PVC four cavities pipe production line is composed of conical twin-screw extruder 65mm, 4 cavity mould, 4 cavity coling calibration tank, 4 station haul off, 4 station cutter and 4 station tipping table.
PVC four cavities pipe production line can extruder four pipes at same time on one machine. This PVC pipe extrusion line can save investment cost in factory buiding and production, which increase the capacity a lot and reduce production time. SJSZ65 conical twin-screw extruder can easily reach 5.5-6.5 ton/per day,the production speed take 16mm as example can get more than 8-10m/min.

PVC pipe extrusion line adopt advanced technology from twin conical screw extruder to the down-stream line of four-outlet stainless steel vacuum calibration tank and spray cooling tank. This design will avoided the energy and materail waste phenomenon cause of the pipes adjustment when pipe on production. And the technology of four haul-of unit and cutter have been fused together very wel with the four outlet vacuum calibration tank and spray cooling tankthey can be automatic independent and flexible control to reduce the defective index of fiished products, so as to improve the production efficiency and help customers make more benefit from the new technology.
1. Ensuring long-time stable operation & long service life
2. PVC pipe extrusion machine has compact structure, low noise, high bearing capacity, high transmission efficiency, ensuring long-time stable operation

What types of pipes are typically produced on such line?
Mainly smaller-diameter pipes such as electrical conduits, telecommunications ducts, capillary tubes for irrigation, and medical tubing, where high-volume output of multiple pipes is required.
What are the key advantages over single-cavity lines?
Higher productivity (up to 3–4 times output), lower energy consumption per pipe, space efficiency, and consistent quality across all four pipes due to centralized process control.
How are the four melt streams separated in the die?
Specially engineered multi-manifold die splits the melt into four independent channels, each with precise flow control to ensure uniform wall thickness and dimensions.
How is cooling handled for four pipes at once?
A large, partitioned vacuum calibration tank and cooling tank are used, with internal baffles or separators to maintain even cooling and prevent the pipes from touching or deforming.
How is melt distribution balanced among the four cavities?
Through precision die design (equal flow length channels) and often individual temperature control zones per cavity. Some systems include adjustable flow restrictors for fine-tuning.
How is color consistency ensured across all four pipes?
When using a single extruder, thorough mixing (e.g., with a static mixer before the die) is critical. For critical color matching, masterbatch dosing systems with high precision are recommended.
How do I choose the right plastic extrusion line for my business?
The choice depends on your specific needs, including the type of plastic you will process, the desired final product, required production capacity (throughput), and your budget. A good manufacturer will offer consultation to help you choose the right machine and plastic extrusion line configuration.
How much does plastic extrusion line cost?
The cost can vary significantly depending on the machine’s size, type (single vs. twin screw), production capacity, level of automation, and the inclusion of downstream equipment. It’s important to consider the total cost of ownership, including energy consumption, maintenance, and spare parts.
How do you handle shipping, installation, and commissioning?
We will outline the process for delivery, installation at the customer’s facility, and commissioning to ensure the machine is set up and running correctly.
