Why hot runner molds are widely used
May 30, 2018

Hot runner molds have been widely used in various industrialized countries and regions in the world today. This is mainly due to the following salient features of hot runner molds:

1, shorten the molding cycle

 Because there is no restriction on the cooling time of the runner system, the parts can be ejected in a timely manner after being cured. Many thin-walled parts produced with hot runner molds can be molded in less than 5 seconds.

2, save plastic raw materials

Because there is no cold sprue in the pure hot runner mould, there is no production cost. This is particularly significant for plastics expensive applications. In fact, the major hot runner manufacturers in the world have achieved rapid development in the world when petroleum and plastic raw materials are expensive. Because hot runner technology is an effective way to reduce material costs and material costs.

3, reduce fees and improve product quality

Hot runner molds have been successfully used to process a variety of plastic materials. Such as PP, PE, PS, ABS, PBT, PA, PSU, PC, POM, LCP, PVC, PET, PMMA, PEI, ABS/PC, etc. Any plastic material that can be processed with a cold runner mold can be processed with a hot runner mold.

4. Wide application of industrial fields

Hot runner molds are widely used in various industrial sectors such as electronics, automotive, medical, daily necessities, toys, packaging, construction, and office equipment.

In injection molding, it has quite a few unparalleled advantages. As technology matures and manufacturing costs decrease, hot runner technology will increasingly show tremendous advantages. In recent years, the world-famous hot runner technology suppliers have successively entered the Chinese market in various ways. This shows that China's hot runner mold market has great potential for development.
