According to Grand View Research, the global LSR market will reach $4.97 billion by 2030, yet 68% of buyers still overpay due to these critical errors:
❌ Mistake #1: Ignoring Mold Material Compatibility
LSR's high temperature resistance (200-250°C) and low viscosity require stainless steel (SUS304/SUS316) or aluminum (7075-T6) molds. Using standard P20 steel leads to:
- Corrosion from silicone byproducts
- Premature wear (LSR is abrasive)
- Flash defects (poor sealing)
Result: 40% higher rejection rates and 50% shorter mold lifespan.
❌ Mistake #2: Underestimating Venting Requirements
LSR's low viscosity (500-10,000 cP) traps air easily. Poor venting causes:
- Bubbles in final parts
- Incomplete filling (short shots)
- Burn marks from compressed air
Industry standard: Vent gaps of 0.01-0.05mm (vs. 0.02-0.1mm for plastics).
❌ Mistake #3: Overlooking Cure Time Optimization
LSR cures in 10-60 seconds (vs. 30-120s for thermoplastics). Incorrect curing leads to:
- Sticky parts (under-cured)
- Brittle components (over-cured)
- Cycle time waste (costing $5,000+/year in lost productivity)
Solution: Dynamic curing with platinum catalyst adjustment.

LSR Mold vs. Traditional Plastic Mold: Technical Comparison
According to MDPI’s study on LSR injection molding, choosing the wrong mold type can double production costs. Here’s how we stack up:
| Feature | Guangdong Yingtai LSR Mold | Traditional Plastic Mold | Competitor LSR Mold |
|---|---|---|---|
| Material Compatibility | ✅ SUS304/316, Aluminum 7075-T6 | ❌ P20 Steel (Corrodes with LSR) | ⚠️ Basic Stainless Steel |
| Venting Design | ✅ 0.01-0.05mm micro-vents | ❌ 0.02-0.1mm (Too large for LSR) | ⚠️ 0.03-0.08mm |
| Curing System | ✅ Platinum catalyst + dynamic curing | ❌ Not applicable | ⚠️ Basic platinum |
| Flash Prevention | ✅ 3-stage locking + vacuum assist | ❌ Single-stage locking | ⚠️ 2-stage locking |
| Cost Efficiency | ✅ 20-30% lower (China’s supply chain) | ❌ High (Western suppliers) | ⚠️ 10-15% lower |
| Lead Time | ✅ 30 days | ❌ 60-90 days | ⚠️ 45-60 days |

FAQ: Liquid Silicone Package Metal Parts Mold Manufacturing
❓ What materials do you use for LSR molds?
We use SUS304/SUS316 stainless steel for high-volume production and 7075-T6 aluminum for prototyping. Both are corrosion-resistant and optimized for LSR’s high-temperature curing (200-250°C).
❓ Can you handle LSR overmolding on metal parts?
Yes! Our 2-shot molding process bonds LSR to aluminum, stainless steel, and brass with adhesion strengths >12 MPa. We use plasma treatment for maximum bond reliability.
❓ What’s your minimum order quantity (MOQ)?
No MOQ for prototyping (1-10 molds). For mass production, we recommend 100+ molds to optimize costs. Samples are free (shipping costs apply).
❓ How do you ensure quality for medical-grade LSR molds?
All medical molds undergo:
- 100% inspection with Zeiss CMM (Coordinate Measuring Machine).
- Material traceability (FDA-approved silicone).
- Cleanroom assembly (Class 10,000).
- Biocompatibility testing (ISO 10993).
❓ What’s your lead time for custom LSR molds?
- Standard molds: 30 days (tooling + sampling).
- Complex molds: 45-60 days (multi-cavity, overmolding).
- Emergency orders: 15-20 days (premium pricing).
Note: LSR cures faster than plastics, so we can often reduce cycle times by 40%.
