The present disclosure provides methods of reducing center shifting of golf ball components, which, in turn, improves concentricity of the resulting golf balls. The methods include extruding a golf ball component material through an extruder to form an extrudate having a first temperature, cutting the extrudate at a second temperature to form a component prep, and molding the component prep into the golf ball component. The preps formed by the methods of the present disclosure include surfaces having reduced or no concavity.

A method for producing a rubber-plastic composite, including the steps of (a) shaping an unvulcanized elastomer, (b) partially vulcanizing the shaped elastomer at a temperature of at least 140 C. up to a degree of vulcanization in the range from 10% to 40%, (c) cooling the partially vulcanized elastomer to a temperature of less than 100 C. within less than 20 minutes, (d) overmolding the partially vulcanized elastomer with a plastic, and (e) heat treating the partially vulcanized elastomer overmolded with a plastic at a temperature in the range from 100 C. to 170 C. for a duration of from 5 minutes to 5 hours to complete the vulcanization and form a rubber-plastic composite. The method further relates to a rubber-plastic composite obtainable by the method according to the invention and also to a shoe comprising the rubber-plastic composite obtainable by the method according to the invention.

Cartilage fibers and implants made therefrom are disclosed, with and without cartilage particles. Methods for making the cartilage fibers and the implants containing them are also disclosed. The implants may be pre-shaped and may be reshapable and provide good shape retention and little swelling when placed into a cartilage defect.
