Extrusion calibration units allow precise gauge control across continuous sheet and profile production.
Sheet Thickness Range: 1.0 mm to 30.0 mm (Thickness tolerance: ±0.1 mm for 1–3 mm gauge; ±0.2 mm for 4–10 mm gauge; ±0.3 mm for >10 mm gauge).
Sheet Width Options: Standard 1220 mm (4 ft), 1560 mm, 2050 mm; custom width slitting available down to 610 mm.
Profile & Trim Cross-Sections: Custom extruded profiles engineered up to 300 mm cross-sectional width with tight wall-thickness tolerances.
Length Specifications: Standard 2440 mm (8 ft), 3050 mm (10 ft); continuous inline cross-cutting up to 5800 mm for container loading optimization.

Formulation blending systems accommodate specific visual and functional surface requirements.
Color Matching: Custom masterbatch formulation based on RAL, Pantone, or physical reference samples. Spectrophotometer verification ensures Delta E < 1.0 batch-to-batch consistency.
Surface Finishes: Smooth matte, high-gloss, protective skin layer, woodgrain embossing, linear grooves, and co-extruded cap layers.
Protective Film Application: Single-side or dual-side custom printed PE protective film with brand logo, directional arrows, and grid lines for fabrication alignment.

Additive formulations and screw configuration adjustments enable functional mechanical modification.
Core Density Control: Adjustable foam density from 0.45 g/cm³ (lightweight display boards) to 0.80 g/cm³ (high-strength structural cabinet sheets).
UV Stabilization: Addition of light stabilizers and titanium dioxide concentrations for prolonged outdoor weathering resistance.
Fire Retardancy: Formulated to meet UL94 V-0 and Class B1 flame spread compliance.
Antimicrobial Integration: Homogeneous distribution of silver-ion antimicrobial additives throughout the core matrix, tested to inhibit bacterial proliferation.

Export packaging options configured for containerized shipping, protection against moisture, and retail distribution.
Private Labeling: Custom carton printing, barcode labeling, edge tape branding, and pallet tag identification.
Packaging Methods: PE film bundling, protective corner guards, wooden palletizing with steel strapping, or direct floor loading with water-resistant wrapping.
MOQ Thresholds: Standard customization starts at 3 metric tons per profile/color run, or 1 x 20ft container equivalent for custom sheet dimensions.

Engineering collaboration covering raw material selection to continuous extrusion verification.
Feasibility Analysis: DFM review of customer-provided CAD drawings (.DXF, .DWG, .STEP) to evaluate extrusion wall thickness uniformity and cooling contraction risks.
Tooling Development: Design and machining of custom extrusion dies and sizing calibrators, with initial steel tooling completed within 15–25 working days.
Sample Validation: First-article sample inspection covering dimensional tolerances, weight verification, thermal stability, and surface appearance prior to mass production authorization.

Production Facilities
Extrusion workshops feature high-torque parallel twin-screw extruders, continuous temperature-controlled calibration tables, multi-roller haul-off units, and automated precision cross-cut saws.

Process Control
Raw material mixing relies on automated gravimetric dosing systems to maintain exact resin, stabilizer, foaming agent, and pigment ratios across extended production runs. Melt temperature, pressure, and line speeds are digitally monitored to eliminate internal voids and density variations.

Incoming Material Inspection
Virgin PVC resin batches are verified for viscosity and purity. Additives, pigments, and stabilizers undergo moisture analysis, particle size verification, and dispersion testing prior to formulation loading.

Product Inspection
Quality protocol dictates mandatory scheduled checks across every production shift:
• Dimensional Tolerances: Digital caliper and micrometer measurements for thickness, width, diagonal squareness, and profile wall thickness.
• Density Verification: Water displacement testing for core density uniformity.
• Surface & Color Integrity: Spectrophotometer color difference checks (Delta E) and visual inspection under standardized D65 lighting.
• Mechanical & Thermal Testing: Impact resistance tests, screw pull-out force evaluation, and thermal shrinkage testing (140°C heat exposure).

Sample-to-Production Consistency
Retained pre-production reference samples and digital extrusion parameter logs serve as the baseline for every re-order. Batch production will not proceed without matching the physical reference standard's density, color coordinates, and surface sheen.

Export Packaging
Palletized shipments utilize heat-treated fumigated wooden pallets, heavy-duty edge guards, transparent stretch wrapping, and steel or plastic strapping to prevent shifting, moisture penetration, or transit damage during ocean transport.
