Assisted injection of plastics (English: AIM = Assisted Injection moulding is a type of plastic processing that improves the quality of products and significantly saves production costs. This technology involves injection of gas or water under high pressure into plastic contained in an injection mould.
Assisted injection of plastics (English: AIM = Assisted Injection moulding) is part of the processing of plastics that improves the quality of products and significantly saves production costs.
This technology involves injection of gas or water under high pressure into plastic contained in an injection mould. This way, the component is perforated with cavities to reduce its weight. The compression pressure can be better distributed and pitting prevented. The distribution of gas pressure over the component´s surface is equalized, which also helps eliminate pitting and reduces the closing force, thus often reducing its weight and cycle time.
Other methods make it possible to produce foam from plastic resins to reduce the density of the material or to change the temperature of the injection mould to prevent the formation of cold joints. Depending on the specific application, various technologies can be combined, which brings further benefits.
Our team of over 50 professionals operating in 20 branches located around the world has the technical facilities and the relevant engineering expertise necessary to be able to provide technical support throughout the whole production process from commissioning and operator training to maintenance tasks.
Moreover, for your equipment for assisted injection of plastics, we continuously ensure the supply of original spare parts.
We emphasize transparency and therefore we provide you with brief information on the product and the principle of functionality of individual technologies, so that you can achieve time and cost savings from the start.
Safe and competent handling of the product during its operation and maintenance can extend the service life of all the components and eliminate unnecessary operational downtime – your investment is thus ensured in the long term. Maximator service and maintenance contracts guarantee the execution of regular preventive servicing and upkeep of your equipment.
We will facilitate your daily work by organizing your service and maintenance schedule. We will plan and carry out ongoing maintenance to ensure that your machine maintains its maximum performance.

In order to use the technology of assisted injection of plastics with gas and water support, it is necessary to implement basically two additional functions: pressurization and pressure regulation.
There are two types of gas compression used in assisted injection of plastics with gas support. On the one hand, it is intermittent gas compressing that is used mainly in the GIT process of individual machines, and on the other hand, continuous compressed gas generating that uses central supply of compressed gas to several injection presses. Gas pressure regulation is ensured by individual pressure regulating modules for each injection press. The pressure regulating module reduces the pressure that the system generates to the required gas pressure. Communication with the injection press is handled by an electrical control system. Maximator offers compressor station, regulation modules, as well as combined compressor-regulation modules, both for intermittent and continuous gas compression.
In the field of assisted injection of plastics with water support, the WID MAXIMATOR device has the capacity both for pressure generating and pressure regulating (in one combined device). The following diagrams show the general structure of the technologies used.
