WPC Door Panel Extrusion Die

Detailed Explanation of  WPC Door Panel Extrusion Die Production Process, Equipment Parameters, and Formula Costs

Our company boasts 27 years of experience in the R&D and manufacturing of plastic extrusion dies, making us a leading domestic manufacturer of WPC Door Panel Extrusion Die. Through years of mass production iteration and technological accumulation, we have developed mature die structure design, complete production line equipment, standardized production processes, stable mass production formulas, and a comprehensive after-sales technical system. We can provide domestic and international clients with one-stop solutions for high-precision, high-stability WPC Door Panel Extrusion Die. We also provide full technical support throughout the production process, including production debugging, process optimization, and troubleshooting, effectively solving common problems encountered by clients during mass production such as uneven board surface, uneven foaming, unstable density, molding deviation, and product deformation, helping clients achieve stable mass production of high-quality wood-plastic composite door panels.

2.Regarding product specifications and the structural design of the WPC Door Panel Extrusion Die, our WPC door panel extrusion molds are compatible with most mainstream home decoration and engineering door panel sizes on the market. We can produce standard WPC door panels with widths of 700mm, 800mm, 900mm, and 1000mm, and thicknesses of 40mm, 43mm, and 45mm, meeting the customized production needs of different scenarios and customers. The WPC Door Panel Extrusion Die adopts a scientifically and rationally designed wall thickness structure. The standard wall thickness of the outer wall of the door panel is controlled between 3mm and 6mm, and the wall thickness of the internal reinforcing ribs is halved based on this. This structural design takes into account the product’s hardness, pressure resistance, flatness, and lightweight characteristics, which can effectively improve the overall structural stability of the door panel and prevent quality problems such as deformation, cracking, and dents from occurring in the finished door panel after long-term use, ensuring product yield and quality.

3.In terms of post-processing, after the WPC door panel is extruded, due to the characteristics of the extrusion process, there will be slight flatness deviations on the panel surface. Therefore, standardized post-processing finishing is necessary. The molded door panels require four-sided sanding using a professional sander. Each side of the panel is sanded, removing 1mm of thickness to completely eliminate unevenness, texture, and roughness, resulting in a smooth, uniform surface and providing a high-quality foundation for subsequent surface finishing processes. The sanding equipment boasts a stable operating efficiency of up to 2.2 meters per minute, offering high production efficiency and consistent, uniform sanding results. After sanding, the door panel substrate can be customized with four mainstream surface treatment processes based on market positioning and product requirements: heat transfer printing, paint spraying, overmolding, and vacuum forming. Heat transfer printing offers the lowest overall production cost and highest cost-effectiveness, while paint spraying offers the highest cost but a higher-end finish. Customers can flexibly choose the appropriate process based on their product’s quality level.

4.Regarding production line equipment configuration and parameters, the WPC Door Panel Extrusion Die dedicated production line uniformly uses a 92-type extruder. This equipment must be paired with a dedicated foaming screw to ensure sufficient material plasticization, uniform foaming, and stable density, guaranteeing the quality of the molded door panels from the source. The complete standard production line configuration includes: a dedicated door panel extruder head, four 400 calibrators, a (2+2) meter cooling water tank, and ten dedicated water tank shaping adjustment blocks. The entire equipment is scientifically and rationally configured, providing excellent cooling and shaping effects. The production line achieves a stable extrusion speed of up to 1.0 meter/minute, ensuring strong mass production continuity and high molding stability.

5.Regarding auxiliary equipment, the market price for an offline polishing machine ranges from 60,000 to 90,000 yuan; a large-scale mass production line requires four heat transfer machines, each costing 8,000 yuan, for a total investment of 32,000 yuan. The equipment is mature and fully meets the needs of large-scale standardized WPC Door Panel Extrusion Die production.

6.Our company possesses a dedicated WPC Door Panel Extrusion Die production formula that has undergone long-term mass production verification and boasts extremely high stability. The finished product has a stable density of up to 1.1 g/cm³, with precise formula proportions, fine foaming, compliant board hardness, and resistance to deformation.

7.The complete formula and individual cost breakdown for each ton of finished product are as follows: 5kg high-lead stabilizer (69.5 yuan), 2kg HL-530 foaming regulator (37.2 yuan), 10kg HL-401 accelerator plasticizer (111.65 yuan), 0.8kg PE wax (9.51 yuan), 2.4kg NH-213 foaming agent (49.15 yuan), 2.0kg tri-salt (34.23 yuan), 0.4kg stearic acid (3.75 yuan), 1.0kg Ruifeng HL-200 regulator (17.916 yuan), 4.0kg Ruifeng HL-100 regulator (90.86 yuan), 3.0kg coupling agent (18.945 yuan), 150kg PVC-700 resin (750 yuan), 25kg wood flour (24.3 yuan), and 100kg light calcium carbonate (116.5 yuan). The overall production cost of the complete formula is 4932 RMB/ton. The formula offers high cost-effectiveness, high production tolerance, and consistent and stable finished product quality, making it ideal for long-term, large-scale mass production of WPC Door Panel Extrusion Die.
