FAQ Q&A Technical Selection Guide
Q1: How to select suitable stamping equipment?
A1: When selecting stamping equipment, the following parameters need to be considered:
STEP 1: Tonnage MatchingSelect a stamping press with an appropriate tonnage based on the material thickness and stamping area. For example, for stamping a 1mm-thick steel plate, it is recommended to choose equipment with a tonnage of over 100 tons.
STEP 2: Accuracy RequirementsFor high-precision stamping parts, a CNC stamping machine equipped with a closed-loop control system should be selected, with a repeat positioning accuracy of ±0.01mm.
STEP 3: Production EfficiencyFor mass production, it is recommended to choose high-speed stamping machines with a stamping frequency exceeding 800 strokes per minute.
Q2: How to extend the lifespan of molds?
A2: To extend the service life of molds, the following operational key points should be noted:
STEP 1: Material SelectionDie materials need to possess high hardness and high wear resistance, such as Cr12MoV steel, which can achieve a hardness of HRC58-62 after heat treatment.
STEP 2: Lubrication and MaintenanceLubricating oil should be applied regularly during the stamping process to reduce friction and wear.
STEP 3: Storage ConditionsWhen the mold is idle, rust-preventive oil should be applied and it should be stored in a dry environment to prevent corrosion.
Detection indicatorsDie life can be evaluated by the number of stamping operations, with high-quality dies capable of enduring over 500,000 stamping operations.
