Injection molding is a process of polymer, which is considered to be a great scientific invention, because it helps to shape plastic into useful products. The injection mold company briefly introduces the following texts, and hopes that everyone can quickly understand the injection molding process. Injection molding is a low-cost technique for creating plastic parts that are both simple and complex.

The operation of the injection molding machine is that the granular plastic enters the heating barrel from the hopper by gravity, a spiral plunger slowly moves the particles forward, the plastic is forced into the heating chamber to melt, the plunger advances, and the molten plastic is forced into the mold through the nozzle, allowing It enters the mold cavity, the mold cools, and the plastic solidifies in the mold. Injection mold parts are widely used in aerospace, automotive, engineering prototypes, hydraulics, pneumatics, packaging, construction, electrical, fiber optics, medicine and dentistry, power tools, agriculture, electronics, physics, measuring instruments, communications, caps, accessories, valves , toys, levers, cameras, etc.

The injection molding commodity economy is a good form, but the injection molding efficiency is different, the quantity is different, the small plastic injection moulding quantity is the most ideal, the simple machine can be completed, the injection molding is a tens of billions of dollars of industry, and 32% of the plastic is processed by injection molding. The formation, the cheap and sustainable injection molding has become the choice of many consumer goods and industrial projects, which has a profound impact on modern society.

What is the plastic mold gate?
What is the plastic mold gate? The plastic mold factory below will tell you in detail that the gate of the mold is also called the feed port, which is the melt passage of the splitter and the cavity on the mold. In the location where we design the gate and the choice, it has a very important influence on the mold, and even directly relates to whether the plastic parts can be finished and produce high quality products.

In our mold industry, gates can be divided into non-restrictive gates and restricted types. The main function of the non-restrictive gate is to apply pressure to the cavity after the introduction and feeding to prevent the injection molded article from generating flash. Through the change of the cross-sectional area of ​​the gate, the plastic melt flowing through the runner must increase the injection pressure, so 

Pipe fitting mould that the flow rate of the plastic melt through the slit increases abruptly, increasing the speed of the plastic melt and lowering the solution. The viscosity changes the flow state and the plastic can quickly and evenly fill the cavity. For multi-cavity molds, adjusting the size of the gate also allows the cavity to be fed simultaneously.

The gate also acts to prevent earlier solidification and backflow of the melt in the cavity. The gate is usually formed into the smallest cross section in the casting, which facilitates the separation of the plastic part from the gate after the plastic part is injection molded. The gate allows the molten plastic to enter the filled cavity at the fastest rate. The cross section of the gate must be small, and the length should be short to meet the flow speed. The division is cooled and closed to facilitate the separation of the plastic parts and to ensure the minimum residue of the gate. The gate plays an important role in the whole mold. It is the mouth of all the molds. His good or bad directly affects the success or failure of the whole mold. You can't despise him.
