Button

Buttons are manufactured from 316L stainless steel via MIM molding, precision polishing and PVD coating for audio equipment.

MIM one-step forming fabricates delicate mini button structures with high sintered density and tight dimensional tolerance, eliminating splicing defects from traditional machining.

Sintered 316L blanks receive fine polishing to form smooth uniform substrates with outstanding corrosion resistance for frequently touched audio exterior parts.

After precise deburring and surface leveling, uniform ultra-thin PVD hard coating covers all miniature edges, boosting scratch resistance and decorative texture without interfering with assembly clearances.
