Small corrugated tubing can be sensitive to small changes in material feed, die condition, forming alignment, cooling and winding tension. The machine selection should begin with the tube drawing and inspection method rather than an assumed diameter or speed range.
RUNNING MACHINE helps buyers define the fine-tube product, production mix and downstream package so the tooling and control requirements can be reviewed together.
Product details that affect the line
- Resin grade, additives and color
- Outside and inside dimensions
- Wall section and corrugation pitch
- Flexibility and bend requirement
- Slit or unslit construction when applicable
- Coil length, coil diameter and winding tension
- Dimensional, visual or application-specific tests
- Marking and packaging method
Typical equipment scope
A project may include controlled material feeding, a compact extruder, precision die tooling, small-format mould blocks, a corrugator, cooling, guiding, optional slitting, length control and winding. The exact scope depends on the finished tube and the accepted production method.
Control and inspection points
For fine tubing, agree where dimensions will be measured, how profile consistency is checked, how start-up material is separated and how winding tension is controlled. Trial records should link machine settings to the actual resin, tooling and accepted coil.
Information needed for a proposal
- Tube drawing and sample when available
- Resin and formulation
- Full dimension and tolerance table
- Corrugation geometry
- Slit position and method if required
- Coil and package specification
- Target output for the defined tube
- Inspection and marking requirements
- Factory utilities and ambient conditions
Frequently asked questions
Is small diameter enough to select the machine?
No. Wall section, pitch, resin, flexibility, product standard, coil format and tolerance requirements are also needed.
Can several small tube sizes share one line?
Possibly, but each size may require dedicated dies and mould blocks. Provide the product mix so tooling and changeover requirements can be listed.
Why is winding tension important?
Fine flexible tube can be stretched, flattened or presented poorly if downstream handling is not matched to the product. The coil specification should be part of the acceptance plan.
