Surface finishes
Five finish programs
Different channels require different surface feel, corrosion resistance, and visual identity. HOYOTOOL runs the key finish programs inside the same manufacturing flow.
Finish selection is handled inside the same production program, so surface, corrosion resistance, logo clarity, and packing presentation stay aligned.
