Material selection and quality: The quality and thickness of the material will affect the quality of the product after sheet metal processing. In the selection of materials, should consider the tensile strength, compressive strength, stiffness, toughness, hardness and other performance indicators.

Accuracy and stability of equipment: Equipment accuracy and stability have a great impact on product quality. For example, in the secondary bending of sheet metal bending, it is necessary to consider factors such as the springback of the material and the accuracy of the equipment.

Operator skills: The skills of sheet metal processing operators will not only affect the processing efficiency, but also directly affect the quality of the product. For example, the operator should master the strength and balance of the material in the process of bending and manual punching, so as to avoid product deformation or damage.
