In the high-stakes world of mining, aggregate processing, and heavy construction, productivity is a battle against friction. Every ton of material moved comes with a cost—not just in energy, but in the gradual, relentless grinding down of your machinery.
If you operate HPGRs (High Pressure Grinding Rolls), dragline buckets, or heavy transfer chutes, you know the drill. Eventually, standard steel gives out. The result? Unplanned downtime, torch-cutting and welding crews on overtime, and a steady drain on your bottom line.
This is where ZZ OLD CRAFTSMAN steps in to change the equation.
The “Old Craftsman” Approach to Modern Problems
While the name evokes traditional durability, the technology is anything but old-fashioned. ZZ OLD CRAFTSMAN specializes in tungsten carbide wear plates—a composite solution designed for the most abrasive environments on earth .
Unlike generic AR400 or AR500 steel that eventually sacrifices itself to the material flow, ZZ OLD CRAFTSMAN utilizes vacuum brazing technology. This process fuses robust tungsten carbide blocks (the hardest material next to diamond) directly onto a steel backing plate.
Why This Matters for Your Productivity
1. The 20x Multiplier
Standard high-chromium cast iron might give you a few weeks of life. According to internal data, switching to ZZ Old Craftsman’s carbide brazed products can extend life by more than 20 times. Imagine changing your liners once a year instead of once a month.
2. Eliminating the “Maintenance Cycle”
In mining and construction, statistics suggest a significant percentage of site accidents occur during maintenance—specifically when handling heavy materials to replace worn parts. By using a super-hardened wear plate that lasts longer, you physically remove your crew from the hazard zone. Safety is productivity.
3. Protecting the Critical Zones
For Dragline operations, the heel and the wear plate zones take the heaviest punishment . If those wear through, you risk damaging the parent bucket—an incredibly expensive repair. By applying ZZ Old Craftsman’s tungsten carbide plates to these high-impact zones, you create a “sacrificial armor” that protects your multi-million dollar asset while remaining easily serviceable .
The Verdict
If your operation is tired of the “patch and weld” cycle, it’s time to upgrade. ZZ OLD CRAFTSMAN offers a clear path to lower cost-per-ton: stop using structural steel to fight abrasion, and start using real carbide armor.
