Failure analysis of die and solutions

HongChao(DongGuan) Mould & Technology Co.,Ltd. According to the practice of long-term accumulation and a collection of Japanese Daido Steel, Japan's Hitachi Metals, Sweden Uddeholm Tooling steel-related technical data write this column, this column include: mold failure analysis, failure mode of the mold, the mold failure causes, die failure instance, defect analysis tool steel, die steel and other incidents and solutions.

The concept of die failure:
The failure is the mold the mold of the normal loss of ability to work, the production of the products have become waste.

Failure in the form of mold:
The basic form of mold fracture failure (including crack, cracked, chipping, peeling out fast and so on), fatigue, plastic and other shape, wear and tear, bite and so on.
Cold mold common failure in the form of wear and tear, fracture, plastic deformation and fatigue failure and so on.
The use of hot work die environments and conditions are unique, so in addition to cold-working die wear occurs, fracture and deformation of the basic failure modes, but there will be thermal fatigue, thermal subsidence and erosion and other failure modes.
Plastic mold common failure in the form of surface rust and corrosion, surface pitting, wear, cracking and fracture, plastic deformation and fatigue failure and so on.

Die failure of factors:
Mold structure, mold materials, mold heat treatment process, mold machining, mold assembly, mold use and maintenance.

Mold is the "foundation for industrial development", is to increase productivity, reduce production costs, improve product quality and scale of production to adapt to the foundation and guarantee. Analysis and study the reasons for failure of the mold used in order to take appropriate measures to improve the life of the mold, to promote the rapid development of industrial production.
