What factors should the material of the injection mold have?

Do you know the basic principles that need to be achieved when selecting materials for injection molds? If you are still unclear, let's take a look at it with the editor now. 1. Abrasion resistance During the plastic degeneration of the blank in the cavity, the blank flows and slides along the surface of the cavity, causing friction between the surface of the cavity and the blank. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. The main factor affecting wear resistance is hardness. Generally, the higher the hardness of injection mold parts, the smaller the wear and the better the wear resistance. 2. Toughness Most of the researches on the working environment conditions of the mold are very harsh, and some of them are often able to withstand large impact loads, which can lead to brittle fracture. In order to prevent sudden brittle fracture of mold design parts during work, the mold must have relatively high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and microstructure of the material. 3. Fatigue fracture performance In the development process of mold design work, under the long-term influence of cyclic stress, it can often lead to fatigue and fracture of students. Its forms include small energy fatigue fracture through multiple impacts, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.

Which time period is better for custom injection molds?

When is it better to start customizing injection molds? What preparations should be made in advance? The editor believes that we should try our best to do a good job in the preliminary work of product patent applications at each product exhibition in the first three months. In a highly competitive business environment, intellectual property protection has reached a sacred and inviolable level. Otherwise, no one would be willing to invest heavily in scientific research and innovative products, because to innovate products, they must invest in molds, that is, customized injection molds. Before customizing an injection mold, a product plan must be conceived, the product appearance design and functional structure according to the plan idea, and the 3d structure drawing file of the product must be drawn, and a set of 3d samples must be printed according to the 3d drawing file. Generally speaking, it takes 45 to 60 days to complete a customized injection mold, two months, and another month to complete product assembly and functional debugging.

How to control the time of injection molding

In the process of injection molding processing, the time control system is very important, it will affect the quality of the entire finished product of the enterprise. In order to do a good job in injection molding processing, in addition to skilled operations, it is also necessary to have the ability to control the processing time. Because if there is no time to control some research steps, we may find that there are many problems in the product information produced. So in what areas should we control the time?

Several categories of mold manufacturing

Plastic mold manufacturing refers to tools that are matched with plastic molding machines to give plastic products a complete structure and size. There are many types of plastics, and there are many processing methods, so plastic mold manufacturing is also diverse.
