This invention discloses a production method of inflatable toy. The first step is to prepare hard PVC powder and soft PVC paste resin. The second step is injection moulding of embedded parts and grasp parts. The third step is preparation of slushing mold or rotational molding mold. The fourth step is shaping of soft PVC paste resin. The fifth step is cooling and demoulding and then air inflation for modeling. The sixth step is installation of grasp parts and inspection and testing of qualified products; in this invention, the secondary forming of hard PVC embedded parts made through injection moulding, are moulded in soft PVC rubber part itself through rotational molding or slush molding in the rotational molding mold or slush molding mold. And then, the grasp parts and embedded parts are firmly connected through buckle or screw. The design has solved the problem of location design of the circular handle, which is unable to be installed in parts other than the joint line through traditional PVC rotational molding mold or slush molding mold. It has perfectly realized the grasp function. In addition, the installation of formed ears or other injection-moulding parts guarantees no deformation of the parts, and this presents a good revivification of product design.

A magnet is embedded in a flexible elastic material, providing a means of temporarily connecting the flexible elastic material to ferromagnetic objects. A rigid cup provides a container for anchoring the magnet in the flexible elastic material. The cup also provides a structure to bind with the flexible elastic material. The magnet rests in the base of the cup, which extends past the surface of the material, allowing the magnet's forces to extend outside the base of the cup. The remainder of the cup resides within the material.

A composition comprising a high molecular weight, chromium catalyzed ethylene copolymer (also referred to as a polyethylene resin), a nucleating agent and zinc oxide.

An interlocking toy building block includes a first block body and a first magnet positioned therein a first distance from a first outer surface thereof to provide a first predetermined magnetic polarity to the first outer surface. When the first outer surface is brought into close proximity with a second outer surface of a second block body having a second magnet positioned a second distance therein and exhibiting a second predetermined magnetic polarity opposing the first predetermined magnetic polarity, the first outer surface is configured to mate with the second outer surface in an interlocking position. A potential magnetic force F.sub.m between the pair of magnets is determined by the formulation: F.sub.m=F.sub.o e.sup.−rd where F.sub.o is the initial force (i.e., no separation distance between magnets), and e.sup.−rd is the exponential function of the rate of decay “r” of the magnets and the distance “d” between the magnets.

The present invention discloses a system and method for making soft projectiles for use with toy and recreational firearms, the system and method comprising of a mold and a projectile material, the mold comprising of a first plate with one or more protrusions and a second plate with one or more cavities, the second plate mated with the first plate to form one or more soft projectiles.

The present disclosure relates to a method of manufacturing a model car body, including preparing a steel mold comprising a core plate with an inner core, a top plate and at least two side plates; attaching at least one pre-fabricated plastic block to a side of the inner core of the core plate; combining the core plate, the top plate and the at least two side plates with each other, wherein a cavity is formed among the top plate, the side plates, the inner core of the core plate and the at least one pre-fabricated plastic block; injecting melted plastic material into the cavity, wherein the melted plastic material is filled with the cavity and the at least one pre-fabricated plastic block is encased by the melted plastic material; solidifying the melted plastic so as to form the model car body, wherein the at least one pre-fabricated plastic block is integrated with the plastic model car body; separating the core plate, the top plate and the at least two side plates from each other; and releasing the model car body with the at least one pre-fabricated plastic block from the mold.

A method for beautifying a balsa wood model aircraft with a thermal shrink covering film, so that the balsa wood model aircraft with a thermal shrink covering film is obtained. This method makes a model aircraft colorful, reduces labor costs, improves the beautifying and painting effect of the model aircraft, and also improves the pneumatic performance of the model aircraft.

A method for manufacturing a composite part of polymer and metal utilizes a mold having a plurality of mold parts and forming a layer of metal on at least one inner or cavity-facing surface of the mold. Thereafter the mold parts are assembled to one another to form a mold cavity defined in part by the layer of metal. The mold cavity is then filled with resin material so that the resin material is in contact with the layer of metal. A curing or hardening of the resin material in the mold cavity is followed by an opening of the mold and the removal of a composite part having a metal shell or outer layer and a polymeric backing or inner layer.

An integrated multi-color animal chew toy and preparation process thereof, including selecting N types of rubbers used to form a product, wherein the rubbers have different colors and different hardness; selecting one type of rubber from the rubbers used to form the product, putting the rubber selected into a first mold, and performing mold forming to form a first molded product; putting part of the first molded product into a second mold, closing the second mold, and then injecting a second rubber selected from the rubbers used to form the product for mold forming to form a second molded product; putting part of the second molded product into a Nth mold, closing the Nth mold, and then injecting a Nth rubber selected from the rubbers used to form the product for mold forming, and then cooling to obtain the product completely.

A pet toy includes a core body and a coating layer. The core body is made of a first material. The core body includes a first core body member and a second core body member that are mated together to have a space therebetween. The coating layer covers the core body. The coating layer is made of a second material that is different from the first material.
