Title:
伝動装置のための保護ベローズを備えたケーシングを製造する方法及びこの方法によって得られるケーシング
Document Type and Number:
Japanese Patent JP2006510515
Kind Code:
A
Abstract:
The procedure consists of injecting thermoplastic or thermoplastic elastomer material into mold cavity formed between hollow mold and inner core(s) having matching spiral threaded surfaces. The molded component (1), having preferable hardness of 60 Shore D, is removed from mold by unscrewing core(s) and mold relative to one another. The procedure consists of injecting thermoplastic or thermoplastic elastomer material into mold cavity formed between hollow mold and inner core(s) having matching spiral threaded surfaces. The molded component (1), having preferable hardness of 60 Shore D, is removed from mold by unscrewing core(s) and mold relative to one another. The mold and core have a truncated conical shape, with the greatest section of the core having a diameter smaller than or equal to fastening portion (3A) of bellows, which is in turn of greater diameter than largest pleated section. In addition the fastening portions (3A, 3B) of the bellows can be made from at least two bi-injected materials, one of which is able to reflect thermal radiation.
