How do you prevent water ingress at cable entry points?

Cable entries use sealed glands with rubber grommets positioned at the bottom or side as specified, combined with internal drip channels to route condensation away from equipment.

제품 개요

이 맞춤형 판금 벤딩 가공품은 주거용 및 상업용 에너지 저장 시스템과 AC/DC 전기차 충전기의 내부 구조 부품으로 특별히 개발되었으며, 모듈 보호 케이스, 위치 고정 마운팅 브래킷, 고정 지지 프레임, 절연 차폐 셸 및 보강 벤딩 플레이트 등을 포함합니다. 회로 기판, 배선 하니스, 변압기 및 전기 모듈을 안정적으로 고정하도록 설계된 이 제품들은 충전 및 에너지 저장 장비 내부에서 절연, 구조 보강, 진동 저항 및 내부 공간 배치에 중요한 역할을 합니다.

당사가 해결한 주요 처리 과제(핵심 경쟁력)

얇은 판의 굽힘 변형 문제 해결

초박형 냉간압연 강판/알루미늄 합금판은 굽힘 후 뒤틀림과 휨 현상이 발생하기 쉽습니다. 당사는 맞춤형 벤딩 금형과 분할 압력 성형 공정을 통해 휨 값을 정밀하게 제어하고 성형 후 평탄도를 엄격한 범위 내로 보장합니다.
복잡한 다각도 및 심부 인발 굽힘 공차 편차 극복

불규칙한 다중 굽힘 접힘 브래킷의 경우, 기존 가공 방식으로는 치수 허용 오차를 벗어나기 쉽습니다. 당사의 사전 프로그래밍된 CNC 굽힘 보정 기술은 전체 허용 오차를 ±0.1mm 이내로 유지하여 내부 전자 모듈의 고정밀 조립 요구 사항을 충족합니다.
2차 굽힘 후 동축 구멍 위치 편차 문제 해결

굽힘선 근처의 구멍은 성형 후 위치가 변하는 경우가 많습니다. 당사는 굽힘 전 위치 지정 구멍 배치와 성형 후 정밀 보정을 통해 구멍 중심 정렬을 보장하고, 강제로 끼워 맞추지 않고도 나사 조립이 원활하게 이루어지도록 합니다.
좁은 굽힘 홈에서의 고정 모서리 붕괴 및 버 결함

좁고 깊은 벤딩 슬롯은 가장자리가 무너지고 거친 버가 생기기 쉽습니다. 당사는 특수 소형 벤딩 펀치를 사용하고 후가공 단계에서 완벽한 버 제거 작업을 통해 내부 부품 설치 시 가장자리가 깔끔하고 흠집 없이 유지되도록 합니다.

당사 공장의 강점 및 장점

모든 공정을 사내에서 한 번에 처리하는 판금 가공 워크플로우

레이저 절단, CNC 정밀 벤딩, 탭핑, 리벳팅, 연삭, 표면 마감 등 모든 공정을 자체 보유하여 아웃소싱 없이 비용 관리가 용이하고 생산 과정 전반을 추적할 수 있습니다.
신에너지 구조 구성 요소 분야 전문 경력

전기차 충전기 및 에너지 저장 장치 내부 브래킷 및 하우징에 대한 다년간의 심층적인 가공 경험을 바탕으로, 전력 장비의 내부 조립 논리, 방열 배치 및 간섭 방지 구조 설계에 정통하며, 조립 불량률을 줄이기 위한 DFM 구조 최적화 제안을 제공할 수 있습니다.
엄격한 배치 일관성 품질 관리

최초 생산품 검사, 공정 중 치수 검사 및 모든 배치에 대한 완제품 전체 샘플 측정을 통해 대량 생산 시 크기 변동을 효과적으로 방지하고 장기 주문 협력을 위한 안정적인 납기를 보장합니다.
유연한 맞춤형 서비스

도면/샘플 기반의 OEM 및 ODM 맞춤 제작이 가능하며, 재질(SPCC, SGCC, 알루미늄, 스테인리스강), 두께, 벤딩 구조, 홀 위치, 표면 처리(분체 도장, 브러싱, 부동태 처리), 맞춤형 로고 마킹 등을 조정할 수 있습니다.

응용 시나리오

7kW/11kW/22kW AC 가정용 충전기, DC 고속 충전기, 가정용 에너지 저장 배터리 캐비닛, 산업용 에너지 저장 캐비닛 제어 모듈, 독립형 에너지 저장 발전소 내부 조립 액세서리용 내부 구조 브래킷 및 모듈 보호 쉘.
