(EN) FLOAT MANUFACTURING METHOD UTILIZING CORE
(FR) PROCÉDÉ DE FABRICATION DE FLOTTEUR METTANT EN ŒUVRE UN NOYAU
(KO) 코어를 구비하는 부구제작방법
Abstract
(EN)
The present invention relates to a float manufacturing method utilizing a core. The float manufacturing method using a core (40) is for manufacturing the float by injecting synthetic resin particles into a die and applying heat to melt same, wherein the die is divided into the three parts of a fixing die (10), an intermediate die (20), and a moving die (30). The present invention has the remarkable effect of enabling a lightweight, high-strength, and high-quality float absent of defects to be manufactured easily and rapidly by injection-molding and foaming the float using an outer core and an inner core.
(FR)
La présente invention concerne un procédé de fabrication de flotteur mettant en œuvre un noyau. Le procédé de fabrication de flotteur mettant en œuvre un noyau (40) est destiné à fabriquer le flotteur en injectant des particules de résine synthétique dans une matrice et en appliquant de la chaleur pour faire fondre celles-ci, la matrice étant divisée en trois parties, à savoir une matrice fixe (10), une matrice intermédiaire (20) et une matrice mobile (30). La présente invention a pour effet notable de permettre une fabrication aisée et rapide d'un flotteur léger, de haute résistance et de haute qualité dépourvu de défauts, par moulage par injection et moussage du flotteur au moyen d'un noyau externe et d'un noyau interne.
