Injection molding process will occur in the process of a variety of problems, burrs is one of the common problems, injection molding process master how to deal with this problem, briefly share the following knowledge content.
A. What is injection molding burr
There are many names for burrs, such as flying edge, overflow edge, overflow material, etc. Different masters have different names, but they all mean the same thing.
Second, the cause of burrs
The occurrence of burrs in the injection molding process is due to the overflow of molten injection resin from the mold parting surface, especially if the burr firmly adheres to the mold parting surface, it will directly damage the mold parting surface, once the mold is damaged, then the injection molding process will produce the phenomenon of burrs, which will also lead to a significant reduction in the life of the mold.
Third, the burr solution
If the burr phenomenon is found to occur, the master of the injection molding process should stop the damage in time, find the cause early and give solutions
1、Do not use too high injection pressure in the injection process
2、Improve the clamping force
3、Adjust the injection volume and lower the temperature
The burr phenomenon will directly lead to the quality problems of the injection molding products, the light ones can be repaired, the heavy ones directly lead to the scrapping of the products, the injection molding production process needs to observe the products in time.
