Custom Deep-Drawing Stamping Mold For Medical Sterilization Boxes

Stamping die standard parts, as the basic structural units of the die assembly, directly determine the overall assembly accuracy, operational stability, and service life of the die due to their machining accuracy, geometric tolerances, and surface quality. To ensure the interchangeability, reliable fit, and performance of standard parts, a unified machining specification must be followed throughout the entire process to achieve precise dimensions, reasonable fit clearances, and satisfactory surface quality.

Before machining, raw materials must undergo incoming inspection and performance confirmation, verifying the material grade, hardness, specifications, and internal quality to ensure that their mechanical and machinability meet design and usage requirements, and preventing defective blanks such as cracks, porosity, and dimensional errors from entering the machining process.

During the machining stage, it is essential to strictly adhere to the dimensions, tolerance requirements, and standardized process routes specified in the drawings. Key mating dimensions and geometric tolerances must be controlled within the specified tolerance zones. Machining equipment, tooling fixtures, and measuring instruments should be calibrated regularly to ensure stable equipment accuracy. Key dimensions such as locating surfaces, mounting holes, and guide parts must be inspected throughout the entire process to avoid batch deviations.

Surface finishing must meet smoothness requirements, removing burrs, tool marks, and sharp corners, and prohibiting surface defects such as cracks, scratches, and pinholes. Depending on the operating conditions, heat treatments such as tempering, quenching, and hardening, as well as corresponding surface strengthening treatments, should be performed as needed to improve the wear resistance, fatigue resistance, and dimensional stability of standard parts.

After completion, a full-element inspection must be carried out, including dimensional accuracy, geometric tolerances, surface roughness, hardness, and appearance quality. Only parts that pass the inspection can be put into storage or assembled. Inspection data should be uniformly recorded and archived to achieve process traceability and quality control, providing a guarantee for standardized and regulated mold production.
