There are some big differences between thin-walled plastic molds and ordinary molds, whether it is the structure of the mold or the cooling system, there are many differences, so today we talk about the thin wall plastic mold What are the differences between injection molding machines and ordinary conventional injection molding machines.
The conventional injection molding machine we use is difficult to use in the injection molding of thin-walled plastic parts. For example, the filling time of thin-wall injection molding is very short, and many filling times are less than 0.5s. It is impossible to follow the speed curve or cut-off pressure in such a short time. Therefore, a high-resolution microprocessor must be used to control the injection molding machine; During the entire injection molding process of the product, the pressure and speed should be controlled independently at the same time. The filling stage of the conventional injection molding machine is controlled by speed, and the pressure holding stage is converted to pressure control. The method is no longer applicable. Therefore, mechanical equipment manufacturers and research institutions work together to develop special injection equipment.
Thin-walled plastic molds can have today's achievements, and everyone's efforts are inseparable. In addition, plastic pipe fitting injection mould is constantly improving. In terms of mold manufacturing, the gap between my country and the world is still not small, but through continuous efforts, the gap is constantly shrinking, which shows how much effort everyone has put in.
