Established in 2009, we specialize in the production of high-quality piston rods and linear shafts, with a focus on precision engineering and advanced surface treatments. Our company's philosophy centers around quality as the core of our business and customer satisfaction as our ultimate goal. With over a decade of experience, we have built a reputation for delivering reliable, durable, and cost-effective solutions to industries such as hydraulic and pneumatic systems, construction equipment, and heavy machinery. **Main Products:** We offer a wide range of products including: - Hard Chrome Plated Rods - Hydraulic Piston Rods - Cylinder Piston Rods - Chromium Rods - Hard Chrome Shafts - Induction Rods and Shafts **Material:** JIS S45C, SAE1045, DIN CK45 Our hard chrome-plated piston rods are manufactured using advanced processes that ensure high precision and durability. The rods undergo precision milling and surface chromium treatment, achieving a surface finish of **f7** and a minimum hardness of **HV800**. This not only enhances wear resistance but also significantly extends the service life of the product, helping customers reduce long-term costs. In-house testing includes salt spray tests to evaluate corrosion resistance. The surface heat treatment ensures a hardness of **HRC 55±2**, with a hardened depth ranging from **0.5mm to 3mm**. The chrome layer thickness is typically **20 microns ±10%**, further enhancing the rod’s performance and longevity. These high-performance components are ideal for use in heavy machinery, construction equipment, and various types of industrial applications. Our chromed steel bars and tubes are widely used in the manufacturing of hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection, and more. --- **Product Specifications Table:** | Item | Hard Chrome Plated Rod | Induction Hard Chrome Rod | |------|------------------------|---------------------------| | Place of Origin | Jiangsu, China | Jiangsu, China | | Material | JIS S45C, SAE1045, DIN CK45 | JIS S45C, SAE1045, DIN CK45 | | Length | 1000–6000mm | 1000–6000mm | | Shaft Diameter | 3–120mm | 3–120mm | | Surface Hardness | Without hardened or hardened | HRC 58–60 | | Chrome Layer Hardness | Above HV800 | Above HV800 | | Chrome Layer Thickness | 15μm ~ 25μm (Customized) | 15μm ~ 25μm (Customized) | | Surface Hardening Depth | – | 0.8–3mm | | Axis Straightness | 0.15mm /1000mm | 0.15mm /1000mm | | Roughness | Ra 0.2μm~0.4μm | Ra 0.2μm~0.6μm | | Precision | G6/F7 | G6/F7 | --- **Chrome Plated Steel Bars** Our chrome-plated steel bars are made from medium carbon cold-finished or hot-rolled steel, typically in grades like 1045. These bars are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005" per side. They are specifically designed for use in hydraulic and pneumatic cylinder piston rods. **Induction Hardened Chrome Plated Bars** These bars are produced using advanced techniques on materials like JIS S45C, SAE1045, or DIN CK45. After polishing and induction hardening, they are chrome-plated to a thickness of at least 0.0005" per side. The result is a highly impact-resistant bar suitable for demanding environments. **Applications:** Linear motion guides, hydraulic cylinder rods, plastic injection molding machines, construction equipment, rubber molding machines, papermaking machines, printing machines, refrigeration equipment, food and chemical machinery, loading equipment, fiber spinning equipment, textile machinery, agricultural equipment, automotive, shipbuilding, and more. --- **Honed Tubes** - **Raw Material:** DIN ST52, SAE1020 - **Pressure & Temperature Classification:** High-pressure & temperature piping - **Inner Diameter:** 40mm–320mm - **Outer Diameter:** 50–400mm - **Thickness:** 5–40mm - **Length:** 7000mm - **Straightness:** Max 0.5/1000mm - **Inside Surface Roughness (Ra):** 0.2–0.4μm - **Tolerance (INT):** DIN2391 H8 **Cold Drawn Seamless Mechanical Tubing (CDS)** This is a cold-drawn 1020 steel tube, produced from hot-rolled bar stock. The cold drawing process improves physical properties, reduces machining time, and provides better OD/ID uniformity, machinability, strength, and tighter tolerances than hot-finished tubing. **Applications:** Hydraulic cylinders, truck and automotive parts, heavy equipment, agricultural components, auto and truck axles, suspension parts, shock absorbers, high-speed shafts, rollers, bearings, spacers, roll cages, and other machined tubular parts. --- **Quality Assurance** We use high-quality raw materials from well-known Chinese brands, ensuring consistent density and stability in our products. Our products are highly appreciated by clients for their competitive pricing and superior quality. **Contact Us:** SUZHOU WEIPENG PRECISION MACHINERY CO., LTD Address: No.98 Changjiang Road, National Hi-Tech District, 215010, Suzhou, P.R.C Tel: 0086-512-68387269 Fax: 0086-512-68387269 Website: [http://www.wepauto.com](http://www.wepauto.com) | [http://www.chromedbar.com](http://www.chromedbar.com) Wishing you a happy new year!

HDPE Resin

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. HDPE is commonly recycled, and has the number "2" as its resin identification code.It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber.
