INBORN specializes in two primary mold types: aluminum molds and steel molds. Aluminum molds are known for high precision, mirror polish, and a long service life exceeding 5,000 molding cycles. They are ideal for large and complex hollow products such as storage tanks, cabinets, and boats. Steel molds offer cost-effectiveness, excellent thermal conductivity, and high temperature resistance, making them suitable for extra-large products with low production volume. The company’s mold design capability includes optimized parting line design, precise insert control (gap ≤ 0.2mm for aluminum molds and ≤ 1.5mm for steel molds), and demolding-friendly structures.
| Mold Type | Material | Lead Time | Max Dimension | Tolerance | Best For |
|---|---|---|---|---|---|
| Cast Aluminum | Aluminum | 15–20 days | 2.5m | ±0.1mm | Small & medium-sized, appearance parts |
| Steel | Steel | Varies | 2.5m | ±0.1mm | Thick-walled, mass production |
INBORN’s molds are designed for easy operation and cleaning, with strict tolerance control. For aluminum molds, insert gaps are ≤ 0.2mm; for steel molds, ≤1.5mm, ensuring high-quality finished products.
