SUS 420 Pneumatic Piston Rod

Feature:

Material:  This item AHY2-16D pneumatic piston rod is made by high quality material SUS420 and MIM process. After some process testing,  MIM piston rod accuracy would reach +0.05mm. The two key assembly dimension tolerance would promise 0.02mm and +0.05+0.10 mm. The biggest advantage of this air tools spare parts is high-precison, high wearable. You only just send us order and don not make new mould, we could provide you finished items because we have our own professional knowledge and abundant experience.

Surface treatment: vibrate grinding+shot blasting. For this MIM item, the surface is the most important because they are all exposed. Any rusty and irregularity cannot be allowed.

Hardness: 40-45HRC. 420 material is a stailess steel and could do heat treatment, which is the biggest advantage to make tools. Normally stainless steel like 316L 304 do not have hardness or very low about 15HRC. So if you need high wearable items, SUS420 is the best choice. And our No2 machinery company are good at MIM technology.

Advantage: The MIM piston rod of air tools or hand tools could be final shaped for one time and do not need other process. If very precious tolerance, the holes could be drilled. Often we could promise hole 4mm with+-0.03mm tolerance with MIM process.

Why Choose MIM?

♦ Machining free (achieve sharp angle of R ≤ 0.1mm; Depth of Parallelism ≤ 0.02; Ra ≤ 1.6μm; tolerance in ±0.025mm-±0.05mm)
♦ Excellent geometrically complexity ( achieve a hole of 0.4mm, thin wall of 1mm ) 
♦ More than 98% of material utilization rate
♦ Part-to-part uniformity 
♦ More than 95% of theoretical density, and its performance is comparable with forging parts.
