Liquid silicone rubber (LSR) molds are essential for producing precision parts across industries—from medical devices to baby care products. The right mold design can significantly impact efficiency, material usage, and product consistency. Here’s a quick overview:
1. Glue Feeding Methods
- Solid-to-Liquid (Manual): Low cost and minimal waste, but limited precision. Ideal for simple molds.
- Solid-to-Liquid (Automatic): High precision, faster cycles—but more material waste. Best for complex molds requiring runners.
- Hot Runner: Simplified mold structure with no needle valve. Higher waste, commonly used for large products.
Cold Runner (Needle Valve vs. Open):
- Needle Valve: Precise control, minimal waste, higher upfront cost.
- Open (No Needle Valve): Lower mold cost, higher material waste. Suitable for prototyping or less tolerance-critical parts.
2. Molding Machine Types
- Standard Molding Machines: Cost-effective for basic LSR injection molding.
- Vertical & Horizontal LSR Machines: Designed for high-volume runs with improved process control and automation.
Why It Matters for B2B Buyers
- Cost Efficiency: Cold runner systems help reduce long-term material costs.
- Precision: Needle valve molds deliver reliable quality for tight-tolerance components.
- Flexibility: Open cold runner molds are ideal for quick prototyping and testing phases.
Choosing the right LSR mold depends on your production volume, part complexity, and cost budget. Need help optimizing your LSR project? —I’d be happy to discuss.Guangzhou Silicone Pro Co., Ltd
