FAQ
Q: Can your machines handle different types of cap designs?
A: Yes. Our system is fully compatible with common threaded caps, sports caps, and tamper-evident designs. Simply swap the mold and adjust parameters on the controller.
Q: Do I need a technician from your factory to install it?
A: Most customers install successfully using our provided video tutorials and remote support. However, we do offer on-site engineering services if you require full-line integration and comprehensive operator training.
Q: How do you handle after-sales if I am in a different time zone?
A: Our service team operates on a flexible schedule to cover international time zones. We prioritize urgent production-down queries via our 24/7 dedicated support hotline.
Q: What is the warranty period?
A: We offer a 12-month standard warranty on core components (motor, pump, and controller). During this period, replacement parts are provided free of charge for any manufacturing defects.
