ABSTRACT

논문의 일부로 튜터 선택 가능성과 해결해야 할 주제가 설정되는 매개변수를 염두에 두고 개발 주제 ‘Flow- 3D ®에 의한 저압 충전 시스템 최적화’가 선택되었습니다. 이를 위해서는 달성해야 할 목표와 이를 달성하기 위한 방법을 정의하는 것이 필요했습니다.

충전 시스템을 시뮬레이션하고 검증할 수 있는 광범위한 소프트웨어에도 불구하고 Flow-3D®는 시장에서 최고의 도구 중 하나로 표시되어 전체 충전 프로세스 및 행동 표현과 관련하여 탁월한 정확도로 시뮬레이션하는 능력을 입증했습니다.

이를 위해 관련 프로세스를 더 잘 이해하고 충진 시스템 시뮬레이션을 위한 탐색적 기반 역할을 하기 위해 이 도구를 탐색하는 것이 중요합니다. 지연 및 재료 낭비에 반영되는 실제적인 측면에서 충전 장치의 치수를 완벽하게 만드는 비용 및 시간 낭비. 이러한 방식으로 저압 주조 공정에서 충진 시스템을 설계하고 물리적 모델을 탐색하여 특성화하는 방법론을 검증하기 위한 것입니다.

이를 위해 다음 주요 단계를 고려하십시오.

시뮬레이션 소프트웨어 Flow 3D® 탐색;
충전 시스템 모델링;
모델의 매개변수를 탐색하여 모델링된 시스템의 시뮬레이션, 검증 및 최적화.

따라서 연구 중인 압력 곡선과 주조 분석에서 가장 관련성이 높은 정보의 최종 마이닝을 검증하기 위한 것입니다.

사용된 압력 곡선은 수집된 문헌과 이전에 수행된 실제 작업을 통해 얻었습니다. 결과를 통해 3단계 압력 곡선이 층류 충진 체계의 의도된 목적과 관련 속도가 0.5 𝑚/𝑠를 초과하지 않는다는 결론을 내릴 수 있었습니다.

충전 수준이 2인 압력 곡선은 0.5 𝑚/𝑠 이상의 속도로 영역을 채우는 더 난류 시스템을 갖습니다. 열전달 매개변수는 이전에 얻은 값이 주물에 대한 소산 거동을 확증하지 않았기 때문에 연구되었습니다.

이러한 방식으로 주조 공정에 더 부합하는 새로운 가치를 얻었습니다. 달성된 결과는 유사한 것으로 나타난 NovaFlow & Solid®에 의해 생성된 결과와 비교되어 시뮬레이션에서 설정된 매개변수를 검증했습니다. Flow 3D®는 주조 부품 시뮬레이션을 위한 강력한 도구로 입증되었습니다.

As part of the dissertation and bearing in mind the parameters in which the possibility of a choice of tutor and the subject to be addressed is established, the subject for development ’Optimization of filling systems for low pressure by Flow 3D ®’ was chosen. For this it was necessary to define the objectives to achieve and the methods to attain them. Despite the wide range of software able to simulate and validate filling systems, Flow 3D® has been shown as one of the best tools in the market, demonstrating its ability to simulate with distinctive accuracy with respect to the entire process of filling and the behavioral representation of the fluid obtained. To this end, it is important to explore this tool for a better understanding of the processes involved and to serve as an exploratory basis for the simulation of filling systems, simulation being one of the great strengths of the current industry due to the need to reduce costs and time waste, in practical terms, that lead to the perfecting of the dimensioning of filling devices, which are reflected in delays and wasted material. In this way it is intended to validate the methodology to design a filling system in lowpressure casting process, exploring their physical models and thus allowing for its characterization. For this, consider the following main phases: The exploration of the simulation software Flow 3D®; modeling of filling systems; simulation, validation and optimization of systems modeled by exploring the parameters of the models. Therefore, it is intended to validate the pressure curves under study and the eventual mining of the most relevant information in a casting analysis. The pressure curves that were used were obtained through the gathered literature and the practical work previously performed. Through the results it was possible to conclude that the pressure curve with 3 levels meets the intended purpose of a laminar filling regime and associated speeds never exceeding 0.5 𝑚/𝑠. The pressure curve with 2 filling levels has a more turbulent system, having filling areas with velocities above 0.5 𝑚/𝑠. The heat transfer parameter was studied due to the values previously obtained didn’t corroborate the behavior of dissipation regarding to the casting. In this way, new values, more in tune with the casting process, were obtained. The achieved results were compared with those generated by NovaFlow & Solid®, which were shown to be similar, validating the parameters established in the simulations. Flow 3D® was proven a powerful tool for the simulation of casting parts.

