How to Cooperate with Us?

01

Pre-sale Consultation

The client provides key parameters and design requirements, such as pump displacement, valve flow-rate specifications, motor torque requirements, pressure-tolerance data, control-mode preferences, and anti-corrosion surface treatment needs. We will conduct a comprehensive evaluation and formulate an initial solution proposal accordingly.

02

Design and Engineering Confirmation

Our engineers create detailed design files based on the client-provided requirements. After the client approves the design concept, we develop a CAD model. Using computer-aided manufacturing (CAM) software, we program the machining process. The generated G-Code precisely guides the manufacturing equipment, ensuring the final product adheres to the engineered design specifications.
