The outer diameter dimensions at the time of the new product have been revived with skilled craftsmanship... polishing of the screw buildup area.

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!

  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!
