Plastic Injection Molding

What are the consequences if the polishing time is too long during mold processing

As we all know, plastic mold is an indispensable supporting product in the plastic processing industry. There is also a plastic molding machine, which can make the mold structure better, higher precision and high integrity. However, because the plastic mold processing methods and materials will be different, the type and structure of the mold will not be the same.
In the process of plastic mold, because its polishing steps must also be experienced, but if it is not handled properly, […]

Needless to ask, you can’t see the development trend of injection mold

At present, our industrial application has involved various fields. As long as each industry makes parts, it is inseparable from the mold, because the mold can help them make the desired effect more accurately.
With the rapid development of injection mold industry, a new model based on information. The production efficiency of the injection mold industry has been greatly improved, which has a milestone impact on the manufacturing industry. Due to the organic combination of information related to injection mold […]

What can be done during mold injection to prevent trouble

Injection mold is a craft. It is divided into thermosetting and thermoplastic. According to the molding process, it can be divided into six kinds. Injection molding is mainly the production and processing of some materials with complex shapes. It is mainly to introduce the melted plastic into the material through the injection molding machine, and finally cool it for molding. However, some accidents may occur in this process. In order to avoid accidents, we should do the following work.
1: […]

These contents are the main reasons affecting the machining accuracy of molds

Mold processing designers must have rich experience in design and injection molding. For precision mold processing, the relationship between these factors and injection molding conditions and their apparent factors must be considered, such as injection pressure, cavity pressure and mold filling speed, injection melt temperature and mold temperature, mold structure and gate type and distribution. The effects of gate area, wall thickness, filler content in plastic, plastic crystallinity and orientation are discussed. The influence of the above factors also […]

Don’t be afraid when the mold is deformed

Many molded products need to be processed before completion, so mold processing has become a very popular industry. At present, there are many mold processing and design companies in Guangdong, but the quality is uneven. Do you know the reason why the mold is often deformed? How should we deal with it?
We know that there are many commonly used heat treatment methods. If heating and expansion treatment are still carried out at a very high temperature, it will become […]

The most common methods and processes of plastic mold development and design

Common processing tools and machines for plastic mold development, design and processing
1) Measuring tools: caliper, micrometer, dial indicator, standard gauge block, standard angle block, rotary table, angle gauge, projector, reading machine, etc;
2. Processing machines and equipment: gong machine, lathe, grinder, drilling machine, CNC (computer gong), spark machine, wire cutting machine, etc.
3) Processing method and technology
Generally, the mold is ordered directly from the mold factory, and the processing method is omitted here. According to the processing design drawing of precision […]

In the process of injection molding, we should carefully look at the following four points

In fact, injection mold is a procedure for producing plastic materials, but some attention should be paid to in the injection molding process, because carelessness will deform the materials and make them unusable. And the mold has the nickname of “mother of industry”. It can be seen how important the mold is. Here are four points to pay attention to in injection molding.
1. Good wear resistance. The gloss and accuracy of the surface of injection molded parts are directly […]

Is the injection mold simple? That’s just what you see on the surface

We all think that the structure of the injection mold is very simple, because we only see the surface, but we don’t know that a design is designed to design a mold, but it takes several days to draw a 3D drawing and then convert it into a 2D drawing. During this period, the designer has to go through a lot of tests and judgments when designing each ejector rod, otherwise it will cause the dislocation of the ejector […]

What is the to reduce the use time of precision mold processing?

What are the factors affecting the service life of precision mold processing? Here, Dj molding has sorted out some contents for you. Come and have a look.
1、 The main factor is corrosion failure. When the mold hardness is high, the corrosion resistance is good. If the die hardness is poor, the corrosion resistance is poor.
2、 Thermal fatigue crack damage failure, injection molding and mold are formed repeatedly under the action of cold and heat to form surface and internal […]

How to screen injection mold manufacturers?

With the continuous progress and development of science and technology, the competitiveness of the mold industry is also increasing. For example, in the industry with relatively low threshold of plastic shell injection mold processing, there are many manufacturers with different sizes and small ranges, which makes it difficult for many customers with real demand to find quality manufacturers.
Then Dj Molding will share with you some tips on how to select high-quality manufacturers in many injection mold processing. First of […]
