用于制造带有削弱部分注塑件的系统和方法
摘要：
本公开提供一种在注塑系统中制造带有削弱部分的注塑件的方法，所述注塑系统包括由固定模具部分和可移动模具部分限定的型腔。所述方法包括：将液态原料注入所述型腔以形成所述注塑件；将削弱插入件从所述注塑件的第一表面移入所述注塑件中；使用受控制的压力将气体注入所述注塑件的所述第一表面，其中，当所述注塑件为液态时，执行将所述削弱插入件移入所述注塑件并注入气体。
摘要（英）：

The invention provides a method for manufacturing an injection-molded part provided with a weakened portion in an injection molding system. The injection molding system comprises a molding cavity defined by a fixed mould portion and a movable mould portion. The method comprises the steps that liquid raw materials are injected into the molding cavity to form the injection-molded part; a weakened insertion piece is moved into the injection-molded part from a first surface of the injection-molded part; and gas is injected into the first surface of the injection-molded part by means of controlled pressure, wherein when the injection-molded part is in a liquid state, the weakened insertion piece is moved into the injection-molded part, and the gas is injected.
