Overview

Die casting produces components that need minimal finishing compared with other casting techniques. However, some finishing will be required to ensure your parts perform flawlessly and efficiently.

Finishing is the final, critical stage in the production of your components. Finishing can improve the look of your product, ensure it performs efficiently, and prepare the items for any other processes required, such as painting.

At LEWIS Gravity Die Casting, we employ a range of finishing techniques to ensure your product is up to the job. Castings may require various levels of finishing depending on the end application.

There are many finishing techniques that can be used on your casting to produce the required result. These include linishing, fettling, polishing and inspection.

We have a wide range of finishing options available, so please call us to find out which would be the most suitable processes for your project.
