In the world of injection molding, innovation and precision are key components. Today at aXpel injection we would like to highlight a particular aspect of this technology, often overlooked but nonetheless essential: the three-zone screw.
The three-zone screw is the heart of every injection molding machine and plays a crucial role in the processing of plastic materials. It consists of three main areas: the feed zone, the compression zone and the dosing zone. But what exactly happens in these three zones?
1. Infeed zone: This is where the plastic granules are fed into the screw. The deep and wide flights of the auger ensure that the material is picked up evenly.
2. Compression Zone: The material is heated and compressed, going from a solid to a liquid state. This transition is critical to ensure the material is malleable under high pressure and temperature.
3. Dosing zone: The now liquid plastic is made available for the injection molding process. The flat and narrow flights ensure that the material is dosed evenly and then injected into the mould.
The design of the three-zone screw ensures optimal plastic processing, which ensures the quality and consistency of the plastic parts produced. It plays a crucial role in controlling melt flow, temperature and pressure in the process, and can have a significant impact on productivity, energy efficiency and product quality.
In aXpel injection, we attach great importance to the quality of our injection molds, and the three-zone screw is an important part of it. By constantly developing and optimizing our tools and processes, we strive to offer our customers the highest quality and efficiency.
The three-zone screw may seem inconspicuous, but it is an example of how every detail counts in injection molding technology.
