Method of manufacturing a wellbore downhole tool, including providing a pre-polymer resin and processing the pre-polymer resin. Processing the pre-polymer resin includes applying directed energy from a directed energy source such that the pre-polymer resin is at least partially polymerized to form a polymer seal of the wellbore downhole tool, the polymer seal having one of more mechanical properties that differ along one or more dimensions of the polymer seal. A downhole tool for use in a wellbore, the downhole tool including a polymer seal. The polymer seal is a continuous single monolithic piece, includes polymer structures having a polymer chain including same types of monomers that are bonded together, and the polymer structures are altered along one or more dimensions of the polymer seal and one of more mechanical properties of the polymer seal differ along a same corresponding one of the or more dimensions of the polymer seal.

A method of controlled deposition of a liquid or semi-liquid sealant material is disclosed herein. The method includes the use of a template which allows the sealant material to be deposited as a bead onto a surface of a specific machine part. The placement and shape of the bead, including route and volume, can be controlled using the template. The placement and shape of the bead can correspond to features of the specific machine part. A machine repair kit configured for repair or assembly of the specific machine part can include the template and a sealant material compatible with the template.

The present invention relates to the field of forming technologies for rubber sealing ring blanks, and more particularly to an automatic forming method and device for a rubber sealing ring blank. A cutting blade is fixedly connected to the surface of a blank forming assembly; an equipment body II is fixedly connected to a sliding table die set; a supporting rod II is fixedly connected to the surface of the equipment body II; a blank box is fixedly connected to the inner side surface of the supporting rod II; and a blank spool is fixedly connected to the tail end of a long blank strip. The method and device disclosed by the present invention have the advantages that the automation degree is high, and the long blank strip conveyed from the blank spool passes through guide wheels and a guide groove and is automatically pressed into a ring through the combined action of the blank forming assembly and the cutting blade. According to this patent technology, feeding is performed by means of continuous introduction of the blank strip; and automatic formation of the blank ring is achieved through the action of an automation assembly. Except for a process of replacing the blank spool after the long blank strip of the blank spool is used up, the other processes are all completed by the machine, such that the automation rate is high.

Methods of fabricating seal caps using three-dimensional printing are disclosed. The seal caps are useful for sealing fasteners.

An assembly to form a seal around a conduit. The assembly includes a mold with multiple sections that mate together to form a cavity that extends around the conduit. A retaining plate is configured to mount to the conduit and positioned in contact with the mold. A knuckle has a clamshell configuration with a first jaw and a second jaw that are pivotally connected together by a connector and movable between an open position and a closed position. A spring clip is positioned between the knuckle and the retaining plate with the spring clip configured to apply a force to maintain the retaining plate in contact with the mold.
