Raw Material Inspection
Quality starts at the source. Every batch of nylon and stainless steel is tested for melting point, density, moisture, and flame resistance.

Quality Testing Overview
At HCT, you care about more than just products — you care about the data behind every batch. Each cable tie is tested in our lab from raw material to shipment, meeting global standards.

Testing System & Standards
Our quality system is built on ISO 9001, covering incoming, in-process, and outgoing checks. Test methods follow UL, IEC, and ASTM standards for globally recognized results.
HCT serves multiple industries — engineering, construction, automotive, electrical, and outdoor solar — with test plans tailored per application. Tell us your standards and we'll match the test scope to what you ship.
Test Methods
Six Lab Tests on Every Batch
Tensile Strength Testing
Tensile machines simulate real installation conditions and verify breaking force across widths and temperatures — so the locking head holds under load.
Salt Spray Testing
For outdoor, coastal, and humid use, we run 48–500 hour salt spray tests per ASTM B117 to ensure corrosion resistance.
Flame Retardant Testing
Vertical burning tests confirm self-extinguishing time and ratings, meeting UL94 V-2 / V-0 standards for electrical and energy-sector ties.
Weathering & UV Resistance
UV aging and thermal cycle tests guarantee no fading or strength loss for outdoor exposure — critical for solar projects, signage, and rooftop installs.
Dimensional & Visual Inspection
Calipers and optical projectors check tie width, tooth spacing, tail flatness, and color uniformity — the small details that define perceived quality.
Final Step
Final Inspection & Test Reports
Each batch passes OQC (Outgoing Quality Control) checks before shipping. Every carton has a unique lot code linking back to material, process, and test records — so traceability is end-to-end.
HCT provides tensile, salt spray, flame, and RoHS/REACH reports for every batch, supporting global audits and compliance reviews.