정수압 초기화

사용자가 사전 정의된 금속 영역에서 정수압을 초기화해야 하는 경우가 종종 있습니다. 크고 복잡한 시뮬레이션에서는 정수압 솔버의 수렴 속도가 느려지는 경우가 있습니다. FLOW-3D CAST 2023R2는 정수압 솔버의 성능을 크게 향상시켜 전처리 단계에서 최대 6배 빠르게 수렴할 수 있도록 해줍니다.

열 다이 사이클링 - 샷 슬리브 — 새로운 Thermal Die Cycling 모델로 예측된 샷 슬리브의 온도 분포

FLOW-3D CAST 2023R2 의 재설계된 열 다이 사이클링(TDC) 모델은 고압 다이 캐스팅 및 기타 영구 금형 주조 공정의 프로세스 시트와 더 잘 일치하는 더 간단하고 직관적인 설정 프로세스를 제공합니다.

이제 TDC 시퀀스는 충전 단계의 시작 부분 에서 시작되어 하위 프로세스 전반에 걸쳐 시간에 따른 냉각/가열 라인 정의에 대한 더 높은 정확성과 정렬을 제공합니다. 향상된 스프레이 냉각 모델을 통해 사용자는 부품별로 처리 일정을 정의할 수 있을 뿐만 아니라 스프레이, 세척 및 코팅 처리에 대한 옵션을 처방할 수 있습니다. 슬라이더 동작도 포함되며 이제 냉각 채널과 가열 요소가 슬라이더와 함께 이동합니다.

이러한 기능은 다양한 단계, 일정, 이동, 처리 및 조립 단계를 보여주는 깔끔하고 직관적인 프로세스 개요를 제공하는 새로운 Thermal Die Cycling 대화 상자를 통해 제어됩니다.

이러한 개발은 개선된 열 솔루션뿐만 아니라 TDC와 관련된 공정의 응고 및 납땜에 대한 더 나은 예측을 촉진합니다.

FLOW-3D CAST 2023R1 의 새로운 기능

FLOW-3D 소프트웨어 제품군의 모든 제품은 2023R1에서 IT 관련 개선 사항을 받았습니다.

FLOW-3D CAST 2023R1은 이제 Windows 11 및 RHEL 8을 지원합니다. Linux 설치 프로그램은 누락된 종속성을 보고하도록 개선되었으며 더 이상 루트 수준 권한이 필요하지 않으므로 설치가 더 쉽고 안전해집니다. 그리고 워크플로를 자동화한 분들을 위해 입력 파일 변환기에 명령줄 인터페이스를 추가하여 스크립트 환경에서도 워크플로가 업데이트된 입력 파일로 작동하는지 확인할 수 있습니다.

FLOW-3D CAST 2023R1 의 고급 기능을 통해 사용자는 다음을 수행할 수 있습니다.

기가캐스팅 제작 시 등 샷 성능 최적화
툴링 마모 해결
고급 탄소강 및 저합금강 주조 시뮬레이션
거시적 분리의 효과를 설명합니다.

플런저 모션 개선

우리는 슬로우 샷 계산기를 개선하여 정확성을 높이고, 공기 혼입을 줄이며, 낮은 충전 수준을 더 잘 처리할 수 있도록 유효성 범위를 확장했습니다. 또한 사용자 인터페이스를 간소화했으며 향상된 슬로우 샷 계산기와 결합하여 인상적인 결과를 제공합니다. 이제 플런저 위치 또는 시간 기반 정의에서 슬로우 샷 계산기의 데이터를 쉽게 사용할 수 있습니다. 새로운 계산기는 또한 슬로우 샷이 끝날 때 혼입되는 공기를 크게 줄이는 세련된 샷 프로필을 제공합니다.

슬로우 샷 계산기 개선 — 2007년 슬로우 샷 계산기와 2022년 버전 비교. 슬로우 샷이 끝나면 새 계산기를 사용하여 동반 공기량이 감소하는 것을 확인하십시오.

