(China, Qingdao) In the modern industrial wave, focused on lightweight, environmental friendliness and decorativeness, PVC foam board, due to its lightness, moisture resistance, fire resistance, ease of processing and excellent wood imitation, has become an ideal material to replace traditional wood in areas such as furniture and kitchen units, interior decoration, advertising printing, and transportation. The rapid development of the market places unprecedented demands on slab flatness, density, surface cleanliness and production efficiency. As a leading innovator in the plastic extrusion equipment industry in China, Qingdao Xinrui Plastic Machinery Co., Ltd., drawing on rich technical experience, has successfully developed a new generation high-speed and high-quality production line for PVC foam boards of the "Precision" series. With outstanding stability, flawless surface quality and significant energy efficiency, this line redefines industry standards for PVC foam board production.
The production of PVC foam boards is recognized as a challenging area of extrusion technology due to low melt strength, high temperature sensitivity and difficulties in accurately controlling the foaming process. Qingdao Xinrui engineers directly address key problems, achieving breakthroughs in key technologies:
Solution to the density-strength balance problem: The line is based on “conical twin-screw extruder with precise foam control system”. The use of specially designed screw combinations and low shear temperature control technology ensures uniform mixing of the PVC material with the blowing agent in an optimal melt state. Unique "dynamic balancing and pressure homogenization system" creates a stable melt pressure field in the die, which allows the production of slabs with a fine and uniform cellular structure, a minimal density gradient and at the same time high specific strength. The pore diameter in the core can reach 0.1-0.3 mm, which significantly exceeds the average market level.
Achieving a “mirror” surface and ideal evenness: To meet the stringent surface requirements in the segment of high-end kitchen units and decorative panels, the line is equipped with "multilayer co-extrusion sizing device" and “thermal control system for high-precision mirror rolls”. Thanks to co-extrusion technology, a dense hard layer is formed on the surface of the slab, which is then calibrated by multi-section, high-precision, temperature-controlled mirror rolls. This provides an almost mirror-like surface finish, and the overall flatness error is less than 0.1 mm/m. Such boards can be sent straight away for lamination or printing without significant subsequent sanding, saving customers significant money on further processing.
Full process intelligence, high performance and low consumption: The entire line is controlled centrally via "Xinrui Intelligent Cloud Platform", enabling complete digitalization of the process from dosing and extrusion to sizing, drawing, cutting and bundling. The system includes online quality control (e.g. real-time thickness and density feedback), recipe management, remote maintenance and energy efficiency analysis. Optimized extrusion and cooling design allows for maximum line speeds of up to 1.8 meters per minute (for 18mm thickness), reducing overall energy consumption by more than 25%, significantly improving customer ROI.
Excellent raw material adaptability and flexibility: The design of the line is highly compatible, allowing the stable production of foamed PVC boards using various technologies: free foaming, skin foaming (Celuka process), coated coextrusion. The line easily copes with the production of slabs of various densities (from low 0.35-0.5 g/cm³ to medium and high 0.5-0.8 g/cm³), supports the production of slabs of various colors, thicknesses (3-30 mm) and widths (1220 mm, 1560 mm, 2050 mm, etc.) to order.
Qingdao Xinrui's "Precision" series PVC foam board production line is a powerful engine for the upgrading of related industries:
High-end furniture and eco-friendly furniture industry: Production of high-quality odorless boards with zero formaldehyde content for the facades of kitchen units, bathroom cabinets, and furniture partitions.
Construction finishing and interior design: Production of wall panels, ceiling slabs, bases for exhibition stands, combining aesthetics and fire safety.
Advertising, exhibitions and transport: Production of lightweight and durable billboards, interior panels for trains and cars.
Other innovative applications: Such as imitation wood moldings, profiles for energy-efficient windows and doors.
The line uses clean production technologies that minimize volatile organic compound (VOC) emissions from the start, helping customers achieve green plant certification and sustainability goals.
