Abstract: A process for manufacturing an injection molded pet treat in a single, continuous and sterile production line, is disclosed. The process comprises inputting raw material in a storage container of the injection molding machine. The raw materials are dispensed from the storage container to a hopper of the injection molding machine. The quantity of the raw material in the hopper is maintained to a preset threshold value for continuous flow in the production line. The raw material is heated at a predetermined temperature to a semi-liquid state in an injection unit of the injection molding machine. Further, the heated raw material is injected into a thinner and uniform wall thickness mold pet treat design, thereby enabling rapid cooling of the molded pet treat. The molded pet treat is ejected to the injection molding discharge area, and conveyed to a packaging unit for packing the final pet treat product.

Abstract: A side gate nozzle assembly for a hot runner apparatus comprises a disc shaped base body, a probe member, a sealing insulator, and a shape memory alloy washer. The probe member with a probe channel extends from the base body. A molten molding material is received through a melt channel of the nozzle body, and allowed to pass through the probe channel to be transferred to a cavity of a cavity member. The shape memory alloy washer is positioned between the base body and the sealing insulator. The shape memory alloy washer distorts linearly to push the sealing insulator and the probe member according to change in temperature due to transfer of the molten molding material from the melt channel to the cavity member via the probe channel. The distorted shape memory alloy washer prevents leakage of the molten molding material from the melt channel, and the probe channel.

Abstract: The present invention relates to an ejection system for an injection molding apparatus comprising: a mold plate, housing a mold cavity consisting a molded material and a plurality of ejector pins arranged in such a way to extend sequentially through the mold cavity in order to push the perimeter of the molded material in a multi-stage sequence.

Abstract: The present invention relates to a perimeter ejector system for an injection molding apparatus comprising: a mold plate, housing a mold cavity consisting a molded material; and at least one lifting pin configured to extend through at least one corner or edge of the mold cavity, in order to eject the molded material off the cavity space. The lifting pin further comprises a push surface shaped to match the profile of the mold cavity, thus forming an integral part of the mold cavity.
