The Process Of CK45 Cylinder Piston Rod Chrome Plating

 CK45 Cylinder piston rod is a very important part in hydraulic cylinder working smoothly,hard chrome plating a piece of precision equipment such as a cylinder rod is a painstaking and methodical process. As one of the leading CK45 chrome plated bar suppliers and manufacturers,DTONG GROUP has been supplying and exporting CK45 hard chrome bar and hard chrome rod for almost 20 years with high quality & good prices.Imperial sizes & metric sizes available.

The Hard Chrome Plating Process:

1. Inspection

The CK45 cylinder chrome rod is inspected during the initial evaluation to determine the condition prior to the chroming process. An inspector will make note of any signs of corrosion, pitting, marring, damage, cracking or flaking. The presence of any of these conditions will be taken into account during the re-chroming process.

2. Grinding & Stripping
Old material on the hydraulic cylinder rod must be removed before new chrome can be applied. This step needs to be completed carefully to preserve the steel beneath the old layer and without affecting the rod diameter. This can be done with two methods – electrolytic stripping and stone grinding.

3. Cleaning and Masking
The hydraulic rod then needs to be prepared to be placed in a bath of chromium solution. Prior to doing so, the rod must be cleaned thoroughly. Undesirable anomalies may occur if debris and contaminants are not properly cleaned during this step. 

4. Plating
Electrolytic plating is a familiar process, being used in a range of applications spanning from plating gold jewellery to applying metal plating to satellites.

5. Surface Finishing
This is a 2-step process of post-grinding and linishing to finish the rods once a new layer of chrome has been applied. The perfect surface finish is achieved by reducing the chrome coating to the exact thickness, and polished.

6. Inspection
For the chroming process of hydraulic cylinder piston rod and induction hardened rod to be complete, the job must pass a final inspection. With ample experience and digital devices for surface thickness and roughness measurement, an inspector checks the quality of the chrome job and ensures there are no defects.

What is a telescopic hydraulic cylinder?

Image
  Telescopic hydraulic cylinders , sometimes called multi-stage cylinders, are a type of linear actuator consisting of a series of tubular rods called sleeves. The sleeves (usually four or five) sequentially decrease in diameter and are nested inside of each other. Once hydraulic pressure is introduced to the cylinder, the largest sleeve (called the main or barrel) is extended first. Once the barrel has reached its maximum stroke, the next sleeve, usually referred to as a stage, begins to extend. This process continues until the cylinder reaches its last stage, called the plunger. There are two different types of telescopic hydraulic cylinders— single-acting cylinders  and double-acting cylinders. Single acting, by far the most common, work by using gravity or some other external force to retract the stages of the cylinder. As soon as pressure is released from the cylinder, the force of the load pushes oil out of the system and the cylinder retracts. While pneumatic telescopic...

WHAT IS THE BEST MATERIAL FOR HYDRAULIC CYLINDER TUBE AND ROD

Image
  An important factor that when manufacturing   hydraulic cylinder tube and rod ,the quality of steel materials.   Datong Hydraulic   work with the best materials for durable, high performance hydraulic cylinder tube and rod. Ideal properties for hydraulic cylinder materials include resistance to wear and corrosion, light weight, machinability, and low cost. Here are some of the most commonly used materials: STAINLESS STEEL TYPE 304 Type 304 Stainless is one of the most widely used materials in  hydraulic cylinder barrel  and piston rod. Type 304 Steel is not only resistant to corrosion but is also easily available and environmentally friendly. Stainless steel 304 is durable in acidic environments and does not wear easily. TITANIUM ALLOY GRADE  When used to manufacture hydraulic cylinders, titanium grade provides corrosion resistance and impeccable strength. It is also easy to machine or form, and is relatively lightweight for its strength - one of the...

How to choose and process hydraulic cylinder tubes properly?

Image
How to choose, process, and install  hydraulic cylinder tubes   properly, in order to make the hydraulic line system work more energy-efficient, reliable, and have a longer life? This has become an important issue for hydraulic technologies. As one of the leading China hydraulic tube manufacturer and supplier,  Datong Hydraulic  specializes in manufacturing hydraulic cylinder tubes and carbon steel honed tube for many years, and has many years experience of hydraulic tube related technology and research. This article will briefly describe the hydraulic pipe selection, processing, installation, etc., with hope to help the customers in the hydraulic system industry who are in need. CHOOSE THE RIGHT MATERIAL AND SIZE OF HYDRAULIC TUBES The hydraulic cylinder tubes should be selected according to the system pressure, flow and application environment. Must pay attention to the strength of the tubing whether is enough, whether the pipe diameter and the wall thick...
