A few elements that determine the length of use of a two-material, two-colour mould

The service life of a mould is the total number of productions that the mould can process while ensuring the quality of the product parts processed, and it includes the life of the working surface after several resharpenings and replacement of wearing parts. The following take a look at what factors will affect the life of the double material two-colour moulds?

1. Mould structure

A reasonable mould structure helps to improve the load-bearing capacity of the mould and reduce the thermal and mechanical loads that the mould is subjected to. Reliable mould guiding mechanism can avoid mutual gnawing between convex and concave moulds; cold pier and cold extrusion moulds that bear high strength load can prevent stress concentration through cross-sectional size change processing.

2. Mould materials

Mould life and its material relationship is very large, the greater the number of production, the greater the load on the working time of the material requirements are also higher, for this, should be selected with strong load-bearing capacity, long service life of high-performance mold materials.

3. mould processing quality

Mold parts in the processing, heat treatment process defects will affect the mold life. Such as: mold surface residual knife marks, EDM microscopic cracks, heat treatment of the surface layer of increased carbon powder and decarburization and other lack of goods trapped in the mold's bearing capacity and life brought about by the impact.

4. Mould working condition

Double material two-colour mould in the work, to frequent through the mold, locking, injection, pressure, cooling, opening, ejecting and other processes, in this work process, need to ensure that each work mechanism reliable and light and flexible work, for this reason, need to make the moving parts unhindered movement, and reliable lubrication, require the operator often pay attention to the maintenance and maintenance of the mold, so that it is in good working condition.

5. Condition of the product parts

The surface quality state of the processed parts material, material hardness, elongation and other mechanical properties, the dimensional accuracy of the processed parts, etc. have a direct relationship with the life of the mould. For example: nickel quality fraction of 80% of the special synthetic shape is very easy and mould work surface occurs strong bite phenomenon, so that the work surface bite pull hair, directly affect the mould can work normally.
