machine manufacturers to ensure the quality of plastic products. Therefore, many countries and regions use the clamping force as the specification for the model of the injection molding machine.
The average pressure of the mold cavity corresponding to different types of injection molded products PE, PP, PS and other products with thick walls and uniform and easy to form, the average mold cavity pressure generally used is 25MPa; under the environment of relatively high mold temperature, forming thick-walled containers Generally, the average pressure of the mold cavity is 30MPa; for parts with high precision requirements such as ABS and POM, the viscosity and precision of raw materials are strictly required, and the average pressure of the mold cavity is generally selected to be 35MPa; high-precision mechanical parts, such as plastic gears, etc. , this kind of product has high viscosity, difficult to fill the mold and has strict precision requirements. Generally, the average mold pressure of the bmc injection molding machine selected is 40-45MPa.
