Plastic Injection Process of Molding Company

It is no exaggeration to say that plastic is the cornerstone of our society. It is hard to imagine what our life will be like without the invention of plastic. Because many of our daily products are made of plastic, it is easy to understand why plastic injection molding is a huge industry.
plastic injection process
The first step in the injection molding process is the clamping of the mold. This clamping device is a standard part of an injection machine. Mold, clamping device and injection device. The clip is a mold that melts the plastic injection, the injection mold is held under pressure, and the plastic is cooled.


Prepare the mold

 
Polymer resin (pill) to drill (screw) is a large single-bottomed container. An electric or hydraulic motor is responsible for passing spiral pills inside the heated barrel through the spiral groove. The mold cavity before the door limits the flow into the mold and limits backflow. The pressure exerted to push through the groove to the doorway also generates heat inside the cylinder, helping to melt the polymer and prepare to inject the mold.
 
Injection of polymer melt into the mold

As the drill is injected at high pressure into the polymer melt in the mold (usually 10,000 - 30,000 psi), it is possessed, and more melt is added to ensure that the cooling and solidifying shrinkage does not leave the notched final product. The final door solidifies and isolates the mold injection cylinder.
 
Cooling mold

The mold is usually air or water cooling. Sometimes the hole is boring to the mold so that the coolant (such as water) spreads. Injection mold cooling consumes about 85% of the entire process cycle time.
 
Unloading and stripping

After solidification, the clamped halves of the mold are closed together with the open allowable portion removed. The injection molding process can be repeated.
 
About 30% of plastic products use an injection molding process. A large number of these products are made using custom injection molding techniques. Six steps involved in the injection molding process, the prototype had been and after the approval.
 
The first step in the injection molding process is the clamping of the mold. This clamping device is a standard part of an injection machine. Mold, clamping device and injection device. The clamp is a mold that holds the melt while the plastic is injected, the injection mold is held under pressure, and the plastic is cooled.
 
Next is the injection of the actual molten plastic. Plastics usually start the process for granules, which are put into a large funnel. The ball is then fed by a cylinder; they are heated here until they become molten plastic easily forced to die. Plastic in the mold, it is clamped under pressure until it cools.
 
The next few steps include the residential phase, which is to ensure that all mold cavities are filled with molten plastic. After the residential phase, the cooling process begins and continues until the plastic becomes a solid internal form. Finally, the mold is opened and the newly formed plastic part is ejected from its mold. Any extra plastic mold outside the section.
 
As with any process, there are advantages and disadvantages associated with plastic injection molding. The advantages of most companies outweigh the disadvantages, including the ability to maintain high levels of production, to be able to duplicate products that produce a high latitude and to do most of the work of lower labor costs by machines. Plastic injection molding also has the benefit of reduced waste costs because the mold is so accurate.
