The Importance of Die Casting Finishes

Once a structural part has been die-cast, it’s important to note, the process is not necessarily over. In fact, there are a large number of die casting finishes for you to choose from  – all of which are intended to improve the aesthetic and functional characteristics of your component. These include everything from adding a decorative touch to the product to improving its chemical or corrosion resistance. They are not always essential, but in some cases, they are a crucial factor in the die casting process; a final step, ensuring that your product does exactly what it was intended to do.

Start with the Die Casting Finish

The process of die casting and subsequent die casting finishes have a symbiotic relationship; in other words, they are heavily dependent upon each other and they work together to create the final product. For example, a die casting which requires a particular decorative finish will need to be produced in such a way that design features – such as the parting line, gate, overflows, and vents – do not interfere with the intended look of the product. The cavity of the die-cast may also need to be altered somehow, thus ensuring that the die-cast surface is suitable for a particular type of finish.

Ultimately, each step of the die casting process has an impact on the final product and very slight details can determine whether or not a client’s exact specification is met. It is therefore incredibly important to discuss what you are expecting from the final product and which die casting finishes you think you will need. This needs to be done at the very start of the process, during the design stage, otherwise, there is potential for undesirable and unwanted results to occur.

A Range of Die Casting Finishes at Lupton & Place

It’s easy to see the importance of die casting finishes. First and foremost, they ensure that your final part matches exactly what you had in mind – completely fulfilling your requirements and meeting your component specification. Secondly, they can greatly improve the quality and value of your component or product, thus making it much more appealing to both you and your customers.

One of our main goals, here at Lupton & Place, is to make sure our clients are happy with their final die-cast. We want to make sure their part is totally compatible with its final usage; a die-cast that meets all the specified requirements and does what it was originally intended to do. Which is why, as part of our professional die casting service, we offer an extensive range of post-casting finishing procedures. Completed in-house, these die casting finishes combine our strong technical capability with an acute attention to detail and a rigorous design process and they currently include:

  1. Trimming

Whilst the metal is cooling, excess metal is accurately and effectively trimmed away from the final casting. This process allows us to create a sharply defined product to exact dimensions and the excess materials can later be recycled and reused throughout the die casting process.

  1. Vibratory Deburring

This is a well-known die casting finish, which relies on strong vibrations and friction to effectively smooth and deburr the die-cast. A specialised machine is used to press media against the die-cast component. Dependent upon which type of media is used, a different result is achieved.

  1. Shot Blasting

Shot blasting is a finishing procedure that is typically used to clean and prepare a die-cast for further treatments. Compared to other cleaning methods, it is significantly more effective, producing an exceptionally high-quality and uniform finish across the entire surface of the cast.

  1. Ball Burnishing

After die casting, a component can often have a very dull appearance. Ball burnishing is a type of die casting finish that effectively polishes the component. It is typically used with smaller parts (as an alternative to shot blasting) and it is a fantastic option if you would like to create a shiny surface.

  1. Surface Paints and Coatings

A coat of paint, powder paint or PTFE can be added to the surface of the die-cast, thus improving its overall aesthetics and perhaps personalising its appearance in line with your brand. Our die castings can also be successfully plated, and certain post-casting treatments can help create anti-corrosive and other useful properties.
