What factors should be considered when choosing a barrel screw?

Several factors should be considered when selecting the cylinder screw of injection molding machine. First, the feed throat temperature must be sufficient. Too cold and volatiles will condense in the barrel. It's so hot that a film of molten film forms between the fins and the barrel walls. Trapped air can also cause parts to spatter or bubble. Proper feed throat temperature minimizes these problems. If these factors are not addressed, your parts may fail.

We have good screw barrel,high quality screw barrel.

Injection molding machine barrel screw is a kind of multifunctional tool used in plastic and metal processing. The diameter and length of barrel screw are the key factors affecting the overall quality of plastic parts. The size of the barrel should be suitable for the production capacity. A larger diameter will result in a higher quality product. The injection molding machine barrel screw will ensure that the final melt temperature is consistent.
