StockCap's compression molding operations are located across the globe and are utilized to make not only our extensive line of masking plugs and caps, but also custom molded products. Here are some examples of our capabilities.
Solid Rubber Parts
The compression molding process is ideal for manufacturing all types of solid rubber plugs and rubber stoppers. While the process is not as great as injection molding for creating caps or covers with small details or severely slanted angles, it can still produce fairly complex parts.
Rubber plugs also work extremely well with applications involving copper tubing.
High-Temp & Chemical Resistant Parts
While flexible, dip molded materials can be formulated to withstand some heat and chemicals, many protective caps, plugs and covers requiring high-temperature or chemical resistance will specify silicone or EPDM materials that are typically produced using the compression molding process.
Cushioned & Resilient Parts
Rubber's natural resilience makes it (and the compression molding process) the ideal material for protective parts that need to provide cushion or return to their original shape after being stressed.
StockCap's line of rubber seal plugs, for example, are made from a rubber material that self seals after nitrogen is injected through the center of the plug using a needle.
A Case in Point
When our large truck axle client was looking for protective paint masks that could be used multiple times, our team developed these custom, compression molded covers made from a high-temperature resistant, yellow silicone material.
