Makevale produces high-quality cross-linked polystyrene (XLPS) that 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.

Makevale’s 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 XLPS bead and provide investment casting wax manufacturers with tight viscosity control.
The 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.
