PVC edge banding production line

Product General Information:

Commercial Terms of Products:

Description:

The PVC edge banding production line is an automated plastic profile equipment system specifically designed for continuous extrusion, embossing, cooling, traction, and cutting of PVC decorative edge banding. This product is widely used for edge cladding in panel furniture (such as cabinets, wardrobes, office desks), customized home furnishings, and woodworking products, serving the purposes of protecting the substrate, enhancing the appearance, and providing moisture-proof edge banding.

1. Raw material drying and feeding system: PVC powder or granules need to be dried at 60–80℃ for 2 hours to prevent bubbles; equipped with an automatic suction feeder + mixing barrel, which can add CaCO₃, CPE, ACR processing aids, color powder/masterbatch, etc.

2. The common models of single screw extrusion mainframes are SJ-50 and SJ-65 (with screw diameters of 50mm or 65mm), featuring an aspect ratio L/D of 25:1 to 30:1. They are designed with a barrier section to enhance the uniformity of plasticization, and have a temperature control accuracy of ±1℃.

3. Screen changer: Manual or hydraulic screen changing (120–200 mesh), filtering impurities to ensure surface smoothness.

4. Hanger-type T-die Head: The width is adjustable (up to 80mm), and the die lip gap can be finely adjusted from 0.3 to 3.5mm, ensuring a thickness tolerance of ≤±0.05mm.

5. Three-roller calender (key component) High-precision mirror roller (hardness HRC60+), with independent temperature control for upper/middle/lower rollers (water cooling or oil heating), achieving high gloss, matte or embossed surface; automatic adjustment of roller gap.

6. Tractor: Composite traction with rubber roller and steel roller, servo control, speed range of 0.5–20 m/min, constant tension to prevent stretching deformation.

7. Online thickness gauge (optional) Beta-ray or infrared thickness measurement, real-time feedback of thickness data, closed-loop control for die head fine adjustment.

8. Cooling conveyor table: With a length of 3-6 meters, equipped with air cooling and water mist spraying, ensuring the board is fully set.

9. Automatic cutting and winding system

• Straight bar cutting: using a flying knife or saw blade, with a length adjustable from 100 to 3000mm;

• Roll winding: Constant tension central winder, with a winding diameter of Φ200–600mm, suitable for use with automatic edge banding machines.

Competitive Advantage:

In the current plastic building materials equipment market, the single-screw extruder PVC edge banding production line still holds significant competitive advantages among small and medium-sized enterprises and regional manufacturers, thanks to its high cost-effectiveness, mature technology, easy operation and maintenance, and rapid production capacity. Although twin-screw or co-extrusion lines have made some progress in the high-end field, the single-screw solution still dominates mainstream PVC edge banding production.

I. Low energy consumption, optimized operating costs

The single screw structure is simple, with less shear heat and stable host current;

The comprehensive electricity consumption per ton of product is approximately 300–380 kWh, which is 15%–25% lower than that of twin screws;

No need for complex vacuum exhaust or side feeding systems, resulting in lower maintenance and energy consumption.

Competitive Advantage: Amidst the continuous rise in electricity prices, a production line with an annual capacity of 500 tons can save electricity costs of 80,000 to 150,000 yuan per year.

II. Mature and stable process, high yield rate

PVC edge banding has a homogeneous single-layer structure, and the requirements for plasticization uniformity are moderate, which can be fully met by a single screw;

With the combination of a barrier-type screw and a precision T-shaped die head, the thickness tolerance can be controlled within ±0.05mm;

The surface has a high degree of smoothness, and it can be used in automatic edge banding machines (such as Homag and Imag) without requiring secondary processing.

Competitive Advantage: The qualified rate of finished products generally reaches over 98%, significantly higher than that of early simple equipment (<90%), reducing waste material losses.

III. Fast flexible switching, adapting to multiple product category needs

By replacing key components, product types can be quickly switched on the same production line:

Switching content Time Application scenario

Change of die head (width/thickness) ≤ 1 hour From 18mm solid color strip to 30mm wood grain strip

Replace embossing roller 30 minutes Smooth surface → Synchronous wood grain (imitation oak, walnut)

Adjust formula (hard-soft switch) 2 hours Hard strip (0.8mm) → Soft strip (2.0mm with DOP)

Competitive Advantage: Meet the supply chain needs of customized home furnishing with small batches, multiple designs, and fast delivery, enhancing customer loyalty.

IV. Easy to maintain and low failure rate

The single screw structure features no gearbox or complex transmission, resulting in fewer mechanical failure points;

The localization rate of vulnerable parts (screw, barrel, die lip) is high, resulting in low replacement costs

The operation interface is mostly composed of PLC and touch screen, with strong parameter memory function, so new employees can be trained and start working in just one day.

Competitive advantage: The comprehensive equipment availability rate can reach 95%+, which is much higher than that of complex production lines (80–85%).
