There are many types of precision stretching processing techniques, including cold stretching and hot stretching.

Cold stretching is the process of placing a metal blank in a mold and applying external force to stretch and deform the metal, causing it to undergo plastic deformation and resulting in the desired shape and size of the product. The cold stretching process is suitable for processing metal materials such as low carbon steel, stainless steel, aluminum alloy, etc., and can achieve high dimensional accuracy and surface quality.

Hot stretching is the process of heating a metal billet to a certain temperature during metal processing, and then stretching and deforming it to obtain the desired shape and size of the product through the plastic deformation properties of the metal at high temperatures. The hot stretching process can improve the plasticity of metals and reduce processing difficulty, making it suitable for processing materials such as high carbon steel, alloy steel, and copper.

In addition to cold stretching and hot stretching, there are other precision stretching processing techniques, such as multi-stage forming, rotary stretching, deep drawing stretching, etc. These processes can select appropriate processing methods based on specific product requirements and metal properties to achieve better processing results and product quality.

In actual production, the selection of precision stretching parts processing technology needs to be comprehensively considered based on various factors such as product requirements, material properties, and processing equipment conditions. While ensuring product quality, it is necessary to improve production efficiency, reduce production costs, and meet customer needs and market competition. Therefore, in the field of precision stretching parts processing, it is very important to continuously research and innovate processing technology, improve technical level and production capacity.
