Tool coatings are often made from a variety of materials.

Plastic Mold Making

great choice

The process is a great choice for large-scale production of identical objects. Its benefits include repeatability, high tolerances, and a wide variety of materials. This process is typically automated, which reduces manufacturing costs significantly. However, this process requires that the parts be designed so that they can be molded easily.

injection molding

After the injection molding cycle, post-processing is required. This post-processing removes excess material from the part. Plastic grinders, also known as granulators, are used to grind the trimmings into pellets. This regrind material is then mixed with the raw material in the correct proportion. The mold used in plastic mold making can be cast or welded. It is important to select a quality mold. Plastic molds are made from various types of plastic. Some are thin-gauge, and can be used to make disposable cups, lids, and trays. Others require a thicker gauge.

Various materials can be used, including steel, aluminum, and beryllium-copper alloy. CAD or 3D printing technology is also available for creating molds. After the molding process, the mold is cooled down. This process is often used to produce large hollow objects. Learn more about formstøping av plast plaststøping

Injection molding is the most popular way to produce plastic parts. This process uses high temperatures and rotational movement to coat the inside of the mold with plastic. The process also doesn’t require high pressure, lowering material costs. It allows manufacturers to produce prototypes quickly.

This process is highly precise. The raw material is injected under high pressure into a mould, which then shapes the polymer into the desired shape. Its quality directly affects the quality of the finished product. Rotational movement helps the plastic material to coat the mold inside evenly.

Tool steel moulds are usually used, although aluminum and stainless steel moulds are sometimes used for specific applications. In addition to minimizing waste, rotational molding allows engineers and designers to choose the most appropriate materials for their application. 

Injection molding can be performed on a wide range of materials, and is a fast, efficient way to create plastic parts for all sorts of applications. Rotational molding is environmentally friendly and economical. They can also add small details, such as threads, inserts, and minor cuts. 

The most common plastics used for injection molding are thermoplastics and thermosets. The latter are used extensively in manufacturing, and are highly reusable. Thick-gauge thermoforming is used to make utility vehicle beds, refrigerator liners, and appliance trays.

multiple cavities

The mould can contain one or multiple cavities and can produce identical or varying geometries. For plastic injection molding to be successful, the process should be carried out under the guidance of an expert. Companies that have been producing metal parts for many years may need to modify their processes for plastic parts. For instance, the design and engineering teams of the company should consult on which plastic would be best for the product. Some plastics, like polycarbonate, are more durable than others and will offer better performance over a longer period of time. Others, such as polypropylene, offer a higher tensile strength.

While some people have a reluctance to invest in this technology, the advantages of this process far outweigh the drawbacks. This uniformly coats the inside of the mold's surfaces.

Complex and Expensive

The process is complex and expensive, but it is a great choice for the right projects. The upfront costs are due to the design, testing, and tooling needed for this process.


Plastic mold making involves a process called rotomolding in which a hollow mold is filled with thermoplastic powder. A heated mold is rotated around two perpendicular axes, causing the plastic powder to melt.
