The precision range of tablet computer mould: 0.02mm!

The tablet computer mould is a plastic mould produced by Dongguan Equation Precision Mould Parts Co., Ltd. The use of high-gloss seamless injection molding technology and steam-assisted technology makes the plastic product perfect.

High-gloss seamless injection molding technology:
Steam-assisted process makes plastic products perfect from now on
For surface etched surface
The surface of the product has no welding marks, no flow marks, no flow lines, no sink marks, the surface is more perfect, the plastic composition is harder, and it is not easy to scratch, which can avoid the high-cost oil spraying process of various marks on the surface.
For high-gloss surfaces
Make the surface of the product brighter, leaving no trace on the surface, and the plastic component is harder. It is more beautiful, smooth and bright than the surface sprayed with UV oil, and the cost is lower
Steam assisted molding
Eliminate surface welding lines, no need for subsequent tin spraying processing, enhance material flow filling effect, improve production efficiency, improve surface finish, make it achieve mirror effect, and solve the phenomenon of floating fibers caused by fiber addition
Texture and etching
Use chemicals to corrode the inside of the plastic molding mold. After molding, the surface has corresponding lines. Dongguan Equation Precision Mould Parts Co., Ltd. provides customers with mold patterning and drawing lines, various types of molds and etching, which effectively solve the problem of moulds.
