Sunnyrock yard: clean seats and a tag on every liner
How we stopped yard rust from hiding heat numbers and bolt seats, with a handheld laser cleaner and a fibre laser marker from AM.CO.ZA.
Rust on the rack, guesswork on site
Manganese does not mind the weather. Plant leads do. A jaw plate set or a cone mantle liner that has stood on our Highveld racks through a wet summer comes off the pallet with orange bloom over the cast-in heat number and over the seating faces. On site that means somebody wire-brushing a bolt seat at 2am before a liner change, or a call to us asking which casting batch the part came from.
Thandeka Sigcau, who leads our wear notes, had seen it in too many change-out photos.
“A dirty seat can’t be checked, and an unreadable number turns the wear log into guesswork. We wanted both sorted before the part leaves our gate, not on the night of the change.”Thandeka Sigcau, Wear Notes Lead
Two machines between the racks and the dispatch bay
We tried grit blasting and we tried better wire wheels. Blasting left media all over the yard, and wire wheels were slow and hard on the people holding them. So we went to AM.CO.ZA, whose Johannesburg branch is a short drive from Sunnyrock, and put two laser machines on the floor.
- Handheld laser cleanerOut of their laser cleaner range we took the LM-CLEAN-2000. It lifts surface rust off seating faces, lifting lugs and the patch around the heat number. There is no blasting media, no chemical and no metal taken off the casting.
- Benchtop fibre laser markerThe LLM-F30 from their fibre laser marker range marks a stainless ID tag for each part with the part type, the casting batch and a 2D code linked to the part’s record. The tag stays readable after the casting is dirty again on site.
AM.CO.ZA For Sunnyrock Yard Tags
Danie Venter, our cone circuit adviser, sat in on both demos and asked most of the awkward questions.
“They picked up the phone and gave straight answers on cable length and on how the cleaner copes outside in a dusty yard, then ran both machines in front of us. Nobody else we spoke to came in lower for that build, with the gun, cable and accessories in the quote instead of turning up later as extras. And the housings, the listed spares and a team you can reach by name told us this was workshop kit, not a gadget.”Danie Venter, Cone Circuit Adviser

The loop every liner now goes through
- Pick and inspect. The part comes off the rack and is checked against the order and the plant’s worn profile.
- Laser clean. The yard team cleans the seating faces, the lifting points and a patch around the heat number. A jaw plate edge takes minutes, not a morning with a wire brush.
- Mark the tag. The fibre marker etches a stainless tag with the batch details and the code. The mark is dark and sharp, and a slurry hose-down does not shift it.
- Tag and photograph. The tag is wired to the lifting eye and the part is photographed for the customer’s change-out pack.
- Dispatch. The part goes onto a pallet for our delivery and courier runs.
What plant leads notice
- Seats arrive ready to check, so nobody wire-brushes on night shift before a liner goes in.
- If a concave set wears unevenly, we tie it to its batch in seconds and give a real answer.
- Tags stay readable through the campaign, so the before and after photos in our wear notes match the right part.
- The yard is tidier, with no spent media to sweep and no chemical drums to manage.

Tags and cleaning, answered
Do you laser clean every part or only some?
Every jaw plate, mantle, concave and cheek plate that leaves the yard gets its seating faces, lifting points and heat number area cleaned. Screen media and bolt packs go out as they come.
What is on the stainless tag?
The part type, the casting batch and a 2D code that opens the part’s record. The tag is wired to the lifting eye, so it stays with the liner until it comes out of the chamber.
Can you match a tag to my wear log?
Yes. Send us the code or a photo of the tag with your worn profile, and we tie it back to the batch and the date it left Sunnyrock.
Liner change coming up? Send us the worn profile.
We match the parts, clean the seats and tag every piece before it leaves Sunnyrock. Other yard jobs are listed on our projects page.
