FAQ

Q: What are the main applications for PET sheets produced by this extrusion line? A: PET sheets from this line are primarily used for thermoforming packaging in food (blister packs, trays, containers), electronics (protective trays, component packaging), pharmaceuticals (tablet blister packaging), and cosmetics industries. The sheets offer excellent barrier properties, transparency, and formability.

Q: What is the typical lead time for delivery and installation? A: Standard delivery time ranges from 60-90 days after order confirmation, depending on configuration complexity. Installation and commissioning typically require 2-3 weeks with technical engineers provided by Jwell Machinery for on-site support and operator training.

Q: Does the line support recycled PET material processing? A: Yes, the twin screw extruder is capable of processing recycled PET (rPET) materials. The system can handle up to 30-50% post-consumer recycled content when properly crystallized and dried. A crystallization dryer is included in the complete line configuration to prepare recycled materials.

Q: What are the power and space requirements for installation? A: Total power consumption ranges from 150-350 kW, depending on line configuration. Recommended factory space is approximately 25-35 meters in length, 5-8 meters in width, and 4-5 meters in ceiling height. Detailed layout drawings are provided during order confirmation.

Q: What warranty and after-sales services are included? A: Jwell Machinery provides a 12-month warranty covering manufacturing defects on mechanical and electrical components. After-sales support includes spare parts supply, remote technical consultation, on-site maintenance services, and periodic equipment inspection programs. Extended warranty and service contracts are available.

Q: Can the line be upgraded for multi-layer co-extrusion? A: Yes, the system architecture supports future upgrades to multi-layer co-extrusion configurations by adding secondary extruders and a multi-layer feedblock. This allows production of APET/PETG composite structures for enhanced barrier properties or cost optimization.
