摘要： A vehicle has a movable member movably disposed in an opening to close or open the opening. The seal is mounted to one of the movable member and an inner edge surrounding the opening conforming to each other. The seal has a seal portion subject to elastic deformation when being pressed against the movable member or the inner edge. The seal portion is made of a vulcanizable rubber. A base portion is made of a thermoplastic elastomer. The seal portion and the base portion are integrated by coextrusion. The rubber of the seal portion is vulcanized when passing through a vulcanizer.

摘要： A method for producing a rubber based weather strip characterized as containing a metal core and as having a decorating treatment and/or a lubricating treatment applied to a surface of the rubber base which is made of EPDM. The decorating and/or lubricating treatment is effected by adhesively bonding a decorative and/or lubricating member to the surface of the rubber base. The method avoids the need for the conventional buffing step. This results in higher productivity for the production line which lowers costs and improves the work environment due to the absence of buffing dust. This method includes the steps of applying a corona discharge treatment to the surface of the rubber base of EPDM which has previously been subjected to a vulcanizing treatment, with the metal core being grounded, so that polar functional groups are formed in a molecular chain of the EPDM. The decorating treatment and/or the lubricating treatment is then applied to the surface of the rubber base in which the polar functional groups have been formed.
摘要翻译：一种用于生产橡胶基耐候条的方法，其特征在于包含金属芯，并且具有施加在由EPDM制成的橡胶基底的表面上的装饰处理和/或润滑处理。装饰和/或润滑处理通过将装饰和/或润滑构件粘合到橡胶基底的表面来实现。该方法避免了常规抛光步骤的需要。这导致生产线的生产率提高，这降低了成本，并且由于没有抛光粉尘而改善了工作环境。该方法包括以下步骤：将电晕放电处理施加到预先进行硫化处理的EPDM的橡胶基材的表面上，使金属芯接地，从而在分子链中形成极性官能团 EPDM。然后将装饰处理和/或润滑处理施加到已经形成极性官能团的橡胶基材的表面。

摘要： A mold for hollow injection molding has an inlet for admitting a fluid into the molten resin when injected to form an interior hollow in the molded product. The inlet is opened and closed by retraction and advancement of a movable pin having at least a portion to fill the inlet and close it. When the inlet is closed, while the resin is being injected, the pin has a portion which projects out of the inlet into the space where the resin is injected. When the inlet is opened, the retraction of the pin leaves a short passageway in the injected resin leading from the fluid inlet for flow thereinto of the hollow-forming fluid. Preferably, the pin is stepped with an inlet-closing large rear portion and a smaller projecting forward portion which is located in and has an annular clearance with the inlet when it is open. The pin may be detachably connected to a movable plunger, operated by fluid or spring pressure, to enable replacement by pins of different lengths, sizes, etc.
摘要翻译：用于中空注射成型的模具具有用于在注射时将流体进入熔融树脂的入口，以在模制产品中形成内部空心。通过缩回和推进具有至少一部分以填充入口并将其关闭的可动销的入口打开和关闭。当入口关闭时，在注射树脂时，销具有从入口突出到注入树脂的空间的部分。当入口打开时，销的缩回在从流体入口引出的注入的树脂中留下短的通道，以流入中空形成流体。优选地，销具有入口关闭大后部和较小的向前突出的台阶，当其打开时，该向前部位于入口处并具有环形间隙。销可以可拆卸地连接到由流体或弹簧压力操作的可移动柱塞，以使得能够通过不同长度，尺寸等的销替换。

摘要： Molding a hollow shaped body which has a skin made of a synthetic resin and a hollow portion therein by a mold block provided with a mold cavity in the shape of the hollow shaped body, a tub into which an excess amount of the synthetic resin can flow and a small flow path communicating between the mold cavity and the tub. The process includes forming the skin of the hollow shaped body by injecting a molten synthetic resin into the mold cavity to fill up the cavity. Thereafter, a gas is introduced into the injected synthetic resin to thereby form the hollow portion. The gas injection forces a part of the synthetic resin out of the mold cavity and into the tub through the small flow path.
摘要翻译：通过具有中空成型体形状的模腔的模块将由合成树脂制成的皮肤和中空部分成型的中空成形体成型为能够流过多余合成树脂的桶以及在模腔和桶之间连通的小流路。该方法包括通过将熔融的合成树脂注射到模腔中以填充空腔来形成中空成形体的表皮。此后，将气体引入注入的合成树脂中，从而形成中空部分。气体注入迫使合成树脂的一部分通过小流动通道进入模腔并进入桶中。
