Investment Casting Supplier UK
Precision Investment Casting & Lost Wax Casting Solutions
Trushape UK provides precision investment casting and lost wax casting solutions for manufacturers requiring complex, high-quality metal components. From our UK base, we work with a trusted global network of foundries and manufacturing partners to source investment cast components to suit a wide range of engineering applications.
Our investment casting sourcing service can support projects from initial component review and material selection through to casting, machining, finishing and supply. Investment casting is particularly suited to components requiring complex geometry, fine detail, dimensional accuracy and a high-quality surface finish across sectors including automotive, medical, marine, energy and general engineering.
Investment Casting Components and Capabilities
Investment casting enables complex metal components to be manufactured with excellent dimensional accuracy, fine detail and high-quality surface finishes.
Through our manufacturing partner network, Trushape UK can support investment casting projects involving a range of ferrous and non-ferrous materials, together with additional machining and finishing where required.
Our team can help assess the component, material, expected quantities, tolerances and finishing requirements before recommending an appropriate production route.
Understanding the Investment Casting Process
How the Investment Casting Process Works
The investment casting process begins with the creation of a detailed pattern, typically made from wax or a similar material. This pattern is an exact replica of the final product but includes allowances for thermal contraction
After the pattern is created, it is assembled with other wax components to construct a gate and runner metal delivery system. This assembly is often referred to as creating the ‘tree’
The entire wax tree is then dipped in a ceramic slurry followed by sand stucco. This process is repeated several times to build a thick ceramic shell around the wax assembly
Once the ceramic shell is dry and hard, the wax is melted out in a steam autoclave. Any remaining wax absorbed by the ceramic shell is burned out in a furnace, preparing the mold for the metal casting
The mold is preheated to a specific temperature and molten metal is poured into it, filling the cavity left by the wax
After the metal has cooled and solidified, the ceramic shell is broken away. The metal casting is then separated from the gate and runner system. Final post-processing such as sandblasting, grinding, and machining is performed to achieve the desired surface finish and dimensional accuracy
This process highlights the precision and efficiency of investment casting, making it ideal for producing complex shapes with high dimensional accuracy and excellent surface finish, while minimizing material waste and subsequent machining
Why choose investment casting?
Investment casting is particularly suitable where conventional manufacturing methods would struggle to produce complex geometry economically or consistently.
- complex shapes
- fine detail
- good surface finish
- dimensional accuracy
- reduced secondary machining
- broad material choice
- combining multiple features into one casting
