Quality policy
—Good Quality, Company-wide Assurance, Keep Improving, Strive for Excellence

As a large energy saving drive, VFD usually applies in important site. Its stable and reliable performance is key to user. Leader&Harvest has been insisting on principle of "quality is first". The company implements quality assurance in terms of technique, design, manufacturer, management and supplier. Meanwhile, Leader&Harvest analyses product fault seriously to reduce the failure. From raw material to mature product, from design to manufacturer, from market research to sale-after service, Leader&Harvest abides by ISO9001 strictly and makes sure quality management system work in effect.

Operation personnel comply with related regulation, drawing, and standard seriously. They take strict control means for important and special work stage to make sure 100% qualification rate.
