Frequently Asked Questions
about Procurement

Xiamen Mellow Rotomolding Co., Ltd. delivers end-to-end, integrated plastics engineering services. The turnkey OEM/ODM workflow encompasses 3D product design, structural CAD engineering, custom aluminum/steel mold development, precision rotational molding, polyurethane foam insulation injection, secondary CNC machining, hardware integration, and global logistics. Beyond standard catalogs, custom mold development is supported for any specialized industrial plastic components.

Prime-grade LLDPE, HDPE, and UV-stabilized polyethylenes are primarily utilized. Seamless one-piece rotational molding eliminates stress points and weld lines, resulting in zero-leakage structures, high impact resistance, chemical corrosion immunity, and a 15+ year operational lifespan under severe marine and industrial outdoor environments.

Full custom tailoring is supported across all product lines. Custom options include bespoke Pantone color matching, molded-in or laser-engraved logos, custom foam inserts for Heavy-Duty Tool Boxes, marine-grade vinyl upholstery for seating, and pre-molded brass/stainless steel thread inserts for tank plumbing.

Operating under an ISO 9001-certified management system, rigorous quality assurance is maintained through in-house testing laboratories. Every production batch undergoes wall-thickness ultrasonic testing, drop-impact testing, hydrostatic pressure leak detection, and UV degradation resistance verification before dispatch.

Flexible MOQ structures are offered to accommodate OEM projects, custom mold trials, and wholesale distribution networks. Products are packaged using export-grade protective wrapping and steel-reinforced pallets, supported by complete sea/air freight documentation and door-to-door global logistics support.
