Global manufacturers of high performance polyymers

Lost-Wax Casting

Makevale produces high quality XLPS (cross linked polystyrene) which are used as fillers by lost-wax casting suppliers to modify the viscosity and add strength to their precision investment casting waxes.

We collaborate closely with customers to tailor our polymers to meet their most demanding investment casting applications. Our lost-wax casting polymers deliver superior performance through control of the manufacturing process to produce consistent material batch after batch. We are the only company able to exercise control over the surface finish of the XL polystyrene bead and provide investment casting wax manufacturers with tight viscosity control.

Our lost-wax casting polymers achieve narrow particle size distributions, with nominal particles less than 100µm in size to ensure a good surface finish. They also have very low ash content to minimise the amount of undesirable material left behind in the ceramic shell after de-waxing, and a low residual content of styrene through our unique manufacturing processes. Our XLPS fillers are also thermally stable and density balanced to that of each molten base wax to minimise settlement.

Please contact our business development team if you’d like to find out more about our wide variety of acrylics suitable for lost-wax casting or receive detailed specification sheets or samples. Makevale’s track record in producing acrylics with unique investment casting properties means our R&D team will be happy to hear from you if you wish to develop a new acrylic suitable for lost wax casting waxes.
