This article mainly introduces the structure and processing method of plastic handle. Generally speaking, there are four main types of processing methods based on different structures:1. Insert by pressure
2. Injection molding
3. Assembled by rivets
4. Ultrasonic welding
This section will show you the key processes of production, you can see exactly how kitchen knives are made. Knives with different structures have different production processes and manufacturing technology.
The edge of the kitchen knife must be sharp and can be kept sharp for a long time, which can only be done by stainless steel with high carbon content. Therefore, 304 is not suitable for making blades.
The blade materials of kitchen knife are all based on martensitic stainless steel . The mechanical properties of this material can be adjusted by heat treatment, mainly by increasing its hardness and toughness. After more than a decade of continuous efforts, material manufacturers have developed different grades of materials suitable for different product unit prices and users through the research and development and comparison of cutting materials.
