Zusammenfassung:	The present invention provides a hot stamping component manufacturing method comprising the steps of: forming a blank by cutting a plated steel sheet having a plating layer formed on at least one surface of a base metal; and heating the blank in a heating furnace including a plurality of sections with different temperature ranges, wherein the step of heating the blank comprises: a multistage heating step of heating the blank step by step; and a soaking step of heating the multistage-heated blank at a temperature of Ac3 to 910°C, and the temperature (an) of the soaking step and the total heating time (bn) of the step of heating the blank satisfy the relation. 62 ≤ 91.81 + K - 0.022 x an - 0.23 x bn (In the relation, K is a material correction factor.) La présente invention concerne un procédé de fabrication d'élément d'estampage à chaud comprenant les étapes consistant à : former une ébauche par la découpe d'une tôle d'acier plaquée ayant une couche de placage formée sur au moins une surface d'un métal de base ; et chauffer l'ébauche dans un four de chauffage comprenant une pluralité de sections ayant différentes plages de température, l'étape consistant à chauffer l'ébauche comprenant : une étape de chauffage par étapes multiples consistant à chauffer l'ébauche pas à pas ; et une étape de trempage consistant à chauffer l'ébauche chauffée par étapes multiples à une température de Ac3 à 910 °C, et la température (an) de l'étape de trempage et le temps de chauffage total (bn) de l'étape de chauffage de l'ébauche satisfont la relation. 62 ≤ 91,81 + K - 0,022 x an - 0,23 x bn (Dans la relation, K est un facteur de correction de matériau.) 본 발명은 모재의 적어도 일면 상에 도금층이 형성된 도금강판을 재단하여 블랭크를 형성하는 단계; 및 서로 다른 온도 범위를 갖는 복수의 구간을 구비한 가열로 내에서 상기 블랭크를 가열하는 단계;를 포함하고, 상기 블랭크를 가열하는 단계는, 상기 블랭크를 단계적으로 가열하는 다단 가열 단계; 및 상기 다단 가열된 블랭크를 Ac3 내지 910℃의 온도로 가열하는 균열 가열 단계;를 포함하며, 상기 균열 가열 단계의 온도(an) 및 상기 블랭크를 가열하는 단계의 총 가열 시간(bn)은 하기 관계식을 만족하는, 핫 스탬핑 부품의 제조 방법이 제공된다. 62 ≤ 91.81 + K - 0.022 x an - 0.23 x bn (상기 관계식에서 K는 소재 보정 계수이다.)
