20140103578 | VALVE PIN BUSHING FOR THE HOT RUNNER OF AN INJECTION MOLD - To improve the flow symmetry and the molding quality, it is presented a valve pin bushing for the hot runner of an injection mold, including two input channels, each having a geometric axis and through which the material to be injected can enter through an outlet into, and an output channel, which extends along a longitudinal axis up to an output from which the material can exit the valve pin bushing. The portions of the geometric axes, which extend at the outlet are arranged so that on any imaginary plane passing through the longitudinal axis there lies at most one portion. | 04-17-2014 |
20100038819 | PROCESS FOR THE PRODUCTION OF PLATES MADE OF TRANSPARENT PLASTIC MATERIAL WITH NON-TRANSPARENT OVERINJECTED PARTS - Described herein is a process for the production of plates made of transparent plastic material with non-transparent overmoulded parts by means of a first direct injection and subsequent compression for the formation of the transparent plate, and a second injection for overmoulding said parts on the transparent plate, covering the indicators or witness marks of the first injection. Each injection can be in spots controlled in sequence, and the second injection can be followed by a respective step of post-compression. | 02-18-2010 |
20090321994 | INJECTOR FOR INJECTION MOULDING OF PLASTIC MATERIALS - An injector for injection moulding of plastic materials incorporates a vacuum device for creating a suction pressure within the mould in an area corresponding to the injection point, prior to the injection of the plastic material. | 12-31-2009 |
20090117220 | Auxiliary supporting structure for presses, and plastics molding press equipped with such a structure - An auxiliary supporting structure for presses, having an auxiliary mold platen having a front surface designed to firmly, but removably, support a half-mold; a number of hydraulic supporting cylinders, which project from the rear of the auxiliary mold platen, in a direction parallel to a reference axis perpendicular to the plane of the auxiliary mold platen; mounting means for firmly, but removably, fixing the hydraulic cylinders to the front surface of a movable mold platen of the press; a hydraulic distributor for regulating pressurized-oil flow to and from each hydraulic cylinder independently of the others; and an electronic central control unit for controlling the hydraulic distributor as a function of signals from a number of external sensors, to enable the hydraulic cylinders to instantaneously compensate any asymmetric distribution of the mechanical forces exerted on the half-mold as the plastic material is injected. | 05-07-2009 |
20090022842 | INJECTOR FOR INJECTION-MOULDING OF PLASTIC MATERIALS - An injector for injection-moulding of plastic materials including a generally cylindrical body, wound on the outside of which are at least two pairs of mutually independent electrical heating resistors and associated to which are respective control thermocouples. | 01-22-2009 |
20080299248 | Plastics injection molding machine - A plastics injection molding machine having a mold comprising at least two metal shells which are brought into contact with each other and are designed to form a closed cavity negatively reproducing the shape of the plastic part for molding, and a plastic material feed line which is supplied with and liquefies a stream of granular plastic material, and which feeds the liquid plastic material in controlled manner to the cavity formed when the two metal shells are mated; the machine also having a detergent mixture feed circuit which, on command, feeds a given quantity of a detergent mixture into the plastic material feed line, and an electronic central control unit for controlling the detergent mixture feed circuit. | 12-04-2008 |
