Thick mica plate processing parts
Product description

         
 In order to meet the market development needs, the company established a mica special-shaped parts processing supporting factory, introduced advanced processing and production equipment, with advanced CNC machine laser processing center, lathe, punch, milling machine, drilling machine, grinder, engraving machine and other professional processing machinery and equipment.

And more than 30 professional and technical personnel. 

Using mica as the base material, various processing methods such as coiling, punching, turning, drilling, grinding, milling, and model pressing are used. According to customer requirements, the mica plate can be processed into various sizes of mica pads, mica round pads, mica flanges, mica tiles, mica boxes, mica fixtures, mica plates of various sizes, mica plate slotting, drilling, angle, Slotted, I-shaped and other mica shaped parts. The temperature resistance above 800 has good mechanical strength and electrical performance under normal conditions. Suitable for high-temperature insulation of various industrial electric furnaces, industrial frequency furnaces, refining furnaces, intermediate frequency furnaces, calcium carbide furnaces, ferroalloys, yellow phosphorus furnaces, electric arc furnaces, power plants, electrolytic aluminum industrial frequency furnaces, intermediate frequency furnaces, electric arc furnaces, etc. Insulated with various electrical appliances, welding machines, lightning arresters, electric heating elements and other liners, with reasonable quality and reasonable price! The shape, size and thickness of the mica processed parts shall be agreed upon by the two parties provided by the user.
