Five characteristics of hot runner mould
Hot runner mould is widely used in industrial developed countries and regions in the world.This is mainly because the hot runner mould has the following remarkable characteristics:
1. Shorten the casting cycle
Because there is no restriction on the cooling time of the runner system, the parts can be produced in time after being formed and solidified.Many thin-walled parts produced by hot runner moulds can take less than five seconds to shape.
2. Save plastic materials
There is no cold runner in the pure hot runner mould, so there is no production charge.This is especially significant for expensive applications of plastics.In fact, the world's major manufacturers of hot runner in the world oil and plastic raw materials are expensive era of rapid development.Because hot runner technology is the effective way to reduce cost of materials and materials.
3. Reduce waste products and improve product quality
The temperature of plastic melt is accurately controlled in the system of the hot runner mould.Plastics can flow more uniformly into each cavity, resulting in parts of uniform quality.The quality of the part gate is good, the residual stress is low and the part deforms little.Therefore, many high-quality products on the market are produced by hot runner mold.Many of the plastic parts in familiar MOTOROLA phones, HP printers and DELL laptops are made from hot runner molds.
4. Eliminate subsequent processes, which is conducive to production automation.
After the hot runner mold is formed, the finished product, without the need to trim the gate and recycle the cold runner.Facilitate production automation.Many foreign manufacturers combine heat runner with automation to improve production efficiency.
5, expand the injection molding process application 笵 circumference
Many advanced plastic forming processes are developed on the basis of hot runner technology.For example, PET preformed production, multicolor co-injection in the mold, multi-material co-injection process, STACKMOLD, etc.
