What are Cold Pressed and Hot Pressed Saw Blades?

1. Introduction to Cold and Hot Pressing of Saw Blades

Saw blades are commonly used tools in processing materials, and cold pressing and hot pressing are two commonly used processes in the manufacturing process of saw blades. The main difference between cold pressing and hot pressing is the difference in temperature and pressure during production.

2. The difference between cold pressed saw blades and hot pressed saw blades

Cold pressing refers to the pressing process carried out at room temperature. In saw blade manufacturing, there are two commonly used pressing methods: cold pressing and hot pressing.

Cold pressed saw blades are hardened under normal temperature conditions. During the manufacturing process, metal powder is pressed into a binder under high-pressure mechanical action. After a certain formation and processing process, they are formed and processed through multiple processes such as drying and pressing. Cold pressed saw blades have the characteristics of low cost, high hardness, and slow wear, making them suitable for thin cutting and materials with high cutting quality requirements.

Hot press saw blades refer to the pressing process carried out under high temperature conditions, which is commonly used in the production of thick cut materials. Its benefits lie in low cost and high production efficiency, but the manufacturing process is complex and prone to defects and damage. Compared with cold pressed saw blades, hot pressed saw blades have higher wear resistance and stronger adaptability after forming, and are suitable for materials that require higher production efficiency.

3. Application of saw blades

Saw blades can be processed into different materials and sizes through processes such as cold pressing or hot pressing, and are widely used in industries such as construction, wood processing, and cutting. It has the characteristics of high strength, high wear resistance, and smooth cutting, and has a wide range of application prospects in the industry.

In summary, the commonly used processes in saw blade manufacturing, cold pressing and hot pressing, have their own advantages and disadvantages. Cold pressing saw blades are suitable for cutting thin materials with high quality requirements, while hot pressing saw blades are suitable for thick materials with high production efficiency requirements. In daily use, we can choose different saw blades according to actual needs to achieve the best cutting effect.
