The outer diameter dimensions at the time of the new product have been revived with skilled craftsmanship... polishing of the screw buildup area.
By anticipating the wear amount during repairs and the allowance for grinding, skilled craftsmen achieve an astonishing complete restoration of shape!
The cylinders for injection and extrusion molding machines for plastics, which are becoming more complex and diverse due to the inclusion of metal powders, glass fibers, flame retardants, magnets, fine ceramics, and other materials in plastic molding materials, require performance characteristics such as wear resistance and corrosion resistance. Our company has a wealth of delivery experience backed by the material and processing technologies we have developed, and we have received positive feedback from various users. We will respond to all the "troubles" of equipment managers with a focus on advanced technology and high product quality.

basic information
There are various methods for plastic molding, but injection molding and extrusion molding are considered representative, and both use screws. The functions required of the screw include the ability to transport, melt, and knead (disperse), and in extruders, specialized screws designed specifically for the type of plastic being used are employed. On the other hand, in injection molding machines, a general-purpose screw designed primarily for melting (plasticization), traditionally referred to as a "plasticizing device," is used. If the screw, a major component, no longer performs as expected (as calculated)... To prevent a decline in production efficiency, quick and appropriate action is necessary for wear. At Martec, we offer regeneration through Stellite overlay, Colmonoy overlay, and the use of wear-resistant and corrosion-resistant materials, as well as various repair methods such as overlay welding, thermal spraying, special plating, and heat treatment, with the possibility of composite construction! With skilled craftsmanship, the results will be astonishing!

Applications/Examples of results
We can also create and repair various types of screws and cylinders. We also accept work such as the removal of broken screw heads. For example, we offer repairs for twin-screw cylinder liners with a minimum delivery time of 3 days... ideal for mixing resins that wear out quickly. Please feel free to contact Martec, which can handle all your "troubles."

Custom screws can also be manufactured! A 10% increase in discharge volume can result in a 20% loss if not achieved. Fixed costs remain almost unchanged. Please feel free to contact us for inquiries.
-
Post-weld heat treatment is important! Heat treatment after welding is essential to prevent defects such as cracks. The higher the hardness of the material, the more critical this process becomes. The skills of experienced craftsmen shine in this process as well!
