개요 다이캐스팅은 가장 경제적이고 빠른 성형 공정 중 하나입니다. 이 생산 공정의 장점은 단 하나의 금형을 사용하여 수십만 개의 주물을 비교적 빠르게 생산할 수 있다는 것입니다. 생산되는 모든 구성 요소는 균일 한 품질을 가지며 상대적으로 낮은 단가를 포함합니다. 다이캐스팅은 액체 용융물을 고압 (150~1200bar)과 높은 충전 속도 (최대 540km/h)로 금형에 압착하는 자동 주조 공정입니다. 일반적으로 융점이 낮은 합금을 사용합니다. 이 주조
![Die casting is mostly used because many parts need to be manufactured in a short amount of time (hundreds to thousands per day) with high accuracy. Parts like valve covers, wheels, transmission housings, engine block, wheel spacer, carburetor, impellers and fan clutch, alternator housing, airbag gas generator housing, etc. are all modes through the aluminum die casting method. Automobile parts require uniformity and high surface finish which can be accomplished by using casting methods that work in a controlled environment- pressure dies casting. Die casting was originally developed specifically for automotive applications [28]. The idea is to produce parts that are light, easy to handle, and cheap. Thus, die casting is widely applied to zinc and aluminum which are lighter than cast iron. Figure 2 shows the aluminum die-cast parts of a car. PEGASUS has been supplying quality aluminum die-cast auto parts to the automobile industry with our stable production system since we started this business in 2007 [27]. At present, we are supplying 60 kinds of die-cast products with our unique mold design and casting technology in addition to the processing technology we have been cultivating in the industrial sewing machine industry [29]. Aluminum or Al-Si alloys are used for Die casting. During this process, molten metal is injected at high pressure into a die (made of metal) which is a permanent mold comprising of two parts of the desired shape attached [30].](https://castman.co.kr/wp-content/uploads/Figure-2.-Application-of-die-casting-to-produce-auto-parts-27-570x342.png)
