Wuxi Mold Factory: What are the reasons for mold wear and tear?

1. Rough machining

   The rough machining strategy needs to be determined based on the type of blank and the surface of the mold. If the blank is a forging or steel part, Wuxi Mold Factory recommends selecting an area for rough machining to remove the model, remove most of the blank edges, and obtain uniform blank edges, which provides convenience for subsequent processing.

   2. Semi precision machining

    The main purpose of semi precision machining is to ensure uniform allowance during processing. The common method told by Wuxi Mold Factory is to first calculate the boundary contour of the residual material (referring to the three-dimensional contour of the unprocessed area of the tool), and then choose a smaller tool to process these three-dimensional contour areas without redesigning the entire model.

   3. Partial organization

   Partial precision machining usually refers to performing clear edge and corner treatments. Transparent angle processing should use multiple processing or a series of cutting tools from large to small.

   4. Organize

   Wuxi Mold Factory suggests that during the precision machining process, unless there is a significant change in the height of the mold contour, parallel precision machining should be chosen.

   What are the reasons for mold wear and tear?

   1. Improper material selection for the main working components of the mold. Wuxi Mold Factory reminds that the material has poor performance and is not wear-resistant; The mold steel has not been refined yet and there are a large number of smelting defects; The convex concave die, forging blank, and forging process are not perfect, and there are hidden dangers in heat treatment.

   2. There are structural design issues and the mold structure is unreasonable. The slender punch is not designed with reinforcement devices, the discharge port is not smooth and piled up, and the discharge force is too high, and the punch bears increased alternating loads.

   3. The mold manufacturing process is not perfect. Wuxi Mold Factory told everyone that the main manifestations are poor internal quality of the convex and concave die forgings, problems with the heat treatment process and technology, resulting in incomplete quenching of the convex and concave dies, soft spots, and uneven hardness. Sometimes microcracks or even cracks may appear without polishing or grinding, and the surface roughness value is too high.

   4. No lubrication or poor lubrication effect.

   The above is the introduction of molds by Wuxi Mold Factory, hoping to be of all help to you.
