INBORN specializes in two primary mold types: aluminum and steel. Their aluminum molds are known for high precision, mirror polish finish, and an extended service life exceeding 5,000 molding cycles. They are ideal for large and complex hollow products such as storage tanks, cabinets, and boats. The mold design capability includes optimized parting line design, precise insert control with a gap tolerance of ≤ 0.2mm, and demolding-friendly structures. These features ensure easy operation, efficient cleaning, and consistent product quality. For clients requiring cost-efficient solutions for small and medium-sized appearance parts, cast aluminum molds are available with a short lead time of 15–20 days and a maximum dimension of 2.5m with tolerance of ±0.1mm.
For extra-large products with lower production volumes, INBORN offers steel molds that are cost-effective and possess excellent thermal conductivity and high-temperature resistance. Steel molds have a long service life of 5–10 years and are suitable for thick-walled, pressure-resistant products in mass production. Insert gap tolerance for steel molds is ≤ 1.5mm, and they can handle demanding applications in automotive, marine, and industrial sectors. The company’s mold design team ensures that even complex parting lines are well designed for easy operation and maintenance.
INBORN’s professional mold designers have rich industry experience, ensuring reliable quality and high production efficiency. They excel at solving challenges in complex molding, insert embedding, and surface texture treatment. The company uses advanced 3D design software and can work from client drawings, samples, or design concepts. Strict tolerance control and mirror polish finishing are standard. Additionally, PTFE plates are equipped for easy demolding and material saving, further reducing production costs.
INBORN provides comprehensive one-stop services that cover the entire product lifecycle. This includes mold design and fabrication, product manufacturing, assembly, packaging, warehousing, and international logistics via sea freight, air freight, or courier. The company’s extended processes range from prototype sampling to mass production, ensuring a seamless transition from concept to final product. Clients benefit from a single point of contact for all needs, which reduces lead times by over 20% compared to industry peers and lowers overall costs.
Full-process quality control is a hallmark of INBORN. The company performs strict inspections at every stage: raw material sampling, mold trial, first article inspection, in-process patrol inspection, and final inspection. All key parameters are recorded and traceable. They primarily use food-grade LLDPE and HDPE materials that feature UV resistance, weatherability, and acid & alkali resistance, meeting European and American standards for applications like RV water tanks and drinking water containers. The company also offers material expertise in modified PE and other dedicated rotomolding materials, providing customized solutions for color matching, UV resistance, and food-grade requirements.
INBORN manufactures a wide array of rotomolded products, categorized into several groups.
Their outdoor furniture line includes illuminated tables and chairs, casual seats, and bar counters, all made from eco-friendly PE material that is waterproof and weather-resistant. These products are popular in parks, restaurants, and hospitality settings.
