Method for supplying resin, method for manufacturing resin molded product, and resin molding apparatus
Provided a method for supplying a resin by which appropriate replacement of a cartridge enables resin supply to be performed appropriately. The method for supplying a resin includes: a primary resin supplying step of supplying a liquid resin contained in a first cartridge to a supply target, the first cartridge having a remaining amount of liquid resin smaller than a target supply amount appropriate for one-time resin supply to the supply target; a cartridge replacing step of replacing, after the primary resin supplying step, the first cartridge with a second cartridge already subjected to dripping out; and a secondary resin supplying step of supplying a liquid resin contained in the second cartridge to the supply target after the cartridge replacing step.
LIQUID COLOR MANAGEMENT METHODS
A method for managing the supply of liquid color to a process machine utilizes an electronic memory device connected permanently to a container of liquid color and an electronic memory controller that interacts with the electronic memory device, preferably wirelessly over the Internet.

RESIN SUPPLY SYSTEMS
Resin supply system in which resin material is stored in a pouch (120) in a degassed state ready for use. The pouch comprises a body portion (122) forming a reservoir for resin material and a connector portion (125) in fluid communication therewith. The connector portion includes an outlet (127) which is configured to be connected to an injector head (180) of an injector assembly (100), the injector head being connectable to a mould by means of connecting tubing to provide a resin supply (130) thereto. The pouch is configured to be mountable in a housing (110) of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber (115) of the housing. The application of pressure by a piston (150) moving in a direction (155) transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.
Manufacturing of small film strips
The present invention relates to methods and apparatuses for forming films. In particular, the present invention relates to the formation of films on a substrate via the use of individual pumps to deposit individual wet film products onto a substrate. A method of forming film products includes: providing a reservoir housing a film forming matrix, pumps in association with the reservoir, and orifices; feeding the wet film forming matrix from the reservoir to the pumps; dispensing the film forming matrix from each of the pumps through an orifice; and depositing wet film products onto a substrate. An apparatus for forming film strips includes: (a) a reservoir for housing a film forming matrix; (b) pumps associated with the reservoir; (c) a plurality of orifices, with each orifice being associated with a pump; (d) a substrate; and (e) a means for moving the substrate through the apparatus.

Method for Molding Plastic Materials
A method for material handling and mold filling is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The method therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A method of using a multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.

Self-cleaning gravimetric and volumetric dosing apparatuses
A self-cleaning dosing apparatus includes a material hopper for containing pellets of material, a feed screw, a first material outlet through which pellets of material fall by gravity onto a first end of the feed screw for the feeding of pellets to a process machine. A second material outlet is located beneath the first end of the feed screw, with a slide gate blocking the second material outlet. A pneumatic piston is provided for pulling the slide gate to unblock the second material outlet, and a Venturi pump is located under the second material outlet for pulling pellets through the second material outlet when the slide gate is opened.
Supply device for supplying pasty masses
The invention relates to a feeding apparatus for feeding pasty masses, in particular silicone, to an injection molding machine, having a pressing cylinder which receives the pasty mass, and a pressing plunger which is arranged axially in said pressing cylinder and presses the pasty mass out of a squeezing nozzle of the pressing cylinder. It is an object of the invention to avoid operational interruptions for cleaning work in the case of a feeding apparatus of this type and to avoid material losses within the feeding apparatus in the case of the successive use of different pasty masses. In order to achieve said object, the invention proposes that the pressing cylinder is configured as a cartridge (3) which contains the pasty mass, consists of a polymer, and can be inserted exchangeably into a supporting housing (2) which supports the cartridge on all sides and is connected to an axial actuating drive (5) for the pressing plunger (3d) which is situated in the cartridge.
