摘要:
A manufacturing apparatus for manufacturing extruded parts having microstructures comprising: a support structure; a hopper carried by the support structure for receiving feedstock; an extrusion chamber operatively associated with the hopper for receiving the feedstock from the hopper and melting the feedstock above a feedstock melting temperature; a die carried by the support structure having die microstructures disposed on an inner surface of the die, the die microstructures having a plurality of microfeatures each having an upper surface and a lower surface, the melted feedstock being forced through the die to produce an extrudate having extrudate microstructures; and, a cooling assembly wherein the extrudate microstructures of the pre-cooled extrudate have larger physical dimensions than that of the extrudate microstructures of the cooled extrudate.
摘要:
A method of manufacturing a production part having microstructured features comprising the steps of fabricating a microstructured prototype having microstructured features, manufacturing a microstructured intermediate from the microstructured prototype so that the microstructured intermediate carries a negative of the microstructured features, attaching the microstructured intermediate to a manufacturing tool thereby providing microstructured features on a manufacturing tool, providing feedstock containing material from the group comprising of: metal, ceramic, binder, and any combination of these and manufacturing the production part from the feedstock, using the manufacturing tool and using a process from the group consisting of: compression molding, roll forming, stamping, embossing, extrusion injection molding, and any combination of these.
摘要:
Described herein are casting and molding methods useful for making microstructured objects. By including a plurality of microfeatures on the surface of an object, other characteristics may be imparted to the object, such as increased hydrophobicity. Some of the casting and molding methods described herein further allow for manufacture of objects having both microfeatures and macro features, for example microfeatures on or within macro features or selected macro feature regions.
摘要:
A process for forming a multilayer ceramic capacitor. The process includes depositing a ceramic precursor on a substrate and an electrode ink in a predetermined pattern on the ceramic precursor to form a green sheet. The electrode ink has an adhesion promoter incorporated therein. The green sheet is overlayed with at least one second green sheet to form a layered green sheet which is then fused under pressure.

A process for forming a multilayer ceramic capacitor. The process includes forming a ceramic precursor layer and depositing an electrode precursor in a predetermined pattern on the ceramic precursor layer to form a first patterned sheet. A flowable ceramic precursor is applied to the first patterned sheet. At least one second patterned sheet is applied to the first patterned sheet to form a layered patterned sheet and the layered patterned sheet is laminated.
