Press Moulding Machine Silicone Rubber for Badges & Lead Sinker

Press Moulding Machine Silicone Rubber for Badges & Lead Sinker

1. Equipment Composition
   The core equipment consists of a press moulding machine (vulcanizing press) and specialized high‑temperature silicone rubber.

2. Working Principle
   The press moulding machine vulcanizes the silicone rubber into a precision elastic mold under high temperature (50–300℃) and high pressure (max. 50T).

3. Key Properties of Silicone Rubber

   • Heat resistance up to 500℃, capable of withstanding molten alloy pouring temperatures

   • Low shrinkage, ensuring dimensional accuracy

   • Excellent elasticity for complete filling and easy demolding

   • High tear strength, extending mold service life

4. Applicable Products

   • Badges & Medals: accurately replicates fine patterns, lettering, and embossed details

   • Fishing Lead Sinkers: forms complex streamlined shapes with smooth surface finish

5. Applicable Alloy Materials
   Zamak, tin alloys, lead alloys, and other low‑melting‑point metals.

6. Process Advantages

   • Significantly lower tooling cost compared to metal molds

   • Short production cycle, enabling quick order response

   • Flexible changeover, ideal for small‑batch and diversified production

   • High precision of finished parts, reducing the need for extensive post‑processing
