Why does the injection molding machine produce coke?
It is a more troublesome thing for the injection molding machine to produce coke material during the production process. These coke materials will inadvertently appear in the joint neck and inside the die head, so that the produced products will occasionally adhere to black spots, Black spots, black lines, what is the cause of the coke material? How should this situation be avoided?
1. The temperature of the machine is too high, or the temperature control instrument fails, causing the plastic to be burnt due to high temperature. Before using the injection molding machine, check the heating system of the machine, and deal with it in time if there is any abnormality.
2. If the heating time is too long, scorching will also occur. Due to the long-term heating of the plastic accumulation, the plastic will age and deteriorate and become scorched.
3. The downtime of the injection molding machine is too long, and the head and screw are not cleaned, causing the plastic to decompose and burn.
4. The head gland is not pressed tightly, and the plastic is aging and decomposed inside.
In order to avoid the occurrence of coke material, it is necessary to regularly maintain the injection molding machine to reduce the occurrence of such situations as much as possible.
