Thomco was founded in 1970 when the late Tom Cowan was contracted to manufacture and supply brass components for Afrox in 1970. The company started in a workshop in central Germiston, Gauteng. As the business expanded Thomco moved to a much bigger facility in Delville Business Park, Delville, Germiston where it is still situated today.
One of the main focuses throughout the history of the company has been to machine new and refurbish brass components and this still remains so to a certain extent today. The client base in the beginning revolved around the gas supply companies such as Afrox and the like, but this has diversified enormously since, as has the component and materials mix.
“We regard ourselves as both a jobbing and production shop. Machining components for the gas companies only makes up 30% of our mix. The next biggest percentage is in the security industry, which accounts for 20%.”
“We are machining 2 000 of the same component quite often but then we will do much smaller runs of larger components in iron, steel, plastic or aluminium.”
“With the mix of machines that we have we are quite versatile and flexible.”
Thomco purchased its first CNC machine in 2002 and it took another three years before the company purchased its second CNC.
“At the time it was a big decision in Tom’s life and the company’s history. The shop was used to running CAM type automatics, which we still make use of today for certain production runs. Even though they are older they still provide effectiveness with larger runs. Tolerances are kept closely as per specifications.”
“With the CNC we all had to learn but it is ‘no brainer’ today if you are a machining shop like ours and you don’t have some on your shopfloor.”
“It took three years before we purchased our second CNC – a lathe – and since then we have purchased at least one a year, with the latest one having only been installed in February. Altogether we now have four CNC lathes and two CNC milling machining centres and we are proud to say that even the first CNC machine that we purchased is still on the floor turning out quality components.”
“Our strategy in purchasing new, high-technology equipment is that it generally affords the shop higher quality, service, and training from suppliers, but also because we realise you achieve better performance and have lower maintenance requirements.”
“We also never wait until we get an order to buy machines with enhanced capability. We already have it and have developed it before we start exploring new opportunities. That’s a real advantage for us.”
The most recent machine purchased by Thomco is a Hurco VM10 vertical machining centre.
“It has a small footprint and large capacity for efficient machining and productivity. The 660 x 406 x 508 mm work envelope in a 1.8x1.7m working footprint and 10,000 rpm spindle as standard makes the VM10 very attractive for most applications.”
A little more conversation
“It is the second Hurco we have purchased. The defining feature of these machines is Hurco's WinMax CNC control. The straightforwardness of programming is just great and the control's ease of use as a conversational control, is another benefit. After installing the first VM10 the shop spent one day training on the machine and was running parts the next. In addition, we found the machine particularly suited to small and medium part runs, where programming flexibility is essential.”
The components which Thomco machine include adaptors and nipples, bull noses/inlet stems, Harris welding items, hose tails, manifold blocks, fittings, nuts and porta pack parts and components for regulators, torches and profile machines.
Services that the company offers include turning, milling and drilling of components. Materials machined by the company include brass, stainless steel (303, 304) steel (EN1A, EN9, K460, tool steel, EN19), plastic (PVC, nylon, bakerlite, vesconite) and aluminium. They also offer a finishing or coating service.
Currently Thomco has eight staff members.
