Pickling

Advanced Pickling Technology

Our ammunition pickling systems employ proven acidic brightening methods to deliver oxide-free, polished results post-annealing.

Rotary scoop drums feature a specialized scoop design that coops acidic water and immerses cups, cases, and bullets in the acidic solutions like sulfuric acid for rapid full wetting and oxide dissolution, avoiding pumps and nozzles to minimize maintenance and prevent acid degradation—ideal for handling aggressive contaminants from cup annealing.

Rotary drum spray washers enhance this with combined immersion and spray in a helical drum, perfect for continuous processing of large volumes where residues from annealing must be thoroughly flushed. These techniques use bio-stable acids to maintain solution efficacy, extending bath life and reducing downtime. Drawing from industry best practices, our systems optimize pH and temperature for deep cleaning without compromising brass integrity, even in military specs where the annealing iris must remain visible for quality verification.

• Process: Customizable combinations of rotary scoop immersion for acid-safe handling, spray scrubbing for surface brightening, and drum tumbling for bulk continuous cleaning—all adaptable to sulfuric or citric acids for comprehensive oxide and scale removal.
• Outcome: Bright, clean components that improve corrosion resistance, dimensional stability, and downstream processing, ensuring compliance with quality standards while avoiding defects like uneven surfaces or retained residues.
• Control: Intuitive digital interfaces for acid concentration monitoring, temperature control, cycle timing, and automated alerts, guaranteeing repeatable results with minimal operator oversight across varying volume scales.

Precision Pickling Options + Quality Enhancements

Enhance your ammunition pickling with our integrated options, starting with rotary scoop drums that gently scoop and submerge parts in sulfuric acid solutions to aggressively dissolve annealing oxides from cups and cases, restoring pristine conditions for further forming without hotspots or inconsistencies.

Rotary spray options deliver targeted acidic mists in enclosed chambers, ideal for bullets where controlled exposure brightens surfaces while preserving delicate features.

For hybrid efficiency, rotary drum spray washers combine tumbling with multi-stage sprays and rinses, effectively stripping citric acid-soluble residues from neck-annealed cases to maintain the annealing iris in military applications.

Inline rotary basket tank systems offer sequential processing: initial acidic immersion to loosen scale, followed by neutral rinses and hot air drying to prevent spotting on brass alloys.

Our tailored chemistry, including corrosion inhibitors, is sourced from top vendors and private labels through selective partnerships that support our expertise, addressing challenges like variable oxide thickness or water hardness.

With decades of specialized knowledge, we refine formulations—like diluted sulfuric for robust cleaning or citric for eco-friendly brightening—to deliver unmatched capabilities, including on-site audits and adjustments for your setup, always sized to your exact volume from small to extremely large.

• Mechanism: Versatile setups with rotary scoops for acid immersion, sprays for precision brightening, drums for continuous flow, baskets for batch control, and tumbling for multi-function efficiency, supporting sulfuric, citric, or phosphoric acids tailored to annealing residues and alloys.
