    Forsstrom High Frequency

    The collaboration between FORSSTROM and TRAMO is based on quality, long-termism and trust

    Machine manufacturer Forsstrom High Frequency AB is based in Lysekil, from where the family business is run by the second and third generations of Forsström. All design, development, marketing and sales of the company's advanced welding machines, which their, largely international customers, use to manufacture e.g. high-quality truck and boat covers, tarpaulins and tents

    Forsstrom offers a wide range of machine models that enable high frequency welding in PVC and PU plastics. This process uses a high-frequency electromagnetic field (27.12 MHz) in combination with pressure applied to material surfaces, which softens them and allows them to join together. The process places very high demands on both the precision and quality of the components used in Forsstrom's machines, not least when it comes to adapting to electrical standards (voltage and frequency) that differ from country to country.

    Forsstrom came into contact with TRAMO ETV at an early stage and quickly realized that the company's transformers met the high quality and reliability requirements. This has resulted in a long-lasting cooperation where TRAMO ETV delivers several variants of customized transformers to Forsstrom, e.g. high voltage, isolation, SPAR (TGS) and incandescent transformers.

    We have a very good and long-term cooperation with TRAMO ETV. Their transformers create great value for us and our customers and are of high quality. In addition, TRAMO ETV always provides good service and excellent support.

    - Mariette Pettersson, Production Manager, Forsstrom High Frequency AB

    The cooperation has been strengthened over the years and Forsstrom especially values characteristics such as high product quality, service level and a generally good treatment. "We manufacture complex machines and have short lead times. That's why we need suppliers we can really trust. We have certainly found that in TRAMO ETV. They simply keep their promises," says Mariette Pettersson, Production Manager at Forsstrom High Frequency AB.
