The most important features of impulse sealing

Impulse sealing is a technique used to join thermoplastic materials such as films, laminates or coated fabrics. The process involves temporarily heating the material with an electrical impulse, which causes it to become plasticised and then hardens under pressure. Impulse sealing is characterised by speed, precision and energy efficiency.

Precision and process control

One of the key features of an impulse sealer is the ability to precisely control the process parameters. Temperature, pulse duration and pressure can be precisely adjusted to the type and thickness of the material. As a result, the method produces even and durable joints, which is particularly important for delicate films and multilayer materials. Process control minimises the risk of material damage, guaranteeing high-quality welding. Impulse sealers are available in the offer of the Zemat Technology Group.

Energy efficiency and performance

Impulse sealing is characterised by low energy consumption because the heating element is only active for a short pulse time. In contrast to other methods such as thermal welding, it does not require the heating elements to be constantly heated, which significantly reduces operating costs. The short work cycle and the possibility of quick cooling of the connection make impulse sealing efficient and allow for high productivity with low operating costs.

Versatility and variety of applications

Impulse sealing is suitable for a wide range of materials, such as polyethylene, polypropylene, PVC and multi-layer films. Impulse sealing is ideal for precise and aesthetic applications, such as sun shades, screens, awnings, pergolas and other shading systems made of technical materials. The versatility of impulse sealing allows for the effective joining of materials of different thicknesses and structures, making this technique a universal solution in many industries. Zemat Technology Group offers impulse sealers.

Aesthetic and durable joints

Joints made by impulse sealing are characterised by high aesthetics and durability. Thanks to precise control of the process parameters, the welds are even, tight and free of discolouration or deformation. The tightness of the welds is crucial in technical applications in which the materials must be resistant to humidity, dust or other external factors, such as in sun shades, screens or pergolas. The durability of the joints allows for their long-term use, even in difficult operating conditions.
