TM20/TM25/TM30   

TM 20, TM 25 - TM30 Hydraulic Bridge Press + Powered Loading Trays
The RELCO TM20 is a highly compact HF welding machine which is suitable for a wide range of applications in the automobile industry, inflatables, medical mattresses, nursery furnishings and extra large sample swatches etc. The hydraulic press enables the fast action and high pressures required for difficult materials and lay-ups. The construction is adaptable for other applications e.h. Increased daylight to 610mm (24") for automobile carpets. The electronic circuitry incorporates the very latest technology to achieve maximum efficiency from the H.F. Output which, combined with the mechanical features, enables optimum productivity.
