PVC production line technology encompasses core stages such as raw material processing, extrusion and plasticization, vacuum sizing, and cooling/cutting. Process parameters vary significantly based on pipe diameters (e.g., 20–63mm, 75–250mm, 315–630mm, 630–1200mm for drainage or water supply pipes) and materials (rigid PVC, PVC-C). The core technical focus of PVC multi-layer co-extrusion pipe lines lies in ensuring material compatibility, maintaining uniform layer thickness, and achieving high-speed synchronous control. By merging molten materials with distinct properties within a composite die head, the resulting pipes combine functionalities such as barrier properties, strength, and corrosion resistance; these are widely used in applications like oxygen-barrier pipes, aluminum-plastic composite pipes, and large-diameter sewage pipes. Core Process Flow and Key Technical Data PVC pipe production typically employs a conical twin-screw extrusion process. The standard workflow is: raw ma...

Core Processing Performance Advantages of BEISU Conical Twin-Screw Extruders : **Naturally Suited for Heat-Sensitive, High-Viscosity Materials:** Featuring a unique conical screw structure combined with a counter-rotating design, the system maintains low circumferential screw speeds and minimal shear rates. Consequently, heat generation during processing is significantly lower than that of parallel twin-screw extruders. This fundamentally prevents the thermal degradation—caused by overheating—often seen in heat-sensitive materials like PVC. This not only guarantees superior product performance but also allows for a reduction in the amount of heat stabilizers required, thereby helping enterprises lower raw material costs. **Dual Compression Ratio for More Thorough Plasticization:** The conical structure generates a dual compression ratio through the simultaneous effects of a "gradually increasing screw diameter" and a "gradually decreasing screw channel depth." The o...

To choose the right rotomolding mixing system, you need to look beyond generic powder blenders. Because rotomolding relies entirely on gravity and thermal conduction inside the mold, your mixing system must produce a highly uniform, free-flowing powder where pigments and additives perfectly adhere to the resin particles without causing them to clump or degrade. A1: Choose Based on Your Production Capacity The size and type of your mixing system should match your throughput requirements. Mixing systems are rated by total volume and effective volume (usually 70% of total volume). Small to Medium Batch Production (Under 300 kg/hr): A standalone High-Speed Vertical Dry Blender (Turbomixer) is usually sufficient. You can run individual batches, discharge them into storage bins, and let them cool naturally if your cycle times allow. High-Volume / Continuous Production (Over 500 kg/hr): You need a Heating/Cooling Mixer Combination Unit (Vertical Hot Mixer + Horizontal Cold Mixer). The hot mi...

How to Calculate BEISU Production Capacity of PVC Profile Production Line? A1. Calculation Based on Basic Theoretical Capacity (Theoretical Capacity Formula) Core Formula: Theoretical Capacity = Equipment Extrusion Rate (kg/h) × Effective Production Time (h). The unit of measurement is kilograms (kg) or tons. Specific Calculation Steps: **Step 1: Determine the Equipment Extrusion Rate:** For standard PVC profile production lines, the extrusion rate typically ranges from 100 to 115 kg/h (specifically for standard door and window profiles). For larger-scale lines, this rate can reach 150 to 200 kg/h, representing a high-capacity line. **Step 2: Calculate the Effective Working Time:** Deduct downtime required for equipment maintenance and mold changes. Typically, the "Daily Effective Production Time" is calculated based on the actual scheduled shift duration (e.g., 8 hours per shift). For a 16-hour, two-shift operation, approximately 10% of the scheduled time should be deducted...

 How to Select the BEISU Extruder for Sealing Strip Production First, Select the Screw Type: Matching Raw Material Characteristics The mainstream raw materials for sealing strips fall into three categories, each corresponding to a specific screw configuration: **EPDM and Silicone Rubber:** Best suited for *vacuum-vented, cold-feed single-screw extruders*. These machines can directly process room-temperature rubber compounds—eliminating the need for a preheating step—and produce bubble-free products, making them ideally suited for the processing requirements of rubber-based sealing strips. **PVC, PP, PE, and Other General-Purpose Plastics:** Best suited for *standard single-screw extruders*. For small cross-section profiles, a smaller single-screw extruder helps avoid waste of resources and energy while fully meeting the extrusion molding requirements for plastic-based sealing strips. **High-Filler Formulations, Modified Plastics, or Wood-Plastic Composites:** Best suited for *conic...
