A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

An apparatus, kit, and methods for forming a bead between bead-forming blocks having internal bead-forming channels are provided. The bead-forming channels of adjacent bead-forming blocks are slidably engaged to manipulate a measured amount of modeling compound between the bead-forming blocks and within an internal space between the opposing channels. In one embodiment, the bead-forming blocks maintain orientation with respect to an axis of travel based on a block guide. Further, the measured amount of modeling compound is determined using an integrated measuring feature coupled to at least one of the pair of bead-forming blocks. The internal volume of an integrated measuring feature corresponds to a threshold amount of modeling compound for manipulating between the pair of blocks and forming a bead while contacting at least a portion of the mated bead-forming channels. In further aspects, a molded bead may be coated with a multicomponent bead-coating mixture. Multi-component bead-coating mixtures and methods of using thereof are provided.

The present disclosure is relates to a TPU ball structure and a manufacturing method thereof. The TPU ball structure includes a ball bladder layer, a yarn layer and a surface layer. The ball bladder layer is made of TPU material. The yarn layer is made of TPU material, and the yarn layer is disposed to cover the ball bladder layer. The surface layer is made of TPU material, and the surface layer is disposed to cover the yarn layer. The above layers of the TPU ball structure are made of TPU material to satisfy a requirement for environmental protection, and are recyclable. There is no need to use adhesive to adhere the above layers of the TPU ball structure. Therefore, the peeling strength between the layers of the TPU ball structure can be increased so that the whole peeling strength of the TPU ball structure can be increased.

A method of producing toy balls for pets, including: manufacturing distorted sphere balls with an opening in the distorted area using injection molding; sealing the opening of the distorted sphere balls to form uni-body sphere-shaped balls. The material used in the production of these toys can be rubber, thermoplastic elastomers, or thermoplastic rubber. This method allows to manufacture toy balls with no detached parts in the case of broken joints when the balls are chewed or torn apart by the pets. Thus, the ball can help to keep the pets from endangering themselves by swallowing detached parts of pet toy balls.

Provided is a method for manufacturing an exercise ball which is made by using a pasted ball such as a soft leather ball and which has a lower impact value compared to a conventional yarn-wound ball. The exercise ball comprises a spherical hollow rubber bladder (2) in which compressed air is sealed, and a yarn-wound reinforcement layer (3) formed by evenly winding a filament yarn around the surface of the rubber bladder, wherein the exercise ball is characterized in that nylon filament yarn, obtained by hard twisting two 30-50 denier nylon filaments 1-a, 1-b in a single-direction twist is used as a winding yarn (1).
