Plastic is undeniably one of the most used elements. Its applications are widespread. From tiny pins to automobiles, the applications vary extensively. From basics to luxuries, plastic has unlimited usage. Considering its application in different spheres, the role of plastic welding has become even more intense. 

A quick insight 

Although relatively new, plastic welding is a widely accepted concept. Plastic welding is especially important to the automobile and the electronic packaging industries. The process which helps create molecular bond among two well-matched thermoplastics offers superior strength to objects. There are three primary stages of plastic welding which include pressing and heating followed by cooling. However care should be taken when pressure is applied during the welding process to ensure proper orientation. 

Methods of plastic welding 

The commonly used methods of plastic welding have been mentioned below: 

Laser welding: The process involves usage of advanced technology in order to repair crack. During the process several plastic pieces are clasped together while a beam of laser is allowed to pass through them. As a result when heat is applied along the cracked line, the pieces join back to normal. This speedy process gives the best of results. 

High-frequency welding: Polyurethane and PVC are welded with the help of high frequency welding techniques which use electromagnetic waves on chemicals containing electrons. 

Hot Glass welding: The procedure more commonly involves the use of heat guns for softening plastic pieces so that they can further be joined using the filler rod. Hot glass welding process is more or less like bead sealing entailing the application of heat to establish bond between several plastic pieces. 

Solvent welding:   This is a common practice applied by welders. The approach of Plastic Welding Gold Coast involves softening of plastic pieces with two primary solvents: 

  • Dichloromethane 
  • Tetrahydrofuran 

The main aim is to ensure that a bond is created between the polymer chains. The method is mainly applicable for production of PVC pipes which are widely used in households. During solvent welding, a weld forms as the solvent disappears; thus joining pieces of plastic together. 

Extruded bead sealing: This is yet another common practice used in welding of plastics. It entails use of a hot bead between two separate sections followed by which the latter is pressed together by means of a manual extruder along with the welding rod. The welding method may also involve heating and pressing of separate parts together. 

Induction welding: Induction welding demands usage of conductive metal which is positioned right between plastic pieces which need to be joined. The metal placed in between is heated by means of frequency generator and as the pieces soften up they are merged to form a single object. 

Considering that plastic is used for various purposes, it has become a vital element which finds its applications in different industries. Also, the composition of plastic makes it softer and malleable. Regular wear and tear can cause plastic to break or crack. Materials made of plastic have limited resistance against pressure; hence they need to be handled with care. Plastic pieces which easily get broken or cracked can be welded using various methods.
