Airbrush Only Sprays When Releasing Trigger Aluminium Trigger Spray Bottle

1. Product Specification Parameters

2. Production Process Flow

Step 1: Aluminium Material Sourcing & Preparation

• Source 1050/1070 pure aluminium coils from certified suppliers (with material test reports for purity and corrosion resistance).
  - Cut coils into aluminium blanks (size matching bottle capacity: e.g., 150mm diameter blanks for 500ml bottles) via precision laser cutting (tolerance ±0.1mm).

Step 2: Aluminium Bottle Body Formation

• Deep Drawing: Use hydraulic presses (100–150 tons) to draw aluminium blanks into bottle-shaped shells (2–3 passes to avoid material cracking).
  - Trimming & Neck Forming: Trim excess aluminium from the bottle top and shape the neck with 28/410 threads (via thread-rolling machines, ensures tight closure fit).
  - Surface Treatment:
   
  1. Degreasing: Remove manufacturing oils with alkaline cleaners (food-safe, per FDA standards).
  2. Anodization: Electrochemically treat the aluminium surface (10–15μm anodized layer) to enhance corrosion resistance and enable custom coloring (clear, silver, or brand-specific hues).

Step 3: Trigger Mechanism & Valve Assembly (Critical for Release-Spray Function)

• Valve Calibration: Assemble PTFE-sealed valves with stainless steel springs – test to ensure spray activates only on trigger release (no pre-spray; 100% inspection for this function).
  - Trigger & Nozzle Integration: Attach PP triggers to valves and secure brass nozzles (0.3–0.5mm orifice) via ultrasonic welding (no glue, prevents chemical leaching).
  - Function Test: Actuate triggers 50 times per unit to verify consistent spray timing (release-only activation) and mist quality (no drips or uneven flow).

Step 4: Bottle-Trigger Assembly & Leak Testing

• Sealing: Attach the trigger-valve unit to the aluminium bottle neck using food-grade silicone gaskets (torque: 3–5 N·m, ensures leak-proof seal).
  - Leak Test: Fill bottles with water (or client-specified liquid simulant), invert for 24 hours, and apply 0.3 bar pressure – no leakage = pass (100% testing for small orders; 5% random sampling for bulk).
  - Pressure Test: Verify trigger actuation requires 2–3 N of force (ergonomic for repeated use; adjusts for client needs).

Step 5: Finishing & Quality Assurance

• Branding (Optional): Laser engraving or screen printing (food-safe inks) for logos, batch numbers, or usage instructions (compatible with anodized aluminium).
  - Final Inspection: Check for surface defects (scratches, dents), trigger function, and dimensional accuracy (matches spec sheets).
  - Cleaning: Sanitize bottles with UV-C treatment (for food/medical use) to eliminate surface bacteria (meets FDA hygiene standards).

3. Application Scenarios

3.1 Food Processing & Catering

• Use Cases: Applying food-grade 脱模剂 (baking), edible oil (grill seasoning), or antimicrobial sprays (food contact surfaces).
  - Benefits: Release-only spray avoids pre-spray waste of costly edible liquids; aluminium body resists oil corrosion and is easy to sanitize (meets FDA food safety norms).

3.2 Industrial Maintenance & Manufacturing

• Use Cases: Precision spraying of industrial lubricants (gear mechanisms), rust inhibitors (metal parts), or cleaning solvents (electronic components).
  - Benefits: 10–20μm mist ensures even coverage (no over-spray); aluminium withstands harsh solvents (no degradation) and heavy workshop use (drop-resistant).

3.3 Cosmetics & Personal Care

• Use Cases: Airbrush-like application of setting sprays (makeup), facial mists (skincare), or hair serums (salon use).
  - Benefits: Release-only trigger prevents accidental pre-spray (preserves product); anodized aluminium offers premium, customizable branding (matches luxury beauty packaging).

3.4 Agriculture & Horticulture

• Use Cases: Spraying organic pesticides (precision on crop leaves), nutrient mist (hydroponics), or plant growth regulators.
  - Benefits: 5–10cm spray radius targets specific plants (reduces chemical waste); aluminium body resists outdoor moisture (no rusting in greenhouses).

4. Shipping & Logistics

4.1 Packaging for Transit

• Primary Packaging: Individual bottles are sealed in food-grade PE bags (to prevent dust/contamination) – optional shrink-wrapping for multi-bottle packs (e.g., 12-bottle cases).
  - Secondary Packaging: Corrugated cardboard boxes (5-layer, ECT-32 grade) with custom foam inserts (fits bottle shape, prevents movement during transit).
  - Labeling: Each box includes:
   
  • Batch number, production date, and expiry (if applicable);
  • Compliance labels (FDA/EU 10/2011 certification);
  • "Fragile" and "Keep Dry" stickers (for logistics handlers).

4.2 Regulatory Compliance for Global Shipping

• Hazardous Materials (HM): For bottles intended for chemicals/solvents, we provide UN 3H1 packaging certification (meets IATA/IMDG standards for liquid transport).
  - Customs Documentation: Supply a full compliance pack per order, including:
  • Material safety data sheets (MSDS) for aluminium/PP components;
  • FDA/EU 10/2011 certificates (for food/chemical contact);
  • Commercial invoice with HS code (3924.10 for plastic triggers; 7612.90 for aluminium bottles).

4.3 Regional Shipping Options & Lead Times

4.4 Warehousing & After-Sales Logistics

• Inventory Management: Offer 90-day free warehousing for bulk orders (clients can request partial shipments to align with production schedules).
  - Damage Claims: If bottles arrive damaged, we provide replacement within 5 days (requires photo evidence of packaging/units; 0.5% damage rate guarantee).
  - Return Policy: Accept returns for non-customized bottles within 30 days (unused, in original packaging; restocking fee waived for qualified B2B clients).
