Title (EN) METHOD FOR PRODUCING HOT-STAMPED ALUMINUM CASE AND HOT-STAMPED ALUMINUM CASE PRODUCED BY METHOD
(FR) PROCÉDÉ DE PRODUCTION D'UN BOÎTIER EN ALUMINIUM ESTAMPÉ À CHAUD ET BOÎTIER EN ALUMINIUM ESTAMPÉ À CHAUD AINSI PRODUIT
(KO) 핫스탬핑 알루미늄 케이스의 제조방법 및 그 방법에 의해 제조된 핫스탬핑 알루미늄 케이스
Abstract: front page image
(EN) A method for producing a hot-stamped aluminum case and a hot-stamped aluminum case produced by the method according to the present invention increases the tensile strength and elongation of an aluminum alloy, optimizes processes for a stable dimension, a post-processing treatment and an increased yield thereof, and prevents defects, such as pinholes, shrinkage, cracking and blow holes, during process performance, thereby enhancing the physical properties. Further, process performance is easy, thereby reducing the cost and time for processing an aluminum alloy material, while maintaining excellent physical properties of the alloy such as strength and hardness.
(FR) L'invention concerne un procédé de production d'un boîtier en aluminium estampé à chaud. Un boîtier en aluminium estampé à chaud produit par le procédé de la présente invention augmente la résistance à la traction et l'allongement d'un alliage d'aluminium, optimise les processus pour obtenir des dimensions stables, réaliser un post-traitement et obtenir un rendement accru de ce dernier, et empêche des défauts tels que des trous d'épingle, des retraits, des fissures et des trous de soufflage pendant la mise en œuvre du procédé, ce qui améliore les propriétés physiques. En outre, le procédé est facile à mettre en œuvre, ce qui permet de réduire le coût et le temps de traitement d'un matériau en alliage d'aluminium, tout en conservant les excellentes propriétés physiques de l'alliage telles que sa résistance et sa dureté.
(KO) 본 발명의 핫스탬핑 알루미늄 케이스 제조방법 및 그 방법에 의해 제조된 알루미늄 케이스는 알루미늄 합금의 인장강도 및 신율을 증대시키며, 이에 대한 안정적인 치수, 후가공 처리 및 수율 증대를 위한 공정을 최적화하고, 공정 수행 중 핀홀, 수축, 크랙, 기공 등의 결함이 발생하지 않도록 하여 물성을 증대시킬 수 있다. 또한, 공정 수행이 용이하여 알루미늄 합금 소재의 가공비용 및 시간을 절감할 수 있고 그와 동시에 합금의 강도, 경도 등의 물성은 우수하게 유지할 수 있다.
