3 Basic Steps of the Injection Molding Process

Injection molding is one popular manufacturing process, and there are several reasons behind it. For those who don’t know, this process is used for the production of consumer goods, especially those that have to be produced in masses. The injection molding method is famous, especially for making plastic products in a huge quantity.

Injection Moulding: The Process Step By Step

Injection Molding Process

If you want to get your products manufactured and if you know that you need to get a huge quantity of them produced, then we’d suggest you to try qmolding. Qmolding is one of the most famous companies for injection molding. Especially if you want to produce plastic items, then this is the place you should refer to.

Now comes the actual part of what we are here today. Today we will be telling you about 3 of the most important and basic steps around which the whole molding process revolves.

Step1: Product Design

In the production process, designing is the most important and crucial stage. It’s the earliest stage where you have to be very careful in order to reduce any extra costly mistakes. In the designing process, you have to consider several different things like the aesthetics, the pattern, the functions, and the target designs, etc.

In short, it’s a whole complex process that requires some serious investment of time and energy because if it goes right, the next two steps will be easier for you, and it will all be done in a short while.

The design of the product is completed with the help of Computer-Aided Design (CAD) software like SolidWorks etc. This is the reason why you should always hire the right design engineer here so that you get your desired results.

Step2: The Design Of The Mold During Injection Molding

Once you know that the design is ready, it’s finalized and that it’s going to enter the next stage of production, this is when you have to work on the mold design. Here are the types of molds that you’ll get with these types of metals, From hardened steel, the mold will be the best in quality, but it’s not the right choice for you if you are short on money.

The hardened steel mold will be expensive. The next type is that of pre-hardened steel. Just as the name tells, this metal isn’t as hard as the hardened steel, but you still can get your desired results with it.

Last but not least, there’s Aluminum, which is known as one of the most common materials used as a prototype tool. It’s cheaper in price, so people usually opt for it when they have to design their mold.

Step3: The Injection Molding Production Stage

When the product is designed properly when it’s molded, that’s when the real stage of production begins. The thermoplastic material enters the Fed into the heating barrel, and that’s when those thermoplastic granules melt. A large screw is used to heat the plastic through the door and the mold.

Once the mold is in place, the screws are placed in it right where they are supposed to be so that it can cool down. Then a certain amount of pressure is applied where the exit of the screw, and the mold opens up, and then it expels.


These are the three main steps involved in the injection molding process. It’s an easy process with no complications and hassles that you can’t understand. Now that you know what it is start looking for a service provider like qmolding and get your plastic items produced.
