Ultra-precision 20Khz Ultrasonic plastic welding machine for air/water filter welding

Parameter

Description

Ultrasonic plastic welding is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic components’ mating surfaces (joint area). This allows the plastic material to melt and forms a molecular bond between the parts.

Material Consideration
To bond two thermoplastic parts, it is necessary that the materials be chemically compatible. Otherwise, even though both materials may melt together, there will be no molecular bond.

A good example would be trying to weld polyethylene to polypropylene. Both of these semi-crystalline materials have a similar appearance and many common physical properties. However, they are not chemically compatible and are therefore unable to be welded to each other.

Like thermoplastics (i.e., materials with the same chemical properties) will weld to themselves. For example, one ABS part will weld to another ABS part.

Dissimilar thermoplastics may be compatible only if their melt temperatures are within 40ºF (6ºC) and they are of like molecular structure. For example, it is likely that an ABS part could be welded to an acrylic part because their chemical properties are compatible.

Generally speaking, only similar amorphous polymers have an excellent likelihood of being welded to each other. The chemical properties of any semi-crystalline material make each one only compatible with itself. When the materials to be welded are compatible, several other factors may affect the adhesive bonding of the parts. These factors include hygroscopicity, mold release agents, lubricants, plasticizers, fillers, flame retardants, regrind, pigments, and resin grades.
