What are the characteristics of stretching parts
The core characteristics of stretching parts revolve around three dimensions: forming ability, quality stability, and cost advantage. Specifically, they can be summarized into the following four points, which directly reflect their application value in the processing field:
The core characteristics of stretching parts revolve around three dimensions: forming ability, quality stability, and cost advantage. Specifically, they can be summarized into the following four points, which directly reflect their application value in the processing field:
1. Strong molding ability: adaptable to complex structural requirements
It can directly process flat metal sheets into parts with cavities, deep cylindrical shapes, and irregular curved surfaces, such as the deep cavity structure of car fuel tanks and the spiral curved surface of washing machine inner tubes. Compared to welding, assembly, and other methods, complex shapes can be achieved without the need for splicing, avoiding potential strength hazards and leakage risks at the joints.
2. High precision and consistency: suitable for batch precision assembly
By relying on standardized mold production, the dimensional errors and wall thickness uniformity of parts can be controlled (some high-precision parts can be controlled within 0.05mm), meeting the assembly requirements of automated production lines.
Batch products produced with the same set of molds have highly uniform appearance and specifications, without individual differences caused by manual processing, reducing subsequent assembly and debugging costs.
3. High material utilization rate: reducing raw material costs
The stretching process directly utilizes the plastic deformation of metal sheets to form, without the need to remove a large amount of waste like cutting processes, and the material utilization rate can usually reach 80% -95%. Especially for high priced materials such as stainless steel and aluminum alloy, it can significantly reduce raw material waste and lower overall production costs.
4. Excellent structural strength: prolongs the service life of parts
During the stretching process, the grain structure of the metal sheet will be optimized along the forming direction, forming continuous metal flow lines. Compared with spliced or cast parts, it has stronger tensile and impact resistance, and is less likely to break at stress points.
Integrated molding reduces the connection points of parts (such as welds and screw interfaces), avoiding the problems of corrosion and looseness of connection points, especially suitable for parts used in harsh environments such as outdoor and humid environments.
