How to solve the problem of flow marks on the surface of injection molded products?

Flow mark is a common appearance defect of injection molded products. It will have a great impact on production, so how to solve it? Now let’s talk about how to solve the problem of flow marks on the surface of injection molded products?
Fault analysis and troubleshooting
1. The poor flow of molten material leads to the annual ring shaped ripple flow mark centered on the gate on the surface of plastic parts. It can be adopted to increase the temperature […]

Finishing process of mold manufacturing

A mold is composed of many parts. The quality of the parts directly affects the quality of the mold, and the final quality of the parts is guaranteed by finishing. Therefore, it is important to control the finishing. In most domestic mold manufacturing enterprises, the methods used in the finishing stage are generally grinding, electric machining and fitter treatment.
At this stage, it is necessary to control many technical parameters such as part deformation, internal stress, shape tolerance and dimensional […]

Several characteristics of precision mold processing

The most important thing in precision mold processing is precision. Therefore, the size of the workpiece has high requirements, and the error is about +-0.005. In addition, many precision molds cannot have a slope during production. It is precisely because of the operability and controllability of processing that the whole process can be carried out smoothly. Here are some features of precision mold processing.
1. Abrasion resistance
When plastic deformation occurs in the female mold of the injection mold, the raw […]

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 […]

Injection mold is different from other processing technologies

Injection mold is a technical work, which is different from other processing technologies. When using injection technology, different materials should be selected according to different molds and different injection molding processes should be used. This is the difference of injection mold. There are different regulations on raw materials, characteristics and molds.
1. with the emergence of high-speed forming machinery and equipment, the production speed of plastic products has accelerated. As the injection mold temperature is usually between 165-300 ° C, […]

These three processing technologies should be considered for injection mold

In the process of injection mold processing, the complete professional technology is an indispensable project, which involves the transformation of plastics into products that retain the original system performance. The important production process design conditions of injection molding are the temperature, pressure and corresponding different effects that affect the plasticizing 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 […]

How much do you know about mold design

1. Batch size test, mold production hours, can be made into wood or resin. However, if a die is used to obtain data such as shrinkage, dimensional stability and cycle time, a single cavity die should be used for experiment and can be used in production. Molds are generally made of gypsum, copper, aluminum or aluminum steel alloy, and aluminum resin is rarely used.
2. Geometric design: dimensional stability and surface quality shall be considered during design.
3. Dimensional stability. In […]
