Main Factors Affecting Life of Dies for Daily Necessities Mould

           Daily Necessities Mould(FURNITUREMOULD) Die life refers to the total number of pieces that can be processed under the premise of ensuring the quality and output of the parts processed. It includes the multiple repairs of the cavity and core surface and the life after replacement of the wearing parts.

The daily necessities moulds are also in the form of normal damage. For the mould surface, the damage forms include friction damage, plastic deformation, cracking, fatigue damage, and bruises. It is generally required that the design life of the mould should be determined according to the production yield of the corresponding parts of the mould at the mould design stage.

The main factors affecting the life of daily necessities mould are as follows:

1) Mould structure. A reasonable mould structure helps to improve the load carrying capacity of the mould and reduce the bearing capacity and mechanical load. The reliable mould guiding mechanism can avoid mutual stab between the punch and the die; the cold pier and the cold extrusion die subjected to high-strength load can prevent stress concentration by the cross-sectional size change treatment.

2) Mould steel. The mould material should be selected according to the output and appearance of the manufactured product. High-performance mould materials with strong bearing capacity and good fatigue resistance should be selected for large production batches.

3) Quality of mould processing. Defects in the processing and heat treatment of mould parts affect the life of the mould. For example, the residual knife marks on the surface of the mould, the microcracks in the EDM, the surface carbonized powder during heat treatment, and the decarburization of the decarburization all have an impact on the bearing capacity and life of the mould.

4) The working state of the mould. When the mould is working, the accuracy and utility of the equipment, the lubrication conditions, the pretreatment state of the processed materials, the preheating of the plastic mould, and the cooling conditions all affect the life of the mould.
