Description

SPG Machinery (Shandong) is the new dimension on the extrusion scene, founded on the basis of reliable and newly organized specialists in extrusion. The state-of-the-art extrusion product line ECO CONCEPT meets all possible requirements of modern extrusion. The new EC extrusion lines convince with the highest functionality, perfect technology, ergonomic handling and design. Developed on the basis of customer process  analysis and state-of-the-art extrusion and energy technology, the extrusion product line ECO CONCEPT convinces through it revolutionary concept of energy saving profile extrusion. 
ECO Plus Concept is the new dimension on the extrusion scene, to offer an optimal solution for energy and environment in the extrusion. ECO Plus Concept is a patented technology for energy saving system, which was developed by our headquarter in Austria on the basis of reliable know-how and experiences in the extrusion business since many years. There’re two alternative for ECO Plus Concept: Central Vacuum Energy Saving System, Control Vac System.
The feature of ECO Plus
→Saving Energy.
→Reducting noice.

→Ergonomic design & control system
ECO Tech 
Energy saving systems
All of SPG’s energy-saving systems are a part of SPG’s extrusion systems. The biggest energy saving is achieved in the extruder drive and the vacuum pumps in the calibration table. The fully automated energy systems control and optimize the consumption of energy in the dry calibrators, water vacuum tank and water/air separation. By using the energy system, it is possible under optimum conditions to save up to *5% of the line’s entire consumption in the area of the calibration table.
