| 20100303950 | CROSS-LINKED THERMOPLASTIC POLYURETHANE/POLYUREA AND METHOD OF MAKING SAME - A process for forming a cross-linked thermoplastic polymer is disclosed herein. The cross-linked thermoplastic polymer is formed by heating a first mixture containing a thermoplastic urethane base material, a monomeric diisocyanate comprising between 1 to 10% of the total weight of the first mixture, and a second mixture of a first diamine and a second diamine comprising between 1 to 10% of the total weight of a total reaction product. The heated first mixture, which is flowable, is injected into at least one injection molding device, with the second mixture injected at predetermined intervals to create a homogeneous reaction product. | 12-02-2010 |

| 20120107444 | FORMING DIE ASSEMBLY FOR MICROCOMPONENTS - A forming die assembly for microcomponents includes a forming die, a plunger, and a punch. The forming die is formed with an outer die, an inner die, a storage portion formed at the inner die, and a punch hole formed at the inner die. The inner die slidably inserted into the outer die forms a part of a cavity between the inner die and the outer die. The storage portion stores a raw material with a metal powder and a binder having plasticity. The punch hole connects the cavity and the storage portion and forms a gate therebetween. The plunger slidably inserted into the storage portion fills the raw material stored in the storage portion into the cavity through the punch hole. The punch is slidably inserted into the plunger, and it closes the gate and compresses the raw material in the cavity. | 05-03-2012 |
| 20120107445 | FORMING DIE ASSEMBLY FOR MICROCOMPONENTS - A forming die assembly for microcomponents includes a forming die, a plunger, and a punch. The forming die is formed with a cavity, a storage portion for storing a raw material with a metal powder and a binder having plasticity, and a punch hole that connects the cavity and the storage portion so as to form a gate therebetween. The plunger is formed so as to be slidably inserted into the storage portion and to fill the raw material stored in the storage portion into the cavity through the punch hole. The punch is slidably inserted into the plunger in the sliding direction of the plunger and opens and closes the gate by reciprocatory sliding. The punch closes the gate and compresses the raw material in the cavity into a green compact by sliding in the direction of the cavity. | 05-03-2012 |
| 20130071510 | INJECTION DEVICE IN MOLDING MACHINE - A injection device in molding machine is capable of efficiently heating and melting a plurality of charged pellets in a short period of time, and injecting a melting resin with superior quality. | 03-21-2013 |

| 20140065257 | INJECTION MOLDING APPARATUS - An injection molding apparatus includes a heating device heating reinforcing fiber assemblies, an injection cylinder to which a thermoplastic resin and the reinforcing fiber assemblies are supplied, a first screw compressing and kneading the thermoplastic resin, a second screw fibrillating the reinforcing fiber assemblies and dispersing reinforcing fibers obtained by the fibrillation into the thermoplastic resin, a resin supply portion supplying the thermoplastic resin to a void formed between the injection cylinder and the first screw, and a reinforcing fiber supply portion supplying the reinforcing fiber assemblies to a void formed between the injection cylinder and the second screw. The second screw serves as one of a non-compression screw and a low compression screw including a low compression ratio by which the reinforcing fibers are inhibited from being excessively broken at a time of receiving a shearing force generated by a rotation of the second screw. | 03-06-2014 |
| 20150050382 | INJECTION MOLDING APPARATUS - A small sized injection molding machine by which a molded product can be produced with a desired level of precision with simple control. An injection molding machine with: a longitudinal injection cylinder to which stick-shaped molding materials are sequentially supplied in line from the upper side, the lower end of which is formed into a nozzle shape, and the lower side of which is constituted by a material having a good heat retaining property; a heater which heats the lower portion of the injection cylinder; and a pressing shaft which presses the stick-shaped molding materials downward. When the stick shaped-molding material located at the uppermost side is pressed by the pressing shaft, the molding material located at the lowermost side which has already been completely melted, is injected into a cavity, and the heat from the heater is transmitted to the die side through a nozzle touch portion. | 02-19-2015 |
