What do you need to pay attention to repair mould

2024-12-31

1. Evaluate the degree of mould damage

  • Check the wear condition: Before repairing, first conduct a comprehensive inspection of the mould and evaluate the degree of wear, including the wear of the mould surface, cooling channels, guide devices and other components.
  • Identify damage type: Determine the type of damage to the mould, such as scratches, dents, cracks, corrosion, etc., in order to select the appropriate repair method.

2. Choose the appropriate repair method

  • Surface repair: For minor scratches and wear, the surface can be repaired by polishing, spraying or electroplating.
  • Welding repair: For more serious damage, such as cracks or missing parts, welding repair can be used. Choose the appropriate welding materials and processes to ensure the strength and durability of the repaired parts.
  • Replace parts: For severely worn or damaged parts, consider replacing them directly, such as guide columns, cooling channels, etc., to ensure the normal use of the mould.

3. Pay attention to the selection of repair materials

  • Material compatibility: Choose a repair material that is compatible with the original mould material to ensure that the performance of the repaired mould is consistent with the original mould.
  • Wear resistance and corrosion resistance: Select materials with good wear resistance and corrosion resistance to extend the service life of the repaired mould.

4. Details of the repair process

  • Keep clean: During the repair process, ensure the cleanliness of the mould surface and repair area to avoid impurities affecting the repair effect.
  • Precise processing: When repairing, ensure the processing accuracy to avoid poor mould fit due to improper processing.
  • Heat treatment: For the mould after welding repair, heat treatment should be carried out if necessary to eliminate the internal stress generated during the welding process and restore the hardness and toughness of the mould.

5. Inspection and testing after repair

  • Dimensional inspection: After the repair is completed, a dimensional inspection is performed to ensure that each component of the mould meets the design requirements.
  • Functional test: Before actual production, the mould is functionally tested to ensure that it can work properly and produce qualified molded parts.
  • Record maintenance: Keep detailed records of the mould repair process and results for subsequent maintenance and management.

6. Regular maintenance and care

  • Regular inspection: After the mould is repaired, regular inspection and maintenance should be carried out to detect and solve potential problems in time.
  • Lubrication and cleaning: Keep the mould lubricated and clean to reduce wear and extend the service life of the mould.
