Connectors, circuit breaker housings, relay bases, coil bobbins, and insulating sleeves (UL94 V-0).
Power tool housings, garden tool parts, luggage handles, sports equipment components, and furniture glides.
Nylon push clips, retaining rings, snap-fit fasteners, cable clips, and custom buckles.
Water pump impellers, filter housings, valve bodies, and fuel system components (gasoline-resistant nylon grades).
Challenge: High-heat engine compartment cover needed dimensional stability at 150°C and ribbed structure for rigidity. Volume: 200,000 units/year.
Solution: Designed a hot runner mold with optimized cooling; used PA66+GF30 (heat stabilized). Integrated brass inserts for mounting bolts.
Result: Cycle time reduced by 18%, zero warpage issues, passed 2000h heat aging test.
Challenge: Customer needed a UL94 V-0 rated connector housing with thin walls (0.8mm) and precise dimensional tolerance (±0.02mm) for pin alignment.
Solution: Used halogen-free flame-retardant PA66, high-precision multi-cavity mold with valve gate hot runner.
Result: Consistent part geometry, passed glow wire test (GWFI 960°C), delivered 500k pieces with zero defects.
Challenge: Existing metal guides caused chain wear and noise; required self-lubricating nylon with low friction and high abrasion resistance.
Solution: Custom compounded PA6 + PTFE + MoS₂, injection molded in 2m length with integrated mounting slots.
Result: Noise reduced by 30 decibels, chain life extended by 400%.

We are not a trading company. Mold design, mold making, injection molding, and secondary operations all under one roof. This ensures faster iterations, lower costs, and total traceability.
24/7 production capable of 5 million+ shots/month. Short lead times: 15 days for engineering prototypes, 30-40 days for production tools.
DFM (Design for Manufacturing) feedback, FMEA analysis, and cost-down suggestions. We help you optimize part geometry, gate location, and material grade to reduce overall project cost.
Simple prototype molds (aluminum) can be ready in 15–20 days. Production-grade steel molds typically require 30–45 days depending on complexity and number of cavities.
Heat-stabilized PA66 or PA46 (Stanyl) with 30-35% glass fiber. They offer continuous use up to 180°C and excellent creep resistance.
Yes. We use flame-retardant compounds that maintain V-0 rating even with color masterbatches. Full UL yellow card documentation available.
Absolutely. Our engineering team performs FEA simulation to redesign metal brackets, housings, or gears into lightweight, corrosion-resistant nylon components.
No strict MOQ — we accept small pilot runs (500-2000 pcs) for validation. High-volume discounts apply for orders above 50,000 pcs.
We use dehumidifying dryers to reduce resin moisture below 0.1% before processing. In-process humidity monitoring and sealed packaging prevent post-molding moisture absorption.
Send us your 3D drawing (STEP/IGS) or sample part. Our engineers will review DFM, recommend material grade, and provide a competitive quotation within 48 hours.
