Tractor roof

Agricultural machinery is exposed to the sun in the fields all year round, drenched by rainstorm, splashed with mud, scratched by branches, and vibrated by jolts. The ceiling is most afraid of heavy rust of iron sheet, loud resonance noise, uneven wall thickness of hand laid FRP and easy cracking. Injection molding can not do large-scale overall molding - the splicing joint is the point of rain leakage and cracking. Rotational plastic ceiling is integrally formed without joints, no leakage in rainstorm, uniform wall thickness and resistance to turbulence, double-layer structure can be foamed, heat insulated and cooled, UV resistant and resistant to pesticide and fertilizer corrosion, arc molding without dead corners, low cost of aluminum mold, and fast adaptation and modification of multiple models.
