Electronics including housings and components for electronic equipment can be very intricate and specific which benefits the investment casting process and allows our team of experts to assist in the design prior to production and completion.

General engineering

Lestercast’s excellent reputation has been achieved through the entire process map from design assistance to manufacturing and finishing of bespoke industry-diverse products. The depth of experience in general engineering; a term used when the component produced doesn’t necessarily fit into a generic industry; allows the team at Lestercast to consistently advise on all aspects of the investment casting process.

Investment Casting Marine

The investment casting process is an excellent method for the production of high-corrosion resistant products due to the sub-sea nature of their final use. Lestercast is extremely well-versed in following design-specifications and process finishes to work into this sector.

Investment Casting Nuclear

Qualified as F4N (Fit for Nuclear), Lestercast are able to work directly into the nuclear industry to fit in with the stringent guidelines this sector demands.

Investment Casting – Oil and gas

A very prominent sector for Lestercast with the requirement for pumps, valves, sub-sea equipment to name but a few. Corrosion testing and surface finishes are highly specific needs in addition.

Investment Casting Rail

Railway castings are varied in final finished product and usage whether inside a train carriage or as part of signalling, hinges or brackets for example where the method of investment casting is ideal.

Safety & fire systems

Safety critical castings, as you can expect, are hugely quality-demanding and technically specific which is why Lestercast’s expertise is ideal to deliver your project to exact speciation.

Investment Castings – Valves & pumps

The manufacturing of bespoke pumps and valves via the investment casting process plays an indispensable role as it lends itself to the production of very complex shapes of pump and valve components.

We have considerable experience in producing components for an extensive range of sectors, but welcome the opportunity to assist clients in the development of products for new markets.
