Application Overview — Injection molding is used to manufacture repeatable, high-volume plastic components with complex geometry, controlled dimensions and varied surface finishes. Resin selection must consider wall thickness, flow length, impact, service temperature, chemical exposure, appearance, compliance and assembly.
Typical Products — • Thin-wall food containers, caps and closures • Household, storage and appliance components • Electronic and electrical housings • Automotive parts • Gears, bearings, clips and fasteners • Connectors, switches and bobbins
Key Performance Requirements — • Melt flow matched to wall thickness and tooling • Stiffness-impact balance and dimensional stability • Heat and chemical resistance • Surface quality and colourability • Wear and friction performance • Electrical, flame and regulatory requirements where specified
Material Selection Guide — • PP Homopolymer: caps, rigid housewares and high-stiffness parts • PP Random Copolymer: transparent containers and clear housewares • PP Impact Copolymer: durable containers, appliances and automotive parts • ABS: appearance housings and impact-resistant parts • PC/ABS: higher-performance enclosures and automotive interiors • PA6 / PA66: structural, heat-resistant and wear parts • POM: gears, bearings, clips and precision mechanisms • PBT: connectors, switches and dimensionally stable electrical parts • PC: transparent covers and impact-resistant housings

Selection Notes — Start with the finished part drawing, dimensions, wall thickness, part weight, cavities and gate design. Define temperature, impact, chemical contact, exposure and service life. Final approval must be based on the manufacturer’s current TDS, regulatory documents, molding trials and finished-part validation.
