In one featured application, the company supplied to the manufacturer of a line of hose couplings for bulk material handling using stamped half-forms welded together. Ten different size configurations were being manufactured in aluminium, stainless and carbon steel. Due to wear, the customer needed to rebuild all ten dies at a substantial cost. Formitt Metal Labs was able to replace all forming and welding operations for the ten part configurations with one set of tube spinforming tooling. As a result, the quality and appearance of the parts was improved while the cost of future new dies, die repairs, and welding processes was eliminated. Formitt now provides spinformed production parts to the customer. A second featured application highlights a manufacturer of aftermarket motorcycle muffler shells. The old process stamped and welded end-cones to the muffler tube, ground down the weld and then polished the part. Formitt’s technicians developed a new manufacturing process that eliminated the dies, stamped parts and welded end- cones. The spinforming process improved the part quality by eliminating the welded joint and grinding operation, which enhanced part quality and provided a smooth finish ready for polishing. Formitt hollow tube fabricated assemblies may include the insertion of filtration elements, heat exchange components, and catalytic elements. The company’s hollow tube spinforming prototyping and production technologies are currently used in the automotive, HVAC, filtration, and marine industries, in addition to others.
