Plastic Injection Moulding Finishes

Types of Plastic Injection Moulding Finishes

There are a variety of plastic injection moulding finishes that can be applied to a manufactured component. Often, no finish will be required at all. But, in certain circumstances, a plastic injection moulded part may require some type of finishing option before it is delivered to a customer. 

Here at RP Technologies, we provide several high-quality finishing options, all of which can enhance the standard of the component and help to give it many additional benefits. 

Some finishing options will improve the aesthetic appearance of a product. Other finishes will increase the strength of a plastic injection moulded component, making it more durable and robust. Other finishes can be employed to offer customisation and corporate branding.

Additional benefits of textured finishes include:

  • Plastic parts can be made easier to hold and grip
  • Provide ergonomic and functional improvements to the part
  • Hide parting lines

This article looks in detail at the various types of plastic injection moulding finishes which are available. It also examines the reasons why these finishes might be necessary, and it investigates how these plastic injection moulding finishes are achieved.

Our technical article, ‘Corporate Branding for Injection Moulded Parts,’ discusses the aesthetic and functional values of branding plastic parts with a company name, logo, or slogan. This article looks in detail at how this is achieved, examining the design considerations that must be factored into this process. It also explores the value – commercial and otherwise – of this type of finishing option, as well as considering the potential issue of this type of plastic injection moulding finish.
