LSR Injection Формовка Превосходство
Precision liquid silicone rubber injection molding with 24 advanced production lines delivering superior quality, consistency, and efficiency for demanding applications.
The LSR Injection Molding Process
Our advanced liquid silicone rubber injection molding process combines precision engineering with automated quality control for consistent, high-performance results.
Material Preparation
FDA-grade LSR materials are precisely measured and mixed in automated dosing systems ensuring consistent A/B ratio accuracy within ±1%.
Precision Injection
High-pressure injection into heated molds (150-200°C) with servo-controlled systems maintaining shot-to-shot repeatability of ±0.1g.
Rapid Vulcanization
Platinum-catalyzed curing in precision-temperature controlled molds achieves complete cross-linking in 30-90 seconds.
Automated Demolding
Robotic demolding systems with integrated vision inspection ensure zero-defect part removal and immediate quality verification.
Post-Cure & Inspection
Secondary thermal treatment and comprehensive dimensional inspection using German Zeiss CMM systems validate final specifications.
Why Choose LSR Injection Molding
Superior material properties and manufacturing efficiency make LSR injection molding the optimal choice for demanding applications.
Exceptional Purity
Platinum-cured LSR eliminates peroxide residues, achieving 99.9% USP Class VI biocompatibility for medical and food-contact applications.
Extreme Temperature Stability
Continuous operation from -60°C to +250°C with minimal property degradation, ideal for automotive and industrial applications.
Superior Dimensional Accuracy
Low viscosity flow and minimal shrinkage (0.2-0.3%) enable complex geometries with ±0.05mm tolerance consistency.
Rapid Cycle Times
30-90 second cure cycles compared to 3-10 minutes for HTV compression molding, maximizing production efficiency and throughput.
Multi-Material Capability
Two-shot and over-molding processes enable LSR bonding with thermoplastics, metals, and other substrates in single operations.
Cost-Effective Scalability
Minimal material waste (95%+ yield), reduced labor requirements, and automated production enable competitive pricing at volume.
LSR vs Traditional Molding Methods
Comprehensive performance comparison demonstrating LSR injection molding advantages across critical manufacturing parameters.
| Parameter | LSR Injection | HTV Compression | Thermoplastic Injection |
|---|---|---|---|
| Cycle Time | 30-90 seconds | 3-10 minutes | 15-60 seconds |
| Диапазон температур | -60°C to +250°C | -40°C to +200°C | -20°C to +80°C |
| Допуск на размеры | ±0,05 мм | ±0.15mm | ±0.08mm |
| Material Waste | <5% | 15-25% | 3-8% |
| Biocompatibility | USP Класс VI | USP Class VI* | Limited |
| Automation Level | Fully Automated | Semi-Automated | Fully Automated |
*Note: HTV silicone can achieve USP Class VI certification but requires additional post-cure processing and extended cycle times for peroxide removal.
