Screws & Barrels

In the plastic extrusion process (LVT extrusion process), when problems such as unstable discharge, bubbles, voids, or inconsistent quality occur in products, many companies often first try to adjust the temperature, screw speed, or raw material formula. However, if the problems continue without improvement, what truly needs to be examined is whether the screw and barrel system meets the process requirements for raw material characteristics and feeding stability.

With shifting times and rising health consciousness, consumers—whether for themselves or their pets, and regardless of a vegan or meat-based diet—value nutritional content and balance. From plant proteins  to healthy snacks infused with superfoods, the food industry is undergoing a "Nutrition Revolution".
