RA900 Industrial 3D Printer for Tyre Mould Mass Production

RA900 – a dual-laser SLA printer purpose-built for tyre mould mass production; 950 × 550 × 400 mm build volume, four medium-sized tread moulds in 36 h (<10 h per mould), replacing traditional CNC workflows that take 2–3 weeks. RA900 ships with UnionTech’s UT-ONE software for one-click nesting and support generation; achieves Ra <3.5 µm surface finish, ±0.08 mm dimensional accuracy and <0.05 mm roundness deviation, point deviation < 95% —critical for ventless, insert-free tyre moulds. Continuous-run stability exceeds 95 %, enabling zero-inventory, lot-size-one manufacturing.
Larger Size Higher Efficiency

Ultra-fine printing: Surface roughness Ra < 3.5; roundness deviation≤ 0.05 mm; dimensional accuracy ±0.08 mm; point deviation < 95%; specially optimized for complex tire tread patterns

Efficient production: Dual-laser configuration with customized build volume (950 × 550 × 400 mm) for tire mold manufacturing, capable of printing 4 tire base molds simultaneously

Operational Stability: Yield in continuous operation > 95%; long-term operational stability due to a new enclosed optical path system

Intelligent operation: UT ONE – ‘One for All’ optimized printing processes: enable automatic sample placement and support generation, and intelligent production scheduling
