Plastic Injection Tooling

The quality of finished molds is closely related to the processing mode

1. High machining precision: a pair of molds is generally composed of molds, punches and mold bases, and some can also be multi-piece assembly modules. Therefore, the combination of upper and lower molds, the combination of inserts and cavities and the combination of modules require high machining accuracy, and the dimensional accuracy of precision molds usually reaches level M.
2. Complex shape and surface: some products, such as automobile panels, aircraft parts, toys, household appliances, etc., are composed of a […]

What abnormal problems will injection mold encounter

As we all know, all kinds of tools and products used in our daily production and life, from transportation to buttons and the shell of various household appliances, are closely related to the customization of injection mold. The shape of the mold determines the shape of the product, and the processing quality and precision of the mold also determine the quality of these products. But do you know what abnormal problems often occur in PC injection mold products? So […]

These methods can help you when choosing precision mold manufacturers

At present, the rapid development of industry has gradually taken shape, and the rapid development of precision mold processing has also driven more mold processing factories. How should we choose in the face of so many precision mold processing manufacturers in the market? See below.
1. Learn knowledge in related fields, whether online or paper media collection, find out the core elements in this field and understand the basic knowledge;
2. Understand the specific local conditions of your equipment and search […]

Where does the gas generated during injection molding come from? What are the hazards?

Injection mold is a technical work, and exhaust is also a more important problem, because hot gas is easy to be generated during molding and pouring. If it is not discharged from the mold cavity in time, it is easy to affect the quality of the mold. Therefore, exhaust during injection mold is also a more strict work.
1. Source of gas
(1) Air is left in the mold cavity itself;
(2) Some raw materials contain water that has not been removed […]

Don’t ignore these problems in injection molding

Injection mold is also a processing method, but it is different from other processing methods. It is mainly aimed at some plastic products. However, a few mistakes can easily lead to unqualified finished products. Today, let’s introduce some problems that are easy to be ignored in injection mold processing.
1. Check whether there are signs of wear between the guide column and the guide sleeve after injection molding. If there are signs of scratch, it is caused by lack of […]

Injection mold should consider these three processing technologies

In the process of injection mold processing, the complete professional technology is an indispensable project. It involves transforming plastics into products that maintain the performance of the original system. The important production process design conditions of injection molding are the temperature, pressure and corresponding different effects that affect the plasticization flow and cooling. Here, our analysis can be roughly divided into three aspects: first, temperature and control, second, pressure management and control, and third, forming cycle. There are 3 […]

Several cases of mold deformation

Deformation in the processing of molds and parts is a headache, and it can not be completely avoided. Once a mold or part is deformed in the processing process, there will be losses, and safety problems will be caused. How many cases will the parts or molds be deformed?
1. The internal force changes the machining accuracy of the part. In the machining process, the part is locked by the three claws of the lathe, so that the force on […]

Pay attention to speed and time when machining the mold

On the mold steel with the same surface roughness, the machining speed generated by relative electric pulse during electrode loss is an important factor index to measure the performance of electric pulse machining and machine tool technology products. Generally, in this case, the manufacturer will provide its own processing current to ensure that we can effectively realize the processing speed when the mold is in the processing state. However, in the actual processing design process of life, the processing […]

Exhaust facilities must be set up in the process of injection mold

In the process of injection mold, because the heat is easy to produce hot gas, once there is gas and it is not discharged, it is easy to cause problems in the mold, especially in the rapid prototyping process, once there is excess gas, the mold will bulge, so exhaust is a very important work.
1、 The source of gas in the injection mold.
1. There is air in the casting system and mold cavity.
2. Some enterprise raw materials mainly contain […]

Do you understand the necessity of injection mold trial

Most defects of injection molded products are caused in the plasticization and injection molding stage of injection molded parts, but sometimes they are also related to unreasonable design.
The influencing factors include the type of injection port, the number, position and size of mold cavity, the design of cold / hot runner system and the structure of the product itself. Therefore, in order to avoid product defects caused by mold design, we need to analyze the injection mold during production.
After […]
