Plastic Injection

We offer a wide range of plastic finished and semi-finished products.

By using state-of-the-art injection molding techniques and technologies, our processes are easily controlled and repeated.

Plastic Injection

Plastic injection molding is a process of molding plastic materials using machines called injection molders. The process of injection molding plastic materials allows mass production as the granulated plastic mass is melted and poured into the mold, allowed to cool down and harden and when it is completely cold, it is opened and new mass is poured in, thus producing exactly the same plastic products.

How the plastic injection molding process works

First, the granulated plastic mass is melted, then heated and pressurized, and finally injected into the mold, which allows the injected mass to retain the shape. The plastic injection molding begins by putting the plastic into the machine through the hopper, from which it slides into the injection mold cylinder with external heaters and a reciprocating screw. When entering the cylinder, it reaches the required melting temperature and there is usually enough mass for several injections. The injection molder plates (one flexible and one fixed) use locking force to push the tool together.

The reciprocating screw rotates and moves the molten plastic down the cylinder, while the screw is moving back. In this way, it stops moving and starts acting as a piston and injects the plastic into the spray tool under pressure. This phase is called the inkjet phase. However, the injection molding of the plastic is not yet complete, as in the next phase, the mass is cooled down and hardened. When the product is sufficiently cooled, the flexible plate moves away from the fixed plate of the molder, opening the inkjet tool. The product is removed from the tool using an air jet or ejector.

Finished and semi-finished products

The industrial injection molding technique enables the production of a wide range of plastic finished and semi-finished products. Today, plastic products are used in all areas, which is why plastic injection molding is becoming a widely used technology that can meet the needs of mass production.

Injection molding is used in the food industry to produce everything from plastic food packaging to plastic bottle stoppers. It is also used to produce promotional and table stands as well as different types of containers, storage boxes, cases, various trays, sprinklers, table tops, dye containers, etc. In short, these products are used in all areas of life, so plastic injection molding is a necessary process that provides fast and quality solutions. The automotive industry and the electric industry also rely heavily on the use of plastic finished and semi-finished products for further production and use.

The advantages of injection molding

The process certainly has many advantages, mainly in the fact that the process can be controlled and is easily repeated, but also in the fact that it can be used for the production of a wide range of materials and it saves a great deal of time after injection, since the products are finished immediately after the process is completed. One of the great advantages is also the minimal amount of waste produced, high level of automation, high production capacity and high product tolerance even in very large batches.

This technologically advanced and simple provides excellent products both for everyday as well as industrial use in different areas, which is a necessity in this day and age. Plastic injection molding saves time, costs and, most importantly, easily meets the market needs for finished and semi-finished plastic products. Considering the minimal amount of waste, it is also beneficial to the envrionment.
