Designing a reliable threaded connection in a plastic component is often a key challenge for engineers and manufacturers. Plastics offer significant advantages in terms of weight reduction, design flexibility and production efficiency, but the material itself may not always provide the durability required for a long-lasting screw connection.
When a plastic component needs to be assembled, serviced or adjusted repeatedly, a direct thread in the material can lose performance over time. Wear, reduced tightening force and damage to the plastic structure are some of the common issues that can affect the reliability of the final assembly.
Brass threaded inserts for plastic components provide an effective way to overcome these limitations by creating a strong metal thread within the part. This solution improves fastening reliability, allows repeated assembly operations and helps maintain consistent mechanical performance throughout the component’s lifetime.
The selection of the right insert depends on several technical aspects, including the type of polymer, component design, production method and expected operating conditions. A correct evaluation helps avoid unnecessary oversizing, assembly issues and premature failures.
Different applications require different insertion technologies. Heat-set inserts are commonly selected for thermoplastic components where high pull-out resistance is required. Press-in inserts offer a practical solution for quick installation, while mould-in inserts are integrated during the manufacturing process when maximum retention within the plastic part is needed. For applications requiring a reinforced internal thread without mould modification, ENSAT self-tapping threaded bushes represent a reliable alternative.
A.T.S. helps companies and technical departments identify the most suitable fastening solution by providing technical support and access to a wide range of brass threaded inserts for plastic applications from specialised manufacturers.
From automotive and electronics to industrial equipment, automation systems and consumer products, these fastening solutions are used wherever plastic components require a durable, precise and reliable threaded connection.
