With feedback from load cells, encoders and other sensors, today’s microprocessor-controlled plastic welders offer extraordinary command over every aspect of the joining process. Depending on the machine, engineers can monitor and control ram force, ram speed, amplitude, power, energy, weld distance, weld time and hold time. These parameters can be measured individually or in combination to produce a good weld every cycle, regardless of the size, shape or composition of the parts.
Here’s a look at the latest technology for welding plastic parts.
Ultrasonic Welder Assembles Medium, Large Parts
The Standard 3000 pneumatic ultrasonic welder is suitable for assembling medium to large plastic parts. The 20-kilohertz welder can apply a maximum force of 3,000 newtons and has a maximum stroke of 100 millimeters. Stroke length can be set in 0.01-millimeter increments for precise welding applications. The machine can store 32 parameter sets. The machine can be used for welding, cutting and punching thermoplastic parts, nonwovens, textiles and films. It can also be used for embedding metal inserts in plastic. The machine can be housed in a noise-protection enclosure or integrated into automated assembly lines. A variant, the Standard 3000 CR, is certified for use in ISO class 6 clean rooms.
