A resin molding apparatus capable of suppressing an occurrence of defects related to resin filling. The resin molding apparatus includes: a molding mold which forms a cavity; a pot which is arranged in the molding mold and is capable of accommodating a resin material, and in which an opening portion opening directly to the cavity is formed; and a plunger which is arranged to be slidable in the pot, and transfers the resin material accommodated in the pot toward the cavity via the opening portion by extruding the resin material. An inner diameter of the opening portion is formed to be the same as an outer diameter of the plunger or larger than the outer diameter of the plunger.

A method includes: providing a mold having a plurality of mold cavities, wherein each mold cavity is bounded by a plurality of faces joined along common edges; filling at least some of the mold cavities with a sol-gel composition that includes a release agent dispersed therein; at least partially drying the sol-gel composition thereby forming shaped ceramic precursor particles; calcining at least a portion of the shaped ceramic precursor particles to provide calcined shaped ceramic precursor particles; and sintering at least a portion of the calcined shaped ceramic precursor particles to provide ceramic shaped abrasive particles. A sol-gel composition, shaped ceramic precursor particles, and ceramic shaped abrasive particles associated with practice of the method are also disclosed.

A device for pastillating a flowable product, in particular a melt. The device has a revolving belt and a drop former, and the drop former deposits product drops on an upper run of the belt. The product drops, in the course of transportation on the upper run of the belt, solidify to form pastilles, and an arrangement for wetting the belt with a liquid release agent is provided upstream of that region in which the product drops are deposited on the belt. The release agent prevents or reduces the adhesion of the product drops to the belt, and a proportional metering pump is provided for continuously mixing the release agent from at least two liquid components during the operation of the device.
