Sprue, runner or gating waxes

We offers a tailored range of both virgin and reclaimed runner waxes to provide a clean and robust gating system for all scales of assembly requirements. These products are supplied under the Cerita®, KC™ and Paracast® brands.
Virgin runner waxes
For the most critical assemblies where thermal, mechanical and rheological requirements are the most demanding, virgin sprue waxes are the material of choice providing consistent injection, high strength and clean burnout.
When the product performance demands are high and the control requirements are at their greatest, Paramelt’s virgin runner waxes deliver. The industry’s most reliable and most commonly used virgin runner waxes are made by Paramelt.

With several options to choose from, we will work with you to find the most compatible runner wax for your process. To maximize consistency in your injection quality, our virgin sprue waxes are the best choice. They ensure low residual ash, consistent quality and repeatability while having the strength required to hold complex shapes.
Reclaim runner waxes
With state-of-the-art reclaiming facilities, we are able to offer consistent, high performance sprue waxes based either on a generic source or on your own autoclave wax stream.
The development of reclaim runner wax has benefited the investment casting industry tremendously. In addition to reducing the waste of disposing of spent wax, the reclaim runner waxes lower the cost to the foundry while delivering the needed performance.

We offer several reclaim runner waxes that cover a large majority of the application demands in the investment casting industry. More than simply needing a low melting point, runner wax needs mechanical strength to maintain proper spacing of the parts during shell building, to have low impact on the shell during dewax and minimal residual ash to prevent contamination of the metal during pouring.

A cost effective solution for the industry, reclaim runner waxes make good business sense to use whenever possible. With the industry leading technology of Paramelt, our reclaim runner waxes perform time and time again.
