    The influence of plate processing error and bonding gap on the guide posts of the discharge plate
    When manufacturing molds, machining errors between punching plates, discharge plates, and templates, as well as bonding gaps between guide bushings, may affect the deviation of the core when inserting the convex mold. If the convex mold is inserted in this state, it will deform due to misalignment of the core, which may cause the convex mold to break or wear abnormally.Get more news about guide post set manufacturers,you can vist our website!
    The following methods can be considered to address these factors.

    Solution:
    1. Enlarge the hole of the punch guide bushings, but it is not suitable for punching thin plates with small gaps or high-precision molds.

    2.Adjusting the punch guide posts to a nested state is easy to adjust, but the cost is high.

    3. Adjust the mold side to use a pad or shim on the square concave mold to prevent misalignment.

    4. Adjust the deviation of the bonding gap using the reference pin.

    5.Another method is to reduce the gap between the installation hole and the guide bushings. When using high-precision molds without machining errors, it is necessary to prevent misalignment caused by adhesive gaps. In this case, the coaxiality and true roundness of the guide bushings are very important, so please use precision grade guide sleeves. And it is best to use additional DRC to improve the bonding strength.
    There are also methods for pressing the guide bushings, but it is not recommended for high-precision molds because pressing can cause shrinkage of the inner diameter, which can cause deformation and weaken installation strength.
