In more than 25 years, Willems Industriële Producties B.V. has developed a particular specialism and expertise in the application of high frequency (HF) technique. This technique is used for welding various plastic products, or textile products which contain plastic.
Willems Industriële Producties B.V. delivers both new and used HF welding machines, overhauls your existing HF welding machines (retrofitting) and provides professional service and advice in the field of high frequency (HF) technique.
On this page you will find more information about the principle of HF welding technology, the benefits compared to other plastic welding techniques and the various applications.
You will also find extensive information on our delivery programme, about kinds of machines and their applications, about custom made machines, our stock of used machines, our service for all HF brand welding machines, our stock of spare parts, radiation measurements, our extensive facilities for your prototyping and pilot series, etc..
The principle of high frequency plastic welding is based on dielectric heating of the material to be welded.
The material to be welded is placed between 2 so-called electrodes, after which high frequency voltage is connected to the electrodes. The molecules in the materials to be welded are brought to vibration, which causes them to be heated, in order for the material to melt …
Advantages of high frequency welding technology to other joining processes: very even and very fast melting process, accurate control of the melting process (dosage, duration and position) possible.
Car upholstery, orthopaedic bandages, blister packaging, inflatables, tarpaulins, banners, tent canvasses, car mats, water beds, infusion and blood bags, rain gear, stationery items, tents, air filters, life jackets, blinds, etc.
We have a wide range of machine models, each designed for different types of products and production applications. Here you will find a various machine models with information about their application.
We have a large stock of used HF welding machines, which we can supply, professionally overhauled, with full warranty and according to all applicable EC and EMC guidelines. If desired, modified to your own requirements.
Development and manufacturing of customer-specific HF welding applications, for example from manual to fully automatic control, automatic product infeed/outfeed, fully automatic in-line production systems etc.
Development and manufacture of HF toolsets and welding electrodes, from a simple welding line, to complex 3D toolsets, whether or not in combination with cutting, punching, (pneumatic) clamping, positioning etc.
