Three main reasons for dimensional changes of injection molded parts during processing

No matter what kind of plastic is, it has a certain shrinkage rate. If it is not controlled properly, it will directly lead to the change of the size of the injection molded parts. If the change is too large, it will directly lead to the unqualified quality of the injection molding products. This is a period that many injection molding factories do not want to see, and the three major factors affecting the dimensional change of injection molding […]

Influence of high temperature on injection molding parts in injection molding

In the process of plastic injection molding, too high or too low temperature will have adverse effects on the injection molded parts, which will directly lead to the scrap of the molding parts. Therefore, the temperature control in the injection molding process is very important. What are the specific adverse effects of too high temperature.
 
1. Too high a temperature will reduce the viscosity of the oil
When the temperature of injection molding is too high, the viscosity of the oil […]

What are the causes of product cracking in precision injection molding

For precision injection molding, sometimes in the injection molding, the cause of cracking of injection molding parts will be found, and the final result is the scrap of injection products. So what are the reasons for the cracking of precision injection molding? Injection molding manufacturers to share.
 
1、 Precision injection mold
1. The ejection should be balanced, such as enough ejector rod number and cross-sectional area, so as to prevent the injection molding parts from cracking due to the concentration of […]

Five reasons for shrinkage of injection mold products

No matter what injection molding products, it is inseparable from the injection mold, but sometimes the injection mold shrinkage phenomenon, so what are the reasons for the injection mold shrinkage.
1. Thermal expansion and cold shrinkage of plastics
In the process of plastic mold molding, it is necessary to melt the plastic raw materials. At this time, the melting temperature reaches 200 ~ 300 degrees, and the plastic raw materials are heated to expand. However, in the cooling process of the […]

What should be paid attention to in the use of injection mold

The quality of injection mold directly determines the product quality, performance and production efficiency of injection molded parts. Therefore, in the process of injection molding, it is necessary to pay attention to the production status of injection mold, so as to avoid the problem can not be solved in time and affect the quality of injection products.
Injection molding parts processing
1. Check the condition of injection mould in time
If in the process of using the engineering plastic mold, some abnormal […]

What is the function of injection toner

Injection molding factory in the production of products, injection molding process, need to add toner, so what is the role of adding toner? What should be paid attention to when adding, so as not to affect the quality of injection molded parts.
Injection molding parts processing
1、 Why add toner to injection molding
Plastic Toner is a kind of industrial material. To understand it simply, it can make all kinds of plastic products into any kind of color products.
At present, it is […]

How to judge the quality of injection molded parts

Injection molding products are now everywhere in our life. There are precision injection molding parts and ordinary quality injection molding parts. Injection molding products will become more and more popular in the future. How to judge the quality of injection molded parts? The editor of injection molding manufacturers shares the following.
Injection molding parts processing
1. Dimensions of injection molded parts
In the production and processing of injection molded parts, the size must be consistent with the design drawing, and the accuracy […]

Is the injection product cracked again? This article teaches you to deal with cracking easily

In our injection molding, due to various factors, we often see some uncomfortable cracking after molding, which often makes us feel headache. So today, let’s talk about how to deal with the cracking of plastic parts.
Cracking includes filamentous cracks, microcracks, white top, surface cracking of parts, or trauma crisis caused by sticking parts and flow channels. According to the different cracking time, cracking can be divided into demoulding cracking and application cracking. There are three main reasons
Processing reason:
(1) If […]

How to prevent shrinkage fluctuation of precision injection molding products?

Precision injection molding must be based on the premise that the mold can be made according to the required size. However, even if the mold size is fixed, the actual size of the product varies with the actual shrinkage. Therefore, the control of shrinkage rate is very important in precision injection molding.
Whether the mold design is appropriate or not determines the shrinkage rate, which also varies with different resin batches. If the pigment is changed, the shrinkage rate will […]
