Pierced thermal interface constructions including a thermal interface material (TIM) structure comprising: a TIM sheet comprising a plurality of piercings, where each of the plurality of piercings comprises a cavity and displaced material, and where the displaced material from each of the plurality of piercings protrudes away from the TIM sheet.

A punching/perforation machine creates a predefined punching/perforation pattern in a material that is supplied in a direction of travel. The machine comprises a punching/perforation tool that includes an upper tool part which can be moved in a direction of stroke and which is equipped with a plurality of punching dies/perforation needles that are arranged in a predefined grid in a transverse direction and can be moved by a pressure beam that is operatively connected to a drive unit via a control device in order to produce a punching/perforation stroke. The material is supplied between the upper tool part and a lower tool part. The material is placed or clamped in a frame mechanism. The punching/perforation machine includes a frame accommodation/connection device for accommodating/connecting the frame mechanism, and the frame mechanism containing the material is supplied between the upper tool part and the lower tool part.

The invention relates to a perforating device for thermoplastic plates, which relates to the technical field of a plate processing device. The device includes an electromagnetic chuck, one side of the electromagnetic chuck is connected with the driving member, the other side of the electromagnetic chuck is connected with a mounting plate and a spike. When the electromagnetic chuck is powered on, the spike is attracted below the mounting plate by an electromagnetic force generated by the electromagnetic chuck. A damper is arranged below the mounting plate, the thermoplastic plate is fixed by the damper, and a heating system is also provided to heat the thermoplastic plate. As the electromagnetic chuck is powered on or off, the spike can be attracted in or separated from the mounting plate, respectively. Therefore, the perforating device can make a new plate be pierced during the cooling and curing process of the perforated plate.

An apparatus and a method for automatically applying, without the intervention of an operator, rubber elements on a die-cutter during the manufacturing step thereof, are described. The apparatus comprises a manipulator, preferably a robotic arm, and a needle gripper. The gripper withdraws the water jet pre-cut rubber elements from a sheet with double-sided adhesive tape, and places them one by one at the point provided for by the working program.
