摘要:
A process for making a multilayered article, the process comprising the steps of: (A) Providing a mold comprising: (1) A mold housing comprising (a) at least one injection port, and (b) defining a mold cavity within which are positioned two deformable, pre-molded polymeric sheets; and (2) A removable, hollow core equipped with at least one vent, the removable, hollow core positioned between and space apart from the two polymeric sheets; (B) injecting under high pressure a viscous, crosslinkable, thermoplastic polymer into the mold cavity between the two polymeric sheets and around the removable core, (C) Drawing a vacuum on the mold cavity through both the vent in the mold housing and the vent in the removable, hollow core before, during and/or after the polymer has been injected into the mold; (D) Forming a less than fully cured multilayered article in the mold cavity; and (E) Removing the less than fully cured multilayer article from the mold cavity.

It is illustrated a process for the production of tyres for vehicle wheels which comprises the steps of: a) building the tyres (8) on respective toroidal supports assembling a plurality of structural components of each of them according to a predetermined sequence at respective workstations (6); b) transferring the tyres (8) built on the toroidal supports to a vulcanisation plant (3); c) molding and partially vulcanising the tyres (8) on the toroidal supports in respective vulcanisation molds (4) associated with said vulcanisation plant (3); d) removing the partially vulcanised tyres (8) with the respective toroidal supports from the respective vulcanisation mods (4); e) completing the vulcanisation of the tyres (8) outside said vulcanisation molds (4) by means of the heat given to the tyres (8) by said toroidal supports.
摘要:
The present invention relates to a method for quickly shaking out plastics molded articles of manufacture, which comprises the steps of mixing addition curing plastic materials with radically radiating curing plastics materials, pouring the obtained mixture into a mold, radiating by a light radiation compatible to the radically curing plastics materials, in order to provide a self-supporting molded or cast article of manufacture, and withdrawing this article of manufacture from the mold thereby allowing the addition curing plastics materials to fully cure or polymerize.
摘要:
A method for producing a bladder (B) includes shaping a mass of crude rubber containing an oil component into a specified bladder shape by a mould, vulcanising the shaped bladder in the mould, removing the vulcanised bladder from the mould, placing the vulcanised bladder in an environment (18) having a high temperature to keep the vulcanised bladder (B) in the high temperature for a specified time to remove the oil component from the vulcanised bladder, and coating an outer surface of the oil component-removed bladder with a separating agent layer.
摘要:
A process for producing metal clad laminates comprising the steps, all in continuous manner, of: (a) joining a plurality of substrate sheets impregnated with a liquid resin capable of curing without generating volatile by-products to form a wet laminate; (b) applying a metal foil onto at least one side of the wet laminate; (c) preheating the wet laminate immediately before or after step (b) before the liquid resin is immobilized; (d) compressing and heating the wet laminate by a double belt press in its pressing zone to cure the laminate into a rigid state; (e) subjecting the lamiate to curing after releasing it from compression to complete the curing reaction and to relax internal stress therein; and (f) cutting the cured laminate to a predetermined length.
摘要:
A seal and a method of manufacturing a seal for a blowout preventer. The seal includes a rigid material insert disposed within an elastomeric body, with at least a portion of the rigid material insert selectively de-bonded from the elastomeric body.
摘要:
A post cure inflator of the present invention is an apparatus for inflating and cooling a vulcanized tire T by sealing high pressure air into the vulcanized tire, and includes an annular rim for gripping the vulcanized tire at a bead portion, a connecting member fixed at one end portion thereof to the rim, a rim supporting member provided in a body frame, and a clamping device provided in the rim supporting member to clamp the connecting member to the rim supporting member unclampably. This construction permits a post cure inflator in which replacement of the rim is easy and an existing rim can be used.
