Enhancing the Performance of Metallic Parts
Maintenance Technical Center

Expertise in surface welding and thermal spraying in response to the needs of manufacturing sites requirements

  The Main-tech Center offers services to improve and enhance the performance of feeders, kneaders and other machinery and their parts for the rubber, plastic, paper, petrochemical and steel industries.

The metallic parts of the machines in kneading and extrusion molding processes require high level of corrosion, wear-abrasion, and heat resistance and insulation.
The Main-tech Center responds to these demands with its accumulated expertise and extensive know-how in surface welding and thermal spraying to coat the surface with foreign metals, ceramics, cermets and others suitable materials.

We provide repairs, overhauls and production of these metallic parts. One method of repair is by coating work pieces with a different type of metal, ceramics, cermets or other appropriate material to regain or enhance its usability.
