Why Partner with Difon?

As a "Specialized and Sophisticated" National High-tech company, Difon Machinery brings following advantages to Hydraulic Motor manufacturing.

Manufacturing Ability: We use 4-axis machining center to manufacture the special internal structure of Hydraulic Motor, "zero burr" quality control for each oil port and valve seat.

Material Reliability: We have spectrometer to make sure material composition is perfect for fatigue resistance, X-ray flaw detection to ensure there is no porosity inside of casting blank, so it will not leak when high pressure.

Digital Tracking: We use CAXA Design System for product design management and ERP system for order management. Based on the technical database established by CAXA system, combined with our ERP system, we track each link of your customized order to make sure 100% traceable and on-time delivery.

Certified Quality：With IATF 16949 and ISO 9001 certification, our quality control philosophy—"Success is built on precision"—is embedded in every machining and assembly process.

Solving Hydraulic System Challenges

Leakage Prevention: Micron-grade machining guarantees perfect sealing surface, minimizing oil leakage for your hydraulic systems.

Wear Resistance: Heat treatment and surface finishing guarantee long service life for internal part of your motor under constant heavy load.

Customization: We are always ready to support your original manufacturer with different mounting flanges or internal splines according to your technical drawing.
