Polyurethane Turnover Box
Our polyurethane (PU) turnover boxes serve the photovoltaic (PV) and polysilicon industries with a high-performance alternative to HDPE, PP, ABS, and metal boxes. They protect fragile silicon ingots, rods, wafers, and recycled materials during every handling step. Each PU box delivers strong impact resistance, stable chemical performance, reliable anti-static protection, and precise dimensions. These features keep materials intact and support smooth operation on automated production lines.
Polyurethane Turnover Boxes for Photovoltaic Silicon Ingot & Wafer Manufacturing
PU turnover boxes absorb impact forces to prevent micro-cracks, chipping, and edge damage during handling and transport. This is especially critical for monocrystalline rods and wafers during cutting, grinding, polishing, and cleaning processes. The elasticity of polyurethane helps cushion shocks while maintaining dimensional stability under repeated use.
