Injection mold gate type and selection-6 Oct 14, 2020
2.2.8 Ring gate The annular gate is arranged on the outside concentric with the cylindrical cavity, that is, gates are arranged around the cavity, so it can be called an outer annular gate, and its gate position corresponds exactly to the inner disc gate . Suitable for thin-walled and long-tube plastic parts. Because the melt of the plastic part evenly enters the cavity around the core, the mold i...

Common problems and solutions for air bubbles in injection molded parts Apr 07, 2021
The thick part of the plastic product processed by injection molding is easy to produce bubbles, and the reason for the formation is exactly the same as that of the depression of the molded product. The cavity formed in the thick wall of the shaped product is a bubble. According to the cause of the bubbles, the countermeasures taken are: when the product wall thickness is large, the cooling rate o...

How to prevent the mold can not be opened? Apr 16, 2021
In order to prevent the mold can not be opened, the following preventive measures should be taken: 1. Calculate the clamping force correctly, not the bigger the better. 2. Do not keep the high pressure mode locking state when the machine is shut down. 3. In case of power failure in the mode locking state, it is necessary to deal with it in time. It is necessary to loosen the crosshead nut after a ...

What are the conditions for AS injection molding? Apr 16, 2021
What are the conditions for injection molding? 1. Pay attention to the design of the formed products if there is the possibility of pot cracking.For special cases, use more than 1° of retraction incline, and pay attention to the mold should not have low sag part. 2. The forming shrinkage rate is about 0.45%, the heating temperature is 170~310℃, the hot air dryer is used, the drying time is 2~3 hou...

The technique method of reducing the shrinkage way in plastic mold processing Apr 23, 2021
The technique method of reducing the shrinkage way in plastic mold processing Shrinkage in the thicker parts of the plastic mold, such as ribs or protrusions, is more severe than in the adjacent areas, because the cooling rate in the thicker area is much slower than that in the surrounding area.Different cooling rates lead to the formation of depressions at the joint surfaces, known as shrinkage m...

The reason analysis that injection molding product cracks? Apr 23, 2021
The reason analysis that injection molding product cracks? When the product is produced, there are cracks, including filamentous cracks on the surface of the product, micro-cracks, top whiteness and resulting in product loss. According to the cracking time, demoulding cracking and application cracking are mainly caused by the following aspects. (1) Processing 1. Increased processing pressure, too ...
