Third-party testing service
To uphold our standards of excellence through every part of every job, we coordinate quality-approved outside services such as heat treating, electro plating, hot galvanizing, powder coating, anodizing, and painting for our customers.
From design to tooling to production, we can do it all!
Engineering & Designing
Our people are what truly set us apart, strong Engineering and Development is the key to our success. Our team of engineering is a group of highly talented, energetic and service-oriented people with over 100 solid years of combined experience within our field. Some of our engineering capabilities include:
- Provide technical support to all aspects of our manufacturing processes.
- New product development and tooling design.
- Work with clients to meet specific requirements.
Our experts take pride in producing high quality work, having an excellent attention to detail, utilizing innovative designs, and being very responsive to our clients’ requests. Our innovative and flexible approach to design products, with a distinct willingness to think outside the box, allows us to provide clients with solutions that reduce project costs and increase property value, while meeting technical and regulatory requirements.
Tooling Manufacturing
Over 20 years in manufacturing, we have built a solid reputation in design and manufacture of complex mold and tooling for aluminum alloy die casting, metal stamping and machining.
With a quality design by our talented engineers as the foundation, in our fully equipped in-house mold making shop, our team of highly skilled toolmakers is able to build quality mold with the goal of decreasing costs and improving output.
Die Casting
We have 8 die casting machines (from 180T to 900T). Among of them, 350T and 900T machine are from TOYO Japan.
All die casting machines are fully computer controlled. In order to ensure the stability of the housing material, we use spectrometer to analyze and confirm the chemical composition of each furnace of aluminum liquid and use thermocouples to monitor the temperature of the molten aluminum holding furnace.
The first and last piece of each batch of die-casting are cut for metallography examination to avoid inner defect e.g. pin hole and shrinkage and their dimensions are inspected to ensure conformance. Appearance is 100% checked piece by piece during production to avoid visual defects.
Machining
Our precision machining line is committed to achieving the highest quality requirements. DLF has 10 high-precision, high-efficiency, stable and reliable quality machining centers and 19 Japanese Frank CNC.
We strictly control all aspects during machinig, and conduct 100% pneumatic micrometer inspection on each hole for bearing. We measure each of every ten pieces for mounting holes & pin holes, use roughness meter to control the surface roughness of holes for bearing and water seal.
Metal Stamping
Our business started form metal stamping. As a leading producer of metal water pump impellers with over 30 different punch presses equipped to handle capacities from 35 tons to 250 tons, we now manufacture complex, high-quality parts and components for customers both domestically and internationally.
Assembling
Our assembly press is highly computerized and intellectualized with cutting-edge technology e.g. precise locating and automatic alarm etc.
100% leakage test is performed both on water pump housing at the start of the process and the assembly at the end.
