Sample database

This database demonstrates the great possibilities that a high quality PVC material and a high quality HF-welding machine give.

There are almost no limits to what you can make with high quality materials and high quality HF-welding machines.

Database with years’ of testwelding

Forsstrom High Frequency has during several years established a database with weld settings for PVC-materials. The suppliers of these materials are Serge Ferrari, Mehler Texnologies, Verseidag, Sioen, Rivertex and Dickson.

The database also displays how Forsstrom’s machines, accessories and software can be combined to manufacture different types of end products in the best possible way.

High quality HF-weld

Further, it shows the high quality of a seam welded with a Forsstrom machine. The seam is very strong, in most cases as strong as the surrounding, non-welded material. In some cases even stronger. To illustrate this we have tested the tensile strength of each welded material and compared the result with the tensile strength of the non-welded material. With a few exceptions, the non-welded material has broken before the welded seam.


All materials are welded with a Forsstrom machine equipped with the unique welding program EMP (Energy Monitoring Program). With EMP, the machine automatically sets parameters such as pressure, welding time and cooling time to values optimized for the material in question. For each sample we indicate guide values for the EMP settings that are suitable for that very material.

Our sample database

Our aim is that this database will give you a better understanding of what Forsstrom, Serge Ferrari, Mehler Texnologies, Verseidag, Sioen, Rivertex, Dickson Coatings and Dickson Constant can offer. We also want to show how we can help you become more efficient and accurate.
