The 4 Most Common Rubber Manufacturing Processes

Molding is comprised of three main manufacturing processes which are compression molding transfer molding and injection molding Compression molding is the oldest and least expensive method With compression molding a rubber compound is formed into a blank (chunk of rubber) the blank then gets placed into a mold cavity to be shaped
