Our Compression Set Button molds are built to produce the standard ASTM Compression Set Button per Method "B", Type 1. The molds are three plate type with overflows, hard chrome plated but not hinged and available in four and sixteen cavity configurations.

Spider Molds (Rubber Flow Evaluation)

Although there is not an ASTM specification for our "Spider" mold, the functionality of the mold will assist rubber compounders in the development of their recipes by allowing a practical study of the flow characteristics of various blends of ingredients. Two different half round cross sections are provided with measurement "whiskers" for flow evaluation. An additional section provides a sample for evaluation of the knitting characteristics of the stock. This sample can also be used for micro-indentor hardness testing as well as tensile testing of the knit portion. Our "Spider" molds are designed for use as a standard transfer mold with its integral pot, or an injection mold with the addition of the inject bushing provided. Five different sized sprue bushings are provided for the transfer option. All plates are hard chrome plated and hinged.
