    摘要： A method for producing a damper for an air line of an internal combustion engine includes the following steps: providing a temperature-controlled inner part having passages; producing a tubular preform of an outer jacket from a thermoplastic melt; and attaching the temperature-controlled inner part to a blowing mandrel of a blow mold which is open. The blowing mandrel has outlet openings and the passages are positioned over the outlet openings. The method further includes bringing the temperature-controlled preform over the inner part and closing the blow mold such that the preform is blown against the walls of the blow mold whereby an outer jacket is obtained. Simultaneously, local connections between the inner part and the outer jacket are obtained by pressing the preform and the inner part against each other in some regions. Finally, the blow mold is opened and the damper is removed.

    摘要翻译： 一种用于制造内燃机的空气管路的阻尼器的方法，包括以下步骤：提供具有通道的温度控制的内部部件; 从热塑性熔体制造外护套的管状预制件; 并将温度控制的内部部件附接到打开的吹塑模具的吹塑心轴。 吹风心轴具有出口开口，通道位于出口开口的上方。 该方法还包括使温度控制的预成型件在内部部分上并且关闭吹塑模具，使得预成型件被吹送到吹塑模具的壁上，由此获得外套。 同时，通过在一些区域中将预制件和内部部件彼此挤压来获得内部和外部套管之间的局部连接。 最后，打开吹塑模具，并拆下阻尼器。
