Manufacturing of the plastic injection mold

Injection molds are an essential tool when it comes to precision manufacturing of plastic parts. They result in parts with perfect design and long life, making them a very practical tool in manufacturing.

What is the objective of plastic injection molding?

The final objective is to obtain the desired part, using polymers in a liquid state. This is possible thanks to injection molds, as they are responsible for distributing the molten plastic at high temperature along the mold and thus obtaining the desired shape when it solidifies.

Phases of injection molding

Design of the part

In this phase, we decide what shape our part will take and what dimensions it should have.

Manufacture of the plastic injection mold

This is one of the fundamental parts of the manufacturing process, as the finish and resistance of the mold must be in accordance with the material that will be used to manufacture the desired part.

Injection moulding can assist you in bringing your product to life, regardless of whether you are trying to make a small batch or a large amount. Finding the ideal plastic injection mould design business to collaborate with on this project is crucial.

Extraction of the part

In this phase we work with the material in a liquid state, so we must control the contraction and expansion of the material, this is done with a rigorous control of the temperature at which our material becomes liquid, to be able to expand it and make it acquire the appropriate shape.

Cleaning and polishing

Once the desired shape is obtained, it is necessary to give the piece some finishing touches, that is, to treat the surface of the plastic piece.

Main advantages of using plastic injection molding to manufacture parts

Plastic injection molding is an extremely versatile method of producing parts and products. It is one of the most popular methods of manufacturing parts because it has multiple advantages over other plastic molding methods. Plastic injection molding is not only easier and more reliable, but it is also extremely efficient. You should not hesitate to use this method to manufacture parts.

These are the main advantages of using injection molding to manufacture plastic parts and components.

Detailed features and complex geometry

Injection molds are subjected to extremely high pressure. As a result, the plastic inside the molds is pressed more strongly against the mold than in any other molding process. Because of this excessively high pressure, it is possible to add a great deal of detail to the part design.

In addition, because of the high pressure exerted during the molding process, complex and intricate shapes that would otherwise be too complicated and expensive to manufacture can be designed and manufactured with ease.

High efficiency

Once the injection molds have been designed to the customer's specifications and the presses have been pre-programmed, the actual molding process is very fast compared to other molding methods. The plastic injection molding process takes very little time, allowing more parts to be made from a single mold. The high production rate makes plastic injection molding more cost effective and efficient. In general, hot runner ejection molding systems produce more consistent quality parts with faster cycle times, but it is not as easy to change colors and hot runners do not support some heat-sensitive polymers.

The most important point is...

The use of injection molding also ensures that manufactured parts require virtually no work after production. In fact, the parts have a more or less finished appearance after being ejected from the injection molds.

Today, plastic injection molding is an environmentally friendly process.
