R&D Excellence

Innovation Forged for Performance

Surviving on Quality, Thriving on Innovation

CLDG specializes in creating innovative forged valve solutions for industries such as oil & gas, chemical processing, and power generation. Our R&D process begins with advanced 3D design, along with finite element analysis and fluid simulations to ensure optimal performance and durability. By managing mold-making and prototyping in-house, we accelerate development and deliver faster, more reliable solutions.

Expert Team with Full In-House Control

Our experienced R&D team manages the entire development process internally—from design and mold making to prototyping and testing. This speeds up new product development and ensures full quality control without relying on outsourcing.

Stronger Production Capacity, Stronger Equipment

Our production plant is equipped with a large number of welding, cutting and machining machines. By increasing the professionalism of our equipment, we make large-scale standardized production more efficient.

Meticulous division of labor, skilled operations and solid technical support ensure that our equipment is delivered within schedule.

Full-Cycle R&D Process

Design, develop, verify—streamlined under one roof.

3D Design & Simulation

We use FEA and fluid dynamics simulations to optimize valve structures and predict performance under extreme conditions—reducing physical prototyping and cutting R&D costs by over 30%, while ensuring long-life reliability.

In-House Mold Development

From design to mold making, every step is completed internally. This enables fast production of complex valve designs, shortens R&D time by 50%, and eliminates outsourcing delays for custom projects.

Rapid Prototyping

Samples are produced within 48 hours for functional testing and design refinement—helping clients launch faster, lower opportunity costs, and avoid design setbacks.

Full-Process Quality Control

We have our own lab with advanced testing tools. During development, we check 100% of steps—like material analysis and sealing tests—to make sure all valves meet API 6D and other global standards.
