OEM & ODM Custom Manufacturing for PVC & WPC Panels
OEM & ODM Overview
Hangzhou Chitu operates dedicated extrusion and multi-layer lamination lines for custom PVC foam boards, WPC panels, and laminated sheets. Production parameters are adjusted directly at the extruder die head and calibration table to match specific structural, mechanical, and visual requirements. Operations support full-scale contract manufacturing, private-label packaging, and proprietary polymer formulations tailored to regional regulatory and mechanical performance standards.
Customization Options
Polymer Formulation:
Adjustments for UV stabilization, anti-yellowing agents, or specific flame-retardant ratings (UL94-V0, DIN 4102 B1).
01
Core Structure:
Free-foam PVC, Celuka rigid-skin PVC, wood-plastic composite (WPC), or co-extruded multi-layer structures.
02
Dimensional Customization:
Non-standard widths, cut-to-length options, and strict thickness tolerances managed via inline thickness scanning.
03
Surface Treatments:
High-gloss, matte, embossed, or structured finishes applied via hot-melt lamination or co-extrusion.

Size, Thickness & Density
| Parameter | Specification Range | Industrial Application Focus |
| Thickness | 1mm - 30mm | Thin gauges for signage; thick gauges (15mm+) for cabinetry & structural cores |
| Standard Widths | 915mm, 1220mm, 1560mm, 2050mm | Optimized for CNC cutting and minimal scrap generation |
| Standard Lengths | 2440mm, 3050mm, 3050mm+ (Custom cut-to-length) | Containerized shipping optimization |
| Density | 0.35 g/cm3 - 0.90 g/cm3 | Low density (0.35-0.50) for lightweight signage; High density (0.60-0.90) for high screw-retention cabinetry |
Lamination & Co-Extrusion
PUR Hot-Melt Lamination:
Continuous roller application utilizing polyurethane reactive adhesives resistant to thermal fluctuations and high humidity, exceeding standard EVA adhesive bond strength.
Co-Extrusion Technology:
Fuses a rigid, smooth solid PVC skin layer simultaneously with a lightweight cellular core during extrusion, producing a pinhole-free outer shell optimized for direct digital printing, painting, or routing.
Packaging & Branding
Surface Protection:
Low-tack PE protective masking film applied to single or both sides to prevent scratching during handling and CNC routing. Laser-safe films available.
Palletization:
Fumigation-free wooden pallets or heavy-duty corrugated export boxes secured with edge protectors and moisture barriers.
Private Labeling:
Custom printed protective film featuring corporate logos, barcode labeling, and customized carton marking for wholesale distribution.
Specification & RFQ Evaluation:
Technical review of drawings, density targets, fire ratings, and volume projections.
Laboratory Formulation & Sample Approval:
Sample extrusion and physical testing (density, screw-holding, peel strength) shipped for verification.
Tooling & Setup Confirmation:
Final sign-off on extrusion dies, embossed roller textures, and custom color chips.
Mass Production & Inline QC:
Automated extrusion monitoring with continuous gauge and density checks.
Final Inspection & Container Loading:
Pre-shipment inspection (PSI) reports covering dimensional accuracy, squareness, and packaging integrity.
Custom Manufacturing & Quality Control
Density & Hardness Testing:
Regular checks using densitometers and Shore D durometers to verify structural integrity.
Screw Withdrawal Resistance Test:
Evaluated according to ASTM standards to ensure cabinet hinges and fasteners maintain secure grip over time.
Thermal Dimensional Stability Test:
Panels undergo heat-exposure testing in chambers to monitor linear expansion and warping tendencies.
Peel Strength Testing:
T-peel testing for laminated boards to guarantee adhesive bond durability under high-humidity conditions.
