Why preparing wire, rod and other continuous products for Conform extrusion by wet blasting is the preferred method, and the best way to maintain conform dies...
Success in the Conform continuous extrusion process - also know as continuous rotary extrusion (CRE) - starts with meticulous preparation. Whether working with wire, rod or strip, feedstock must be clean, oxide-free and consistent to ensure smooth metal flow, reduced die wear and to ensure reliable product quality.
One preparation technique proven to be highly effective is wet blasting, a process that uses fine abrasive in a water slurry to deliver controlled, uniform surfaces.
Why is wet blasting ideal for wire, rod and strip preparation:
• Removes oxides and scale without embedding abrasive or damaging the surface.
• Activates the surface with a fine texture for stable feeding into the Conform wheel and die.
• Minimises stress, avoiding scratches, gouges or work hardening.
• Produces a smoother, more uniform finish than dry blasting.
• Avoids the residues and inconsistencies left by chemical pickling.
• Reduces friction and wear, extending tool life and lowering operating costs.
• Cleaner and safer — no acid waste, no dust.
But the benefits don’t stop there...
Wet blasting for Conform die cleaning
Maintaining dies is just as critical as preparing feedstock. Wet blasting is also an excellent method for cleaning Conform dies:
• Gentle but effective at removing oxides and extrusion build-up.
• Preserves precision surfaces, unlike harsher dry blasting methods.
• Prevents contamination, as the slurry rinses away debris.
• Offers controlled cleaning, using fine media and low pressures to protect die geometry.
• Extends die life and improves consistency in production.
After blasting, dies simply need to be dried and protected against corrosion to return to service.
✅ In short: Wet blasting not only ensures that wire, rod and strip enter the Conform process in optimum condition, but also provides a safe, consistent and reliable way to maintain Conform dies themselves.
