Molding (or moulding) is an efficient way for manufacturers to shape materials the way they want without much difficulty. The molding process is used to make everyday objects such as Tupperware, bottles in different forms, or even certain products made of wood.
The most popular type of molding is of course plastic molding, as it is used for a variety of uses as already stated above. In order to manufacture and produce successful molds it is of the highest importance that one uses the best quality tools, equipment, and trusted processes. Rather invest in something you know is going to produce you more money that you spent making it.
How many different molding processes are there?
There are two different types of plastic molding, namely thermosets and thermoplastics. The only thing that creates the difference between these two is temperature during which the process takes place. Because there are so many different molding processes the equipment used will differ with every process that is implemented. This article will concentrate on the extrusion, injection, and blow molding, which is a combination of the two processes.
How do these molding processes work?
Just as the equipment will differ, so will the process of molding differ with each of the abovementioned types of molding.
Extrusion molding: during this process the raw plastic is fed into a gyrating chamber. This chamber will spin with the help of an extruder, which will melt the plastic and in its turn shape the plastic the way you want. The end product is then dropped onto a conveyor belt where it is cooled with water. Thereafter the product is cut and given the final adjustments.
Injection molding: this process is similar to extrusion molding, but during this process the hopper is introduced. When the raw plastic is fed to the gyrating chamber, it is done with a hopper. Once it is in the gyrating chamber, the plastic is put into a cold mold with high pressure. The reason for this is that through the cooling process, the end product will be more refined and clean.
Blow molding: this process is a combination of blow molding and extrusion molding. After the injection molding has been done, the plastic will be used with a die that will create a heated plastic tube with a cold mold around it. During the extrusion blowing however, the compressed air will be wafted by such a tube so that it creates a hollow shape inside the plastic. Blow molding ensures that the final product is perfectly sculpted the way it should be.
What materials can be used or produced by these processes?
During injection molding it is usually raw plastic like powder, pellets, or beads that is used. The end products are usually plastic films, sheets, and pipes. With extrusion molding one can use the same raw plastic substances, but it will produce final products such as bottle caps, toys, furniture, or containers. Blow molding will of course be able to produce both the final products of these two processes.
