Our team

The people behind PVCWelder work with tarpaulin, banner and tent makers who need reliable welding, clean seams and steady support on site. Based in Germiston, Ekurhuleni, the team handles sales, installation, training, servicing and parts for customers across South Africa.

Parts and Support Lead

Mandla Mnisi keeps the workshop moving

Mandla Mnisi leads the business from Germiston and stays close to the practical side of the work. He spends his time on machine selection, site planning and the kind of fault finding that matters when a line is under pressure and a weld has to hold through heat, rain and handling.

He works with makers who run high-frequency and hot-air welding for PVC-coated fabrics, so he keeps the focus on seam quality, operator safety and service that makes sense for day-to-day production. Mandla also checks that the team stays aligned on installation standards, spare parts and the realities of working across Johannesburg, Durban, Cape Town, Pretoria and Bloemfontein.

Sales, parts and the right set-up

Alicia van der Merwe handles sales with a practical eye for what each workshop actually needs. She looks at the fabric types, seam widths, hems, keder profiles and eyelet work the customer is producing, then helps match the machine choice to the job rather than forcing one set-up for everything.

  • Machine installation planning
  • Parts supply for wear items and tooling
  • Service plans for busy production runs

She also works closely with the support side so that the right rollers, electrodes and alignment parts are available when a machine starts showing signs of wear. That keeps the buying process grounded in what will hold up in a real production bay.

Service work that stays close to the seam

Sibusiso Abrahams is the service technician who gets called when a weld is running uneven, a seal is lifting or a machine needs a proper check. He deals with preventive servicing, seam testing, tooling alignment and electrode refurbishment, with attention to the sort of detail that saves time later.

His work often includes checking temperature control on hot-air and hot-wedge units, cleaning feed paths and replacing rollers before they start marking the fabric. Coastal humidity in Durban and salt air near Cape Town can change how equipment behaves, so his servicing is shaped by real workshop conditions not just the manual.

Installation that sets the machine up properly

Johan Mkhabela handles installation and commissioning on customer sites. He makes sure the machine sits square, the tooling lines are correct and the operator starts with settings that suit the material thickness and the seam type being run.

He also handles site callouts when a machine needs to be checked after relocation or a production change. In many workshops, a small adjustment on pressure, guide position or feed alignment makes the difference between a tidy hem and a patchy result, so Johan keeps his work practical and measured.

  • Machine installation and commissioning
  • Tooling alignment and setup checks
  • Site callouts for moved or altered lines

Training that suits the operator in front of the machine

Thandi Mokoka leads operator training with an emphasis on safe handling and repeatable results. She shows teams how to work with RF welding for PVC-coated fabrics, where the seam needs a clean finish, and how to use hot-air and hot-wedge equipment for hems, keder insertion and eyelet preparation without damaging the sheet.

Her sessions are hands-on and usually shaped around the equipment already in the workshop. That includes basic start-up checks, recognising poor seam formation, cleaning tools after use and keeping hands clear of heated parts. The aim is not just to run a machine, but to run it properly under day to day pressure.

Spare parts and support that keep production steady

Lebo Motsepe looks after parts and support from Germiston, helping workshops get what they need without a long wait for the wrong item. He keeps track of consumables, replacement rollers, electrodes and other wear parts used in high-frequency and hot-air welding lines.

He also supports customers who are managing mixed work, from banner finishing to tarpaulin repairs and tent fabrication. That mix can place different demands on the machine, so Lebo helps identify the part that is actually wearing out, not just the symptom on the finished seam. The result is a more useful repair and less guesswork.

Questions we get asked

What kind of welding work does the team support?

The team supports radio frequency welding and hot-air or hot-wedge welding for PVC-coated fabrics, including seams, hems, keder work and eyelet preparation.

Can PVCWelder help with a machine already in a workshop?

Yes. The team handles installation, commissioning, fault finding, alignment checks, servicing and site callouts for machines already in use.

Which areas do you support from Germiston?

Support is provided across South Africa, including Johannesburg, Durban, Cape Town, Pretoria, Bloemfontein, Boksburg and Benoni.
