For extra-large products with lower production volumes, steel molds provide a cost-effective solution. They offer excellent thermal conductivity and high temperature resistance, making them suitable for thick-walled and pressure-resistant items. With a lifespan of 5-10 years, steel molds are a durable choice for long-term projects. INBORN maintains insert gap tolerance of ≤1.5mm for steel molds, ensuring reliable performance.
INBORN's one-stop service model eliminates the need for multiple vendors. The company provides full-range support including mold design and fabrication, product manufacturing, assembly, packaging, warehousing, and international logistics via sea, air, or courier. Clients benefit from a seamless workflow that reduces lead times by over 20% compared to industry averages. The transparent pricing policy includes packaging fees in quotations, with only freight charged separately, ensuring no hidden costs.
With nearly two decades of rotomolding experience, INBORN's team of skilled engineers excels in solving complex molding challenges. The company's design capability covers intricate geometries, deep cavities, thin-walled parts, and insert embedding. Mold designers leverage advanced software to optimize parting lines and ensure demolding-friendly structures.
INBORN is proficient in a wide range of rotomolding materials, including LLDPE, HDPE, and modified PE. Customized solutions for color matching, UV resistance, and food-grade applications are readily available.
