INBORN’s philosophy centers on customer orientation, detail excellence, and delivery priority. They offer transparent pricing with no hidden costs, packaging fees included, and only freight charged separately. Their products are exported worldwide, backed by a strong reputation in the US, Europe, and Australia.
INBORN manufactures two primary mold types: cast aluminum and steel molds. Their aluminum molds are known for high precision, mirror polish, and a long service life exceeding 5,000 molding cycles. With a maximum dimension of 2.5m and tolerance of ±0.1mm, they are ideal for large and complex hollow products like storage tanks, cabinets, and boats. Steel molds offer cost-effectiveness, excellent thermal conductivity, and high temperature resistance, making them suitable for extra-large products with low production volume. Service life for steel molds is 5–10 years. Mold design capabilities include optimized parting line design, precise insert control (gap ≤ 0.2mm for aluminum, ≤ 1.5mm for steel), and demolding-friendly structures. Lead time for aluminum molds is 15–20 days; for steel molds, it varies.
INBORN produces a wide range of rotomolded products using LLDPE and HDPE materials, often with food-grade, UV-resistant, and weather-resistant properties. Key product categories include outdoor furniture (illuminated tables, casual seats, bar counters), industrial containers (water tanks, chemical tanks, insulation boxes, logistics bins), transportation and marine products (rotomolded boats, buoys, anti-collision facilities, road barriers), and customized parts for automotive, agricultural, and amusement industries. Products are characterized by acid and alkali resistance, anti-aging, impact resistance, waterproofness, and lightweight construction. The company also offers extended processes from prototype sampling to mass production, including assembly, packaging, and warehousing.
INBORN’s skilled team of professional mold designers brings nearly 20 years of experience in rotomolding mold design. They excel at solving challenges in complex molding, insert embedding, and surface texture treatment. The company is proficient in materials like LLDPE, HDPE, and modified PE, providing customized solutions for color matching, UV resistance, and food-grade applications. Molds are finished with mirror polish and precise gap control, with PTFE plates for easy demolding and material saving. Their quality control follows strict procedures: raw material sampling, mold trial, first article inspection, in-process patrol inspection, and final inspection. All key parameters are recorded and traceable, ensuring consistent product quality.
INBORN’s products serve diverse applications. In marine and boating, they provide small rotomolded boats, buoys, yacht fuel tanks, and dock bumpers resistant to seawater and UV. For automotive and agricultural machinery, they make fuel tanks, urea tanks, and equipment housings that are oil-proof and weather-resistant. Environmental protection includes septic tanks, sewage barrels, and sanitation bins. Outdoor and amusement areas benefit from park planters, tables, and children’s play facilities. Cold chain logistics uses insulation boxes and fresh food containers with food-grade compliance. Medical and home appliances use antibacterial, lightweight housings.
INBORN offers a complete range of aluminum and steel molds, along with one-stop services covering design, mold making, trial production, and mass production. This integration reduces lead time by over 20% compared to peers, lowering overall costs.
