INBORN offers two primary mold types: aluminum molds and steel molds. Aluminum molds are renowned for high precision, mirror polish, and long service life (over 5,000 molding cycles). They are ideal for large and complex hollow products such as storage tanks, cabinets, and boats. Steel molds, on the other hand, are cost-effective with excellent thermal conductivity and high temperature resistance, making them suitable for extra-large products with low production volumes. Their mold design capability includes optimized parting line design, precise insert control (gap ≤ 0.2mm for aluminum molds), and demolding-friendly structures.
From mold design and fabrication to production, assembly, packaging, warehousing, and international logistics (sea freight, air freight, courier), INBORN provides full-range services. Extended processes cover prototype sampling to mass production. Strict tolerance control ensures insert gaps ≤ 0.2mm for aluminum molds and ≤ 1.5mm for steel molds.
