Description

Technical Field

[0001] This invention relates to the field of manganese zinc ferrite production technology, specifically a process method for improving dimensional misalignment in Mnzn ferrite products. Background Technology

[0002] MnZn ferrite E+I type products generally have the problem of misalignment between E and I sheets. Except for the conventional EI (EE+I) type, which can have E and I sheets made in the same mold and does not have this problem, other types such as EQ+I, where E and I sheets are made in separate molds, all have the problem of misalignment between E and I.

[0003] During production, the I-piece size is appropriately enlarged by adding powder during molding. Based on the actual size of the E-piece A, the I-piece A size is then re-ground to ensure that the A size of E+I is within the misalignment range. This method is acceptable if the customer can accept it. However, customers with high requirements for appearance will not allow re-grinding (do not accept re-grinding), because re-grinding the A size will result in different chamfers on both sides or color differences.

[0004] Therefore, in view of this, we studied and improved the existing structure and its deficiencies, and proposed a process method to improve the dimensional misalignment of Mnzn ferrite products. Summary of the Invention
