As a high quality rotational mold manufacturer from China, INBORN ensures maximum dimension up to 2.5m with tolerance ±0.1mm. The mold design capability includes well-designed parting lines for easy operation and cleaning, with strict tolerance control: insert gap ≤ 0.2mm for aluminum and ≤ 1.5mm for steel. Additionally, PTFE plates are equipped for easy demolding and material saving.
INBORN offers full-range services from mold design and fabrication to product manufacturing, assembly, packaging, warehousing, and international logistics (sea freight, air freight, courier). This includes extended processes like prototype sampling to mass production, ensuring you have a seamless experience. The company's skilled and experienced team can quickly deliver tailored solutions, and their transparent pricing includes packaging fees—only freight is charged additionally, with no hidden costs.
