  • Regularly check the turntable of the punch press and the mold installation base to ensure the coaxial accuracy of the upper and lower turntables.

  • When the punch and die edges of the punch die are worn, stop using them and sharpen them in time. Otherwise, the wear degree of the cutting edge of the die will be rapidly expanded, the wear of the die will be accelerated, and the quality of punching parts and the life of the die will be reduced.
  • HARSLE Stamping personnel should use soft metal (such as copper, aluminum, etc.) to make operating tools to install the mold to prevent the mold from being damaged during the installation process.
  • During the transportation of the mold, it should be handled with care, and no throwing or touching is allowed, so as not to damage the cutting edge and guide of HARSLE stamping mold.
  • To ensure the service life of the HARSLE stamping mold, the spring of the mold should be replaced regularly to prevent spring fatigue damage from affecting the use of the mold.
