HOW WE FINISH
Our customers regularly seek a complete end to end supplier for their products. Alliance Connect serves this customer need by providing a comprehensive list of secondary / finishing services.
Heat treatment is the process of heating and cooling metals to change their microstructure and to bring out the physical and mechanical characteristics that make metals more desirable or durable. The most common reasons metals undergo heat treatment are to improve their strength, hardness, toughness, ductility (stretchiness) and corrosion resistance.
When parts are created by casting metal, tiny defects are nearly impossible to avoid, these defect left untreated can impact performance under normal operation. Alliance Connect uses vacuum impregnation to introduce a sealing resin which seals the surface, reduces moisture and internal corrosion and improves the quality and integrity of the part.
Shot blasting is a finishing process that occurs post production to remove burrs (raised imperfections) giving a uniform finish. The process forcibly propels a stream of abrasive material against a surface under high pressure . Different material can be used depending on the finish required. Blasting is not only used for removing burrs, it can also be used to change the texture of a surface to increase adhesion or mechanical function or to providing a high quality cosmetic finish.
Sometimes cast parts can be used in the form they leave the mould. Often, they need to be machined to provide smoother surfaces or threaded holes or to remove the bits of metal not required. Alliance Connect machines all its own castings.
