Quality problems will seriously affect the performance of the extrusion die and the production of related workpieces. Therefore, when the extrusion die is in production, it is necessary to pay attention to the factors that affect its quality problems, so as to prevent the produced workpieces from being used normally. First,Quality of casting materials: Because […]

(1) Metallurgical quality Metallurgical quality has a great influence on the performance of die steel. Only with good metallurgical quality can the various properties of die steel be fully utilized. Metallurgical quality generally includes the following aspects: smelting quality, rolling and forging process performance, heat treatment and finishing performance, thermal conductivity and the degree of

1. Advantages (1) Metal parts with complex shapes, clear outlines, thin-walled deep cavities can be manufactured. Because molten metal maintains high fluidity under high pressure and high speed, it is possible to obtain metal parts that are difficult to process by other processing methods. (2) The dimensional accuracy of die castings is relatively high, up to IT11-13,

Casting can be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process of injecting molten metal into a mould under the action of the earth’s gravity, also called casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting,

The quality of the materials used will directly affect the performance of the mold development and use, so we need to pay attention to the main points when selecting mold materials, so as to avoid the mold does not meet the requirements and cannot be used normally, or the quality of the developed workpiece will

During the use of the Plastic Injection Molds, it is necessary to adopt a certain production line according to the production requirements or technical requirements. Sometimes when some details are not paid attention to, many factors will cause the instability of the mold, which will seriously affect the use of the mold manufacturing workpiece. Therefore, we

Springs account for a very small proportion of the total cost of the mould. Trying to save costs on the springs may cause premature failure of the springs, increase maintenance costs, reduce productivity, make you waste more time and labor costs, and even damage the mould And cause greater losses. How can we ensure the use

In addition to factors such as reasonable mold structure, high manufacturing accuracy, good heat treatment effect, and the correct selection of punches and mold installation accuracy of punches, the service life of the punch die depends on the correct use, maintenance and maintenance of the die. In this regard, the following points should be noted:

In order to improve the performance of the mould, many manufacturers will properly process their moulds. mould processing refers to the processing of forming and blanking tools. In addition, it also includes shearing moulds and die-cutting moulds. However, in many cases, the moulds are processed. It will also reflect processing defects, resulting in a decline

When repairing the mold, we must pay attention to some matters, because the die-casting mold is a very expensive special precision machine, so any failures cannot occur again during the repair. 1. It is all about cleaning up the metal sculpts and deposits in all parts of the mold to show the true color of

In order for the mold to have a reasonable service life, we need to pay attention to some problems when using the new mold, so that it will not cause the early damage of the mold. What problems should we pay attention to when using the new mold? The main attention should be paid to

Common defects in the quality of nickel-tungsten coatings are more pitting, rough coatings on the side and spherical surfaces with white particles, severe unevenness between the central coating and side, corners and R, and even micro cracks at the corners and R. 1. pitting Pockmarks are tiny white and black dot-like defects on the coating.
