Foam Mould

There are many factors affecting the quality of precision mold fittings, such as the type and quality of die-casting machine, the geometric structure of die-castings and the reasonableness of technical requirements, the structure of the mold and the technical level of the operator. In the case of certainty, the cutting allowance can be left less, in order to help extend the life of high quality precision mold fittings tool. The following is a detailed introduction to what factors affect the quality of precision mold fittings?

1, the rationality of the design of accessories

Designer should first fully understand the user's use requirements and working conditions, die casting force, and then according to the use requirements and working environment to choose the right material, understand its material die casting performance. In the design of precision mold parts, should pay special attention to meet the premise of the use requirements, as far as possible to make the die-casting structure is simple. Wall thickness is appropriate and uniform, and leave the necessary mold slope, otherwise it will lead to the casting on the pit, porosity, shrinkage, under pressure, stretch marks, cracks, deformation and other defects. Requirements for the casting dimensional accuracy should be reasonable, otherwise it will bring unnecessary trouble to the mold design, mold processing, process conditions development and management, and will result in a large number of unqualified products.

2, mold structure, processing accuracy and mold material selection

Die casting is by die casting, mold design, processing, mold material selection and other product quality is closely related. Mold structure is unreasonable, precision mold parts no matter what measures taken from the process, it is difficult to make products qualified. In addition, heat-resistant and wear-resistant precision mold fittings of mold materials, mold processing accuracy, surface roughness, processing traces, heat treatment of small cracks, nitride layer thickness and mold assembly, etc., will affect product quality and mold life.
