How Are Injection Molded Products Formed?

How are injection molded products formed?

An injection mold is a hollow block of metal into which molten plastic is injected to form a specific shape. The injection mold is drilled with many holes for temperature control through hot water, oil or heaters to ensure perfect molding of the injection molded part.

The molten plastic flows into the mold through the gate and fills the cavity through the runners and gates. The mold is then opened after cooling and the top bar of the injection molding machine then pushes the top plate of the mold to eject the mold.

The injection molded product consists of a gate to introduce the molten resin, a runner to guide the molten resin into the cavity, and the final product.

If only one product is produced in a single injection, the efficiency is very low. Therefore, injection molds are often designed with multiple cavities so that multiple products can be produced in a single shot. In addition, in a mold with multiple cavities, the distance between two cavities and the gate is usually equal. Otherwise, it is easy to have one side filled and one side unfilled.

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.
