Plastics can be joined or connected to other materials in many different ways. Riveting, for example, does not use any heat so there is no change in the material structure or strength. Similarly, adhesive bonds – which are considered elastic and inexpensive – do not subject the materials to be joined to high temperatures. Heat-based welding, on the other hand, requires little processing time and few process steps.
We can recommend various welding techniques for plastics depending on the malleability. Thermal contact welding with heat and pressure is suitable for all dimensionally stable thermoplastics. High-frequency welding by means of electromagnetic machining works on plastic materials with dipoles. Ultrasonic welding by means of ultrasonic waves can, on the other hand, join all thermoplastic materials. We are glad to consult you.
Key factors for selecting an adhesive method include the size of adhesive surfaces, water resistance, initial strength and heat resistance. A distinction must also be made between thermoset plastics and thermoplastic materials, because special adhesive properties are to be expected for each plastic group. As a proven specialist for plastics processing, we will work with you to find the best method for your products and/or desired result.
Riveted joints are used for flat material parts such as sheet metal, plastic parts, leather or robust cotton fabrics. Rivets are generally made of metal and alloys, but plastic is also a possibility. Conventional riveting processes include solid riveting, pop riveting and self-piercing riveting. You can rest assured that we always use the process that best fits to your product and its application!
