Technical Support

01: Working Principle

Membrane Sealing High Frequency Curved Welding Machine works with thermoplastic membrane structure that has a high dielectric constant, in this welding process, an electric field is produced near the overlap, the positive and negative pole of which is alternated approximately twenty-seven million times per second, every time the electric field changes, the dipole molecules of the polymer attempt to align around to realign themselves to the new field orientation, because this movement of membrane molecules are impaired by inertia and friction, the molecules don’t flip in unison, this constant relative movement of the molecules results in intermolecular friction with results in inside heat and, subsequently, melting, high frequency/radio frequency membrane welding typically has weld cycle times from two to five seconds, and can handle the thickness of membrane sheet 1.5mm

02: Welding ranges

Some membrane structure plastic are more of a challenge to Membrane Sealing High Frequency Curved Welding Machine that others and may even require a special process, No matter the level of difficulty, KEEPLEADER Technologies is confined in its ability to expertly perform High frequency/HF/RF welding on the following thermoplastic membrane structure

021: Polyvinyl Chloride (PVC

022: Thermoplastic Polyurethanes (TPU)

023: Ethylene-vinyl acetate (EVA)

024: Nylons (Polyamide PA)

025: Some ABS Resins

026: Special grades of Polyolefins (PP,PE, PET)

03: Important Factors

The most important factors influence Membrane Sealing High Frequency Curved Welding Machine: #1: electrical power #2: pressure applied #3: welding time #4: cooling time, Finding the optimal process parameters will depends on your specific equipment, the materials involve and the specific geometries including thickness and area to be welded, achieving optimal results is often an experimental process guided by experience, as a guiding rule, the thicker material and focus on short welding times you need, the stronger electrical power you need
