Quality Control - Ensuring Every Machine Meets Global Manufacturing Standards
Zhejiang Good Machinery Co., Ltd. prioritizes quality control at every stage of production, ensuring our paper cup machines, paper bowl machines, double-walled cup machines, paper plate machines, die-cutting machines, paper food box machines, cup lid machines, flexographic printing machines, embossing machines, and automatic packaging machines meet the stringent standards expected by global customers.
Incoming Quality Control (IQC)
Prior to production, key components such as motors, sensors, and control panels are inspected for dimensional, functional, and technical compatibility.
Precision Assembly by Trained Technicians
All machines are assembled by experienced technicians according to standardized operating procedures to ensure mechanical consistency and long-term stability.
In-Process Quality Control (IPQC)
At each assembly stage, on-site inspectors perform functional tests, torque measurements, and alignment checks to prevent cumulative defects.
Electrical System Testing
PLC systems, wiring integrity, sensor functionality, and safety circuits are tested under simulated operating conditions to verify control system reliability.
Pre-shipment Performance Testing
Each completed machine undergoes an extended, full-load operation test to ensure that output speed, product molding accuracy, and temperature control meet established specifications.
Noise and Vibration Assessment
The machine's acoustic performance and vibration levels are evaluated to ensure compliance with workplace safety standards and customer comfort expectations.
Final Inspection and Quality Sign-off
Before packaging, our quality control team will re-inspect the entire machine according to a checklist of over 30 items, including labeling, appearance, mechanical properties, and documentation review.
Packaging Integrity Check
The machine is packaged in moisture-proof and shock-absorbing materials, and custom reinforced for sea and air transport to ensure it arrives intact.
Customer Acceptance Support
We provide detailed inspection reports, operation videos, and optional remote inspection services, allowing buyers to fully understand the final product before delivery.
