Described herein is a manual process for injection molding of coated components, more particularly coated soles of plastic, where first of all the molding tool is lined with a release agent composition and, after flashing of this release agent composition, a composition for forming the component is injected. After crosslinking of these two compositions, the produced coated component is removed from the molding tool and subjected optionally to an aftertreatment.

A release agent for being coated onto a tire bladder made of a zinc-oxide-incorporated butyl rubber during pneumatic-tire molding, the release agent containing (A) organopolysiloxane, which contains a carboxy group indicated by the general formula (1) below ##STR00001##
(in the formula, R.sup.1 is a substituted or unsubstituted C1-C30 monovalent hydrocarbon group excluding R.sup.2, R.sup.2 is a carboxy-group-substituted C1-C30 monovalent organic group, R.sup.3 is R.sup.1 or R.sup.2, and n is an integer of 3 to 2000.). This release agent produces a longer service life of a tire bladder and leads to reduced tire production cost because the amount of silicone that migrates to the tire side is low when the tire is released, and repeated mold-release performance is enhanced.

A method of lubricating an expandable rubber bladder is described for use during a vulcanization of a green tire within a metal press. The method can include applying compositions in the form of emulsions of silicone oils to the inner surface of the green tires and/or to the outer surface of the vulcanization bladders to facilitate the molding-demolding thereof during the manufacture of the tires.

The present invention provides a manufacturing device and a manufacturing method for molds. The manufacturing device includes a molding assembly including a mold table and a male mold. The mold table has an upper surface defining a depression thereon, and the male mold is configured to be disposed on a bottom surface of the depression. A height of the male mold is smaller than a depth of the depression. This manufacturing device can utilize a transfer molding method to manufacture molds in batches with higher mold production efficiency.

Embodiments of the present invention include non-pneumatic tires (100) having an electrically conductive path, and methods for forming the same. It is appreciated electrical charges may be generated during land vehicle operation and land vehicles are often grounded by providing an electrically conductive path between the vehicle and the ground. In embodiments of the present invention, a non-pneumatic tire (100) and a method for forming a non-pneumatic tire are described for providing an electrically conductive path between the vehicle and the ground at the non-pneumatic tire. The method for forming the non-pneumatic tire comprises the step of applying a mold release (290) to one or more molding surfaces (280) of the spoke mold wherein the mold release (290) includes an electrically conductive additive.
