Main features of rubber injection machine and rubber injection machine screw barrel:

1. Simplify the process, rapid vulcanization of rubber products with high temperature, shorten the production cycle;

2. The product size is more accurate, the physical and mechanical properties are more uniform, with better quality, which is especially suitable for the molding of thick-walled products;

3. Simple operation,less labor operation, high degree of mechanization and automation;

4. Complicated mechanism of rubber injection machine, complicated mold, big investment, high level of technical maintenance, suitable for production of large-scale molded products;

Quality Inspection

Quality is a very important step during production. For making a quality screw barrel, all tolerances should be fulfilled and all dimensions should be correct and put in records.

We provide inspection report, material certificate for every of our supplied screw barrels.


Packaging

Packaging is the last but very important step before shipping. A strong and smart packing box is also part of our quality. It is not only used to protect the screws barrels well during transportation, also provide an easy way for our customer to unpack.
