Material Of Hollow Piston Rod The selection of materials for hollow piston rods should comprehensively consider strength, stiffness, wear resistance, corrosion resistance, and processing performance. Common materials and characteristics are as follows: 1、 Carbon steel and alloy steel: a balance between high strength and economy 35 steel, 45 steel seamless steel pipe Application scenarios: General hydraulic cylinders, air cylinders, shock absorbers, etc., suitable for medium load, non corrosive environments. Performance characteristics: After quenching and tempering treatment, the hardness of 45 steel can reach 229-285HB, and the surface hardness after high-frequency quenching can reach 45-52HRC, significantly improving its wear resistance. 35 steel has a lower cost, but its strength is slightly inferior to 45 steel, and it is commonly used in light load scenarios. Processing technology: quenching and tempering after rough machining, chromium plating (0.03-0.05mm) on the surface t...

Piston Rod Processing Technology Using rolling processing, due to the residual compressive stress left on the surface layer, it helps to close small cracks on the surface and hinders the propagation of erosion. Thereby enhancing the surface corrosion resistance and delaying the generation or expansion of fatigue cracks, thus increasing the fatigue strength of the oil cylinder rod. By rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the decrease in surface roughness value can improve the fitting properties. At the same time, it reduces the friction damage to the sealing ring or seal during the movement of the cylinder rod piston, and increases the overall service life of the cylinder. Rolling technology is an efficient and high-quality pr...
What Is A Metal Forming Machine In modern manufacturing, metal forming machines are foundational equipment designed to reshape metal workpieces through *plastic deformation*—a process that alters material geometry without adding or removing material. Unlike subtractive methods (e.g., machining) or additive processes (e.g., 3D printing), metal forming leverages mechanical force, heat, or pressure to mold metals into precise, durable shapes. This technology is indispensable across industries such as automotive, aerospace, construction, and consumer goods, where it enables high-volume production of components ranging from automotive body panels to aerospace turbine parts. This guide defines metal forming machines, details their core principles, types, processes, applications, and selection criteria. 1. Core Definition & Operating Principle A metal forming machine is specialized equipment that applies controlled force (mechanical, hydraulic, ...
How To Choose A Pneumatic Forming Machine In modern manufacturing, pneumatic forming machines—which use compressed air to apply controlled force for material shaping—are valued for their speed, precision, and gentleness with delicate materials. From automotive component production to electronics miniaturization, these machines excel in applications requiring consistent pressure delivery and rapid cycle times. Selecting the right model, however, requires aligning its technical capabilities with your production goals, material properties, and quality standards. This guide outlines a systematic approach to evaluating pneumatic forming machines, covering key criteria, machine types, application适配, and implementation best practices. 1. Core Definition & Operational Advantages A pneumatic forming machine converts compressed air (typically 6–10 bar, regulated via valves) into linear or directional force to deform materials (metals, plastics, com...
What Can I Do With A Vacuum Forming Machine Vacuum forming machines are versatile thermoforming tools that shape thermoplastic sheets into precise, repeatable forms by leveraging heat and vacuum pressure. Unlike injection molding (high-cost, high-volume) or 3D printing (low-speed, small parts), vacuum forming balances affordability, speed, and scalability—making it indispensable across industries from packaging to aerospace. This guide details the core capabilities, industrial applications, material compatibility, and integration with complementary manufacturing processes (e.g., metal forming) to help you maximize the value of a vacuum forming machine. 1. Core Principles of Vacuum Forming Before exploring applications, it’s critical to understand the machine’s operational framework—this explains its strengths (e.g., rapid prototyping) and limitations (e.g., deep-draw constraints). The vacuum forming process follows four sequential step...
