A method of applying fibrous material to a medical device component involves coupling a medical device component a holder device, rotating a reservoir device containing a liquid polymeric solution to expel at least a portion of the liquid polymeric solution from an orifice of the reservoir device, the expelled at least a portion of the liquid polymeric solution forming one or more strands of fibrous material in a deposition plane, and rotating the holder device at least partially within the deposition plane to apply at least a first portion of the one or more strands of fibrous material to one or more surfaces of the medical device component, thereby forming a fibrous covering on the one or more surfaces of the medical device component.

Systems and methods for protecting threads of metal pipes while coating the metal pipes with a protective coating are disclosed herein. Innovative metal couplings are used to protect the threads while a protective coating is applied to the metal pipes. The couplings are reusable and result in multiple efficiency improvements over previous methods and systems. Benefits include elimination of plastic caps and reduced waste, improved flowthrough in the powder coating process, more efficient thermo transfer in the thermal chamber, and an increase in the overall capacity of the powder coating operation.

The invention provides a method for preparing tissue-adhesive sheets that may suitably be applied as an implantable haemostatic or sealing construct during surgical procedures, said method comprising: providing a fibrous sheet comprising a three-dimensional interconnected interstitial space; providing reactive polymer particles comprising a water-soluble electrophilic polymer carrying at least 3 reactive electrophilic groups that are capable of reacting with amine groups in blood under the formation of a covalent bond; placing the fibrous sheet and the reactive polymer particles between two electrodes; simultaneously subjecting the fibrous sheet and the reactive polymer particles to an electric field of 0.1 to 40 kV/mm to impregnate the interconnected interstitial space of the fibrous sheet with the reactive polymer particles.

An electric field is formed between a substrate and a screen by applying a first voltage to the substrate and applying a second voltage to the screen. Coating powder is introduced into the electric field through the screen. An electrode is manufactured by causing the coating powder to adhere to the substrate. The first voltage has a polarity opposite to a polarity of the second voltage. When the coating powder passes through the screen, the coating powder comes into contact with the screen to apply a charge to the coating powder. The coating powder flies in the electric field by an electrostatic force to reach the substrate. An angle between a flight direction of the coating powder and a vertically downward direction is 90 degrees to 270 degrees.

Embodiments simulate electrostatic painting on a real-world object. An embodiment begins by receiving an indication of paint deposition rate and an indication of maximum paint accumulation for a given real-world robotically controlled electrostatic paint gun. Next, paint deposition of the given real-world robotically controlled electrostatic paint gun in a virtual environment is represented which includes, for a subject time period, computing total paint accumulation (electrostatic and direct) on a given surface element of a model representing the real-world object. In turn, a parameter file is generated that includes parameters accounting for the determined total paint accumulation for the given surface element, where the generated parameter file enables precision operation of the given real-world robotically controlled electrostatic paint gun to paint the real-world object.
