PU TPU granulation extrusion screen changer

Core Functions and Applicability PU (polyurethane) and TPU (thermoplastic polyurethane) pelletizing processes demand screen changers with specific requirements: temperature resistance, corrosion resistance, and filtration precision: Temperature Resistance TPU processing temperatures typically range from 180-220C, necessitating screen changers with temperature resistance 250C. For instance, dual-column hydraulic screen changers made from alloy steel withstand temperatures up to 300C, meeting TPU

Single-column dual-station Hydraulic screen changer

Wide range of applications: The single-column dual-station screen changer is widely used in plastic extrusion, chemical fiber, rubber, and other fields to help production lines run efficiently! Outstanding advantages: High pressure and high temperature resistance: Made of high-quality materials, it can easily withstand high temperature and high pressure environments! Excellent Sealing Performance: A unique sealing design ensures no melt leakage, guaranteeing product quality! User-Friendly Operat

PU/TPU granulation, a melt pump + automatic screen changer

For PU (Polyurethane) and TPU (Thermoplastic Polyurethane) plastic granulation processes, the melt pump and screen changer system plays a critical role in ensuring stable extrusion, filtering impurities, and improving product quality. Melt Pump: Acts as a positive displacement device to stabilize melt pressure and flow rate, eliminating fluctuations caused by extruder screw design, temperature control, or feed interruptions. Reduces backpressure on the extruder, lowering melt temperature and ene

Operating Guide for Replacing the Filter Screen of a Plate-Type Hydraulic Screen Changer

Before replacing the filter screen of a plate-type hydraulic screen changer , please ensure that all necessary preparations have been made and follow the detailed steps below: 1. Inspect the spare filter station: First, carefully check whether the filter screen has been properly installed on the spare filter station. If not, install the filter screen accurately into the slots of the perforated plate, ensuring it is securely fastened. 2. Confirm the position of the perforated plate: Next, check w

Single-plate screen changer configuration

The configuration of the single-plate screen changer must be selected based on specific process requirements, including core components and parameters. The key configurations include the following: Core Components Main Structure: Utilizes flexible pressure-activated sealing technology to ensure the seal automatically activates and compensates with melt pressure, suitable for high-viscosity materials. Hydraulic System: Compatible with a accumulator hydraulic station to achieve rapid screen changi
