Company Capability
FACTORY SHOW
Established in the year 2009, we company owns modern and standard factory building, including three big workshop. Besides, we have a professional foreign trade team with the aim to export broad range of our products in the international market.

 
EQUIPMENT SHOW
We adopt advanced production technology and first-class processing equipments, such as heat treatment furnace, straightening machine, centerless grinding machine, polishing machine, as well as lathing and milling machine etc.
       
 
 
WORK FLOW

 
Hardening
High-frequency induction hardening guarantees the surface hardness and optimum strength of the material, which makes the shaft highly durable and resistant to abrasion. We can supply several conditions as follows: 
1, Hard chrome plated (surface without heat treatment)
2, High-frequency induction hardened hard chrome plated
3,Quenched and Tempered
4,Induction hardened with Q&T
 
Centerless grinding
Our grinding lines work at high processing speeds with optimum efficiency. Depending on material and diameter requirements, surface qualities with roughness specifications up to Ra 0.2 µm can be obtained.
 
Surface treatment
By hard chrome plating, your components obtain a high resistance to corrosion and wear. This means high endurance over the entire life of the product. Usually, the thickness of hard chrome plating is 10μm ~ 15μm.Resistance in front salt spray (fog) test environment according to the ASTM B-117-97 could be 36 hours.
 
Polishing
We can guarantee you mirror-like polished surfaces with our optimal finish grinding method - without material loss.
 
 
 
PRODUCT SHOW
Backed ourselves with the talented personnel, we have emerged as one of the leading firms indulged in offering superior quality piston rods. The vital parameters of piston rod such as the diameter tolerance, straightness, surface hardness, chrome layer thickness, as well as surface roughness all meet the industry standards.

 
 
PACKAGE
After rigorous inspection, the last important thing is safe packing. Anti-rust oil is to be sprayed on rod surface and each rod is to be packed in paper sleeve and then in wooden box.
 

 
Products
1.Hard Chrome Plated Rod
Quick Details:
Product Features:
The Hard Chrome Plated Piston Rods are fabricated using optimum quality raw material and latest machinery. The bars undergo rigorous processes like pilling, straightening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers. 
Hard Chrome Plated Piston Rods are widely used in hydraulic and pneumatic cylinder, printing machinery, textile machinery, engineering machinery, wood working machinery, etc. Our products are highly appreciated by our clients for their features like corrosion resistance, robust construction, elevated durability, high tensile strength and the mirror-like surface.
  
 
2.Induction Hardened Chrome Plated Bar
Quick Details: 
Product Features:
The Induction Hardened Chrome Bars are fabricated using optimum quality raw material and latest machinery. The bars undergo rigorous processes like pilling, straightening, hardening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers.
Different from the Hard Chrome Plated Piston Rods, the surface hardness of the Induction Hardened Chrome Bars is higher than any other kind of hard chrome plated bars via high-frequency induction technique. The Induction Hardened Chrome Bars are usually used as guide rail or slide rail matching with L.M. Bearing because of the high durability, abrasion resistance, longer working life and dimensional accuracy.

 
3.Quenched and Tempered Piston Rods
Quick Details:
Product Features:
The Quenched and Tempered Shafts are fabricated using quenched and tempered S45C material and latest machinery. The bars undergo rigorous processes like pilling, quenching and tempering, straightening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers.
The mechanical property of the Quenched and Tempered Shafts is better than the Hard Chrome Plated Piston Rods. The Quenched and Tempered Shafts are more qualified under adverse operating environment owning to its excellent mechanical property such as robust construction, elevated durability and high tensile strength.

 
4.SUS 304/303 Stainless Steel Shafts
Quick Details:
Product Features:
The Stainless Steel shafts are fabricated using optimum quality stainless steel and latest machinery. The shafts undergo rigorous processes like pilling, straightening, grinding, polishing and finishing under the supervision of experienced engineers.
Different from Hard Chrome Plated Bars made by carbon steel, Stainless Steel shafts are made by Stainless Steel SUS304 or SUS303 with not hard chrome plated. Stainless Steel shafts have the excellent corrosion resistance performance as well as stainless steel. They are qualified under the condition of acidic, alkaline or high-temperature environment or cleaning and sanitation condition such as food processing machinery.
 

 
5.Machined shafts
We can offer linear shafts with diameter 3mm- 120mm, maximum length up to 6000mm.When you have special requirements on machining, such as threading, axial holes drilled and tapped, radial holes drilled and tapped, milling flutes, reduced shaft diameter etc. we can machine for you. These special machines are finished after heat treatment and hard chromed so that we can ensure the precision of the product. Our service center is at your disposal for machining of shafts according to your request or your drawing. You will be satisfied with our service.
