Why Choosing Enqi molding For Plastic Injection Molding?
Injection molding process boasts a diversity of advantages, among which the most significant ones are shown below:

The process is able to be fully automated to realize high production efficiency (injection molding can be used to mass-produce parts in a very effective way).

The process makes it possible to produce the immensely detailed or complicatedly designed parts. What you need is an engineering design company or an internal design department to develop great designs. Yet, the moment apart is the manufacturing process, there would be little finishing work needing to be done because the produced parts look extremely finished.

To gain the desired material properties in your final products, you are allowed to select a wide range of materials in the process or mix different materials for a combined outcome. The combined use of more than 1 material (usually 2 different materials) is referred to as co-injection molding. Generally speaking, very little waste will be produced in the injection molding process, because excessive materials are able to be easily recycled.

Mold inserts can be used to produce a new part (through this process, you can change the internal cavity without complete redesigning or re-machining of the steel or aluminum tools by CNC). Apparently, the life cycle of the tooling will be dependent on the injection molding materials, and particularly on the geometry of the part and the barrel temperature of the materials. To be specific, high temperatures and delicate (thin) geometric shapes will shorten the service life of the tooling.

However, the injection molding process also has some distinct disadvantages. For example, the tooling costs are too high that it is not easy for average independent designers to reach them. Keep this in mind, you will know how to choose the alternatives.

The Detail of The Process
During the molding process, the plastic pellets will be first delivered into the high-temperature injection barrel through the hopper, where they are heated, melted and plasticized into a sticky molten flow, which will then be injected into a lower temperature closed mold through the injection nozzle at a high speed under the great pushing pressure exerted by the plunger or the screw.

Under the great pressure, the molten plastic will fill the entire cavity and will also be compacted. After that, the plunger or the screw will return after a period of pressure holding. At this point, it is possible to flow back from the cavity into the sprue and runner system.

When the mold opens after cooling and forming, the product will be released from the mold cavity.
