Hot and Cold Runner System Molds Productions

Advantages of hot runner system mold:

1, Forming cycle

Because there is no limit to the cooling time of the runner system, the parts can be pushed out in time after forming and curing. Many thin wall parts produced with hot runner molds can be formed in less than 5 seconds.

A hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold. (The cavities are the part of the mold shaped like the parts to be produced.) In hot runner mould generally used pinpoint gate.

2, Conducive to production automation

The product is finished after the hot runner mold is formed, without pruning the gate and recycling the cold runner and other processes. Conducive to production automation. Many foreign manufacturers combine hot runner with automation to greatly improve production efficiency.

3. Expanding the project's Hanoi road project

Many advanced plastic molding processes are developed on the basis of hot runner technology. Such as PET preforming production, multi-color co-injection in the MOLD, multi-material co-injection process, STACK MOLD and so on.

Advantages of cold runner system mold:

1，Cold runner mold is helpful for efficient molding of LSR and improve the stability of injection molding of LSR. LSR can be molded with different materials for secondary molding, which is suitable for the production of fine parts and large parts. It is widely used in automobile, medical, maternal and child industries.

2.，The advantage of the cold runner system is that it is easy to use and can also well meet some aesthetic needs.

3，The cold runner can reduce the acrylic or polycarbonate and other parts of the injection channel used to transmit light, so as to avoid the visible ribbon effect caused by injection in some parts.
