Techniques How to do plastic welding
The great advantage presented by synthetic products is that they allow mass production, which, despite the constant increase in labor and related costs, leads to a lowering of the cost price of the number of products. In addition to all known and daily used objects, such as household articles, toys, pipes, “imitation” articles, many other products welding nozzles buffalo ny are currently made of synthetic materials at hugely reduced prices.
General categories of synthetic materials
Thermoplastics – PVC
Polyvinyl chlorides are generally composed of hydrogen and carbon, produced by the action of hydrochloric acid on acetylene.
They are dissolved by acetone, a product obtained by the distillation of wood, which is used, among other things, to make glues for welding photo and film films and recorder tapes. Unlike that of Polyethylene, the coefficient of expansion of thermoplastics is relatively low: 0.08 mm per degree and per meter.
Melting point oscillating between 250 and 400 °.
Its main uses are:
- The household items to use hot
- The flooring
- The wine racks
- The unbreakable records
- The shoes
- Certain building materials, etc.
Plastic ultrasonic welding: high reliability, extreme precision, and impressive repeatability
Ultrasonic welding welding nozzles buffalo ny allows fast and economical assembly of plastic materials, without adding material and without using adhesives. Commonly used in industry, it provides a solid and precise junction. Specialist in ultrasonic welding,
What is ultrasonic welding?
The term ultrasound designates mechanical vibrations comparable to those of musical instruments but with a frequency greater than the hearing capacity of the human ear (16 kHz).
Ultrasonic welding involves sending these high-frequency vibrations to two pieces of plastic using a metallic vi. The welding is carried out using the heat generated at the interface of the two parts. This heat is produced by the excitation of molecules caused by the emission of ultrasound.
Ultrasonic welding uses different elements:
- The ultrasonic generator
- The piezoelectric converter or transducer which will transform ultrasound into mechanical vibrations
- The booster or amplitude modifier which reduces or increases the amplitude produced by the converter
- The press whose role is to keep the elements to be welded under pressure
The pressure and the wavelength are studied according to the nature of each material to be welded. Once these parameters have been defined, the welding operation can then be carried out. which includes the following steps
Alignment of parts
- Ultrasonic emission heating the material to its melting point
- Pressure maintenance during the cooling phase
