CRS commenced operations in 1977 under the directorship of Gordon G.McCreedy, hereby referred to as GMC. It operated out of the premises of Nelson Motors in Berea Road, Durban, primarily carrying out metal stitching of cracks on castings in the automotive, non-automotive and various fields of industry. A family member assumed the position of the sleeping partner whilst GMC retained full management operation of CRS in Durban, due to GMC having been extensively trained in metal stitching and crack repairs by the family member in Johannesburg the previous nine months. CRS expanded quite rapidly and within six months, had a complement of approximately seven employees. However, with the phenomenal growth came the demand for specialized welding repair which CRS undertook. CRS out grew the premises by September 1980 with GMC and partner having to find alternate, larger business premises. The directors then purchased “Kingendo”, a property company formulated with the intention of providing adequate space for expansion of the business. After settling into the new premises, growth continued at a rapid pace, leading to the expansion into re-conditioning of cylinder heads. This resulted in a far more capital intensive operation. It proved successful and the directors further enlarged the premises by 700 sq. These enlargements allowed for the expansion into the automotive and general engineering markets in February 1983, incorporating re-boring, line boring and crankshaft grinding etc. This expansion phase into full engine re-coditioning and general engineering was the most expensive and resulted in a marked increase in overheads. Staff employment rose steadily over the expansion phases and had, by this time, peaked at about 32 full time employees. GMC still retained full management operation in Durban co-ordinating and controlling all sectors of administration, marketing and production. The increase in overheads and environmental factors affecting the economy led CRS maintaining only inflationary growth over the period February 1983 to March 1985, when the sleeping partner decided to dispose of his share of CRS to Greg Transell,hereby referred to as GTL. GTL, a former commercial aircraft pilot from Johannesburg relocated to Durban and immediately settled into becoming a hands-on working director like GMC. The shareholding remained evenly divided. CRS experienced a boom period from March 1987 with an above average capital intensive growth. This precipitated the purchase of additional machinery with a simultaneous increase in staff to utilize such machinery. The trend started to change towards November 1989 with CRS still growing, but at a slower rate, attributed by both directors to external factors prevailing in the economic climate at that time. This attribution is borne out by the fact that other firms in a similar industry were showing negative growth during that time period

During 1989 more capitals were invested in machinery to clear profit margins and update technology. Due to the diverse services that the company offers, CRS did not tend to feel the effects of economic recessions quite as badly as some other companies. The company has always been profitable and utilized these profits to plough back into the company in order to facilitate expansion and growth. This obviously had tax advantages as well. In January 1992 the company further diversified itself into the manufacturing sector. A range of automotive machines was developed by GMC and GTL intended initially for the local market. These products have been marketed under the name of M.D.M. This market has the potential to be expanded into supplying the rest of Africa and other foreign markets in the future. In January 1994 GMC purchased GTL’s 50% shares in CRS due to GTL immigrating to Australia. During the last 16 years CRS has maintained and re-conditioned all its machines and replaced all outdated machines and tooling with new technology. Employee and staff training has and will always be a high priority of CRS in its quest to deliver the best workmanship and service to its most valuable assets, its clients and associates. Our company is full members of the Retail Motor Industry, the Engine Remanufacturers Association of South Africa , Metal Industries Association and the Durban chamber of Commerce and Industry. FUTURE FORCAST GROWTH

It has been agreed by management and employees that the potential for the company to grow under the present product and service range is huge, and the company has spare capacity at every workstation thus not having to purchase any other capital equipment and tooling in order to grow the company in a normal nine hour shift. We also agree that should the need arise in the future, management will consider putting on a second shift to further increase customer satisfaction and machine utilization.

Cracked casting? Don't scrap it – stitch it. 🔩

This mine compressor housing came in cracked right through the body and bearing saddle. A new casting would have taken months, so we metal stitched it instead.

✅ Cold repair – no welding heat, no distortion
✅ Pressure-tight
✅ Back in service in days
✅ On-site repairs across KZN and nationwide

We stitch gearbox casings, engine blocks, cylinder heads, press frames, pulleys and more.

A cracked or leaking exhaust manifold gets treated as a nuisance job. We see the other end of it: cylinder heads arriving warped on the exhaust side (aluminium) or cracked (cast iron) — and on nine out of ten warped aluminium heads, the exhaust side is the worse side. The manifold is usually where it started.

New on the blog: what is actually happening, the damage pattern we see on the bench, why a bent head should never be skimmed on request, and the manifold that came in as two pieces and went back into service.

Cracked or broken exhaust manifold? Don't assume it's scrap.

This one arrived in two pieces. We welded it back together and machined the face flat so it seals correctly against the head — back in service with years of life left, at a fraction of the cost and wait of a replacement casting.

We repair cast iron manifolds, housings, blocks and heads for agricultural, industrial and marine machinery. Cleaned and inspected before we quote, so the price you get is the real price.

Send us a photo of the break and we'll tell you honestly whether it's worth repairing.

When a cracked casting stops production, replacement isn't your only option.

Metal stitching repairs cracked or broken cast iron and metal components — engine blocks, cylinder heads, machine bases, gearbox housings, large industrial castings — without welding and without the heat that warps and re-cracks.

At CRS Group we've been doing this in Durban since 1977. Here's why plants across mining, marine, energy and manufacturing choose it:

The benefits
🔧 No heat distortion — the casting keeps its original shape and tolerances
🔧 Faster back in service — often days, not the weeks a replacement part takes
🔧 A fraction of replacement cost, especially on obsolete or imported castings
🔧 Restores a pressure-tight, load-bearing seal
🔧 Done on-site or in our workshop — no fly-in specialist costs

FAQs

Is it as strong as the original?
Yes — a correctly stitched repair distributes stress across the crack and can match or exceed the original strength.

Will it hold under pressure and vibration?
It does. Metal stitching is used on running engines, compressors and pumps that operate under continuous load.

Can you repair a part that's no longer manufactured?
That's often exactly when it makes the most sense. If a replacement is obsolete or has a long lead time, stitching gets you running again.

How do I know if my part is a candidate?
Send us a photo of the crack. We'll tell you honestly whether stitching is the right call.

METAL STITCHING — COLD REPAIR OF CRACKED CAST IRON

That hole went straight through the block. No welding was used to close it.

Metal stitching is a cold mechanical repair for cast iron. Interlocking keys and pins are machined into the casting across the crack, drawing the fracture together and restoring strength without putting any heat into the component.

Why it matters on site:
• No new thermal stresses, no warpage, no embrittlement
• Safe where sparks or open flame are a hazard
• Often done in position — no stripping the machine down

We are based in Durban, not flown in. International stitching contractors bill travel, accommodation and standby time before any work starts. Being local to KZN removes that cost and shortens the time between your call and someone standing at the machine.

Engine blocks, machine beds, pump and compressor casings, gearbox housings, crusher frames, marine castings — and obsolete parts where no replacement exists.

Send us photos of the crack with rough dimensions. We will tell you honestly whether stitching is the right process, and come back with a price and a realistic turnaround.
