WPC Frame Extrusion Die

WPC Frame Extrusion Die Production Knowledge and Mass Production Formulation Explanation

1.Our company has 27 years of experience in plastic extrusion die R&D and manufacturing. In the field of WPC Frame Extrusion Die, we possess mature die design, equipment matching, production processes, and a stable formulation system proven through mass production. We can provide customers with complete production technology references and after-sales technical support, promptly resolving various production difficulties encountered during mass production, helping customers stably produce high-quality WPC door frame profiles.

2.WPC door frame profiles are available in multiple mainstream market specifications. Available door frame widths include 70mm, 80mm, 90mm, 100mm, 150mm, 200mm, 220mm, 250mm, 260mm, and 300mm, adaptable to different door opening sizes and for use with various interior door sets and commercial doors. In terms of profile structure design, WPC Frame Extrusion Die strictly controls standard wall thickness: the outer wall thickness of the main frame is set at 3-4mm, while the internal reinforcing ribs have a wall thickness halved; the wall thickness of the matching plug-in connectors is controlled at 1.7-2.0mm. This reasonable wall thickness ratio balances the overall structural strength, deformation resistance, and raw material costs, ensuring long-term stable and reliable use of the door frame.

3.Regarding post-processing, WPC door frame profiles have good surface flatness after extrusion molding, eliminating the need for sanding the substrate. After molding, they can be directly coated, wrapped, or heat-transfer printed for surface decoration, significantly simplifying production processes and saving on post-processing equipment and labor costs. It is important to note that the matching L-shaped plug-in connectors are not suitable for heat transfer printing; customers can choose other finish options as needed when scheduling surface processing.

4.Regarding the production line equipment and standard configuration for WPC Frame Extrusion Die, a 65-type extruder is typically used for producing WPC door frames. A dedicated foaming screw is required to ensure thorough plasticization of the PVC and wood flour blend, resulting in uniform and stable foaming and effectively reducing density fluctuations and localized poor foaming. The standard configuration for a complete WPC Frame Extrusion Die set includes: an extruder head, three 260mm shaping dies, one 2-meter cooling water tank, and five water tank shaping adjustment blocks. The entire shaping and cooling system is rationally designed, allowing for a stable production speed of up to 1.5 meters per minute, meeting the needs of medium-scale continuous mass production.

5.Our company possesses a dedicated WPC Frame Extrusion Die production formula that has undergone long-term mass production verification and demonstrates exceptional stability. The finished product achieves a stable density of 1.1 g/cm³, with precise formula proportions, fine foaming, compliant profile hardness, and resistance to deformation.

6.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 Frame Extrusion Die.

7.Based on over twenty years of practical experience in extrusion die manufacturing, customers encountering problems such as uneven material output, abnormal foaming, dimensional deviations, or profile deformation during production. They can contact AONA EXTRUSION TOOLING at any time, where experienced engineers will provide timely and professional technical services to ensure stable production of WPC Frame Extrusion Die.
