본 발명은 구조적인 예비성형체들을 제조하기 위한 방법 및 장치를 제공하는 유도된 섬유의 에너지 인가공정에 관한 것이다. 섬유의 보강 재료는 짧은 길이로 절단되어 관통된 몰드부로 투입된다. 관통된 몰드부위에 투입 및 또는 침전동안에 섬유들은 전자기선에 의해 경화가능한 결합제로 스프레이된다. 결합제 함유 섬유들은 공기흐름에 의해 관통된 몰드부위에 유지되고, 관통된 몰드부는 공기흐름을 제공하는 프리넘 안에 회전가능하게 설치된다. 관통된 몰드부의 회전 및 섬유 및 결합제 투입장치들의 방사작용은 관통된 몰드부의 균일하고 완전한 도포에 효과적이다. 절단된 섬유들의 매트가 관통된 몰드부에 도포된 후에, 견고한 3차원 예비성형체의 형태를 복제하기 위하여 제2몰드부는 몰드와 근접하게 되어 섬유들을 압축한다. 전자기선 투과성 재료로 제작된 몰드에 있어서, 압축된 섬유들은 결합제를 경화시키고 견고한 3차원요소로 매트의 섬유들을 결합시키기 위해 전자기선에 노출된다. 보조부재나 부재들과 같은 서브조립체는 예비성형체 및 또는 서브조립체의 선택된 영역에 전자기 에너지 경화성 결합제를 도포하고, 보재부재를 소정의 방위로 위치시키며 선택된 결합제 코팅된 영역에 예비성형체와 친밀하게 접촉되도록 위치시킴으로써 부착될 수 있고, 상기 선택된 영역에서 결합제는 전자기 에너지를 가함으로써 경화된다. 전자기 에너지는 예를들어, 마이크로파 복사선 및 또는 자외선일 수 있다. The present invention is directed to an energy application process of induced fibers providing a method and apparatus for producing structural preforms. The reinforcing material of the fiber is cut into short lengths and fed into the penetrated mold part. During injection and / or precipitation into the perforated mold site, the fibers are sprayed with a curable binder by electromagnetic radiation. Binder-containing fibers are held on the penetrated mold portion by airflow, and the penetrated mold portion is rotatably installed in a plenum that provides airflow. The rotation of the penetrated mold portion and the spinning action of the fibers and binder injectors are effective for uniform and complete application of the penetrated mold portion. After the mat of cut fibers is applied to the penetrated mold portion, the second mold portion is brought into close proximity to the mold to compress the fibers in order to replicate the shape of the rigid three-dimensional preform. In a mold made of electromagnetically transparent material, the compressed fibers are exposed to electromagnetic radiation to cure the binder and bond the fibers of the mat into rigid three-dimensional elements. A subassembly, such as an auxiliary member or members, applies an electromagnetic energy curable ...

Method and device for producing preforms

본 발명은 후속 스트레치 블로우 몰딩에 대해 최적화된 기저 기하학적 형상을 갖는 예비성형체를 제조하기 위한 방법 및 장치에 관한 것이다. 사출 몰드 내에서 제조된 예비성형체는 냉각식 제거 슬리브 내에서 제거되고 집중적 접촉 냉각에 의해 샤프트 내에서 냉각되며 냉각 슬리브의 특정 윤곽으로 인해 돔형 예비성형체 단부와의 냉각 접촉이 이루어지지 않는다. 그 결과, 이 돔형 단부의 재-가열을 고려하여, 이는 벽 두께에 영향을 미치고 블로우-몰딩 공정에 대해 더욱 선호되는 신규한 기하학적 형상으로 기계적으로 변형될 수 있다. 후속 블로우-몰딩 공정에서, 이러한 변형된 예비성형체는 주요하게는 병 내에서 더 양호하게 분포된 중합체 재료가 상당한 재료 절감을 야기하고 고 품질의 병 기저를 제공하는 이점을 갖는다. The present invention is directed to a method and apparatus for producing preforms having an underlying geometric shape optimized for subsequent stretch blow molding. The preforms produced in the injection mold are removed in a cooled removal sleeve and cooled in the shaft by intensive contact cooling and due to the particular contour of the cooling sleeve there is no cooling contact with the domed preform end. As a result, taking into account the re-heating of this domed end, it can be mechanically deformed into a novel geometry that affects the wall thickness and is more preferred for blow-molding processes. In the subsequent blow-molding process, this modified preform has the advantage that the polymer material, which is better distributed in the bottle, mainly results in significant material savings and provides a high quality bottle base.
