Plastic Welding
Industrial-grade plastic welding for tanks, pipes, bunds, and structural assemblies.
Our plastic welding services cover the full range of industrial thermoplastic welding techniques including hot air welding, extrusion welding, butt fusion, and socket welding. We specialise in welding HDPE , Polypropylene , PVC , and PVDF for tanks, bunds, pipework, and structural assemblies.
P&M Plastics fabricates custom-welded components for water treatment facilities, chemical processing plants, mining operations, and agricultural applications.
Our welders are experienced in producing leak-proof seams and structurally sound joints that withstand chemical exposure, UV radiation, and mechanical stress. We fabricate custom tanks from 50 litres to 50,000+ litres, secondary containment bunds, fume hoods, scrubbers, and process vessels.
All welded assemblies can be pressure tested and certified to your requirements.
Our team can work from your drawings or develop fabrication solutions from scratch based on your project requirements.
