Requirement And Solution

What the customer needed to produce, and the line we configured to get there.

THERMOS Tumbler Straw Extrusion Line Project
Requirement

What The Customer Needed

THERMOS required a compact and reliable reusable straw production line for manufacturing:
1. LLDPE straw: 8 × 6 mm
2. PCT straw: 8 × 6 mm / 9.5 × 7.5 mm
3. Output capacity: 10–40 kg/h
4. Stable small tube extrusion
5. Accurate cutting length
6. Smooth chamfering and V-shape opening
7. Suitable for indoor production with continuous operation
The customer needed a complete small diameter tube extrusion line from material feeding to extrusion, cooling, haul-off, cutting, chamfering, and opening.

Solution

What We Supplied

QTech-Machinery provided a complete LLDPE and PCT straw extrusion line customized for reusable tumbler straw production.

The solution included a precision servo single screw extruder, vacuum cooling calibration tank, servo haul-off cutting machine, manual chamfering machine, manual opening machine, and industrial chiller.

This complete plastic tube extrusion line helps THERMOS produce high-quality reusable plastic straws with stable dimensions, smooth surface quality, and efficient downstream processing.
