Inborn Plastic Industrial (Ningbo) Ltd, commonly known as INBORN, stands out as a premier one-stop solution provider for rotomolding molds and finished products. With over 20 years of industry experience, INBORN has established itself as a trusted name in the global rotational molding market.

INBORN positions itself as a specialist in cost-effective rotomolding customization for small and medium batches. The company serves mid-to-low and mid-end markets, excelling in medium-sized, irregular-shaped structural and appearance parts. Their target clients span diverse industries, including automotive, agricultural machinery, engineering machinery, marine and boat, home appliances, medical equipment, outdoor furniture, and amusement facilities. With a young, efficient team and 24-hour prompt support, INBORN ensures stable delivery capacity and quick response times, making them a reliable rotational molding company from China.
INBORN offers both cast aluminum molds and steel molds, each tailored to specific production needs. Cast aluminum molds provide high precision with mirror polish and exceptional longevity—exceeding 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, offer excellent thermal conductivity and high-temperature resistance, and are suitable for extra-large products with low production volumes. The company’s mold design capability ensures optimized parting line design, precise insert control (gap ≤ 0.2mm for aluminum molds), and demolding-friendly structures. For steel molds, insert gaps are maintained at ≤ 1.5mm. Lead times for aluminum molds range from 15–20 days, while steel molds offer a longer service life of 5–10 years, making them perfect for mass production of thick-walled, pressure-resistant products.
INBORN manufactures a wide array of rotomolded products using primarily LLDPE and HDPE materials, which are UV-resistant, weatherable, and suitable for food-grade applications. Their product categories include:

All products feature acid and alkali resistance, anti-aging, impact resistance, waterproof and leakproof properties, and lightweight construction. For outdoor furniture, INBORN offers illuminated tables and chairs, casual seats, and bar counters made of eco-friendly PE material that is both waterproof and weather-resistant.
INBORN’s one-stop service model covers the entire production lifecycle—from mold design and fabrication to product manufacturing, assembly, packaging, warehousing, and international logistics (sea freight, air freight, and courier). The company provides full solutions from prototype sampling to mass production, ensuring seamless transitions between stages. Their team of skilled professionals quickly delivers tailored solutions, leveraging nearly 20 years of dedicated rotomolding expertise. This integrated approach results in a lead time that is over 20% shorter than industry peers, with lower overall costs.
INBORN’s technical strength lies in its experienced mold designers who excel at solving challenges in complex molding, insert embedding, and surface texture treatment. The company uses premium materials—mainly food-grade LLDPE and HDPE—that meet European and American standards for RV and drinking water applications. Quality control is rigorous: raw material sampling, mold trial, first article inspection, in-process patrol inspection, and final inspection are all part of the process. Key parameters like tightness, wall thickness, and dimensions are recorded and traceable. Additionally, molds are finished with mirror polish and precise gap control, and PTFE plates are equipped for easy demolding and material saving.
