| 20110305789 | SYSTEM FOR POST-TREATING AND TRANSFERRING PREFORMS - A system for the post-treatment of preforms ( | 12-15-2011 |
| 20110293774 | GATE ADAPTER AND GATE SYSTEM FOR A GATE ADAPTER - A gate adapter for receiving a molten molding material and for the discharge thereof to a gate distributor block ( | 12-01-2011 |
| 20110042855 | Receiving System - A system and method for post-treatment of a hollow body molding produced in an injection molding mold. A receiving finger is provided with a first end and a second end. The receiving finger is designed that it can engage into the hollow body molding. The outside shape of the receiving finger substantially corresponds to inside shape of the hollow body molding so that the receiving finger ( | 02-24-2011 |
| 20110027411 | Decompression sprue bush and decompression machine nozzle - The present invention concerns a transfer element ( | 02-03-2011 |
| 20100297287 | Mould cavity with decoupled cooling-channel routing - A cavity member for a mold cavity structure for the production of hollow body moldings, wherein the cavity member has a substantially hollow-cylindrical element, wherein a cooling passage is provided at the outside of the hollow-cylindrical element. To provide a cavity member which is simple to manufacture and which permits more effective cooling of the cavity member it is proposed in accordance with the invention that there are provided one or more guide elements for forming the cooling passage, wherein the guide elements and the hollow-cylindrical element are in the form of separate parts. | 11-25-2010 |
| 20100007048 | METHOD FOR THE PRODUCTION OF A MULTI-LAYER PREFORM AND NOZZLE THEREFOR - A melt feed device for an injection molding apparatus having at least one nozzle element connected both to a first hot runner and a second hot runner for feeding both the first melt and the second melt into an injection molding mold. The nozzle has three substantially concentrically arranged feed passages, wherein the innermost and the outermost feed passage are in communication with the first hot runner and the central feed passage is in communication with the second hot runner. A closure element is provided that can be reciprocated between a first position in which the closure element closes all feed passages, a second position in which the closure element opens the outermost feed passage but closes the other two feed passages and a third position in which the closure element opens all feed passages. The invention also includes process and molds using the device. | 01-14-2010 |
| 20090324770 | Bottom Insert With Heat Insulation - A bottom insert for a mold cavity for the production of moldings of plastic material. The mold cavity has a main body with a hot side which has a recess for receiving molten plastic material under pressure and a cold side having a recess, the inside contour of which is intended to come into contact with the molding to be produced and to shape the outside contour thereof. A gate ( | 12-31-2009 |
| 20090304848 | Two-Piece Bottom Insert - A bottom insert for an injection mold, which insert is of a two-part configuration having a hot part which has a recess of the hot side and a cold part which has a recess of the cold side, wherein the cold part is arranged at least partially within the hot part so that the hot part at least portion-wise surrounds the cold part. The two parts of the bottom insert are preferably separable and the. hot part preferably has an opening in opposite relationship to the recess of the hot side for receiving the cold part. Further, the cold part and the hot part are desirably sealed off relative to each other, desirably by O-rings. In general, all surfaces which are provided for contact with the molding to be produced are arranged at the cold part. An insulating coating, an insulating membrane and/or a spacing element is desirably provided at the contact surface between the hot part and the cold part. | 12-10-2009 |
| 20090212459 | Method and System for Post-Treating Preforms - The invention concerns a system for the post-treatment of preforms ( | 08-27-2009 |
