MCCB Highlights
In order to ensure the product quality, we check the leakage and make up for defects, and ensure the product quality, after the completion of welding, ultrasonic nondestructive testing, metallographic testing of welds, tensile testing, shear force testing and other means are used to comprehensively cover the elements of weld joint identification, and the quality risk of each period is strictly controlled through the first inspection, process inspection, completion inspection, factory inspection and other control means to ensure that the product leaves the factory with zero defects.
Workshop welding equipment adopts medium frequency power supply, servo motor pressurization, automatic pressure detection display and automatic defect alarm, ensuring zero defect requirements for products.
Frequently Asked Questions
What testing methods are used to verify MCCB weld quality?
After welding, we utilize comprehensive methods including ultrasonic nondestructive testing, metallographic testing of welds, tensile testing, and shear force testing to fully cover and identify all weld joint elements.
How is the quality risk controlled during the manufacturing process?
Quality risks are strictly controlled throughout every production phase using a multi-step inspection framework, which includes first inspection, process inspection, completion inspection, and final factory inspection.
What advanced features does the workshop welding equipment include?
Our welding equipment is equipped with a medium frequency power supply, servo motor pressurization, automatic pressure detection display, and an automatic defect alarm system to prevent errors.
What is the target defect rate for MCCB products leaving the factory?
Our stringent quality control processes and automated alarm systems are designed to ensure that all products leave the factory with zero defects.
How does the automatic defect alarm system improve MCCB production reliability?
The system automatically monitors pressure limits and detects anomalies in real-time, instantly triggering alarms for defects to prevent faulty hardware parts from moving to the next stage.
