We have die-casting processing methods such as sand casting and casting, and we are also equipped with advanced 3-axis, 4-axis, and 5-axis CNC machining centers, which can process various parts that require high precision and complex shapes. With extremely tight tolerances and excellent surface finish.


Processing Type smooth Semi-gloss matte Textured
Precision Die Casting A grade finish is made with a diamond polishing process that produces a shiny finish on injection molded parts. Grade B finishes use coarse sandpaper to produce rougher parts than Grade A parts. Custom-molded plastic parts with a B-grade finish have a matte surface texture. Grade C finishes use coarse grit to create a rough, uneven surface. C-finished injection molded parts have a matte surface texture. Grade D finishes use grit and dried glass beads or oxides to create a very rough textured finish. Depending on the type of material used, the product can have a satin or matte finish.
