Our mission

• meet and exceed customer expectations
• Prevention and control of nonconforming product
• Optimization of manufacturing processes
• Lowest damage

New Project

When producing spare parts for a new program we will preliminary spare part sampling . As parts move to the production stage,we will conduct input process inspection.Then conduct inspection before shipment.As follows:

Control Plans

• Incoming Material Inspection
• Preliminary part sampling
• Input process quality control
• Outgoing quality control
• Process Flow Charts

Quality Management

Our Machinery and Equipment maintenance ,Calibration of inspection tools, process flow continuous improvement systems have allowed us to move closer to our goal of lowest damage.

Jiesheng hardware utilizes the most advanced inspection equipment and methodologies to ensure the lowest damage possible.Depending on the customer requirements and the complexity of the component, Jiesheng Hardware(Jeasnn) will utilize many quality tools such as:
