3 Critical Pain Points in Metal Part Packaging (And How LSR Molds Solve Them)
Metal part packaging demands precision, durability, and cost-efficiency—but traditional solutions often fall short. Here’s what’s holding back your production:
1. High Tooling Costs & Long Lead Times
Traditional metal packaging molds require expensive CNC machining and weeks of lead time. According to Grand View Research, the global injection molding market faces 5.0% CAGR growth, but LSR molds cut tooling costs by 40% due to simpler designs and faster curing cycles. Your competitors are already leveraging this.
2. Poor Resistance to Temperature & Chemicals
Standard plastic or rubber packaging degrades under heat, UV, or solvents. LSR (Liquid Silicone Rubber) offers:
- -40°C to 230°C operating range (vs. 80°C for TPU)
- Class VI biocompatibility (FDA/USP) for medical applications
- UL94 V-0 flame retardancy for electronics
The LSR market is projected to grow 6.5% annually—driven by demand for high-performance packaging in EVs and 5G devices.
3. Inconsistent Sealing & Waterproofing
Metal parts in new energy vehicles, wearables, and industrial equipment require IP67/IP68 waterproofing. Poorly designed molds lead to:
- Flash defects (excess material) → 15% rejection rates
- Air traps → Weak spots in seals
- Shrinkage → Loose fits over time
Yingtai’s AI-optimized mold flow analysis (per this arXiv study) reduces defects by 90%.
