Plastic Injection Molding

Analysis on the origin and development of injection mold processing

Since modern times, all kinds of tools and products, ranging from screws to machinery, have filled people’s daily life, and these products are closely related to mold processing. Mold, as the name suggests, is a special tool used in various presses and installed on presses, and then metal or non-metal materials are made into parts or products of the required shape through pressure. Especially since the new century, plastic products, as a great invention, have been widely used by […]

What is the reason for the wide application of injection molding

In our daily life, we need to use injection molding technology for toys, bottles, containers and other materials we buy for our children. More products we don’t know are manufactured and processed by injection molding industry. Why do so many products use injection molding? It has several advantages.
1. suitable for producing precision products
One of the main advantages of plastic injection molding technology is that it can easily design a complex plastic precision parts and components through teaching. Compared with […]

Key points of molding dimension control for injection mold products

With the rapid development of mold industry in recent years, and the continuous expansion and progress of the application scope of new technologies and processes, there has been a qualitative change from the accumulation of traditional experience to the application of software development.
The wide application of CAD, cam and CAE has opened up a space for the rise of the geometric dimension control technology of our molds and mold products. Due to the great difference in the market demand […]

Which mistakes are easy to make in the injection mold process?

In fact, injection mold engineering is often used to make plastic products. It also uses a technology to make the structure and size of plastic into a workpiece, so the structure and quality of injection molding can directly affect the quality of finished products. What are the problems that are easy to occur in the work of injection mold? Let’s have a look.
1. difficult sprue stripping
In the injection molding process, the grid electrode of the grid electrode is glued […]

Many factors affect the quality of finished products in the mold forming stage

In the process of injection molding, whether the finished product quality and accuracy of the mold meet the requirements is the top priority. The formed mold should meet the requirements of size, accuracy and shape, but the injection molding process will be inconsistent due to the difference between heat and shrinkage, so this process should be handled carefully.
Improper injection mold or design will directly affect the shrinkage of plastics, because the size of plastic products plus the estimated size […]

There are many dents when processing parts. How to prevent them

Generally, various errors will occur in the processing of precision parts or precision molds. Shrinkage and dents are very common phenomena. If dents always appear in the processing of parts or molds, we should pay attention to these. The following precision parts processing manufacturers will tell you how to prevent dents during processing.
1、 Dents in precision parts processing
1. When machining precision parts, if the cooling time is short, the parts will also be deformed;
2. During precision mold processing, if […]

Filling knowledge of injection molding

Injection molding is a step that many molds need to go through. This step is divided into four stages, and filling is the first stage. Here is not to say that filling is more important in the injection molding process. No one can leave who in the four stages. The following is mainly about filling.
First of all, we need to understand that filling is the first step of injection molding. It needs to work at the beginning of mold […]

Why make molds like this?

At present, many equipment need a mold. Without a mold, it will be very troublesome and can not achieve the desired effect. There are more and more mold manufacturers. Each personnel will have their own shortcomings and shortcomings in the design process. The methods summarized by technicians with 20 years of experience are as follows:
1、 Accept the assignment
The task list of plastic molded parts is usually proposed by the part designer, as follows:
1. Some approved drawings shall be marked […]

Design scheme and heat treatment of injection mold

At present, there are more and more plastic products, so there are more and more injection mold enterprises. However, the quality of molds produced by each enterprise is also not the same. Some people have questions. Why is the quality of the same technology and materials very different? Purongni injection mold manufacturer will tell you the reasons here.
In order to avoid similar problems, first of all, after the design scheme of injection molding products is determined, it is necessary […]
