Hand diamond polishing delivers flawless, mirror-like finishes for injection molding tools – providing the perfect surface to deliver high quality plastic parts. When used with CNC machining or EDM, hand polishing ensures your molds maintain tight tolerances and exceptional durability.

At Bales, our team uses diamond abrasives to meticulously polish mold cavities and cores, achieving ultra-smooth surfaces that automated systems can’t match. Our hands-on approach provides precise control over complex shapes and intricate details, making sure every mold meets your high standards.
