How to solve the surface defects when processing products

Generally, in mold processing, if we need to use injection molding equipment to process the product surface, there will be large and small defects. Generally, these defects will appear in the gate position, which belongs to the starting position of mold processing, so these two positions are prone to problems, so we need to find ways to eliminate these defects, so that the display effect will be improved.
Dark spot defects and subtle defects will appear near the gate, which […]

What are the reasons for material bending in die processing

In the process of mold processing and customization, there may be a series of situations. In fact, one of the phenomena we will face is the bending deformation of injection mold processing. Then, in the whole processing process, in addition to considering the final requirements or installation, we should also consider the performance of tooling and equipment. In this case, it is necessary to consider more injection mold processing processes. Why is there bending during mold processing?
In the process […]

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, […]

These three knowledge points should be understood before injection molding

1. In depth research and analysis of injection mold structure and related technical development requirements. The structure of plastic parts can determine the complexity of injection mold structure, and the technical enterprise requirements of plastic parts (dimensional accuracy, surface roughness, etc.) determine the difficulty of injection mold manufacturing and molding process. Therefore, for students who do not meet the special educational requirements of plastic injection molding, unreasonable structure and shape, we should clearly put forward the work plan of […]

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 […]

Injection molding and temperature

Mold temperature is an important variable in the injection molding process. A hot mold surface is the plastic surface, which keeps the plastic surface liquid for a long time, enough to form pressure in the mold cavity. For each kind of plastic and plastic parts, there is a limit of mold surface temperature, beyond which one or more adverse effects may occur.
The higher the mold temperature, the smaller the flow resistance. On many injection molding machines, this naturally means […]

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 […]
