We’ve seen a lot of new, custom cast requirements in recent weeks. These tend to be large or oversized parts where a standard, stock-sized piece of syntactic foam will not do the job. In most cases, these projects are the result of multiple discussions with customers on specific application requirements. While we have always offered this service, it has sometimes been unclear what options are available and what the limitations are. Now we are releasing new product data sheets (PDS) on custom cast work as well as new HTYAC LPX.
Custom cast items are quoted as rough castings and in most cases will require additional machining and finishing. Processors can also send molds to us. When we cast into aluminum molds, for example, the result will be a plug with a very smooth surface finish. HYTAC W, WF, WFT, FLX, FLXT and C1R can all be used.
HYTAC-LPX is a new epoxy syntactic plug assist material aimed at providing heavy gauge thermoformers with an economic solution that meets the demands of most large plug requirements. It is available as a solid syntactic or as a two-part system consisting of a core of epoxy coated large, hollow composite spheres and an exterior of high-performance syntactic foam.
If you’re looking at a large part or non-standard dimensions, give us a call or fill out our application assistance page. We’ll be happy to work with you and figure out the right approach.
