Frequently Asked Questions (FAQ)
-
What is the main application of this Krah pipe extrusion machine?
This machine is primarily used for producing large-diameter, spiral-wound plastic pipes (Krah pipes) commonly used in municipal drainage, sewer systems, culverts, and industrial effluent management due to their high ring stiffness and corrosion resistance. -
What does "semi-automatic" mean for this machine?
The semi-automatic operation indicates that core extrusion processes like material feeding, melting, and winding are automated and controlled by the PLC. Certain auxiliary functions, such as pipe cutting or mandrel setup, may require operator intervention, offering a good balance between automation and cost-effectiveness. -
Can this machine process materials other than HDPE?
Yes. While HDPE is the most common material, the machine can also be configured to process polypropylene (PP) and other compatible polyolefins. The screw design and barrel temperatures can be adjusted based on the specific material properties. -
What is included in the "CE Standard Compliant" certification?
This means the machine's design incorporates essential health and safety requirements as per the European Machinery Directive. It covers aspects like electrical safety, mechanical guarding, emergency stops, and risk reduction, facilitating easier export to markets requiring CE marking. -
What is the typical output capacity in terms of pipe diameter and length?
The output capacity depends on the screw diameter selected, material, and wall thickness. Our technical team can provide specific output data (kg/hour) and the corresponding range of pipe diameters (typically from several hundred millimeters up to large diameters) it can produce based on your configuration. -
Do you provide installation and training services?
Yes, we offer comprehensive after-sales services. This can include optional on-site installation supervision, commissioning, and operational training for your technicians to ensure a smooth production startup. -
How is the power supply requirement determined?
The power supply (voltage and phase, e.g., 380V/3Phase/50Hz or 440V/3Phase/60Hz) is customizable based on the destination country's grid standards. We will configure the electrical components accordingly upon request. -
What is your lead time for manufacturing and delivery?
The lead time varies based on the specific configuration and current production schedule. Generally, it ranges from a few weeks to a couple of months. A precise timeline will be provided upon receipt of a formal inquiry and order confirmation.
