In the stamping process of the die, sometimes it is inevitable that the processed parts will be damaged. How to prevent damage to the stamping parts of the mold? 1. The models, specifications and functions of the hardware fittings should conform to the current national standards and relevant regulations, and match the selection of plastic […]

When the above-mentioned defects occur in the mould parts, qualified fastener products cannot be formed, which will inevitably affect the production plan of the enterprise. Precaution In order to prevent early failure of the mould and effectively extend the service life of the mould, corresponding preventive measures are mainly taken from the following aspects. 1.

Cold heading mould is the most important process equipment in cold heading production, and it is the basis of cold heading processing, which directly affects the quality, production efficiency and safety status of cold heading special-shaped products. The basic composition of the cold heading die: the cold heading die is mainly composed of a feeding

Moulds have high requirements for materials, so the performance of mould materials should have the following points. 1. High wear resistance, if the mould is not wear-resistant, it is easy to cause excessive wear on the cavity. 2. High corrosion resistance, many plastic additives, such as flame retardants, and even the chemical action of the

Drawing moulding refers to a plastic forming method in which the processed material is reduced in cross-sectional area through a mould with a certain taper hole. Various geometric cross-section profiles can be formed through drawing moulding. It is an important method for preparing wires and pipes. . The characteristics of drawing processing are: it is

Because the failure of the drawing die is mainly adhesive wear and abrasive wear, and mainly adhesive wear. Therefore, the selected mould material must have high wear resistance and anti-adhesion performance, and sufficient strength. The selection should also consider factors such as the thickness of the sheet material to be drawn, the size and shape

What are the characteristics of precision mold manufacturing: 1. Wear resistance When the blank is plasticized in the mold type chamber, the surface of the cavity is flowing and sliding along the surface of the cavity, causing a severe friction between the cavity surface to the blank, causing the mold to fail due to wear.

The quality of cold work moulds will directly affect the quality of their products. The life of the mould determines the production cost and economic benefits of the parts. There are many factors that affect the cold work mould. Therefore, the failure modes of cold work die are also various. According to actual production experience,

Extrusion honing: also known as abrasive flow processing. This process method uses a semi-solid abrasive abrasive. Under the action of the extrusion honing machine, the abrasive reciprocates on the surface of the machined part, and affects various parts. A new type of process for grinding and polishing the cavity, cross-aperture and edges, and deburring the round

There are five plastic blow moulding methods: extrusion blow moulding, injection blow moulding, stretch blow moulding, multilayer blow moulding and foam blow moulding. The process of blow moulding products is generally: the preparation of raw materials and the production of i-shaped blanks for transportation. The i-shaped blanks are inflated, moulded, and cooled. Once the moulding method
