Consistantly implemented plastics expertise: Hot-gas welding. Progress for your success – Pöppelmann K-TECH∏.

Particle-free and high-strength welding seam joints – plastic technology without compromise.

Oil suction pipe with washer. It would be impossible to produce this item using compact injection moulding. As a 2-part, cleanly welded component it offers an effective and economical alternative. Besides this, a metal sleeve and a washer are integrated reliably as early as during injection moulding.

Oil displacer. When used in series, this complex plastic component is fully immersed in oil inside the engine. Compulsory: a high-tensile welding seam meeting the highest demands on cleanliness. The Pöppelmann solution: The welding seam is used to guide the outer weld flash into the component.

Examples of particle-free and high-tensile welding seam joints

This avoids thermal damage to the plastic. Besides the cleanliness, this method has the additional benefit of producing high-strength welded joints. Another plus: The hot-gas welding method can be used for a large variety of technical materials.

This method is particularly suitable for media-bearing (air, oil or water) plastic components. The hot-gas welding method is the only way to accomplish a high-strength, homogeneous and particle-free thermal welding on a large variety of high-quality thermoplastics. This produces excellent results, especially during welding of polyamides.

Advantages of hot-gas welding: Particle-free, thermal welding of plastic parts. No oxidation in the area around the welding seam. High-tensile welded joints. Can be used for a large variety of technical materials. No mechanical stress on the processed pieces. Touch-free, thermal heating of the joint zone.

Nowadays, technical plastic parts have to meet a lot of complicated requirements. Besides the design challenges, increasing cleanliness requirements for media-carrying components are a particularly important task. For this reason, Pöppelmann K-TECH∏ manufactures these components using the hot-gas welding method. The process has special advantages: In contrast to mechanical welding, this thermal welding method is particle free. The use of inert gas in the area of the welding seam avoids oxidation of the material.

Significantly reduced design times: One-stop component design and series production.

Success in series: Pöppelmann K-TECH∏ has extensive experience in handling a variety of materials and tool requirements.

Support right from the start: As early as in the design phase, important structural features are analysed, including the geometry of the welding seams, to reduce tool costs.

Improved welding seam geometries: for example, building shadow gaps directly into the component to cover the welding seam.

Fully furnished plant: Due to the existing series applications, the required periphery is already in place.

Process reliability: Pöppelmann K-TECH∏ is in control of the steps required across all project stages – from design to production.
