LPG Stamping Molds, Handle, Cylinder Body, And Bottom Stamping Parts

The most common error in mold processing is dimensional deviation, often caused by insufficient precision of the processing equipment or improper operation, directly affecting mold assembly and workpiece quality. This mainly manifests as the mold cutting edge and cavity dimensions being too large or too small, and positioning deviations in guide pillars and guide sleeves. Correction requires first calibrating the processing equipment, regularly checking the precision of CNC lathes, milling machines, etc., adjusting equipment parameters to reduce inherent equipment errors; increasing the frequency of dimensional checks during processing, using calipers and micrometers for real-time measurement, and promptly adjusting cutting speed and feed rate when deviations are detected; and performing secondary finishing to correct any deviations.

Shape errors are also a frequent problem in mold processing, commonly seen in the deformation and tilting of mold cavities and cutting edges, often caused by unrelieved raw material stress or improper heat treatment processes. For example, mold cavity deformation after quenching, or tilting of the cutting edge leading to workpiece skewing. The corrective measures include annealing the mold steel before machining to eliminate internal stress; optimizing the heat treatment process, strictly controlling the temperature and time of quenching and tempering to avoid mold deformation; and correcting deformed parts through grinding and polishing to ensure the mold shape meets design requirements.

Excessive surface roughness and improper assembly clearances are also common errors that require targeted correction. Excessive surface roughness can lead to mold jamming and workpiece scratches. Correction requires selecting appropriate cutting tools, optimizing cutting parameters, and polishing and grinding the mold surface after machining. Improper assembly clearances are often caused by machining errors in parts and non-standard assembly operations. Correction requires strict inspection of part dimensions, replacement of unqualified parts, precise positioning during assembly, and adjustment of the mating clearances of guide pillars, guide sleeves, and other components to ensure smooth mold operation. By minimizing errors in detail, the quality of mold machining can be guaranteed.
