Why our plastic profile extruder stands out

High capacity Conical Twin-Screw Technology: Specially designed to process PVC powder with high-calcium carbonate filling. The conical twin-screw geometry paired with a high-torque distribution gearbox delivers excellent progressive compression and uniform thermal melt stability, maximizing cost efficiency and throughput.
Wide-Profile Die Head with Optimized Flow: Engineered with advanced streamlined coat-hanger flow channels to ensure balanced melt distribution across widths up to 600mm+. It completely eliminates internal weld lines or stagnation points, resulting in highly uniform inner ribs and outer skin thicknesses.
Expanded Vacuum Calibration Table: Features an extra-wide stainless steel calibration surface equipped with intensive multi-stage water cooling blocks and high-vacuum negative pressure zones. This locks the complex hollow internal rib structure into perfect shape without sagging or warping.
Synchronized Heavy-Duty Downstream Line: Features a wide-track caterpillar haul-off, a zero-dust transversal knife/saw cutter, and an automated stacking rack. All units are fully synchronized via a central PLC touch-panel controller, creating a reliable 24/7 automated production flow.

The MIDTECH PVC ceiling and wall panel extrusion line is a highly robust and versatile manufacturing system engineered for the building decoration and construction materials industry. It is widely used to produce high-gloss PVC ceiling tiles, wide interior wall panels, decorative marble-look panel foundations, and hollow WPC (wood-plastic) wall claddings. Our lines stably handle various raw material formulations to meet international building standards for impact resistance and flame retardancy, covering production widths typically from 150mm up to 600mm .

FAQ

Why do you use a Conical Twin-Screw Extruder instead of a Single-Screw Extruder for PVC panels?

PVC panels are manufactured using dry-blended PVC powder combined with stabilizers, processing aids, and high amounts of calcium carbonate filler to reduce raw material costs. Single-screw extruders cannot efficiently feed or homogenize raw powder mixes directly. The Conical Twin-Screw Extruder is the industry gold-standard because its tapered design provides immense positive-displacement pumping, excellent progressive physical mixing, and the high head-pressure needed to force materials evenly across wide panel dies.

Can a single production line produce different widths and designs of wall panels?

Yes, the line offers great production flexibility. By keeping the main extruder and downstream machines, you can produce different panel widths (e.g., changing from a 200mm ceiling panel to a 300mm wall panel) or different rib designs by simply swapping out the extrusion die head and the calibration sizing sleeves. The modular vacuum table and adjustable wide haul-off can easily accommodate different sizes within its model range.

How are the decorative patterns (like wood grain or marble) applied to the PVC panels?

There are two main methods, and MIDTECH can integrate both downstream: Online/Offline Hot-Stamping: A specialized hot-stamping machine transfers a decorative foil pattern directly onto the hot surface of the PVC panel using heat and pressure right after calibration. Offline Lamination: The extruded panel base is passed through a lamination machine where a durable, printed PVC decorative film is glued onto the panel surface, which is ideal for textured, premium wood or stone finishes.

What is the purpose of a secondary co-extruder on a panel production line?

An optional secondary co-extruder is often used to save material costs. It allows you to use recycled PVC or highly filled, lower-cost material for the main thick core of the hollow panel, while the co-extruder pushes a thin, pristine layer of virgin PVC onto the outer visible surface. This ensures the panel looks premium and bonds perfectly with decorative foils while significantly reducing overall manufacturing costs.
