Publication number: 20110086125Abstract: An injection drive apparatus for injection molding machines is revealed. Liquid material is fed into a mold smoothly by a material feeding screw of a material feeding mechanism. Then a reaction force is generated to push the material feeding screw when the material feeding hole is nearly full of the material. Thus the material feeding screw and the slide mechanism assembled therewith are pushed to move backward. Later the injection mechanism is driven by the slide mechanism to move and act on the drive screw. Thus the slide mechanism threaded with the drive screw is driven to push the material feeding screw moving forward and squeezing the material for injection molding. Therefore, the load of the motor is reduced dramatically and the yield rate of the products produced by injection molding is increased due to the two-stage action-feeding of the material and squeezing of the material for injection.Type: ApplicationFiled: October 9, 2009Publication date: April 14, 2011Inventor: Jin-Hsiang Wang

Publication number: 20040262813Abstract: Systems and methods for injection molding polymeric materials are provided. The systems and methods use a supercritical fluid additive. In some cases, the use of supercritical fluid additive enables formation of molded articles with low clamping forces and/or low injection pressures. Low clamping forces and/or low injection pressures may reduce the cost of a system designed to form a particular molded article. In some embodiments, the systems may include a control system that controls the operation of one or more components of the system (e.g., the extruder or the supercritical fluid additive introduction system). The systems and methods are suitable for forming polymeric foam articles including microcellular material articles.Type: ApplicationFiled: November 4, 2003Publication date: December 30, 2004Applicant: Trexel, IncorporatedInventors: David E. Pierick, Levi A. Kishbaugh, Jingyi Xu, Juan C. Cardona, Himanshu R. Sheth, Kevin J. Levesque, Jeffrey L. Ng, Roland Y. Kim

Publication number: 20040202743Abstract: A process and apparatus for plastics injection moulding comprises injecting a quantity of molten plastics material into a mould cavity (30) and injecting pressurised gas (52) or pressurised liquid into the plastics material in the mould cavity. After holding the pressure of the gas or liquid on the plastics material in the mould cavity for a period of time in order to apply a packing pressure to the plastics material, a portion of the molten plastics material is expelled into one or more secondary cavities (32) or expelled back into the barrel (22) of the injection moulding machine. The step of injecting the plastics material may be effected with or without packing of the plastics material prior to the injection of the pressurised gas or liquid.Type: ApplicationFiled: January 9, 2004Publication date: October 14, 2004Inventor: Terence Colwyn Pearson

Publication number: 20040105910Abstract: An injection molding machine includes an actuating drive in form of an electromotive spindle drive and an energy storage device associated with the spindle drive. The energy storage device stores kinetic energy and can include two counteracting compression spring assemblies. The energy storage device is hereby loaded, as the spindle drive moves to a first end position, and unloaded, as the spindle drive moves in opposite direction to a second end position, wherein unloading of the energy storage device is accompanied by a power boost of the electric motor, and wherein the first force is equal to the second force at an equilibrium location distal from the end positions of the spindle drive.Type: ApplicationFiled: October 20, 2003Publication date: June 3, 2004Applicants: DEMAG ERGOTECH GMBH, L & T-DEMAG PLASTICS MACHINERY PRIVATE LIMITEDInventors: Georg Michael Ickinger, Kittappa Gowda Harish, Mangalasseril Saju, Shanmuaham Sivakumar, Mathrubootmam Kumar, Anand Sukumaran Vivek

Publication number: 20030054067Abstract: A feeding system (10) for epoxy mould compound (EMC) pellets which has a supply bowl (12) situated outside the clean environment (24) of a conventional automatic moulding machine (26). A tube (16) extends from the supply bowl (12) to a buffer hopper (14) within the clean environment and which is located above the feeder bowl (28) of the automatic moulding machine (26). EMC pellets are transported through the tube (16) from the supply bowl (12) into the buffer hopper (14) via a vacuum suction system (34), (36) which is connected to the tube (16) in proximity to the buffer hopper (14). A counter air flow may be provided to slow the speed of the pellets as they enter the buffer hopper. Batches of the pellets accumulated in the buffer hopper (14) are periodically released into the feeder bowl (28) of the automatic moulding machine (26). The vacuum transportation system reduces dust from the pellets.Type: ApplicationFiled: September 20, 2001Publication date: March 20, 2003Applicant: ASM Technology Singapore Pte LtdInventors: Shu Chuen Ho, Teng Hock Kuah, Jie Liu
