6 industries,
one machine for
many materials.

From a serial number on a phone case to a 0.5 mm deep-engraved code in mould steel — Zhongyi Laser covers six industries with UV, fiber and CO₂ lasers, vision positioning, spot welders and CO₂ cutters. Every industry lists its recommended machine, so picking the wrong power gets much less likely.

Six industries,
covering the main materials.

Each tile marks the recommended machine for that industry. Most industries run more than one material — the final choice follows a real sample test.

Footwear & Textile

Leather & textiles

Cowhide, synthetic leather and white soles all mark cleanly. What matters most is no damage, no yellowing, no feel — the surface stays flat, the mark survives flexing, and it suits upper logos, size marks and anti-counterfeit codes.

Watches & jewellery

Timepieces & jewellery

Tiny characters and logos on case backs, clasps, spectacle frames and the inside of gold and silver jewellery. Line width down to 0.015 mm and still legible inside a 3 mm square — suited to shallow engraving on precious metal and marking on sapphire crystals.

Automotive parts

Automotive traceability

Permanent marks for VIN plates, engine numbers and part traceability codes — heat resistant, oil resistant, wear resistant, and they last the whole vehicle life. Rubber and silicone parts such as seals and hoses mark just as cleanly.

Building & ceramics

Ceramics & sanitaryware

Brand marks and batch codes on tiles, sanitaryware and ceramic crafts. The glaze edge does not chip or blacken, and on dark glaze the mark reads light and high-contrast — replacing stickers and screen printing.
