An apparatus for compacting yard waste is disclosed. The apparatus comprises a shaft and a base adapted to crush yard waste. The apparatus is assembled by releasable coupling of the shaft and the base.

A piston includes: a base body; a sealing ring provided at an outer peripheral surface of the base body and configured to slidingly contact an inner peripheral surface of a container; a pressing body provided at one side of the base body in a non-hermetical state with respect to the container, the one side being close to a fluid; and a supporting member supporting the pressing body in a state where the pressing body is separated from the base body. The base body includes an air discharge hole through which an inside and outside of the container communicate with each other, the inside and outside of the container being sealed by the sealing ring. The pressing body can approach and separate from the base body between a first position at which the pressing body opens the air discharge hole and a second position at which the pressing body closes the air discharge hole. The pressing body is supported by the supporting member at the first position and moves to the second position by force applied from the fluid in the container.

A method for coating stainless steel press plates includes preparing the stainless steel press plate for coating and coating the stainless steel press plate with a diboride doped with 1%-5% by weight aluminum to produce a diboride-aluminum coating. The step of coating includes applying the diboride-aluminum coating to a stainless steel press plate using a magnetron sputter coating system.

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.

A press machine has a body, a lower pressing assembly, and an upper pressing assembly. The body has a first driving device, a second driving device, at least one first supporting rod, and at least one second supporting rod. The at least one first supporting rod is rotatably connected to the first driving device. The at least one second supporting rod is rotatably connected to the second driving device. The lower pressing assembly is movably mounted with the at least one first supporting rod of the body. The upper pressing assembly is movably mounted with the at least one second first supporting rod of the body, and is able to move toward the lower pressing assembly.

A hot-press device includes: a heating furnace; a pair of punches which includes an upper punch and a lower punch provided in the heating furnace and vertically facing each other; a lower press ram which is connected to a lower surface of the lower punch; an upper press ram which is connected to an upper surface of the upper punch; and a pressing device which is connected to any one or both of the lower press ram and the upper press ram and presses the punch so that the pair of punches are close to each other, in which the lower press ram and/or the upper press ram includes a plurality of individual press rams which are disposed at intervals, each individual press ram having one end coupled to the pair of punches.

The present disclosure provides a pressing device which includes: at least two floating heads which are arranged side by side; a positioning member connecting with each floating head and defining a position of each floating head; a cover plate positioned above each floating head; and elastic members, each elastic member being provided between the cover plate and the corresponding floating head so as to make the cover plate slide up and down relative to each floating head. The pressing device can be adapted to a step type cell or a step type battery having a certain tolerance in thickness and can ensure that every step surface of the step type cell or the step type battery is uniformly pressed, thereby improving the quality of the battery.

Systems and methods for pressing a door assembly involve one or more die sections installed in a press, wherein the die sections each have a raised section that contacts and supports a recessed panel portion of a door skin of the assembly during the pressing operation to facilitate crushing of portions of a core of the door assembly that underlie the recessed panel portion of the door skin. The die sections may be made of plastic and readily changed out for different sizes or styles of doors.

A joining punch for a joining device for producing a joining connection, in particular an adhesive connection, between a first joining part, for example a cover glass, and a second joining part, for example a housing, has at least one force-receiving part to which a contact force can be applied and having at least two pressing parts for applying pressure to the first joining part. The at least two pressing parts are arranged and/or formed independently of one another on the joining punch in such a manner that they are tiltable relative to the force-receiving part. The joining punch is embodied in a joining device. The two joining parts can be pressed together according to a nominal distribution of the forces or pressures, in particular uniformly using the joining device. Unevennesses and deformations of the joining parts, in particular of the first joining part, can be compensated.

Disclosed is a method for creating a textured press plate. Initially, a mask may be applied to a surface of a press plate. This mask typically corresponds to a desired physical surface structure. Thereafter, the masked surface of the press plate is processed to obtain the desired physical surface structure. Thereafter, various techniques may be used to create differing degrees of gloss in differing portions of the surface of the press plate. For example, matting may be used to decrease the degree of gloss of a portion of the surface, and polishing may be used to increase the degree of gloss of a portion of the surface.
