INBORN produces high-precision aluminum molds with mirror polish and a long service life exceeding 5,000 molding cycles. These molds are ideal for large and complex hollow products like storage tanks, cabinets, and boats. The insert gap is controlled to ≤0.2mm, ensuring excellent molding performance.
For cost-effective solutions, steel molds offer exceptional thermal conductivity and high temperature resistance. They are suitable for extra-large products with low production volumes. The insert gap for steel molds is ≤1.5mm, maintaining quality while reducing costs.
The factory's professional mold designers optimize parting line design for easy operation and cleaning. They excel at solving challenges in complex molding, insert embedding, and surface texture treatment. Mold lead time is 15–20 days for cast aluminum molds and slightly longer for steel, but overall, INBORN's lead time is over 20% shorter than industry average.
