📊 Phase I: Quality Inspection Standards (The "Pass/Fail" Gate)
To quote high prices to brands like GAP, Zara, or Coach, your product must pass these tests.
Standard: ISO / ASTM International Standards.
1. Cosmetic Inspection (AQL 2.5)
Color Match: Must match the Pantone Chip under D65 Light Box.
Tolerance: Delta E < 1.0$ (Spectrophotometer) or Visual Match.
Surface:
Pass: Smooth, uniform, consistent gloss/matte level.
Fail: Orange Peel, Sagging (Runs), Pinholes, Dust inclusions, "Fish Eyes" (Silicone contamination).
2. Performance Testing (The Lab)
Adhesion Test (The Most Critical):
Method: Cross-Hatch Cutter (1mm grid). Apply 3M 600 Tape. Pull rapidly.
Standard: ISO Class 0 (0% Peeling). Any flaking at edges = Fail.
Hardness Test:
Method: Mitsubishi Pencil Tester.
Standard: HB to 1H (for Rubber Paint); 2H to 3H (for PU Enamel).
Solvent Resistance (Cure Check):
Method: MEK Rub Test (50 cycles).
Standard: No paint removal, no dulling.
Wear Resistance (RCA):
Method: RCA Paper Tape Abrasion.
Standard: > 200 cycles (for Rubber Paint/Soft Touch).
3. Chemical Resistance (Garment Standard)
Washing Test: 60°C Water + Detergent for 60 mins. (No peeling/fading).
Artificial Sweat: pH 4.7 Acidic Sweat for 24 hours. (No discoloration).
💰 Phase II: Cost Analysis Model (Where the Money Goes)
Painting cost is driven by "Transfer Efficiency" (How much paint actually hits the zipper pull vs. the wall).
1. Cost Factors Breakdown
A. Paint Material Cost (The "Solid Content" Trap)
Concept: You buy Liquid, but you sell Solid.
[QLQ Product] High-Solid PU Enamel:
Price: ~$15.00 / KG.
Solid Content: 60%. (Coverage: ~8 Sq.m/KG at 25$\mu$m).
Cheap Local Paint:
Price: ~$10.00 / KG.
Solid Content: 30%. (Coverage: ~4 Sq.m/KG).
Reality: The "Cheap" paint actually costs more per zipper pull because you need 2x the amount to get coverage.
B. Thinner Cost (The "Vanishing" Cost)
You mix paint 2:1 with Thinner.
100% of the Thinner evaporates. It is a pure consumable cost.
C. Operational Overhead
Electricity: Ovens (Heavy consumer), Air Compressors (Heavy consumer), Air Handling Unit (Clean room).
Labor: Masking and Racking (for Rack Spray) is very expensive. Tumble spray is cheap.
2. Tumble Spray Costing (Per KG)
Scenario: 100 KG of Zipper Pulls (Black Matte).
Paint Consumption:
Tumble Efficiency is high (~90%).
Requirement: ~30g of Mixed Paint per 1 KG of Zippers.
Cost: 0.030kg X $15.00 = $0.45 / KG.
Thinner/Hardener:
~ $0.20 / KG.
Pre-treatment (Adhesion Promoter):
[QLQ] ZAP Dip: ~ $0.15 / KG.
Energy & Labor:
~ $0.50 / KG.
🛑 Total Manufacturing Cost (Tumble):
$0.45 + $0.20 + $0.15 + $0.50 = $1.30 per KG
3. Rack Spray Costing (Per Piece)
Scenario: Large Belt Buckle (High Gloss).
Paint Consumption:
Hand Spray Efficiency is low (~40% hits the part, 60% is waste).
Requirement: ~2g paint per buckle.
Cost: $0.03 / pc.
Labor (Racking/Unracking):
High touch time.
Cost: $0.05 / pc.
Overhead (Booth/Oven):
Cost: $0.04 / pc.
🛑 Total Manufacturing Cost (Rack):
$0.03 + $0.05 + $0.04 = $0.12 per Piece
📝 Phase III: The Boss’s Quotation Strategy
How to Quote to the Customer:
Do not quote based on your cost. Quote based on Value + Risk.
1. The Tumble Spray Formula (Per KG)
Best for small zipper pulls, buttons, rivets.
Mfg Cost: $1.30 / KG.
Rejection Buffer (10%): +$0.13.
Margin (40%): +$0.52.
Base Price: $1.95 / KG.
Add-ons:
Custom Pantone Color (Small Batch): Add $20 fixed "Color Matching Fee."
Rubber/Soft Touch Paint: Add $1.50 / KG (Material is expensive).
[QLQ] Super-Adhesion Guarantee: Add $0.20 / KG (Premium ZAP treatment).
2. The Rack Spray Formula (Per Piece)
Best for Buckles, Logo Plates.
Mfg Cost: $0.12 / pc.
Rejection Buffer (15%): +$0.018. (Dust is a major risk in gloss paint).
Margin (50%): +$0.06.
Base Price: $0.20 / Piece.