확장된 PQ ² 분석

대형 주조는 계산 비용이 많이 들고 기가 주조는 시뮬레이션 소프트웨어를 한계까지 밀어붙일 수 있습니다. 속도 경계 조건이나 금속 입력을 사용하여 샷 슬리브와 플런저를 근사화하는 것은 런타임을 줄이는 유용한 단순화 방법입니다. 그러나 PQ

² 분석 없이는 HPDC 기계가 한계에 가깝게 작동하고 예상대로 작동하지 않아 부품 품질을 위협하는지 알 수 없습니다.

^{우리는 매우 유능한 PQ 2} 분석을 수행 하고 이를 금속 입력 및 속도 경계 조건에 적용하여 이 문제를 해결했습니다. 이는 가장 크고 가장 복잡한 주조에서도 충전 정확도를 유지하면서 처리 시간을 크게 줄이는 것을 의미합니다.

곰팡이 침식 예측

주조 금형과 다이는 기계적 스트레스 요인을 포함한 다양한 이유로 마모됩니다. 기존 전단 하중 측정법은 이 마모를 연구할 때 도움이 되지만 지금까지는 금형에 대한 금속의 충돌을 설명하지 못했고 모래 주조 금형에 포함된 모래의 최종 위치를 예측할 수 없었습니다. 이 문제를 해결하기 위해 우리는 이 마모 메커니즘을 더 잘 이해할 수 있도록 새로운 출력을 추가했습니다. 새로운 출력에는 이러한 유형의 침식이 발생할 가능성이 있는 지역과 모래 함유물의 예상 위치가 표시됩니다.

다이 솔더링 예측

알루미늄 주조에 사용되는 영구 다이는 용융된 알루미늄이 다이의 철과 결합하여 화학적 마모를 겪게 되며, 이는 부품 품질뿐만 아니라 다이의 수명과 유지 관리 요구 사항에 영향을 미치는 땜납을 형성합니다. 이 마모 메커니즘의 중요성으로 인해 우리는 납땜의 위치와 심각도를 모두 예측하는 모델을 구축하게 되었습니다.

다이 솔더링 시뮬레이션 — 시뮬레이션된 솔더(왼쪽)와 관찰된 솔더(오른쪽, 빨간색). 사진은 다이에 관한 것이지만 시뮬레이션에서는 부품을 보여주기 때문에 이미지가 거울처럼 보입니다.

화학 기반 탄소 및 저합금강 응고 모델

우리의 장기 개발 목표 중 하나의 결과는 석출 반응, 응고 및 재용해 경로, 미세 구조 특징 및 결함을 정확하게 설명하는 탄소강 및 저합금강에 대한 강력한 화학 기반 응고 모델 입니다. 이 모델은 또한 중요한 3상 포정반응과 델타 페라이트에서 오스테나이트로의 전이로 인한 대량 수축과 관련된 결함을 설명합니다.

이 모델은 실험과의 탁월한 일치를 보여주며, 예를 들어 과포정 합금이 응고가 끝날 때 페라이트 영역을 개발할 수 있는 이유와 같은 비직관적이고 시간 의존적인 동작에 대한 통찰력을 제공합니다.

거시 분리 예측

대규모 분리는 주조품의 품질과 다운스트림 처리에 중요한 영향을 미칠 수 있으므로 이를 화학 기반 응고 모델에 추가했습니다. 이 모델은 매크로 분리 관련 결함이 발생할 수 있는 위치를 예측하므로 캐스팅 전에 이를 예측하고 완화할 수 있습니다.

FLOW-3D CAST 2022R2 의 새로운 기능

FLOW-3D CAST 2022R2 제품군 출시로 Flow Science는 FLOW-3D CAST 의 워크스테이션과 HPC 버전을 통합하여 단일 노드 CPU 구성에서 다중 노드 병렬 고성능 컴퓨팅 실행. 추가 개발에는 점탄성 흐름을 위한 새로운 로그 형태 텐서 방법, 지속적인 솔버 속도 성능 개선, 고급 냉각 채널 및 팬텀 구성요소 제어, 개선된 동반 공기 기능이 포함됩니다.

통합 솔버

우리는 FLOW-3D 제품을 단일 통합 솔버로 마이그레이션하여 로컬 워크스테이션이나 고성능 컴퓨팅 하드웨어 환경에서 원활하게 실행했습니다.

많은 사용자가 노트북이나 로컬 워크스테이션에서 모델을 실행하지만, 고성능 컴퓨팅 클러스터에서도 더 큰 모델을 실행합니다. 2022R2 릴리스에서는 통합 솔버를 통해 사용자가 HPC 솔루션의 OpenMP/MPI 하이브리드 병렬화와 동일한 이점을 활용하여 워크스테이션과 노트북에서 실행할 수 있습니다.

