How to Control the Highest Casting Quality

01 Raw Material Control

For materials such as 304 stainless steel, suppliers provide their own material analysis reports. We then take samples and confirm the elemental composition of the materials using a benchtop spectrometer. Material analysis is performed after each batch of castings to ensure that customer requirements are met. All raw materials, once confirmed through production, are not changed suppliers to ensure quality stability.

02 Pre-Job Training

We provide training for employees before they start work, helping them develop good work habits and ensuring they strictly adhere to operating procedures to reduce errors.

03 Testing and Inspection

Our testing center has a benchtop spectrometer and metallographic analysis instruments, capable of performing PT and flaw detection tests according to customer needs. Professional inspectors inspect every casting. We retain samples and test bars for customers for one year, during which time you can request to view your samples or test bars at any time.

04 Process Control

We have very strict requirements for both internal and external quality. Each group has a designated group leader with assigned responsibilities; the materials for each furnace are analyzed; and the flow channels of each impeller are checked with a flashlight to ensure they are perfect.
