Currently, many processing manufacturers encounter this problem. After customized injection molding with a thermosetting injection molding machine, some mold fouling may occur. After injection molding of engineering plastics, when we apply various strategies to remove mold scale, we should strengthen the maintenance and upkeep of the mold.
The surface scale of injection molding molds is easy to remove in the early stage, so the mold cavities and exhaust channels are cleaned and maintained on time (such as after each forming production). The mold is not maintained and maintained for a long time, which makes it difficult to remove thick layers of mold scale and time-consuming.plastic spoon machine.
The sprays used for the maintenance of Injection mold construction mainly include: film remover, antirust oil, thimble oil, glue stain agent, mold cleaner, etc.plastic household mold.
The chemical composition of mold scale is very complex, such as general solvents and various unique solvents, oven spray, caffeinated lemon juice, etc. Another unique way is to apply rubber for cleaning model tracks.precision core parts
When Hot runner molding and thermosensitive raw materials are used, the residence time of the solution may be prolonged, thus increasing the risk of mold scale generated by the decomposition of thermosetting materials in thermosetting injection molding machines. Clean the screw of the injection molding machine.household plastic mold.
Using large-sized runners and gates to shape shear sensitive raw materials, multi-point gates can reduce flow spacing, spray rate, and reduce the risk of mold fouling.
Efficient mold exhaust can reduce the possibility of mold fouling, and moderate mold exhaust should be set during the mold design phase. An automatic discharge system or an exhaust method that can easily remove mold scale is an excellent choice, as changes in the discharge system often result in a decrease in mold scale on the mold.servo type injection molding machine.
Covering the surface of the mold cavity with a special non stick coating can prevent the formation of mold scale during the manufacturing of thermosetting injection molding machines. The coating effect should be tested and evaluated. The application of titanium nitride solution on the inner surface of the mold can avoid the formation of mold scale on the mold.
