We use dedicated inspection gauges for 100% full inspection on every shipment batch to ensure all dimensions fully meet customer requirements.
We carry out strict material dimension measurement for all raw materials before production to ensure every part meets required dimensional standards.
Immerse the WPC test specimen completely in boiling water at 100°C for a specified duration (typically 2–24 hours), then examine changes in water absorption rate, dimensional change rate, surface condition and internal structure.
Apply grease or chemical solvents to the product surface and check for penetration, discoloration, softening or residue formation.
Detect internal uniformity and voids inside the product by measuring the mass per unit volume of the material.
Test the purity, mixing ratio and stability of wood flour, plastic pellets and additives.
Apply continuous pressure and bending loads to test the ultimate bearing capacity of the material.
The moisture content of materials during production is tested with professional equipment.
Test the burning rate, smoke generation and thermal response of the material in a controlled combustion environment.
Compare the colors of different production batches using standard color charts and testing equipment.
Test the residual ash content ratio after high-temperature combustion of the specimen.
Conduct accelerated tests simulating long-term oxidation and UV exposure to measure the material aging rate.
Subject the specimens to low-temperature freezing and thermal cycling tests.
