Press Moulding Machine Silicone Rubber for Badges & Lead Sinker
Equipment Composition The core equipment consists of a press moulding machine (vulcanizing press) and specialized high‑temperature silicone rubber.
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).
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
Applicable Products
Badges & Medals: accurately replicates fine patterns, lettering, and embossed details
Fishing Lead Sinkers: forms complex streamlined shapes with smooth surface finish
Applicable Alloy Materials Zamak, tin alloys, lead alloys, and other low‑melting‑point metals.
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
