WINDOW Raw Materials

Before Print : Removes alien substances and washed for good quality precise cutting.

Print : Prints according to requirements of customers, and dries with heat(including vaccum-metallizing and stamping)

3-dimension manufacturing : Manufactures Acryl products using CNC engraver.

Before Assembling : Inspects electrotype-products and tape jig operation for both sides.

Assembling : Assembles electrotypes with Acryl products.

It enables acryl forming of 3-dimension R value,and it contributes cost reduction and fast correspondence. In-mold injection - D-25, Acryl forming - (6~7)
