INBORN’s operations are divided into two primary areas: rotomolding molds and finished products. Under molds, they offer both aluminum and steel options. Aluminum molds feature high precision, mirror polish, and a long service life exceeding 5,000 molding cycles—ideal for large, complex hollow products like storage tanks, cabinets, and boats. Steel molds are cost-effective, with excellent thermal conductivity and high-temperature resistance, suitable for extra-large products with lower production volumes. Their mold design capability ensures optimized parting line design, precise insert control (gap ≤ 0.2mm for aluminum molds), and demolding-friendly structures.
Beyond mold fabrication, INBORN provides full-range production services: product manufacturing, assembly, packaging, warehousing, and international logistics (sea, air, and courier). They support extended processes from prototype sampling to mass production. This integrated approach reduces lead times and overall costs for clients.
