PLASTIC MACHINING TOLERANCES


Understanding the relationship between plastic machined parts and what tolerances can be achieved during the machining process, is key to insuring your precision parts meet the quality and budget requirements. Selecting the type of plastic material for your application is crucial because there is multiple variables that can change a component such as moisture and temperature.

There are a vast array of choices in machinable plastics, such as Delrin®, PEEK®, Teflon®, Vespel® and Polycarbonate to name a few. Choosing the correct material is a key factor when holding a tight tolerance on your plastic part.

With over 39 years of experience machining plastic and various metal components, we are your trusted source.

Here are a few major elements that need to be considered when requiring tight tolerances on precision machined plastic parts.

  1. What material do you have planned to machine your part from?
  2. What features are you requiring tight tolerance on?
  3. What inspection methods will be used to check the tolerances?
  4. What environmental elements will you be checking the parts in?

When demanding tight tolerance machining, it’s crucial to understand each of these factors.  Working closely with your manufacturer reduces up front costs and helps prevent potential quality issues on the back end. Tamshell is a 20,000 sq. ft., temperature controlled facility that specializes in tight tolerance machining.

IN ORDER TO HOLD SUCH TIGHT TOLERANCES, WE PUT THE PARTS THROUGH THREE POINTS OF INSPECTION:

First article inspection

In-process inspection

___Final inspection

In addition to being a precision machining company, Tamshell is also a leading distributor of high performance plastics. See the list below for the type of high performance plastics we distribute, as well as some of their characteristics.
