Product Description

PET Screw and Barrels for Injection and Extrusion

PET resin has poor thermal stability, and is easy to hydrolyze. It is often added pigments such as color oil and color masterbatch, thus is easy to produce excess formaldehyde gas that will acidize during the injection molding, which is typical in the bottle preform molding industry. With the popularity of lean production, the screw structure tends to low-shear - high mixing.
After years of research and development and practical analysis, the single melt tank is divided into high- and low-pressure areas to form a wavy structure, in substitution of solid and liquid tanks, so that the melt will shunt itself in this area without hindering the travel time, thus achieving the best energy-efficiency ratio.
