Because of its unique combination of lightness and flexibility, nowadays plastic has replaced metal in many applications.
It is a versatile, cost-effective material that offers endless opportunities for innovation.
Plastic materials are used virtually everywhere, from transportation to electronics, from industrial machinery to construction, and in countless other industries. The car we drive, the computer we work with, the pipes that bring water and gas into our homes… All of these things depend on plastic components that need to be assembled and fastened properly for our safety, comfort, and efficiency.
The particular characteristics of plastics require specific fastening systems, which must be considered during the design phase.
When we talk about plastics, we actually refer to thousands of different polymers available on the market. A first distinction to make is between thermoplastics and thermosetting materials:
We can say that there are no universal guidelines for fixing plastic materials: each situation is unique and must be carefully studied to identify the most suitable fasteners for a given project.
The performance of fasteners on plastics is affected by several factors, such as:
Characteristics such as ductility, thermal expansion, or retention strength change from one type of plastic to another. This is why laboratory testing is often the only way to determine the performance of a fastener. Our field application engineers can accompany customers through every step of the production process, from selecting the best fasteners to designing a customized solution.
Standard fasteners can often cause problems when working with plastics, which is why Specialinsert® has designed highly innovative solutions. Bushes, nuts, quick fasteners, threaded, press-fit, or heat-set inserts: our range of fasteners for plastic materials can meet any requirement.
