PLN 65/25
Single-Screw Extruders
Single-screw extruders of the PLN series are designed for processing soft PVC and TPE and are used in the production of:
- seals
- harpoon profiles
- inserts
- irrigation hoses
- furniture edging
- various profile products
Thanks to the improved screw and barrel design, the extruders provide:
The extruder features a modular design and consists of standardized units:
- High processing efficiency
- Stable and uniform output
- Low noise level
- Long service life
The extruder features a modular design and consists of standardized units:
