Hardware stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining workpieces of the required shape and size, including punching, bending, drawing, forming, finishing and other processes. The stamping process and the die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined with each other can stamping parts be obtained.

 

Hardware stamping is not so much an industry as a process, a process widely used in all industries that require stamping, such as automobiles, electronics, furniture hardware, kitchen and bathroom.

 

In the process of precision hardware stamping, some quality problems are often faced. Zhuokai will discuss these common problems in detail and provide solutions to ensure the best quality in the processing process.

 

01. Dimensional deviation

Precision hardware stamping processing usually requires parts to have very precise dimensional requirements. Deviations beyond the allowable range will directly affect the quality of the product. In order to solve this problem, it is first necessary to ensure that the die and mold used have sufficient accuracy and stability. Secondly, it is necessary to strengthen the monitoring and inspection of dimensions during the processing, find problems in time and make adjustments and corrections

 

02. Surface quality

Precision metal stamping processing usually requires that the surface of the parts is smooth, without scratches, burrs and other defects. If the surface quality does not meet the standard, it will directly affect the assembly and use of the parts. In order to solve this problem, it is first necessary to ensure that the stamping equipment and tools are in good condition to avoid damage to the surface of the parts. Secondly, after the stamping process, necessary surface treatments such as polishing, electroplating, metal powder spraying, etc. are required to improve the surface quality.

 

03. Inappropriate material selection and composition

Metal stamping processing usually uses a variety of materials, such as stainless steel, aluminum alloy, iron, zinc alloy, etc. If the quality of the selected materials is not up to standard, or the material composition does not meet the requirements, it will directly affect the strength and performance of the parts. In order to solve this problem, it is necessary to test and screen the materials before processing, select high-quality materials that meet the requirements, and ensure that the composition and performance of the materials are consistent with the requirements.

 

04. Deformation and discoloration

During the metal stamping process, the material may deform or discolor, which is usually caused by the heat generated during the processing. In order to solve this problem, first of all, it is necessary to optimize the stamping process and control the temperature and speed during the processing. Secondly, after the stamping process, necessary cooling and annealing treatments are required to restore the original properties of the material.

 

05. Lax process control

Metal stamping is a complex process that requires strict process control and monitoring. If the process control is not strict, it will lead to instability and unreliability of processing quality. In order to solve this problem, first of all, it is necessary to establish a sound process flow and control standards, and conduct strict quality monitoring. Secondly, strengthen the training and skills improvement of operators to ensure that they are proficient in the operation essentials of each link.

 

Common quality problems in precision metal stamping include dimensional deviation, surface quality, material selection and composition, deformation and discoloration, and lax process control. Solving these problems requires starting from multiple aspects such as equipment, process and materials to ensure that each link meets the best quality standards. Only under fully optimized processing conditions can the high quality and high performance of precision metal stamping be achieved.
