Sinobakr Precision Cleaning – Professional Washing Solutions for Stamped Components

Sinobakr boasts years of experience in industrial precision cleaning and provides integrated cleaning systems for all types of stamped metal parts, including automotive stamped structural parts, new energy battery shell stampings, electrical hardware stamping, stainless steel deep-drawn parts, hardware terminal stamping, and household appliance metal pressings. Our targeted solutions eliminate typical stamping contaminants and production defects such as drawing oil, stamping emulsion, iron powder, burr debris, surface water stains, spot rust, and inconsistent cleanliness, complying with automotive component cleanliness standards and electronic assembly quality requirements.

I. Core Cleaning Pain Points of Stamped Parts & Matching Solutions

1. Main Contaminants on Stamped Workpieces

Stamping oil, drawing lubricant, cold rolling emulsion, iron filings, fine metal powder, stamping dust, protective film adhesive residue, fingerprint grease, and slight surface oxidation.

2. Typical Production Challenges

1. Complex shapes, deep cavities, folded edges, blind grooves and overlapping areas easily trap oil and metal particles, leading to residual contamination after cleaning.

2. Thin stamped sheets are prone to deformation under high-pressure flushing; improper ultrasonic power causes surface scratch and cavitation marks.

3. Carbon steel and iron stampings quickly develop rust spots if moisture or cleaning agent remains on the surface after drying.

4. Large-batch stamping production requires fast cycle times; manual cleaning fails to guarantee stable cleanliness and high output.

5. Adhesive residues from protective films and viscous drawing oil are difficult to remove with ordinary single-tank cleaning equipment.

3. Standard Acceptance Specifications

No visible oil film or particle residue on surfaces; free of watermarks, stains and rust; fully dried without hidden liquid inside folded gaps; suitable for direct spraying, electroplating, welding and assembly post-cleaning.

II. Three Mature Complete Cleaning Systems for Stamped Parts

Solution A: Full-Automatic Conveyor Aqueous Ultrasonic Cleaning Line

First choice for mass production of large-volume stamped hardware, battery casings, automotive thin stamping parts

Applicable Workpieces

New energy battery aluminum/steel casings, automotive sheet metal stampings, home appliance metal shells, mass-produced electrical terminals, standard hardware pressings.

Standard Process Flow

Automatic feeding → High-pressure spray pre-degreasing → Multi-stage ultrasonic rough & fine cleaning → Multi-tank pure water overflow rinsing → Air knife water blowing → Hot air circulation drying → Continuous discharging

Core Advantages

1. High continuous throughput: Conveyor inline design realizes non-stop mass production, hourly capacity up to tens of thousands of pieces.

2. Mild adjustable ultrasonic power: Avoid thin stamping deformation and surface scratches while removing oil and powder thoroughly from folded edges.

3. Low operating cost: Water-based detergent with low consumption, no expensive solvent recovery cost, eco-friendly with simple wastewater treatment.

4. Custom carrier fixtures: Mesh baskets and special hanging racks prevent stacking and mutual scratch of stamped sheets.

5. Fully enclosed dust-proof structure, easy to connect with stamping presses for automatic production linkage.

Solution B: Vacuum Hydrocarbon Cleaning Machine for High-Precision Thin Stampings

For stainless steel deep-drawn parts, electronic precision terminals, visible surface decorative stampings with high appearance requirements

Applicable Workpieces

Stainless steel deep drawing shells, precision electronic terminals, consumer metal appearance parts, thin-wall precision stamped components requiring electroplating or anodizing.

Standard Vacuum Sealed Process

Batch loading with special anti-scratch tooling → Vacuum ultrasonic cleaning → Multi-stage solvent vacuum rinsing → Distillation solvent regeneration → Full vacuum low-temperature drying → Nitrogen protection unloading

Core Advantages

1. Zero watermark & anti-rust effect: Vacuum drying eliminates all moisture, ideal for stainless steel and carbon steel decorative parts without discoloration.

2. Strong dissolving capacity for viscous drawing oil: Solvent penetrates deep into folded and hidden gaps to dissolve heavy lubricant residues.

3. No surface corrosion risk: No water ion residue, avoiding staining before electroplating, painting and surface treatment.

4. Closed solvent circulation with 98% solvent recovery, low VOC emission, explosion-proof and environmentally compliant.

Solution C: Multi-Station Rotary Basket Water-Based Cleaning Machine

For medium-batch small to medium stamped parts with irregular shapes

Applicable Workpieces

Small hardware stamping connectors, lock parts, small automotive fastener stampings, batch mixed-size pressings.

Process Features

Rotary basket swing cleaning combined with ultrasonic and internal spray; all-round flushing of inner and outer surfaces of irregular stampings; small footprint, flexible switching of different workpiece specifications, suitable for factories with medium output and limited workshop space.

III. Exclusive Sinobakr Core Technologies for Stamped Parts

1. Adjustable Low-Damage Ultrasonic Control SystemDual-frequency ultrasonic modules with power gradient adjustment, which reduces cavitation impact force to protect ultra-thin stamped sheets while maintaining efficient decontamination.

2. Multi-Level Circulation Filtration SystemCoarse filter mesh + 5μm fine filter + magnetic iron removal device continuously intercept iron powder and metal chips, preventing secondary scratch on stamped surfaces.

3. Anti-Rust Drying Combination TechnologyHigh-strength air knife plus segmented hot air circulation drying; targeted air blowing for folded edges and deep cavities to eliminate hidden residual water, equipped with temporary anti-rust agent dosing system for carbon steel stampings.

4. Modular PLC Automatic Production ControlPre-set dedicated cleaning programs for battery casings, automotive stampings and electronic terminals; one-click parameter switching, with full data recording for quality traceability.

5. Customized Stamping Workpiece Fixture DesignCustom mesh baskets, hanging frames and separation carriers to solve stacking, deformation and incomplete cleaning problems of folded, deep-drawn stamped products.

IV. Typical Industry Application Cases

1. New Energy Vehicle Battery Shell StampingsInline conveyor aqueous ultrasonic cleaning line, matched with stamping machine automation linkage; removes drawing oil and aluminum powder completely, no watermarks before laser welding, zero welding defect rate.

2. Automotive Body & Chassis Stamped PartsLarge-pass conveyor cleaning line with high-pressure pre-spray function; meets workshop mass production demands, stable cleanliness before electrophoresis and painting.
