For wear-resistant screws, we recommend a bimetallic liner!
The cylinder liner is the most important component in injection molding machines and extruders. It not only transmits thermal energy to the resin and screw but also supports the harsh operation of the screw, playing a role in enabling a good screw to exhibit better transport capacity with good resin conditions. No matter how good the screw is replaced with, it is meaningless if the inner diameter of the cylinder liner is worn. It can lead to stagnation, reduced transport capacity, and even promote screw wear. When replacing the screw, it is recommended to measure the inner diameter of the cylinder liner.

basic information
In recent years, with the diversification of plastic applications, there has been an increase in uses aimed at improving physical properties through polymer blends and the addition of fillers. The demands on screws have shifted from "plasticization" to "mixing," focusing on high quality, cost reduction, and the use of recycled materials. By reviewing and improving each process and component, including not only screws but also cylinders, dies, and hoppers, Martec leverages its extensive achievements and know-how as a comprehensive trading company for machine parts to contribute to your company. If you are in charge of technology for extrusion and molding machines, you may have considered upgrading the capabilities of existing screws and cylinders at least once! What happens when the main components, screws and cylinders, no longer perform as expected (as calculated)? At Martec, we offer regeneration through stellite overlay, colmonoy overlay, and the use of corrosion and wear-resistant materials, as well as various repair methods such as overlay welding, thermal spraying, special plating, and heat treatment, allowing for composite construction! With skilled craftsmanship, the results will be astonishing!
