Our products

Product category: Hot-plate welding machines

Heat element welding

Suitable for almost all thermoplastic materials.

Method with two phase process sequence:

Phase 1: the plastification

Phase 2: the joining process

Absolutely reliable welding method for achieving high-strength welded joints.

No mechanical loading of the components.

Product category: Hot-plate welding machines

Electromagnetic resistance welding

Indirect plastification of the joining zone by electromagnetic heating of the metal components.

Reduction of stresses in the welded component by residual heat in the insert heating element.

No mechanical loading of the components or sensitive components inside the weld metal.

Suitable for welding plastic parts.

Optimal for the subsequent insertion of metallic components in thermoplastic parts, for extremely short.

Cycle times and unsurpassed insert accuracy.

Subsequent insertion of metallic components with sealing element without damaging them.

Product category: Hot-plate welding machines

Hot gas welding

Method specially developed for welding PA, PBT, PPO, POM and other thermal difficult to weld materials.

Particle free welding method for polyamide for achieving high-strength welded joints.

No oxidation in the weld seam area due to the use of inert gas.

No contact to the heating element.

No mechanical load of the join partners.

Suitable for all thermoplastics.

Example Applications:

steering oil tank, coolant compensating tank, pressure tank, guide rails, hydraulic oil tank

Product category: Heat impulse welding machines

Rotation friction welding

Special Features:

Generation of melting heat by friction

.Rotation symmetrical joining zone required.

Exact degree angle positioning can be realised.

Very economic on account of the short cycle times.

Suitable for all thermoplastic materials.

Applications:

spice jars, car fuel rails, oil mist separators, filter casings, fuel gravity valve, vacuum system reservoirs, connectors

More Less

Product category: Ultrasonic welding machines

Ultrasonic welding

Applications:

child toy`s, medical apparatus, household appliances, gift articles, packaging material, office organisation articles, bottle openers, tubes, ballpoint pens

Special Features:

The joining zones on top of each other of the plastic parts are vibrated by the effect of the ultrasonic sound, plastified by the generated adjacent surface friction and welded during the cooling time using the welding pressure.

Extremely short cycle times and thus very economic.

Low energy requirement.

Product category: Hot gas welding machines

Thermoforms

Applications:

mobile telephone casings, gas meter membranes, airbag baffle plates, razor components, vehicle circuitry elements, vehicle air guidance elements, car interior parts

Special Features:

Connection of components using a riveted joint.

Riveted joint is made using thermal deformation of a rivet dome.

High-strength joints.

Plastic/plastic and plastic/metal joints can be realised.

Joining of different plastics.

No mechanical loading of the components by the riveting process.

Can be used for all thermoplastic materials.

Product category: Infrared welding machines

Infrared light welding

Infrared light welding allows secure welding of all thermo plastic parts.

About us

Company details

KVT Bielefeld was established in 1981 and today we have gathered more than 31 years of experience in plastic welding technology.

We manufacture welding machines to join thermoplastic material and for thermoplastic-metal joining processes. Our customers include international companies that are active in all areas of the plastics-processing industry. In particular, in the automobile and vehicle industry as well as the area of household appliances, i.e. “white goods”.

Our long-standing clientele also includes manufacturers and suppliers of telecommunications and electric goods as well as the producers of medical technology.
