Testing & Validation.
Empirical validation is the bridge between chemical compounding and real-world part survivability. Our in-house testing laboratory evaluates formulations across nine core physical, mechanical, thermal, and flammability parameters using ASTM standard test methods.
In-House Laboratory Testing (9 Core Tests)
Tensile Strength & Elongation at Break
Measures ultimate mechanical pulling resistance and ductility before break. Essential for load-bearing fan blades and structural housings.
Flexural Modulus & Flexural Strength
Evaluates structural rigidity and deflection resistance under continuous bending loads, preventing blade sag in dynamic air handling parts.
Izod Impact Resistance (Notched & Unnotched)
Determines the compound’s toughness and energy absorption under abrupt shock or drop impacts in stress-concentrated geometries.
Vicat Softening Point (VSP)
Assesses the thermal threshold at which the polymer matrix loses surface stiffness when subjected to localized thermal loads.
Melt Flow Index (MFI)
Measures polymer melt flow rate and viscosity. The foundational baseline test for consistent mold-filling and cycle time stability.
Specific Gravity & Density
Verifies compound density to ensure correct polymer-to-reinforcement ratios and prevent part weight discrepancies.
Ash Content & Glass Fibre Fraction
Loss-on-ignition test accurately measures inorganic filler loading (glass fibre and mineral fillers) across production lots.
Moisture Content Analysis
Monitors residual moisture in hygroscopic compounds (PA6, PA66, ABS, PC) to eliminate splay marks and hydrolytic degradation.
Flammability (UL 94)
Evaluates afterflame duration, self-extinguishing behavior, and flaming drip prevention for electrical housings and appliance components.
Batch Quality Documentation & Test Reports
Laboratory test reports and Certificates of Analysis (CoA) can be generated for customer-specified production campaigns, detailing measured physical, thermal, and mechanical values aligned with agreed purchase specifications.
Verification of tensile strength, flexural modulus, Izod impact resistance, and specific gravity under ASTM test standards.
Melt Flow Index (MFI) at specified temperature and load conditions, moisture analysis, and Vicat softening temperature.
High-temperature muffle furnace ash verification to confirm exact glass fibre and mineral filler percentage loading.
The 5-Stage Validation Lifecycle
From incoming raw resin pellets to final pallet dispatch, every material lot progresses through our locked five-stage quality gate.
Incoming Inward Assay
Melt index, moisture, and density testing on virgin resins, additives, and glass roving.
In-Process Extrusion Checks
Continuous feed rate confirmation, strand diameter gauge, and continuous melt pressure monitoring.
Specimen Injection Moulding
Moulding standard ASTM tensile dogs, flex bars, and impact coupons under controlled cycles.
Specimen Inspection & Metrology
Inspecting test bars for dimensional accuracy, notch precision, and defect-free geometry prior to evaluation.
Destructive Release Testing
Tensile, impact, flexural, VSP, and ash furnace verification against target specifications.
