Hapco’s Hapflex™ and Hapcast™ are commonly used for making industrial fixtures. A fixture is a part-holding or support device used during assembly, painting, gluing, drilling, machining, bending, polishing, post-curing, etc. All fixtures are built to fit a particular part or shape and their purpose varies depending on the application. When used to retain a part’s shape at elevated temperatures, the fixture is often just a duplicate half of the original mold. In this case, a material with a higher service temperature, like Hapcast, should be used.
Many fixtures have a more open design, allowing access to the part while keeping it stable at the same time. The Hapflex™ 500 Series materials are flexible and grip very well, making them better suited to fixtures with few points of contact to a part. This series is also widely used for gaskets, non-slip coatings, grips, dampening pads for shock and vibration absorption, and other applications where flexibility and durability are required. The Hapflex™ 600 Series are semi-rigid, hybrid elastomers that can take a large amount of repeated abuse. This makes them a perfect choice for assembly fixtures, pulley wheel and roller coatings, stamping pads, covers, linings, and just about anything that takes a serious beating.
