Investment Casting Plugs
IPS Ceramics is proud to supply Ceramic Casting Plugs in a range of sizes, shapes and materials. They add to our growing portfolio of products for foundry, casting and heat treatment.
These ceramic plugs are used for Investment Casting (also known as the “lost wax” or “precision casting” process). This casting offers excellent tolerances and surface finish, and is ideal for complex geometries. Used across the advanced engineering scene, it’s vital to the aerospace, defence, power generation, automotive, oil and gas, medical/orthopaedics and jewellery industries. Our Casting Plugs cover pattern assembly vent holes and work as a mechanical means of closing core supports within the ceramic shell.
Because Investment Casting / Lost Wax / Precision Casting uses high pressures and temperatures, our plugs are volume stable and temperature resistant. Because they are single-use products, they also combine this stability with competitive costs, hence their already proven popularity in the aerospace, gas turbine, steel alloy, and precision casting industries.

The casting plugs are available in wide range of different grades and materials. If you need a smooth and clean finish, 95% to 99% alumina material is available. If it isn’t needed, we can offer you a corundum/mullite mix. Need a bespoke product? Our team can design and prototype a variety of components for you. No matter what, IPS Ceramics has the skills and the expertise to help your process.
