    摘要： A ball sealer for hydrocarbon resource recovery, comprising: a generally spherical entire structure including at least two layers of a spherical core and a surface resin layer covering the spherical core, of which at least the surface resin layer comprises a polyglycolic acid resin; and having a diameter of at least about 25 mm (1 inch). The ball sealer is produced through a process comprising the steps of: disposing a spherical core by a support pin at a substantially central position within a mold cavity, injecting a surface resin comprising a polyglycolic acid resin into the cavity surrounding the spherical core, causing the support pin to retreat up to a wall surface of mold cavity in synchronism with a completion of the injection of the surface resin, and then hardening the surface resin. As a result, it is possible to produce a large-diameter ball sealer suitable for use in the hydraulic fracturing process (hydraulic fracturing) widely used for recovery of hydrocarbon resources by using a polyglycolic acid resin which is a biodegradable resin having good mechanical strengths and a good size designability at least as a surface-forming resin, through relatively simple steps and with good dimensional accuracy.

    摘要： The invention relates to a device (10; 10a) for encapsulating a component (1) with plastic material (2), comprising at least two tool parts (11, 12), which in a closed arrangement for encapsulating the component (1) form a receptacle (15) for the component (1), an injection channel (30) for supplying the liquefied plastic material (2) to the region of the receptacle (15), and a single retaining element (22) for positioning the component (1) in the receptacle (15), wherein the retaining element (22) can be moved in a first position for positioning the component (1) in the receptacle (15) and in a second position for preferably completely encapsulating the component (1) with the plastic material (2). According to the invention, the retaining element (22) holds the component (1) in the region of the receptacle (15) by means of form positive and/or clamping engagement.
