Investment Casting is also known as Lost Wax Casting is generally used for small castings are made from almost any metal, especially stainless steel. This process generally more expensive per unit than die casting or sand casting but with lower tooling cost. It can produce complicated shapes that would be difficult or impossible by normal manufacturing techniques. Parts made with investment castings often do not require any further machining, because of the close tolerances that can be achieved. X-PRO is a precision steel investment casting company providing investment casting products and other casting services. Contact us today for your precision investment casting product’s needs.

Sodium Silicate Investment Casting

1. The coasting bond brushed on the pattern surface is water glass in this process.
2. Compared with the sand castings, parts made with lost wax casting(water glass) have better surface quality (surface roughness to 12.5 microns) and higher dimensional accuracy.

Silica Sol Investment Casting

1.The coasting bond brushed on the pattern surface is silica sol in this process.
2.Parts made with lost wax casting(silica sol) have the tolerances are 0.1 mm for the first 25 mm (0.005 in for the first inch) and 0.02 mm for the each additional centimeter (0.002 in for each additional inch).
3.A standard surface finish is 1.3 – 4 microns (50 –125 μm). Compared with the water glass process, parts made with lost wax casting(silica sol) have excellent surface finish and higher dimensional accuracy.

The Process of Investment Casting

Main Steps:

1.Produce a master pattern

2.Create a mold

3.Produce wax patterns

4.Assemble wax patterns

5.Apply investment materials

FAQ for your new project

Why X-Pro?

We connect you with the best designers in the business, and we offer the most comprehensive set of services for inventors you’ll find anywhere. We take the guesswork out of online design services, and let you focus on what’s important.

How do private projects work?

Simple. Just send us a project brief and we will provide you with a design quote from a pre-qualified designer for your project.

Who can see my project?

Private projects are entirely confidential. Only you and the designer that you will be working with will see your project description, file attachments and submitted work.

Do I own the designs & IP?

Yes. Our legally binding terms of service assign the ownership of intellectual property (IP) from the designer to the service buyer for any paid designs.

Do you offer manufacturing services?

Yes we do! We offer a range of  manufacturing services, including 3D printing, rapid manufacturing and conventional injection molding.

How is a design project different from hourly services?

Design projects are limited-term projects with a concrete budget, based on an upfront quote from the CAD designer. Hourly services are for ongoing work that generally have an open work scope.

Will designers sign a NDA?

We’ve got this covered. Our legally binding terms of service covers freelancer non-disclosure. Freelancers on X-Pro have agreed to and are bound by the terms of non-disclosure that are outlined in our terms of service.
