Product Introduction
This production line is a professional conical twin-screw extrusion equipment, mainly used for the production of PVC wood veneer panels, bamboo-wood fiber integrated wall panels, carbon crystal boards, indoor decorative wall panels, and other sheet products. The equipment is compatible with high-calcium powder and wood powder filled modified formulas, producing panels with high hardness, good toughness, waterproof and moisture-proof properties, flame retardancy, environmental friendliness, and zero formaldehyde. These products are widely used in home decoration ceilings, full wall renovations, hotels, office buildings, and commercial decoration fields. The entire production line integrates extrusion, five-roll calendering, online film coating, back-adhesive composite, constant temperature cooling, punching and cutting, and robotic arm stacking into an integrated molding process. It features a high degree of automation, producing finished panels with flat surfaces, uniform density, and no deformation. The manufacturer provides a one-stop service including complete equipment installation and commissioning, formula and process guidance, and technical training.
Process flow
Automatic weighing and feeding → High-speed hot and cold mixing and stirring → Conical twin-screw melting and plasticizing extrusion → Flat die extrusion molding → Five-roll calendering and shaping → Online film coating and lamination → Back-adhesive composite process → Constant temperature cooling trough cooling and shaping → Traction conveying → Precision punching machine length cutting → Robotic arm automatic stacking → Finished product warehousing
Product Advantages
1. Conical twin-screw powerful plasticizing, optimized for bamboo, wood, and high-calcium powder filled formulas, ensures thorough plasticizing, dense and full boards, with no air bubbles or delamination.
2. Equipped with a high-precision shaping and cooling system, it achieves high surface flatness and uniform thickness, significantly enhancing the appearance and grade of the finished product.
3. Supports integrated online film coating and molding, eliminating secondary processing, streamlining production steps, and achieving high production efficiency.
4. Equipped with professional punching machine precision cutting, the cut edges are smooth and burr-free, dimensions are standard, and the finished product pass rate is extremely high.
5. Paired with fully automatic robotic material stacking, the entire process is automated, significantly saving labor, and the production cycle is stable.
6. The equipment operates stably with low noise and a low failure rate. It features high component compatibility and low maintenance costs.
7. One machine serves multiple purposes, flexibly producing various indoor decorative panels such as carbon crystal boards, bamboo-wood fiber wall panels, and PVC decorative boards, ensuring high equipment utilization.
