1. High Tooling Costs Delaying Production: Traditional mold development can take 8-12 weeks and cost $50,000+ for complex parts. According to a 2026 Grand View Research report, 68% of manufacturers cite tooling lead times as their biggest bottleneck.
2. Quality Inconsistencies Across Batches: Without precise process control, LSR parts can show ±0.5mm dimensional variations, failing medical/automotive standards. The Fraunhofer Institute found that 40% of silicone part defects stem from improper mold venting and curing control.
3. Supply Chain Fragmentation: Coordinating mold makers, material suppliers, and production across vendors adds 20-30% overhead. Our integrated 35,000m² facility eliminates this by handling everything from prototyping to mass production under one roof.

OEM Injection Molding FAQs (Answered by Our Engineers)
💡 Material Selection
Q: What's the difference between LSR and solid silicone for injection molding?
A: LSR (Liquid Silicone Rubber) offers faster cycle times (15-60s vs. 2-5min), higher precision (±0.01mm), and automation compatibility. Solid silicone requires compression molding and has higher labor costs. Per a 2026 MDPI study, LSR achieves 99.9% defect-free rates in high-volume production.
Q: Can you mold food-grade silicone parts?
A: Yes. Our platinum-cure LSR meets FDA 21 CFR §177.2600 and EU 10/2011 standards. We've supplied silicone baking molds to IKEA and KitchenAid for 8+ years with zero compliance issues.
💡 Tooling & Prototyping
Q: How long does a production mold last?
A: Our hardened steel molds guarantee 1-5 million shots for LSR and 500K-1M shots for engineering plastics. Aluminum prototypes achieve 10K-50K shots for pilot runs.
Q: What's your prototype lead time?
A: 7-10 days for LSR (using rapid tooling) and 5-7 days for plastic prototypes. Protolabs reports that 78% of manufacturers consider 2-week prototypes "slow" in 2026.
💡 Production & Logistics
Q: What's your minimum order quantity (MOQ)?
A: No MOQ for prototyping. Mass production starts at 1000 units for LSR and 500 units for plastics. We offer consignment stock for long-term partners.
Q: How do you ensure quality control?
A: Every part undergoes:
- 100% visual inspection (automated cameras)
- Dimensional checks (CMM, optical comparators)
- Material verification (FTIR spectroscopy)
- Functional testing (pressure, leak, durability)
💡 Customization & Support
Q: Can you help with part design?
A: Yes. Our DFM (Design for Manufacturing) team provides:
- 3D mold flow analysis (Autodesk Moldflow)
- Wall thickness optimization
- Draft angle recommendations
- Material selection guidance
Q: What after-sales support do you offer?
A: Lifetime mold maintenance, 24/7 technical support, and on-site engineering visits for critical issues. We keep spare molds in stock for high-volume customers.
