Analysis Of Color Stripes And Color Lines Of Injection Molded Products

Analysis of color stripes and color lines of injection molded products

Although the color masterbatch coloring is better than dry powder coloring and dyeing paste coloring in terms of color stability, color purity and color migration, the distribution, i.e., color particles in diluted plastic in the mixing uniformity is relatively poor, and the finished products naturally have regional color differences. Main solutions.

Stainless Steel Insert Moulding

(1) increase the temperature of the filling section, especially the temperature of the back end of the filling section, so that its temperature is close to or slightly higher than the temperature of the melting section, so that the color masterbatch into the melting section as soon as possible to melt, promote and dilute uniform mixing, increase the opportunity of liquid mixing.

(2) Under the condition of certain screw speed, increase the back pressure to make the temperature of the molten material in the barrel and the shearing effect are improved.

(3) Modify the mold, especially the pouring system, such as the gate is too wide, when the molten material through, turbulent flow effect is poor, the temperature is not high, so it is not uniform, ribbon mold cavity, should be changed to narrow.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
