plastic fabrication - creating a display case for collectibles

Are you looking for a creative and unique way to display a collection or two in your home? One great way to get custom displays for your collections is by working with a plastic fabricator. Having custom displays made ensures that your collection is displayed in the exact manner that you want it to be. You can have open shelving made, or fully enclosed cases to protect the collection from dust. My site includes several examples of displays that I have had made or have seen made by a plastic fabricator. Hopefully, you can gain the inspiration to design the perfect display for your collection.

Options Available When Performing Tensile Tests

Ida Beck

Advanced plastics are an important part of processing and manufacturing. For that reason, it's important to use plastic film testing methods that are reliable. One of the most important parts of plastic film testing is a tensile test.

The Importance of Tensile Tests

Tensile tests are designed to test the tensile strength of plastic. Tensile strength determines how much pulling force a plastic film can be subjected to before the film breaks. If the plastic does not have the appropriate tensile strength for an application, it can be pulled apart. 

Types of Tensile Tests

Various tools exist for this purpose, including manual tools, hydraulic tools, pneumatic tools, and self-tightening tools. Self-tightening tools are able to test the plastic without the need for manual input. In contrast, with a manual tool, you may need to use elbow grease to test the plastic.

Hydraulic tools rely on the power of fluids, and pneumatic tools rely on compressed air. Pneumatic systems are sometimes preferred because they are very clean and you don't have to worry about leaking hydraulic fluids, but hydraulic systems can be more powerful and precise.

Testing Tensile-Related Creep

Several tests are designed to only test the tensile properties of plastics, but other tests also consider adjacent concerns. There are several other tests that test the compressive and flexural creep of plastics. When some materials are placed under stress over a long period, they can begin to deform permanently.

Plastics vulnerable to this problem may lead to parts that eventually become defective. Creep recovery might also need to be tested. As the tensile stress is removed, the plastic may return to its original shape. However, it's important to test to what extent it will recover. 

Testing Fracture Strain

Some plastics also need to test the elongation at break, also referred to as fracture strain. This is described as a ratio between the initial length and the length that the material exists at the break. In other words, it describes how much a plastic can stretch before it breaks.

Choosing the Right Test for Your Plastic

Some tests are designed to check specific types of plastics, such as extruding and molding plastics. Others test thin sheets or reinforced thermosetting plastic. But regardless of what type of plastic you're working with, it's important to test the tensile strength to know if a plastic film will be suitable for your application and that your product will not be defective.
