Heat Stacking

Heat Staking is a joining technology to join two or more parts together where at least one is made out of plastic. The process is used to melt and deform the plastic material using heat and force at a set process time. De-forming the plastic is achieved by heating it above the glass transition temperature and apply pressure. After heating, the materials are cooled down under pressure again to below the glass transition temperature.
