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

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 removal model for rough machining to remove most of the blank edges and obtain a uniform blank edge, which provides convenience for subsequent processing.

2. Semi precision machining

The main purpose of semi precision machining is to ensure uniform allowance during processing. Wuxi Mold Factory tells everyone that a common method 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 select smaller tools to handle these three-dimensional contour areas without the need to redesign the entire model.

3. Partial organization

Partial precision machining usually refers to the processing of clear edges and corners. Transparent corner processing should use multiple processing or a series of cutting tools from large to small.

4. Organize

The mold factory suggests choosing parallel precision machining during the precision machining process unless the mold contour height changes significantly.

What is the reason for mold wear?

1. Improper selection of materials for the main working components of the mold. The 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 melting defects; The convex and concave molds, forging blanks, and forging processes are not perfect, and there are hidden dangers of heat treatment.

2. There is a structural design issue with the mold structure being unreasonable. The slender punch is not designed with a strengthening device, the discharge port is not smooth and stacked, and the discharge force is too large, and the punch bears an increased alternating load.

3. The mold manufacturing process is not perfect. The mold factory tells everyone that the main performance is poor internal quality of convex and concave die forgings, problems with heat treatment processes and processes, resulting in incomplete quenching of convex and concave dies, soft spots, and uneven hardness. Sometimes micro cracks or even cracks may appear without polishing or polishing, and the surface roughness value is too high.

4. No lubrication or poor lubrication effect.
