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 accuracy 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 […]
In the production of some parts or objects with the help of injection molding molds, some products will have unqualified appearance and quality, which is a kind of problem that often occurs in the production process of injection molding. What factors may lead to the poor effect of injection molding products? Now let’s learn about the incentives.
Defects in the shape or quality of injection molded products may be related to the following factors:
1. Physical factors.
When there are bubbles in […]
Model manufacturing is inseparable from high-precision molds, and developers cannot ignore the communication
When developing products or trial producing new products, we should not only focus on R & D, but ignore the communication with the model manufacturing unit. After the product design scheme is preliminarily determined, contacting the manufacturer in advance has two advantages:
1、 It can ensure that the designed products have good forming process and will not be difficult to process and modify the finalized design due to parts.
2、 The mold making personnel can make design preparations in advance to […]
Compared with ordinary molds, precision molds are characterized by higher accuracy of assembly dimensions. Commonly used terms are the processing of some precision instruments, mobile phone molds, etc. Although the volume of precision die is small, its internal structure is very complex, which plays a very important role in the development of electronics, automobile or machinery industries. How exactly are precision molds processed?
What are the stages of precision die processing development
Before precision mold processing, it is necessary to develop […]
In the current industrial production, injection mold helps to improve the production efficiency of enterprises
In the modern industrial system, the extensive application of various new technologies and equipment has played a very important role in improving the production efficiency of the whole society. In this process, the emergence of injection mold largely replaces the shortcomings of traditional mold manufacturing, which plays an important role in improving the production efficiency and economic benefits of enterprises.
The traditional mold is not only cumbersome in the production process, but also needs to spend a lot of time. […]
The cooling time of plastic injection molding products accounts for about 80% of the whole injection molding production cycle. If the injection molding parts are cooled properly, the product quality is qualified. If the cooling is not qualified, it will lead to warpage deformation or surface defects, which will affect the dimensional stability of the products. The injection molding manufacturers analyze the cooling of injection molding parts for you.
The cooling time of injection molded parts generally refers to the […]
In the process of injection molding, bubble is a very common phenomenon, light is harmless, heavy directly affects the actual quality of injection molding products.
1、 Causes of bubbles in injection molding
In the process of injection molding, when the wall thickness of the product is large, the cooling speed of the outer surface is faster than that of the central part. Therefore, with the cooling process, the resin in the central part shrinks and expands to the surface, resulting in […]
Injection molding products are not only required to be qualified in quality, but also have adverse effects on customers if there is a peculiar smell in the produced injection parts. In particular, some injection molding plants use qualified plastic particles, and the increase of peculiar smell will directly affect consumers’ purchase of products. Therefore, injection molding products need to be guaranteed that there is no bad smell.
1. Strictly control the use of additives
The TERT amines used in the production […]
Short shot refers to the phenomenon that the cavity of plastic mold is not completely filled due to the insufficient fluidity of plastic, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance), which is mainly affected by the following aspects:
1、 Injection molding machine
(1) Insufficient injection molding capacity – this is caused by the high capacity of the injection molding machine, which may also be caused by insufficient […]
The automobile industry has developed rapidly in the past ten years, and more and more new products have entered the market, such as new energy vehicles. A large number of automatic parts are made of plastic. As a new material of automobile parts, plastic parts can reduce the weight of automobile and save energy, so they are widely used in automobile industry. This means that a large number of plastic injection molds are needed to produce the required plastic […]
