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.

The manufacturing method of the sheet having the needle-like protruding portions includes: preparing a mold including needle-like recessed portions, and a solution supply device including a slit-like opening formed at a nozzle distal end portion; supplying a solution from the solution supply device to the mold in a state that the nozzle distal end portion is pressed to a front surface of the mold, and filling the solution in the needle-like recessed portions; and moving the solution supply device relatively to the mold in a state that the nozzle distal end portion is brought into contact with the front surface of the mold, and, as a hardness distribution in a thickness direction of the mold, an average value of a Young's modulus at a part within 40 μm from the front surface of the mold is 1.9 MPa or higher and 100 MPa or lower.

The rotational molding system comprising an internal air cooling system disposed on the mold and configured for one or more of selectively controlling air flow into or out of a cavity of the mold for actively cooling an interior surface of a part, pressurizing the cavity of the mold, allowing pressure equalization, or venting of off-gases. A first thermocouple and a second thermocouple disposed within the cavity to measure a temperature at the exterior surface of a part and the mold cavity. A control system in electronic communication with both said first thermocouple and said second thermocouple, may selectively operate the internal air cooling system to maintain the temperature of the cavity and the part's outside surface substantially the same. The mold and/or the oven containing the mold may be disposed for rotation about a first axis and a second axis during the rotational molding process.

A cushion for a hot tub or spa is molded in a rotational molding process. The cushion includes a decorative outer surface made from a plastic material (e.g., an outer wall and side walls, etc.). The cushion includes a a back surface for interfacing with a hot-tub shell or spa shell with at least one projection extending from the back surface towards the decorative surface. The at least one projection is for supporting the force of an object that is resting on the cushion. The cushion if formed in a rotational molding process.
