Abstract (en)
The weight has an oscillating sector (1), and a hub provided with a cylindrical bore (4), where the weight is formed by molding a plastic material charged with heavy metal particles and fibers. The fibers are formed between 2 and 3.5 percentages of total weight of the charged material, where density of the charged material is greater than 8. The heavy metal is tungsten. The plastic material is polyamide-12. The fibers are glass fibers and carbon fibers. The plastic material, heavy metal and the fibers form a mixture that is made by mixing Grilamid-TR(RTM: high-performance polyamides) and Gravi-Tech(RTM: polymer-metal composites) fibers.
Abstract (fr)
Procédé de fabrication d'une masse oscillante pour remontoir automatique de montre par moulage d'une matière plastique chargée de particules d'un métal lourd. De plus, la matière plastique est encore chargée de fibres, lesdites fibres constituant entre 1,5% et 7% du poids total de la matière plastique chargée, et la densité de la matière plastique chargée est supérieure à 8.