메쉬 분해의 예 — OpenMP/MPI 하이브리드 병렬화를 위한 메시 분해의 예

솔버 성능 개선

멀티 소켓 워크스테이션

다중 소켓 워크스테이션은 이제 매우 일반적이며 대규모 시뮬레이션을 실행할 수 있습니다. 새로운 통합 솔버를 사용하면 이러한 유형의 하드웨어를 사용하는 사용자는 일반적으로 HPC 클러스터 구성에서만 사용할 수 있었던 OpenMP/MPI 하이브리드 병렬화를 활용하여 모델을 실행할 수 있어 성능이 향상되는 것을 확인할 수 있습니다.

낮은 수준의 루틴으로 향상된 벡터화 및 메모리 액세스

대부분의 테스트 사례에서 10~20% 정도의 성능 향상이 관찰되었으며 일부 사례에서는 20%를 초과하는 런타임 이점이 나타났습니다.

정제된 체적 대류 안정성 한계

시간 단계 안정성 제한은 모델 런타임의 주요 동인이며, 2022R2에서는 새로운 시간 단계 안정성 제한인 3D 대류 안정성 제한을 숫자 위젯에서 사용할 수 있습니다. 실행 중이고 대류가 제한된(cx, cy 또는 cz 제한) 모델의 경우 새 옵션은 일반적인 속도 향상을 30% 정도 보여줍니다.

압력 솔버 프리컨디셔너

경우에 따라 까다로운 흐름 구성의 경우 과도한 압력 솔버 반복으로 인해 실행 시간이 길어질 수 있습니다. 이러한 어려운 경우 2022R2에서는 모델이 너무 많이 반복되면 FLOW-3D가 자동으로 새로운 사전 조절기를 활성화하여 압력 수렴을 돕습니다. 테스트의 런타임은 1.9에서 335까지 더 빨라졌습니다!

점탄성 유체에 대한 로그 형태 텐서 방법

점탄성 유체에 대한 새로운 솔버 옵션을 사용자가 사용할 수 있으며 특히 높은 Weissemberg 수에 효과적입니다.

활성 시뮬레이션 제어 확장

능동 시뮬레이션 제어 기능이 확장되어 연속 주조 및 적층 제조 응용 분야에 일반적으로 사용되는 팬텀 개체는 물론 주조 및 기타 여러 열 관리 응용 분야에 사용되는 냉각 채널에도 사용됩니다.

최적화된 시뮬레이션 설계를 통해 개발 시간을 단축하고 출시 시간을 단축하며 수율을 높일 수 있습니다. FLOW-3D CAST를 사용하면 설계 및 개발 비용을 절감할 수 있습니다.

Investigation of Mould Leakages in a Gravity Casting

This article was contributed by Gabriele Taricco of CM Taricco and Stefano Mascetti of XC Engineering.

Metal leakages in the original gravity casting mould

몰드 설계는 유체 역학과 금속 응고 패턴뿐만 아니라 주형 자체에서 발생할 수 있는 문제와 응력에 대한 반응을 고려해야 하는 매우 복잡한 작업입니다. 이탈리아에 본사를 둔 주형 제작 업체인 CMTaricco 사는 최근에 새로운 주형 중 하나의 하부에서 금속 누출 문제에 직면했습니다. 주형 누출의 원인은 처음에는 분명하지 않았으며 몇 번의 공정 주기 후에만 나타났습니다. 제작 일정에 차질이 생기고 부품 주조 비용이 급격히 증가하기 때문에 문제가 중요한 것은 분명했습니다.

Investigation of an idea

공정 자체는 주입과 오버플로우 설계인 중력 주조 방식이었기 때문에 유체 역학 부분에서는 문제가 발생할 수 없었습니다. GabrieleTaricco (CMTaricco의 소유주)의 가설은 금속 누출이 주형의 열 손실의 설계 불량에서 기인하여 균일하지 않은 분포를 초래한다는 것이었습니다. 변형률과 그에 따라 주형 바닥에서 크고 원하지 않는 변형이 순환하면서 금속이 유출될 수 있는 중요한 영역의 개방까지 주기적으로 시행되었습니다. 이를 확인하고 문제에 대한 신속한 해결책을 찾기 위해 FLOW-3D시뮬레이션을 실행하여 주형이 가열될 때 발생하는 현상을 정확하게 파악했습니다.

