Considerations in Extrusion Tolerances

When it is time for you to start your next plastic extrusion project, you might immediately be thinking about the design or the materials. While those things are important, it is also critical that you choose the options that will help you get as close to your tolerances as possible. Here are a few things to keep in mind when thinking about tolerances in plastic extrusions:

  • What does tolerance mean? A tolerance is the variance from the ideal design parameters in a project. The word is used in many industries and the measurement of a tolerance can vary depending on the product and the way that it is used. Tolerances can be measured by size, pressure, thickness, color and even overall dimensions.
  • Tolerance determines cost. While you can certainly eliminate most tolerances if you use a precise enough process, to do so may mean an extraordinary cost and processing time. That is the reason for a tolerance. A tolerance gives you the closest option to the ideal without sacrificing quality or performance. Trying to make each part perfect may price you out of the market.
  • Tolerance can be affected by the process used. In the extrusion industry, there are many processes that are available. The results that you get may be due to the equipment used or even the type of plastic chosen for the project. In addition, tolerances can be affected by the amount of details that a part has and how complex it is to manufacture.
  • Tolerances are usually the best when cooling is part of the process. When quick cooling is part of the extrusion process, the tolerances can be met easier. Materials that hold heat can move out of the required measurement zones, so look for processes that include cooling. You can be sure that you will get closer to your specifications.
