A method, a dosing device and a system for manufacturing of a lipstick mine out of at least two pasty substances are described. The method comprises inserting of a first end portion of a dosing device into a form whereby the first end portion of the dosing device comprises at least one outlet nozzle, filling of the first end portion of the dosing device with a first pasty substance, increasing of the gas pressure in the first end portion of the dosing device whereby the first pasty substance through the pressure is pressed out of the at least one outlet nozzle, removing the first end portion of the dosing device out of the form and filling up the form with a second pasty substance.

A play ball has a rubber shell filled with resilient foam having an entire outer peripheral surface thereof intimately attached by heat fusion and adhesive to an entire interior surface of the shell. Such attachment enables the foam to provide additional resiliency by foam tension, as well as by foam compression, thereby significantly extending the effective bounce life of the ball. A seamed dog chew toy has essentially similar construction such that the increased retention force provided by the intimate attachment of the foam to the shell resists the chewing force of the dog popping a seam improving durability.

A method for manufacturing a shoe sole with multi-material spikes includes: providing a spike-forming mold which includes an upper mold and a lower mold, wherein the lower mold includes a first filling hole which is in communication with the first spike cavity, different materials are placed in the first spike cavity to form the multi-material spike; providing a first mold which includes a second spike cavity; providing a second mold which includes a second filling hole; assembling the first and second molds, together to form a sole cavity, wherein the multi-material spike is placed into the sole cavity, a sole material is filled into the sole cavity through the second filling hole, and then the multi-material spike and the sole material are adhered to each other by hot melting; and opening the first and second molds, and obtaining a shoe sole with the multi-material spike.

A composite product is made by forming an object body comprising a mixture of rubber crumb and binder having a first temperature-dependent cure rate. A surface layer of a vulcanizable rubber compound having a second temperature-dependent cure rate is brought into contact with the object body, and the surface layer and the object body are simultaneously cured at different temperatures so as to match said first and second cure rates such that the surface layer adheres to the object body.
