Product Overview
Our Professional Manufacturer Custom Plastic Parts Plastic Injection Molding Service offers high-quality, cost-effective solutions for industries requiring high-volume production and complex geometries. Using multi-cavity molds (up to 64 cavities) and high-speed injection molding machines (e.g., Haida HTF series with 50–500 tons clamping force), we produce ABS (impact-resistant), PEEK (high-temperature), and PP (chemical-resistant) parts with ±0.05 mm tolerance . From consumer electronics housings to medical device components, our solutions combine smooth surfaces (Ra ≤1.6 μm) with lightweight designs (30–50% lighter than metal alternatives), ensuring consistent quality at competitive prices.
Features
Precision Molding
Achieve ±0.03 mm dimensional accuracy on small parts (e.g., 10mm electrical connectors) and ±0.1 mm on large components (e.g., 500mm appliance panels) using CAE simulation (Moldflow) for filling analysis and hot runner systems (DME, Husky) for uniform melt distribution .
Support for insert molding (metal/plastic hybrids with pull-out force ≥50N) and overmolding (soft-touch TPE on rigid substrates with peel strength ≥1N/mm).
Material Diversity
Process engineering plastics (PEEK for 250°C continuous use, POM for low friction) and flame-retardant materials (UL 94 V-0 rated, LOI ≥28%) with minimum wall thickness of 0.8 mm (0.5mm with special tooling) .
Specialized handling for UV-resistant materials (ASA with 3% carbon black) using stabilized formulations that retain ≥80% tensile strength after 2000 hours of QUV testing.
Automated Production
Robotic part removal (6-axis robots with vision guidance) and 100% automated vision inspection (Keyence systems with 0.01mm defect detection) ensure <0.1% defect rate .
Mold temperature control (±1°C with water-based cooling) reduces warpage by 50% (to ≤0.5% of part length), enabling consistent part dimensions across production runs.
Surface Finishes
Offer texturing, painting (2K painting with gloss level 60–90 GU), and electroplating (nickel, chrome with adhesion tested to ASTM D3359) .
Medical parts undergo gamma sterilization (25–40 kGy) and biocompatibility testing (ISO 10993-5) for cytotoxicity, ensuring safety in clinical use.
Applications
Consumer Electronics: Mobile phone cases (drop-tested 1.5m onto concrete), laptop hinges (30,000+ cycle durability), and remote control housings (UV resistance for 5-year color retention).
Automotive: Dashboard trim (VOC emissions ≤100 μg/m³ for cabin air quality), door handles (temperature resistance -40°C to 85°C), and air vent components (chemical resistance to cleaning agents).
Medical: Disposable syringe barrels (USP Class VI compliant, dimensional accuracy ±0.05mm), diagnostic device housings (IP54 rated), and orthopedic braces (impact resistance ≥10 J).
Industrial: Valve bodies (chemical resistance to oils/solvents), conveyor system parts (wear resistance ≥10,000 cycles), and electrical enclosures (UL 94 V-0 flame rating).
Custom Service
Design for Manufacturability (DFM) Support: Free analysis of draft angles (minimum 1° for easy ejection), sink marks (≤0.1mm depth), and gate placement to optimize part geometry for molding, reducing tooling costs by 10–15%.
Rapid Tooling: Prototype molds completed in 7–10 days using aluminum tooling (7075-T6) for cost-effective low-volume production (100–500 parts), with steel inserts for high-wear areas.
Full Traceability: QR-code labeling linked to material certificates (ISO 10993 for medical, UL Yellow Cards for flame-retardant grades) and inspection logs (dimensional reports, visual checks) for regulatory compliance.
