High-Standard Quality Management for Reliable Zippers

At Sintez, quality is not a checkpoint—it’s the DNA of every micron in our zipper systems. With 28 years of metallurgical expertise and a vertically integrated production ecosystem, we engineer failure-proof fastening solutions trusted by global brands from Milan to Tokyo. Our quality philosophy: If it bears the Sintez stamp, it survives the impossible.

The Sintez Quality Pyramid

A 360° framework combining Ottoman craftsmanship with Industry 4.0 precision:

1. Material Genome Engineering

• Metal Components:
  Turkish C26000 brass alloy smelted in argon-shielded furnaces (oxygen content <15ppm)
  Zinc-nickel electroplating (8-12μm thickness, ISO 4520 compliant)
  Stress-relieved sliders via cryogenic treatment (-196°C liquid nitrogen bath)

• Textile Elements:
  Core-spun polyester/Kevlar® tapes (1,200D tensile strength)
  Eco-reactive dyes with ISO 105-A02 colorfastness (ΔE ≤1.5 after 50 washes)
  Anti-UV treatment blocking 99% of UVA/UVB radiation

2. Precision Manufacturing Protocol

• CNC Machining:
  5-axis milling of slider prototypes (Ra 0.4μm surface finish)
  ±0.003mm tolerance control on tooth alignment

• Weaving Technology:
  RFID-tracked Jacquard looms with real-time tension monitoring
  3D laser scanning for tape width consistency (3mm–50mm range)

• Assembly Automation:
  AI-guided robotic stations applying 2.5N±0.1N insertion force
  Vision systems detecting sub-50μm defects at 120fps

Our 7-Stage Inspection Odyssey

A journey where only perfection reaches the finish line

Stage 1: Raw Material Forensics

• XRF spectroscopy verifying alloy composition (Cu 68.5-71.5%, Zn balance)

• FTIR analysis of polymer granules (MFI 12g/10min @190°C)

• Microbial resistance testing for dyed tapes (AATCC 30 IIIA standard)

Stage 2: In-Process Gauging

• Dimensional checks every 200 teeth (go/no-go pin gauges)

• Real-time torque monitoring of slider movement (0.8–1.2N·m window)

• Electrostatic discharge tests for anti-static variants (106–109Ω surface resistance)

Stage 3: Accelerated Life Testing

• 50,000-cycle endurance simulators replicating:

  • Arctic conditions (-50°C)

  • Tropical humidity (95% RH)

  • Saltwater spray (5% NaCl)

• Abrasion resistance: Taber test @1,000 cycles (CS-10 wheels, 500g load)

Stage 4: Destructive Analysis

• Tensile testing to failure (Instron 5967, 50kN capacity)

• SEM-EDS examination of fracture surfaces

• Cross-sectional microhardness mapping (HV 0.1 scale)

Stage 5: Functional Validation

• Waterproofness: 24h submersion @3m depth (IP68 equivalent)

• Flame resistance: Vertical burn test (ASTM D6413, char length <100mm)

• EMI shielding: 30MHz–6GHz range (60dB attenuation)

Stage 6: Cosmetic Perfection

• 360° chromatic inspection under D65 lighting

• Tactile audit for burrs/roughness (Ra <1.6μm mandate)

• Logo engraving depth verification (0.15±0.02mm)

Stage 7: Traceability Sealing

• Laser-etched QR codes storing:

  • Material batch ID

  • Machine operator ID

  • Test certification links

• Blockchain-archived quality passports
