Product Description

PLA Biodegradable sheet make machine long life and high output

(1) Introduction to GWELL machine

Gwell plastic transparent sheet unit production line absorbs and digest western country advanced extrusion technology. And its main parts choose from all over the world (such as screw, barrel, roller, etc.). The energy consumption of its complete sets of equipment , intelligent, automation, safety standard, technology standard, etc., have been at or near the world standard of the product. This series of products has a number of inventions and utility model patents so that it replaces imported equipment, and has a cost-effective advantage.Its quality has reached the world's product performance, and we have a matching team of experts and process engineers to help users debug, produce high-quality products.

(2) Twin-screw combination technology

Years of experience in R&D and design of twin-screw configuration are optimized and combined with advanced software technology. Special double-threaded elements and unique screw combinations can realize conveying plasticization, mixing and kneading, shearing and dispersing, homogenizing, exhausting, pressure building and extrusion and various functions. Especially for the removal of crystal water inside the PLA material, it has a very high efficiency. The specially designed exhaust port does not emit material, and is free and unobstructed. It realizes low-temperature extrusion and avoids thermal degradation of PLA;

(3) Vacuum exhaust technology

Multi-stage forced exhaust is efficient and safe to ensure that the PLA material will not be hydrolyzed or crystallized during the melting and plasticizing process. Special three-stage vacuum exhaust technology and oil-gas separation technology, super large pumping capacity and super high vacuum, greatly reduce the viscosity reduction of PLA.

(4)Spiral flow channel technology inside the high-strength roller

The internal spiral flow channel structure design of the high-strength roller is equipped with a water temperature control system, so that the roller has precise temperature control and efficient heat transfer effects;
