Adopting high-precision mirror surface polishing, the mold ensures excellent light transmission and uniform light effect without dark areas and light scattering. It accurately forms micro-prism and dot texture with strict dimensional tolerance. Professional shrinkage compensation and balanced cooling system effectively prevent product warping and deformation. Premium mold steel guarantees high hardness, corrosion resistance and long service life. Optimized demolding structure enables smooth ejection, no surface damage and high production yield.
