011.Differences between I-beams and H-beams 1.1 Differences in Structural Characteristics In practice, the differences between I-beams and H-beams often confuse construction practitioners. Although the two steels are similar in appearance

2026 Large Sheet Metal Parts Processing Quality Brand Recommendation List Technical Professional Orientation I Industry Development Background and Screening Basis According to the "2025-2030 White Paper on the Development of China's Precision Sheet Metal Industry".

What are the design principles and considerations for CNC machining of aluminium enclosures? Aluminium casing CNC machining is widely used in modern manufacturing industry. In order to ensure the processing quality and process efficiency, designers should follow some principles and precautions when CNC machining of aluminium enclosure.

In the field of metal processing, stamping of thin-walled metal parts occupies an important position. However, the thin-walled metal parts stamping process often faces the problem of deformation control. How to effectively control the deformation of thin-walled metal parts stamping processing

The main girder structure of overhead travelling crane will be deformed by various factors in the process of long-term application, and the deformation problem can not be completely avoided, for the deformation of the main girder structure.

Excavator bucket rod upper end cracking reason analysis and improvement,1.Cracking phenomenon of a model of excavator factory work 3000h or so, one after another, the upper end of the bucket rod cracking phenomenon, cracking part is located in the top of the bucket rod reinforcing plate and the bucket rod cylinder piston rod support plate articulation overlap weld at the vertical plate.

In the design of machining process regulations, the development of process routes is the core skeleton of the entire process design, which directly determines whether the parts processing accuracy can meet the standards, high and low production efficiency, manufacturing costs are controllable. Many new craftsmen often make mistakes
