Within the packaging industry, a plastic injection machine is widely used to manufacture a large number of containers or plastic products such as cups, jars, and buckets. Different types of plastics that exist are essential materials for modern life, their versatility allows them to take almost any shape. Depending on the technique used, these can change their hardness.

The most used technique for the production of plastic products is injection molding, by means of a plastic injector. The reason is that it is possible to shape complex pieces and these usually do not require specific finishes.

It is a basic process, the plastic resin pellets (PET, HDPE, PP, etc.) are small pieces that have not yet taken any form, these are introduced into a part of the plastic injection machine melts it, later they are pushed, and injected into the mold, once they have cooled until they take the shape they are released.

What is a plastic injector and what are its functions?

The one responsible for shaping these is a plastic injector, it is made up of a motor responsible for providing energy to each part, a hydraulic pump that drives the oil, and pistons that move to perform the different functions of the machine. 

In the first place, the plastic resin pellets are deposited in the hopper according to the product to be manufactured, this ends in the barrel where, thanks to some resistances with which it is surrounded, the material melts until it becomes a viscous liquid, another piston pushes the melted material through the barrel to the platen, where the mold in the shape of the product is located. There is also a control console from where the heat and speed with which each batch of products will be manufactured are controlled. 

Which of our products are manufactured with a plastic injection machine?

At Maxipet we use the injection molding technique to originate our HDPE products, that is, our jerrycans are manufactured using an injection machine. We supervise every moment of the process to guarantee that you will have high quality in each of our containers.
