With the development of science and technology, more and more injection molding machine It began to be widely used. Next, we will work with the manufacturers of small injection molding machines to see the steps of operation specifications for injection molding and color molding of injection molding machines:
1、 Characteristics of plastics and parking precautions
Due to the different characteristics of various plastic raw materials, the properties of this glue can be considered when stopping to save time and avoid plastic deterioration.
Methods for plastic products and plastic properties:
PS is hard rubber, with good thermal stability. It will not disperse even if it is heated for a long time. Turn off the electric heating when it stops.
ABS is hard rubber and has good thermal stability. It will not disperse after being heated for a long time. Turn off the electric heating when stopping.
2、 Change plastic and color at the same time
At this time, please select a plastic with similar performance and use it together after adding detergent. General detergents are spiral detergents, kerosene, etc.
3、 Replacement of heterogeneous materials
Thermoplastics adhere to metal surfaces at high temperatures, and do not adhere at low temperatures. The replacement function makes use of this feature to make the material to be replaced attach to the inner wall of the cylinder, which can be replaced with the high viscosity material of the cold screw.
4、 Transformation of the same material
If you want to change the color to the same material, try to change the light color to the dark color, and then change from transparent material to opaque material, which is easier to operate.
When the color changes from thick to thin, from opaque to transparent, and the color is impure after 10 air strikes, remove the nozzle and cylinder head for cleaning.
If the cylinder is not cleaned under this condition, please remove it Small injection molding machine Clean the nozzle and the cylinder head of the charging cylinder. If necessary, remove the screw rod for cleaning.
