The PAS high tonnage, precision, true closed-loop heat staking machines is designed for production runs of medium to large sized parts. Heat staking and insertion makes use of direct contact heated tools and precisely controlled time, temperature, pressure and cooling, to reform plastic studs, walls, and protrusions, or to embed metal components into plastic. This offers the ability to perform multiple operations on several planes simultaneously. Cycle times are relatively fast, and productivity can be increased through the assembly of multiple products. Cosmetics are so exceptional that heat staking appears to be an extension of the molding process.
