Understanding molds and tools in injection molding manufacturing

Understanding molds and tools in injection molding manufacturing
Apr 30 , 2021

When molds and tooling are mentioned, what comes to mind are the parts that are produced through the use of processes like blow molding or injection molding.

These parts can be used for many different purposes in different fields and industries, and for the success of any process in which they will be used, getting them used correctly for the first time is critical.


Mould
The mold is a hollow block used to set the shape of the product to be manufactured. It can be made of different materials, the most common of which are aluminum, steel, alloys, and copper. It also has different components.
These components include pins, bases, risers, ejectors, guides, bushings, and alignment equipment.
Because the mold is the shape of the final product, the correct mold must always be used. The manufacturer should have a thorough understanding of the final product to be made. Otherwise, the entire chain will be sacrificed-from the smallest part to the role played.

Injection Molding
Now that you have a better understanding of the role of molds in the production process, you can better understand what injection molding is.
As the name suggests, injection molding involves injecting any type of material into a mold. From metal to polymer, from glass to elastomer, different materials can be used in the process.
Basically, the material is fed into a heated barrel, where it is mixed and pressed into the middle of the mold. From here, the material hardens as it cools, forming the final product.

Blow molding
Blow molding is used to produce hollow plastic parts. It can be done in 3 different ways: injection blow molding, injection stretch blow molding and extrusion blow molding.
Basically, this process requires air to blow the plastic material into the mold. From here, the plastic cools down to form the final product.


Tooling
Tools involve finding and obtaining information about the different components and machines needed to produce something. It covers many categories,  fixtures, gauges, molds, dies, cutting patterns, and equipment.
The tool process is more than just choosing based on existing or other tools used.

Remember that the results of the processing process directly affect the quality of the final product and the cost of the entire process. Therefore, if you are responsible for this process, you need to be extra careful.