A careful setup, to achieve a fast resolution of the issue

문제의 원인은 신속하게 파악할 수 있어야 했기 때문에 최신 Flow-3D기능을 모두 활용하여 정확한 설정이 필요했습니다. 특히, 채택된 meshing기법은 전통적인 설정과 거의 동일한 정확도를 유지하면서 전산 셀의 수를 크게 줄이는데 매우 도움이 되었습니다. 빠른 시뮬레이션으로 주형 세척에 사용된 첫 번째 방법은 주형 내부의 얇은 캐비티를 직교 축과 정렬하기 위해 주형을 수직 축 주위로 회전시키는 것이었습니다.

Rotating the mould around the vertical axis in order to align the inner thin cavity of the mould

두 번째 트릭은 내부 공동 (얇은 벽)에 new conformal mesh기능을 사용하는 한편 전체 도메인에 대해 기존의 더 큰 메쉬 블록을 유지하는 것 이었습니다. The conformal mesh는 open volume과 일치하고, 작은 간극을 갖는 cavity로 제한됩니다.

A global view of the mould with cores and its alignment with the mesh blocks

마지막으로, 외부 공간을 주형에 제한하기 위해(현재 구두 상자 모양이 되고, 20도 회전하며, 모델 축과 정렬상태) 일부’ 도메인제거’ 요소가 사용되었습니다.즉, FLOW-3D의 내부 솔리드 모델을 통해 직접 연결됩니다

Domain removing components (yellow) were used to limit the space externally to the mould.

나머지 설정은 소프트웨어의 권장 기본값 대부분을 이용하여 기존 체계를 따랐습니다. 이러한 기능과 FLOW-3D의 새로운 하위 도메인 분해 기능 덕분에 설계된 9 000 000 셀을 유체 하위 도메인의 경우에만 1 840 000 셀로, 고체 서브 도메인의 경우 2 430 000 셀로 줄이는 것이 가능했습니다.

The analysis

주입 시뮬레이션 후, 양호한 주입 패턴을 보장하기 위해 시뮬레이션의 초점이 열 다이 사이클링 분석으로 리디렉션 되었습니다. 이 경우 설정은 일반 데스크 톱 컴퓨터에서 10개의 생산 사이클을 재현하는 데 1시간이면 간단하고 빠릅니다(i7930 K, 상업적 가치 1500달러). 그 결과 CM의 초기 가설이 확인되었습니다. FlowSight를 사용하여 단일 이미지에서 여러 시점과 횡단면에서 온도 필드를 관찰한 결과 온도가 d라는 것이 분명했습니다. 주형의 침입은 예상되는 변형과 금속 누출을 쉽게 유발할 수 있습니다.

Further analysis with the Fluid-Structure Interaction module

일단 문제가 확인되고 기술 요원이 향상된 금형 설계를 시작하면 CM Taricco는 다이 상의 응력 및 변형에 대한 FEM 해석을 실행하는 최종 확인을 원했습니다. 이 분석을 수행하기 위해 XC Engineering Srl은 CM이 계산을 설정하고 수행하는 것을 도왔습니다. 분석의 결과는 정확히 CM이 생각하고 있는 것을 보여주었습니다. FLOW-3D는 붓기가 거의 걸리지 않은 금형에서 발견 된 실제 변형과 동일한 위치와 크기를 극도의 정확도로 재현 할 수 있었습니다. 이것은 CM에 대한 좋은 소식이었으며, 실제 주조 조건을 기반으로 실제 금형 변형을 예측하기 위해 설계 단계에서 FSI 모듈을 사용하는 추가 권장 사항을 시행했습니다.

Conclusion

해석결과, CM직원은 CFD솔루션의 온도영역에 대한 모든정보를 사용하여 최적화된 새로운 주형을 설계할 수 있었습니다. 새로운 주형은 열 에너지를 보다 효율적인 방법으로 방출할 수 있었으며 주조물은 수 십번의 공정 주기 후에도 금속 누출의 영향을 받지 않았습니다.

