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.

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.
