ENGEL couples innovative injection molding technology with peak efficiency and cost effectiveness. The injection molding machine manufacturer and automation expert has demonstrated its high level of system solutions competence at Plastpol held recently in Kielce/Poland.
At Plastpol 2011, International Fair for Plastics and Rubber Processing (as the fair is to be called in future) ENGEL had presented processing of cross-linking and thermoplastic elastomers. For this purpose it will be using a vertical ENGEL elast 750/250 V type machine and a 4+4 cavity mould from ORP Stampi in which two pen casings and caps are produced in one cycle each. They will be moulded from type HTV-80ShA hard silicone from PMG.
ENGEL duo 3550/500 pico consumes significantly less energy for the production of crates made of polypropylene than conventional hydraulic injection molding machines. The economical working method of the 500-tonne machine, operating at the trade fair with a Haidlmair mould, is attributable to the servohydraulic ENGEL ecodrive, which can be supplied as an option for all hydraulic machines from the ENGEL product programme.
Saving energy and cooling water
ENGEL ecodrive consists of a servomotor with fixed displacement, or variable capacity pump, instead of a permanently running asynchronous motor, so that the speed of the machine is directly related to the rpm. During standstill times, cooling phases for example, the machine does not consume any power at all. This enables the ENGEL hydraulic machines to achieve energy consumption figures that can match up against those of all-electric machines. Energy consumption is reduced depending on the application and machine type by up to 70%.
At the same time cooling water consumption on the oil cooler is reduced to a minimum, in many cases to zero. In conventional hydraulic drive concepts the portion of electrical energy that is not used for movement is converted to heat and fed, for the most part, to the hydraulic oil. ENGEL ecodrive reduces energy losses to such a high extent that with the exception of high performance applications only minimal heating of the hydraulic oil occurs. The oil temperature thus becomes an indicator of the energy efficiency of the machine.
Hybrid machine for top efficiency
ENGEL e-victory 310/90 which is utilized to manufacture ice scrapers made of polypropylene at the stand, likewise achieves maximum efficiency. The standard ENGEL e-victory hybrid machine is fitted with an ecodrive, making it ideal for applications with hydraulic components, e.g. core pulls, since despite the electrical injection unit the hydraulics stay on board.
As one of the world market leaders, they offer integrated system solutions. This means: injection molding technology from a single source. Machine, mould project engineering, automation, process, training and service are all perfectly integrated with ENGEL.