Jewelry Casting

FLOW-3D CAST는 엔지니어가 주조 공정 설계 개념을 빠르고 효율적으로 탐구하고 최적화 할 수 있게 합니다. FLOW-3D CAST를 사용하여 위해 귀금속 주조를 포함한 다양한 주물 공정은 보석을 만들기 위해 모델링하고 최적화 할 수 있습니다. 완벽성이 중요한 보석 산업에서 FLOW-3D CAST의 매우 정확한 주입 및 응고 시뮬레이션은 표면 산화물, 공기 침투, 수축 및 기공을 포함한 중요한 보석 주조 결함을 예측합니다. Flow Science의 고도로 숙련 된 기술 엔지니어 팀은 포괄적인 교육은 물론, 전화, 전자 메일 및 금속 주조 산업에 대한 전문가의 지원을 제공합니다.

Single Ring Centrifugal Casting

하나의 백금 링을 FLOW-3D CAST를 사용하여 원심력으로 주조했습니다. 주조 공정에서 중요한 단계인 충진 과정은 주조 엔지니어가 주조 링의 표면 결함, 공기 유입 및 주입 온도를 자세하게 볼 수 있게 시뮬레이션 됩니다.

Gravity Pour

중력 주조는 큰 부품(일반적으로 철, 청동, 황동 또는 알루미늄)을 만드는 데 사용됩니다. 사형 주조 및 영구 금형을 포함한 대부분의 주조 공장 주조 공정은 FLOW-3D CAST를 사용하여 모델링 할 수 있습니다. 주입 프로세스는 고압 다이 캐스팅에 비해 덜하지만 과도한 공기 주입으로 인한 공기 유입으로 인해 품질이 저하될 수 있습니다. 주입하는 동안 잠재적 결함의 위치와 온도의 변화 뿐만 아니라, 용탕 표면의 움직임도 정확하게 예측됩니다. 충진이 완료된 후 용탕의 응고 및 수축을 모델링 할 수도 있습니다.

Accurate Filling Simulations

주조 공정에서 주입 작업은 결함들이 라이저로 이동하는지, 또는 부품에 갇힌 채로 남아 있는지 여부와 같은 주입 패턴 및 관련 결함을 분석하는 작업으로 이루어집니다. 시뮬레이션 분석을 사용하면 설계의 효율성을 검증하고 비용을 절감하면서 생산에 들어가기 전에 설계를 테스트할 수 있습니다. 주입의 정확성은 산화물의 결함과 갇힌 공기의 위치를 추적하는 데 중요할 뿐만 아니라, 응고 결과의 핵심입니다. 올바른 주입 패턴은 주입 마지막의 올바른 열 분포를 의미합니다. 이 열 분포는 응고 분석의 기초가 됩니다.

Solidification of Castings for Foundry Applications

편석, 열응력, 마이크로 및 매크로 기공 등 응고와 관련된 다양한 결함들이 있습니다. 정확한 응고 결과를 얻기 위한 중요한 첫번째 단계는, 정확한 주입입니다. 정확한 주입은 응고 모델링의 초기 조건인 올바른 열 프로필을 캡처하는데, FLOW-3D CAST는 주조 부품을 보다 신속하게 설계하고 폐기율을 낮출 수 있는 많은 응고 관련 결함을 감지할 수 있습니다.

Validations

금속 주조 설계 과정에서 FLOW-3D CAST의 사용은 회사의 비용 절감 방안을 제시하여 수익성을 개선할 수 있습니다. FLOW-3D CAST 는 엔지니어와 설계자에게 경험과 전문지식을 향상시킬 수 있는 강력한 도구가 될 수 있습니다. 보통 수익성은 비용 절감과 비용 회피에서 찾을 수 있습니다. 지금, 품질과 생산성 문제는 제품개발 단계에서 다양한 시뮬레이션 통해 짧은 공정시간, 낮은 비용으로 해결 할 수 있는 방안을 찾을 수 있습니다. 새로운 개발도구인 FLOW-3D CAST의 효율성은 생산이 시작되기 전에 문제를 해결할 수 있는 방안을 제시하여 생산성을 크게 개선할 수 있습니다.

Ladle Pour

샷 슬리브 공정을 최적화하는 것은 고품질 부품을 확보하는 데 필수적입니다. FLOW-3D CAST의 시뮬레이션 결과와 실제 사례의 비교를 통해, 시뮬레이션을 사용하여 엔지니어가 값 비싼 툴링을 제작하기 전에 설계를 개선하는 방법을 강조합니다. FLOW-3D CAST는 프로세스 전반에 걸쳐 유체의 움직임을 정확하게 포착할 수 있으므로, 엔지니어가 실제 레들 주입 공정에서 신속하게 파악할 수 있습니다. 시뮬레이션은 Nemak Poland Sp. z o.o로부터 제공받았습니다.
