Development of a new ultra compact all-electric type molding machine as augmentation of ultra compact molding machines for micromolding use.
Nissei Plastic Industrial Co., Ltd. has developed and started overseas sales of an ultra compact all-electric type injection molding machine with a mold clamping force of 5 tons (49 kN), as the enrichment of the machines for micromolding use (minute and microscopic molding use), the "ELJECT EP5 Real Mini." Recently, micromolding has attracted considerable attention as minute, microscopic and small-volume molding. This molding meets the requirements for miniaturization, weight reduction and making thin-wall of products. It also aims at improving productivity and reducing initial costs. It has various advantages such as easiness and streamlining of production number control, making high quality products and simplification of inspection processes by means of single-cavity molding of precision parts, resin consumption saving, reduction in mold costs, and dealing with production of small quantity lots of various kinds. In order to operate this micromolding, it is important to adopt a molding machine with the most suitable mold clamping force for weight and measurements of molded products. Our company already has put electric machines of 3 tons (AU3E) and 7 tons (HM7 DENKEY) to practical use, being ahead of other companies. We have abundant business performance in domestic and foreign markets which is being appreciated. The ultra compact electric molding machine, "ELJECT EP5 Real Mini," is an all-electric type machine developed by the company for molding of products with one shot weight of about 0.5 gram to 5 grams. The characteristics of the molding machine are as follows: In regard to the injection mechanism; In regard to the injection mechanism;
In regard to the mold clamping mechanism;
This machine is mounted with a controller, the "NC9300T," with a 10.4 inch TFT color liquid crystal screen of a thin type broad visual field. Furthermore, an "infrared ray" mold monitor can be mounted as an option for the first time in the industry. Unlike existing types, as the feature of this equipment, high precision monitoring can be conducted without being affected by extraneous disturbance light. Also it makes possible to detect faults of products including black-colored ones, being not influenced by color. This "ELJECT EP5 Real Mini" and the "NP7 Real Mini" (a hydraulic type) which has been put on the market earlier, are both molding machines intended for the extremely tiny precision product industry. The machines demonstrate respective advantages of an electric type and hydraulic type. Main specifications of the machine
