JDF is a big manufacturing company, we focus on quality control:
Raw Material:
We use forged high strength steel, to improve cylinder not only in appearance but in mechanical performance.
Strictly Producing process:
1, Raw Material Process
2, Tempering steel
3, Induciton hardened steel
4, Chrome plating rod
5, Rod finish machining
7, Painted rod
Our CNC Centers:
Rod Heat Treatment:
Piston rods are tempering and hardening by precision control systems throughout entire process for consistent performance.
The material are analysised and evaluated by metallographic examination for quality control.
Welding process :
The welds are done fully automated for consistency and integrity. With lean welding craft for creating the strong joint strength and eliminating the defect.
The welds are detected by certified method like Dye penetrant, Ultrasonic.
JDF can also customize cylinders that just for you
Gland is a part of cylinder components.
Reliable cylinder parts mean better compatibility and longer life more variety and better availabiligy.
Pistion : HIgh pressure piston sealing maerial
Teflon or nylon seals
HIgh precision machining maximize the consistence of parts.
Seal: Stop the leak
Superior quality named-brand seals improve a longer life and seal effect
Polyurethane U-packing rod seals
Bonded-to-metal wiper seals
Teflon or nylon seals
Custom seals available
Rod: The Rod are induction hardened prior to chrome plating, which prevent the rod from bending and scratching.
The rod remain rustless over 100 hours under salt spray test.
Tube : The tube are skived&burnished for the straightness and concentricity, the superior finish bring better sealing and longer life
Turning concept to implement:
Collaborating closely with you, we are all together from concept to implement.
That is why we can provide high efective solutions and improve continually the product performance. whatever your demands may be.
The experience team use the Autocad and Solidworks combining with simulation techniques like FEA to design the most reliable and cost-effective cylinder.
We can also provide 2D or 3D models in Solidworks or other format for your application.
