Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...
1955: Weld-On developed the first clear, reactive acrylic adhesive that met U.S. Department of Defense military specification (MIL-SPEC) for use on aircraft canopies [1] 1958: IPS Corporation began endorsing the solvent welding technique, a type of plastic welding, and patented Weld-On solvent cement for use on plastic pipe and fittings.
Implant induction welding is a joining method used in plastic manufacturing. The welding process uses an induction coil to excite and heat electromagnetically susceptible material at the joint interface and melt the thermoplastic. The susceptible material can be contained in a gasket placed between the welding surface, or within the actual ...
Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to ...
Adhesive bonding is a joining technique used in the manufacture and repair of a wide range of products. Along with welding and soldering, adhesive bonding is one of the basic joining processes. In this technique, components are bonded together using adhesives. The broad range of types of adhesives available allows numerous materials to be ...

Hold time typically lasts for one half of weld time allowing the weld to solidify. The tooling is being removed from the part during a phase called “up-stroke.” This stage takes place at the completion of the hold time. [3] Some amount of plastic substrate can remain on tooling surface after the welding process.
The main obstacle to overcome in this process is the setting of the parameters. For example, if over-welding occurs, then the concentration of plastic in the weld zone may be too low and cause the seal to break. If it is under-welded, the seal is incomplete. [17] Variations in the thicknesses of materials can cause variations in weld quality.
