摘要： A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.

摘要： The present invention teaches an assembly and corresponding method for producing a plastic part having a sandwich mold including an upper half and a lower half. Each of the halves exhibit an opposing inner face which, upon assembling, collectively define an interior cavity corresponding to a configuration of the part to be produced. An insert sheet of a polymer material (typically a thermoplastic at room temperature) is placed upon a lower of the mold halves and prior to assembling the upper mold half. A heat source is communicated to the closed mold to cause the insert sheet to melt into the cavity. A cool source is subsequently communicated to the closed mold to cause the thermoplastic to harden within the cavity and prior to opening of the mold and removal of the finished part.

摘要： Provided is a method of producing a battery separator using surface modification treatment, which produces the battery separator by a dry process, satisfies air permeability and puncture strength properties required in the battery separator, and improves the thermal shrinkage and wettability of the battery cell, thereby appropriately responding to the trend for high-capacity and compact batteries. The method comprises: forming an unstretched sheet; subjecting the unstretched sheet to heat forming; cold-stretching the sheet subjected to the heat forming, thereby obtaining a cold-stretched film; hot-stretching the cold-stretched film by first hot stretching and second hot stretching; and heat-setting the film subjected to the second hot stretching, wherein corona discharge treatment is performed between the first hot stretching and the heat setting.
