Peripherals that save energy

The young company, created in 2003, exports 85 percent of its production in Europe, and in Spain is represented by the firm Guzman polymers that exclusively sells its product range and gives technical service teams.
Not missed what's new in the last trade show K 2007, where Main Tech presented a new series of dehumidifiers tires and a volumetric dispenser for powder, aimed at the sector of the molding by injection and extrusion.
The exhibition programme of the Italian firm provides for their participation in Fakuma (Friedrichshafen, Germany), Equiplast (Barcelona), Europlast (Paris).

In the field of centralized facilities, Main Tech has been launched for the extrusion sector facilities specialized in transport and dosing of materials in dust, and large transport facilities and dosing of materials in pelletsespecially for lightweight materials which may have transport problems.

An example of installation, the main demand of the client was the used minimum of crushed material, for that reason developed a few silos with reduced system, pneumatic transport with density controlled in the vacuum control system and automatic regulation of the capacity of air, silos of small dimensions for light granulates, loading system of thermoforming with mechanical extraction and dispensers placed on the extruder to maintain desired productivity.

Applications of this kind have been implemented in other industrial contexts. The latest innovations have been developed in the installation that uses an extruder of 3 thousand kilograms time for the production of PS plate.

Main Tech provides to transformers in all technology segments: injection molding, blowing, extrusion and recycling. Teams of course change depending on the application, especially when it's crushed materials. Different transport systems with respect to those used for the movement of the pellets (solutions for the generation of vacuum with high prevalence and capacity of air) are required for these and even if conduits have different diameters it is possible that the crushed tend to ' plug '. In addition, the container that receives and loads the processing machine must be completely redesigned, and storage silos must be cylindrical with flat bottom and mechanical extractor. The density of transport must be constant and the pressure must therefore be monitored.

For materials in powder speech changes completely, may be necessary to pay attention to the filters. Also in this case the container vacuum with a specific design may be help changing the filter depending on the type of material used. The storage system is completely different from the of the granules: the Fund should be vibration and must be controlled the speed of transport. Finally, the dosage of the dust requires higher precision than the granules.

For energy saving, centralized facilities of Main Tech equipped with constant monitoring of the management of the motor inverter. The application of the speed of the transport control is an optional that can be installed on any system of transport. The reduction of energy consumption is achieved by controlling the rotation of the generator in operation of vacuum pressure to maintain. Using a vacuum pump controlled by the Main Tech control system, you can get significant savings: according to calculations made by the technicians, the cost of the vacuum generator had in less than a year.

Energy saving is vital to Main Tech. The company has in its catalog with a wide range of dehumidifiers of low energy consumption, in particular emphasizes small dehumidifier DR202 of 40 m³/h of capacity of air to dehumidify 25 kilograms of nylon only consumes about 0.01 kWh of electrical energy. The range has the energy recovery system with the ability to control the flow of air from the dehumidifier.

Some of the projects Main Tech is carrying out, in collaboration with end producers, are related to the study of new processes for the use of nano powder material such as additives for the production of technical polymers.

The contribution of Main Tech provides for the storage, treatment, extraction of the finished product and packaging phase, either for components in granule or powder with the development of specific dehumidifiers.
