How to understand TZ-machinery CPET RPET PETG APET PET sheet extrusion lines, here we list some ‘ frequently asked questions’ ,it will be helpful to let you know PET sheet production line better.
1. Can you confirm the actual average power consumption of a PET sheet extrusion line during normal production (in kW), rather than just the installed power?
Answer: The actual average power consumption of a PET/CPET/RPET/PETG/GAGPET sheet extrusion line during normal production is 70% of the installed power, calculated as 250 kW × 0.7 = 175 kW.
Normal production actual average power consumption: 175 kW.
2. Does the 250 kW installed power refer to the entire CPET/PETG sheet production line or only the extruder unit?
Answer: The total power of approximately 250 kW refers to the entire sheet extrusion line, including the extruder unit, but excluding water supply and gas supply systems.
3. What energy-saving technologies are used in the CPET/RPET/PETG sheet extruder machine (e.g., VFD, energy recovery systems)?
Answer: The extrusion line adopts high-efficiency energy-saving technologies, such as:
Degassing screw (reduces raw material drying energy consumption for recycled PET processing);
Variable frequency servo drives for transmission components to optimize energy efficiency.
4. Can a CPET/PETG sheet extrusion line be operated efficiently by one operator, or are two operators required?
Answer: The entire line is controlled via an automated PLC control system, allowing one operator to manage production. However, 1–2 additional workers are recommended for sheet packaging and logistics.
Technical and Functional-Specific Questions Of PET sheet extrusion line
5. Does the extruder use a gravimetric or volumetric feeding system for RPET/PETG materials?
Answer: The extruder uses a volumetric feeding system optimized for PETG/RPET/PET sheet production.
6. Is automatic thickness control (ATC) or automatic die adjustment included in the PET sheet extruder?
Answer: Not included; optional add-ons (e.g., ATC for CPET sheets) are available at extra cost.
7. Can the PLC system of the PETG sheet extrusion line be accessed remotely for troubleshooting?
Answer: Yes, remote access is supported for real-time monitoring and updates.
8. Is the extruder screw design optimized for 100% recycled PET (RPET), or only virgin PET/PETG blends?
Answer: Compatible with virgin PET/PETG blends and up to 70% recycled PET content.
9. What safety systems are included in the CPET/RPET sheet extrusion line (e.g., emergency stop, overload protection)?
Answer: Safety systems: Emergency stop, overload protection, pressure monitoring for RPET lines, current monitoring, safety stroke switches, and mechanical guards for high-speed rollers.
10. Is the calender roller gap adjustment for PETG sheets automatic or manual?
Answer: Roller gap adjustment is automatically controlled first, followed by manual fine-tuning for precision sheet thickness.
11. Can the RPET/GAGPET sheet extrusion line’s production capacity be increased beyond 500 kg/h?
Answer: Yes. Upgrading the main motor power can achieve ~550 kg/h for high-output PET/PETG sheet production.
