Product Description
The Corrugated Flexible Draining Hose Making Machine is a single-screw extrusion line for small-diameter single-wall corrugated pipe — the flexible bellows tube that runs inside washing machines, vacuum cleaners, air conditioners, machine tools, lamp wiring and prestressed concrete ducts, and that is bought in bulk as wire conduit and drain hose.
The machine is built around three things that decide whether a corrugated tube line is worth running:
Even corrugation and a clean wall. The forming section uses gears to drive the mould blocks and templates and combines circulating water cooling with air cooling. That combination is what produces high-speed moulding, even corrugation, and smooth inner and outer pipe wall — the three quality points every corrugated hose buyer inspects first.
Small diameters, one homogeneous bellows. The line is designed for PVC, PP and PE small-diameter single-wall corrugated pipe, with the die and the corresponding forming moulds producing a homogeneous single-wall bellows product — no lamination, no seams.
A model for every production speed. The machine is offered in three versions, so the line speed matches the market you sell into:
Normal-speed single-wall corrugated pipe machine — line speed up to 8 – 12 m/min
High-speed single-wall corrugated pipe machine — line speed up to 20 – 25 m/min
Vacuum-type single-wall corrugated pipe machine — used for making pipe with joint
What it produces: corrugated flexible draining hose for wire conduit and cable threading pipe, washing machine drains, vacuum cleaner hose, ventilation pipe, and special tubes for prestressed concrete.
The figures below are transcribed from the manufacturer's published data in two places on the source page: the product attribute panel and the model parameter table. Where the two places state different figures for the same machine, both are shown with their source labelled. They are not merged, and no third value has been introduced to reconcile them.
| Model | Pipe diameter | Extruder | Forming machine length |
|---|---|---|---|
| cx35 | Φ9 mm – 35 mm | SJ45/28 | 3 m |
| cx55 | Φ35 mm – 55 mm | SJ55/28 | 4 m |
| (model code not stated on the source page) | Φ55 mm – 75 mm | SJ65/28 | 4 m |
The extruder designation (for example SJ45/28) is the standard form: SJ for single-screw, the first number for screw diameter in mm, and the second for the screw length-to-diameter ratio, so SJ45/28 is a 45 mm screw running at a 28:1 L/D.

Reading the model figures together. The attribute panel names a SJ65/30 machine as the quoted model, while the parameter table lists the extruder that pairs with each pipe-diameter range — SJ45/28 for Φ9 – 35 mm, SJ55/28 for Φ35 – 55 mm and SJ65/28 for Φ55 – 75 mm. These are two views of the same series: the attribute panel states the machine class, the parameter table states the extruder matched to a given pipe diameter. The extruder, the die and the forming moulds are always specified together for the pipe size you intend to run, and the exact configuration is confirmed in the quotation.
By pipe diameter — Φ9 – 35 mm (cx35, 3 m forming machine), Φ35 – 55 mm (CX55, 4 m forming machine) or Φ55 – 75 mm (SJ65/28 extruder, 4 m forming machine)
By required line speed — normal-speed version at 8 – 12 m/min, or high-speed version at 20 – 25 m/min if you are supplying high-volume conduit or appliance hose programs
By product type — if you need pipe with joint (a corrugated tube moulded onto a socket or fitting), choose the vacuum-type machine
By material — the line is published for PVC, PP and PE, and the attribute panel lists PPR, PE, HDPE, LDPE and LLDPE as suitable materials; the die and mould set is matched to the material and the pipe diameter
By capacity — the quoted attribute configuration is published at 60 kg/h with a 20 m/min production speed and about 30 kW total installed power
The wider catalogue around this machine is described under Single Wall Corrugated Pipe Extrusion Line, Double Wall Corrugated Pipe Extrusion Line, Corrugated Pipe Extrusion Line Solution, Pipe Extrusion Line, Pipe Extrusion Line Solution and Other Type Pipe Extrusion Line Solution.
The published process sequence for the line is:
Material + master batches → mixing → vacuum feeding → material drying → single screw extruder → extrusion mould → corrugated forming machine → meter measure → double winder → finished product inspecting & packing
1. Material dosing and master batch — base polymer (PE granule as published, or PVC / PP) together with colour and property master batches is dosed in the required ratio. Because the colour and the property additives are the same master batch stream, the ratio is set once and repeated.
2. Mixing — the compound is mixed to a uniform blend before it enters the feed system. Good mixing here is what keeps the corrugation wall thickness consistent along the coil.
3. Vacuum feeding — the mixed material is drawn into the machine by vacuum feeding, which keeps the extruder hopper filled automatically and keeps the working area free of powder. Dust-free conveying equipment for the plant can be quoted from the same factory.
4. Material drying — the compound is dried before extrusion. Moisture in the melt shows up as bubbles and a rough inner wall in a thin corrugated wall — drying is a quality step, not an optional one, particularly for PE and for humid climates.
5. Single-screw extruder — the heart of the machine. The extruder is a single-screw machine with a vertical high-torque gearbox, a bimetallic screw and barrel, cast aluminium heating and an intelligent PLC control system with a human-friendly interface. The electrical components are internationally sourced brand-name parts. A high-torque gearbox is what allows a small-diameter screw to be run at the speed a corrugated line needs, and the bimetallic screw and barrel are what give the screw life when running filled or recycled material.
6. Extrusion mould (die head) — the melt is shaped in the die head, which is manufactured as follows:
Mould body: Steel 45#, hardened and polished
Inner mould parts: 40Cr
Calibration bushing: tin bronze (Stannum bronze)
Diameter: can be customized
7. Corrugated forming machine — the tube passes through the corrugating section, where gears run the mould blocks and templates around the tube. The mould blocks form the corrugation profile while circulating water cooling and air cooling set the shape. This is the section that delivers high-speed moulding, even corrugation and smooth inner and outer pipe wall. The forming machine is designed and built in-house on our own machining centre, so the corrugation profile and the mould set are made to the pipe you need.
8. Meter measure — the finished tube is measured by length metering, so each coil or cut length is measured rather than estimated, which matters when the product is sold by the metre.
9. Double winder — the tube is wound by a double winder, allowing continuous production: the line keeps running while a completed coil is changed over.
10. Finished product inspecting and packing — the coils are inspected and packed for shipment.

Working conditions. The line runs as a compact set — feeding system, drying, single-screw extruder, die head, corrugated forming machine, length meter, double winder, and inspection and packing station. The machine requires a levelled industrial floor, a 380 V three-phase 50 Hz supply sized for the about 30 kW installed power, cooling water for the forming machine's circulating water cooling, and compressed air for the plant. The electrical configuration is built as your demand, so a different voltage or frequency is specified at order stage.
