At our facility, quality is engineered into every stage of the rotational molding tooling and production process. We adhere to rigorous inspection protocols to ensure high dimensional accuracy, flawless parting lines, and superior thermal performance.

• 3D CMM & Laser Scanning Verification: Every cast and CNC-machined aluminum mold is scanned against original 2D/3D CAD models to guarantee strict dimensional tolerances (±0.5mm).

• Parting Line & Flange Sealing Test: Precision inspection of CNC-milled parting flanges to ensure airtight closure, zero light leakage, and minimal plastic flash.

• Wall Thickness & Surface Inspection: Ultrasonic wall thickness gauging across complex mold cavities and 100% surface inspection for pinholes, cracks, or texture defects.

• Thermal Conduction & Frame Stress Test: Molds undergo pre-heat structural stress testing on steel skeleton frames to prevent heat distortion during oven rotation.

• Ultrasonic Wall Thickness Gauging: Non-destructive testing across critical stress points, corners, and deep-draw pockets of plastic parts.

• Leakage & Air Pressure Testing: 100% pneumatic pressure or hydrostatic leak testing for fuel tanks, water vessels, and weather-sealed boxes.

• Drop & Impact Resistance Testing: Cold-temperature drop testing (-40°C) and tensile strength analysis to ensure rugged outdoor durability.

• Pre-Shipment Trial Run & Sample Sign-off: Every custom mold undergoes a complete sample trial run (T1/T2 samples provided with full inspection reports) before final dispatch.
