用于制造由复合材料构成的摆锤的方法
摘要：
本发明涉及一种用于制造用于手表的自动上条机构的摆锤(1a；1b)的方法，该摆锤具有由第一复合材料制成的中央部(3a；3b；3c)和由填充有重金属粒子的第二复合材料制成的重质区段(5a；5b；5c)，所述方法包括以下步骤：‑通过向模具中注入第一复合材料来形成具有侧向肋和凹陷部的中央部(3a；3b；3c)；‑通过向包含中央部的模具中注入第二复合材料来将重质区段(5a；5b；5c)包覆成型在中央部上，以便第二复合材料充填凹陷部以及侧向肋下方的间隙，从而侧向肋被包埋在第二复合材料中并且中央部和重质区段被互锁。
摘要（英）：

A method for making an oscillating weight for an automatic winding mechanism of a self-winding watch including a central part made from a first composite material and a heavy sector made from a second composite material charged with heavy metal particles, the method including: forming the central part with a lateral rib and a rebate by injecting the first composite material into a mold; overmolding the heavy sector onto the central part by injecting the second composite material into a mold containing the central part, so that the second composite material fills the rebate and a gap underneath the lateral rib, so that the lateral rib is embedded in the second composite material and the central part and the heavy sector are interlocked.
