Combining scientific engineering and experienced craftsmanship
for high quality investment casting

When it comes to making castings that require complex shapes and fine details, manufacturers often go for investment casting for a number of good reasons. Compared to other processes, investment casting may be more expensive and have a longer production cycle, but its tighter tolerances, smooth as-cast finish and freedom of design also give it an edge over other casting processes. This process is often used to make high strength parts that require immaculate quality and precision.

Investment casting is a labour and skill intensive process that involves many delicate steps (wax mold making, shell making, pouring, cooling etc.). The casting capabilities of different foundries may vary drastically, so it is always recommended to have professional casting engineers to review and QC check the production process.

Professional casting operation orchestrated by qualified engineers

Our engineering team utilizes the latest technology to help you design the best investment casting solution, and supervises the entire production process in our sub-contractor’s facilities. We can typically achieve a tolerance of ± 0.005 in (we can offer even tighter tolerance if necessary).

Combined strength of multiple foundries

We have been working with a number of highly experienced investment casing foundries to offer you more choice and flexibility. We offer different core types (such as waxless cores, soluble wax cores and urea wax cores) and specialized waxes (including low temperature wax, medium temperature wax and low temperature wax with polymer additives).

Full range of investment casting finishing services

We also offer a wide range of post-casting services, including machining (with CNC lathe or CNC milling), material testing (including tensile, hardness and elongation testing and more), pressure testing (we typically offer hydrostatic testing for hollow parts) and polymer impregnation (mainly for aluminum investment casting).

Freedom of design

The use of wax patterns and one-time ceramic molds give a lot of flexibility to the design of investment casting parts. Wax patterns are relatively easy to make, allowing finer details on the final product, and can be attached to a wax runner system to create a mold that can cast multiple parts at a time. The use of one-time ceramic shell molds (broken after use) may seem complicated at first glance, but this also enables the process to create intricate forms, make one-piece parts with undercuts, and eliminate parting lines and draft angles on castings.
