How to solve the problem of insufficient filling in the process of plastic injection molding

In the process of plastic injection molding, there will be a variety of problems, and insufficient filling is a phenomenon with high probability, so what is the reason for insufficient filling? How should we solve this problem? Mr. Fu, a teacher of Jiangsu injection molding factory for many years, shared it with you.
Plastic injection processing
1、 The main reasons for insufficient filling in plastic injection molding are as follows:
1. Insufficient resin capacity.
2. There was insufficient pressure in the cavity.
3. The […]

Analysis of cooling time in injection molding

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 […]

Causes and solutions of bubbles in injection molding

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 […]

How to solve the peculiar smell of injection molding products

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 […]

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 […]

Suggestions on the installation of injection mold

1. Preparation before installation
Confirm the cooling water channel, and the screw depth into the machine plate is 1.5-1.8 times of the screw diameter. If the screw is not enough, it is easy to slide the teeth, and there is a risk of mold falling. Confirm whether the operators, materials, tools, documents, equipment and auxiliary equipment required for production are complete.
2. Method of lifting formwork
When the hanging die is not horizontal, there will be segment difference between the front and […]
