High Frequency Fusing

In the fusing presses, heat has provided by electric heating elements. This limits the number of thicknesses of fabrics to be fused. If multiple layers of fabric and interlining could be stacked up and fused simultaneously, productivity might be increased by means of high frequency energy. The alternating waves from a high frequency generator are absorbed by the material, generating friction and heat between the molecules. Multiple plies of garment and interlining can be stacked up to 70mm high can be fused. Less pressure is required and the time required to generate heat depends on the capacity of the high frequency unit & the weight of the load to be fused.
