Plastic Injection Molding


Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. Plastic Injection Molding is one of the most frequently used manufacturing processes for creating plastic parts. Thanks to its high-precision, repeatability, and cost efficiency at scale, plastic injection molding is used for a variety of products and parts from the smallest insert up to large automotive & aerospace parts.


The plastic injection molding process requires an injection molding machine, raw plastic material, and a machined mold. The raw plastic material is first melted in the injection unit and is then injected into the mold, where it cools and solidifies into the final plastic part.

The key steps in the injection molding process include:


The two sides of the mold are closed and clamped shut.


The material is fed into the machine and pushed towards the mold. While this is happening, the material is melted by heat and pressure. The plastic is then injected into the mold, this process is called “Shot”.


The plastic in the mold cools and solidifies into the shape of the part.


After the part cools, it is ejected from the mold.

Auwell offers 2 business models to meet the needs of the client for plastic injection molding projects. Namely supply tooling only models or, final products models.

-Tooling Only Models

For this business model, Auwell offers the tooling design based on the product design and machine data for client confirmation, the details include tooling structure, lifetime, tooling material, hardness, etc. Clients may provide completed tooling designs for production. For this tooling only option, for standard parts, we will use the most common with globally recognized one for easy maintenance. In general, this option is preferred for large size and high-volume products, Plastic Injection Tooling Automotive is a typical catalogue for this business model.

-Final Products Models

For this business model, Auwell is responsible for the plastic injection molding parts, and to meet the client’s specifications. The type of injection machine and tooling structure/design used is decided by our team. For this business model, once the client pays the tooling cost, Auwell will be responsible for tooling maintenance and replacement for the entire product lifetime. This model is preferred for small sizes and precise plastic injection molding parts. Please refer to “Plastic Injection Parts” section for more details.

Another key difference of the two-business model is, for “Tooling Only Model”, the mold cost is considerable higher than “Final Products Model” as for “Final Products Model”, Auwell does not make any margin from the tooling development. For “Final Products Model”, if the clients want to take the mold or, shift to another supplier, it is not guaranteed that the mold works properly at another machine at another manufacture, and, a certain proportion of mold development cost will be charged before mold transferring.

Apart from plastic injection molding, we also provide the following services:

-Rapid 3D printed prototypes


-Insert molding


-Rubber & Silicone Molding
