Hot Gas Welding

Our patented procedure for particle-free and oxidation-free welding. Hot Gas Welding is the patented procedure for particulate-free welding of high-performance plastics. Well suited to join all types of thermoplastic molded parts. Outstanding results are achieved in the thermal welding of polyamide and other high-tech materials. Hot Gas Welding process can easily weld plastics that are considered to be too difficult to weld, including PBT, POM, PPO, and PPS. This innovative procedure is used mainly when it is important to make high-strength welding connections without micro-particles arising during the welding process, as is the case in mechanical welding procedures. This also applies to weld connections for which thermal degradation, or damage to the material for the weld connection, is unacceptable. Therefore, for many high-quality thermoplastics, hot-gas welding is the only way to get a high-strength, homogeneous and particle-free thermal weld.

Superior Aesthetics and Clean Welds with Particulate-Free Welding
Nitrogen gas flows through custom-built heater manifolds and is delivered to the weld seam via a custom-built needle or nozzle profiles. This is accomplished without contacting the parts. The absence of friction to heat the weld area results in a particulate-free welding solution

Easily Welds Complex 3D Parts
Welds complex 3D shapes by using heated nitrogen flowing through custom-built nozzles of different heights

Strong Hermetic Seals
Stronger welds and no ash in the welding seam because of no oxidation in welding seam by using inert nitrogen gas.

Non Contact Welding Process
No mechanical stress on the plastic part and no pollution on the heating element with non-contact welding.

Accurate & Repeatable
Repeatability of weld depths with an accuracy of less or equal to 1/10mm (injection part quality assumed).

Joins a Wide Range of Thermoplastic
Joins all types of thermoplastics, including glass-filled materials. Plastics that are considered to be too difficult to weld, including polybutylene terephthalate, polyoxymethylene, polyphenylene oxide, and polyphenylene sulfide.
