A shrinkable or extensible corrugated hose is defined by both its manufactured profile and its behavior after compression. The buyer should specify the extended length, packaged length, recovery behavior, end geometry and acceptance tests before the forming and downstream process is selected.
RUNNING MACHINE separates the base extrusion and corrugation steps from compression, cutting, end processing and packing so quotations can be compared on the same finished-product requirement.
Define the finished hose
- Application and installation environment
- Resin or compound
- Tube dimensions and corrugation profile
- Extended and compressed lengths
- Required recovery or holding behavior
- End cuffs, connectors or plain ends
- Cut-length tolerance
- Package format and quantity per pack
- Leakage, flexibility or other acceptance tests
Typical equipment scope
Depending on the product, the line may include material feeding, extrusion, die tooling, corrugation forming, cooling, length measurement, cutting, controlled compression, optional end processing and packaging-related handling. The proposal should identify which operations are automatic and which remain manual.
Compare the full process
Two quotations can use similar extrusion equipment while covering different downstream work. Confirm whether compression, length control, end forming, inspection and package preparation are included, and state the accepted hose condition at handover.
Information needed for a proposal
- Hose drawing and physical sample when available
- Material specification
- Corrugation pitch, dimensions and tolerances
- Extended and compressed length requirements
- End design and connection method
- Required cutting and compression sequence
- Inspection or leakage test
- Target output and package format
- Power, cooling water, air and layout conditions
Frequently asked questions
Is a shrinkable hose the same as an ordinary drain hose?
Not always. The compressed-to-extended behavior and package presentation can require additional downstream operations and separate acceptance checks.
Can compression and cutting be automated?
They can be evaluated after the profile, length tolerances, end condition, recovery behavior and package method are defined.
What should be checked during a trial?
Measure the manufactured profile, cut length, compressed length, extended condition, end geometry and any agreed application test using the specified material.
