A method for forming a protective film on an electronic module includes: placing the electronic module and a protective material placed on the electronic module in a chamber; performing a first heating procedure on the protective material in the chamber, and performing a first pressure boosting procedure, wherein a pressure in the first pressure boosting procedure is greater than 1 atmosphere; after softening the protective material, maintaining the first heating procedure, and performing an oscillating decompression procedure on the chamber, wherein the oscillating decompression procedure includes alternately changing pressures in the chamber between multiple low pressures less than 1 atmosphere; maintaining the first heating procedure, and performing a second pressure boosting procedure on the chamber, wherein a pressure in the second boosting procedure is less than that of the first boosting procedure and greater than 1 atmosphere; and performing a second heating procedure on the protective material in the chamber to form the protective film covering the electronic module.

A lyophilization container includes a first section having a first layer, a second layer aligned with the first layer, and a cavity defined by the alignment of the first and second layers, where at least one of the first and second layers is preformed to have a three-dimensional shape. A lyophilization fixture includes a base member and a lid member. The lid member is movable between a first position and a second position relative to the base member. The base member and lid member together define a housing that receives at least a portion of a lyophilization container.

A vacuum forming apparatus includes a die set including an upper die and a lower die. The upper die is configured to move in a horizontal direction from a normal position at which the upper die is initially set. The lower die includes a suction channel through which a vacuum is applied to a cover. The lower die is opposite the upper die that is at the normal position. The upper die is configured to move from the normal position to a space lateral to the lower die so as not to face the lower die after the die set is opened, and return to the normal position before the die set is closed. The lower die is configured to move downward during opening of the die set and upward during closing thereof. The die set is configured to form the base member with the cover into a predetermined shape.

An artist palette having a tray with an upper surface, a plurality of recessed wells positioned in the tray, an aperture in an edge of the upper surface of the tray providing a place for a painter to hold the tray, a drip ledge groove positioned on a periphery of the upper surface of the tray including a first upwardly extending edge useful for removing excess paint and water from a paintbrush, and wherein the drip ledge groove serves to hold paint or water that has been removed from the paintbrush.

A thermoforming device is described. It relates to a mold assembly including a first and second mold, and to a mold that can be used in a thermoforming device. It also relates to a method for thermoforming a product. The thermoforming device is characterized in that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element, and that the second pre-stretcher is at least partially and moveably arranged in a second mold body. A movement relative to the second mold body and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element, can be individually controlled, and the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element.
