Do you know how to increase the corrosion resistance of the piston rod surface?


Piston rods are connecting components used in most mechanical products. However, due to the harsh environments of some mechanical applications, there are also high requirements for their corrosion resistance.

Piston RodIt is a connecting component currently used in most mechanical products. However, due to the harsh environments of some mechanical applications, there are also relatively high requirements for its corrosion resistance. So do you know how to increase its surface corrosion resistance? Let's follow the editor to learn about the methods!
1. Roll-pressing Processing
Through roll-pressing forming, a layer of cold-worked hardening layer is formed on the roll-pressed surface, reducing the elastic-plastic deformation of the grinding pair contact surface, and increasing the generation or expansion of fatigue cracks, thereby improving the surface corrosion resistance.
2. Chrome Plating
After chrome plating,Piston Rodit can have a hard, smooth and corrosion-resistant surface. Therefore, if you want to increase its surface corrosion resistance, you need to chrome plate it. After chrome plating, the coating hardness can reach HV1100, the coating is smooth, the thickness is uniform, the dispersibility is strong, and there is a great improvement in some aspects.
3. Tempering Treatment
Quenching and tempering is to perform quenching and tempering treatment. After tempering treatment, the working strength of the material can be increased, which helps to close the tiny cracks on the surface, hinder the expansion of corrosion, and thus improve the surface corrosion resistance. However, not all piston rods need quenching and tempering, so quenching and tempering treatment should be judged according to the actual situation and materials.
To sum up, this is the introduction of how to increase the surface corrosion resistance introduced by the editor this time. I hope you can learn more through the above introduction.

Summary of Experience with Failed Colin Column Balance Adjustment

Analyzing the causes of errors and summarizing lessons learned during work is an important way to improve work efficiency. Fault case: A Hetian injection molding machine's Collin column broke. The Collin column was replaced and the balance was adjusted, without needing any special tools.


Injection Molding Machine Accessories: Detailed Analysis of Common Temperature Problems!

Injection molding machine accessories. In co-ordinated control, the direction of the temperature sensor in the mold is critical. When placing the temperature sensor, the user must consider its shape, structure, and the direction of the cooling channels. In addition, the temperature sensor cannot be placed arbitrarily; it should be placed in an area that has a critical effect on the quality of the injection molded product. There are many ways to connect one or more high-temperature mold temperature controllers to the controller.


Injection Molding Machine Accessories: Standard Maintenance for Injection Molding Machines

Injection molding machine accessories. Everyone should formulate appropriate daily, monthly, and annual maintenance plans based on the condition of the equipment itself, and carefully implement them for each machine according to the plan. Before using the equipment every day, we should check whether each part of the equipment is normal, such as whether the machinery is working normally, whether the heating conditions of each part are normal, whether the circulating water pipes are leaking, whether the emergency stop button can cut off the motor power supply, etc.


What should be noted when repairing a faulty piston rod?

Piston rod failure is normal. The key is to pay attention to the precautions during specific maintenance. If non-professionals perform maintenance, many problems may arise. If possible, choose professional personnel. Maintenance efficiency and its own use value will be higher. We recommend that everyone should understand the following precautions when understanding piston rod maintenance.


What are some applications of piston rods?

In fact, even if we don't mention it, everyone should know quite a bit about piston rods. Of course, to ensure the efficiency of the piston rod, we must guarantee its performance and quality. If more friends are interested in this field, you can also Tel us to discuss your views, I believe this will be helpful to our work.


Connecting structure of piston rod and piston and how to choose piston rod

Piston rods offer significant advantages in practical applications, and the connecting rod structure of the piston is also unique. When used in combination, it is essential to carefully select hydraulic cylinders that demonstrate good operating and production performance. Such products will be highly reliable. The connection structure between the piston rod and piston, and the manufacturing method of the hydraulic cylinder with this piston rod, are essentially the same.


What does the mold pull rod spacing mean in the injection molding machine parameters?

The actual usable area of the template: the greater the distance between the ejector rods, the greater the actual width and height of the grinding tools that can be accommodated. Because injection molding machines need to install plastic injection molds between the moving template and the fixed template, plastic products can be processed. If the mold is to be installed between the two templates, it must pass through two adjacent ejector rods, so the shape of the mold must be smaller than the spacing between the ejector rods.
