Project brief
프로젝트 내용
I have a metal hinge that currently works well but I need one that is longer and slightly more narrow to fit a tight space. I have remodeled the components but the nature of the hinge requires precise dimensions for it to work properly. It's a concealed hinge. I will make compression molds and the part will be made from carbon fiber. In addition. I have a locking/latching mechanism that I have about 80 percent there but need some help to get it over the finish line. This would involve an actuator and a latch that connects with a pin and applies a small amount of pressure to compress a gasket. I have CAD for both that can be provided in step or IGES format.
Because the hinge will be part of a mass-produced consumer device, it has to handle high load-bearing situations, resist corrosion in everyday environments, and survive thousands of open-close cycles without loosening or creaking. The new design should respect the original kinematics while taking full advantage of carbon fiber’s anisotropic strength. If metal inserts, bushings, or alternative pin materials are needed to reach the required durability, feel free to propose them.
For clarity, here is what I’d like back:
• Native 3D CAD model (STEP + source format)
• 2D manufacturing drawings with tolerances and recommended fiber lay-up schedule
• Basic FEA summary showing that the new geometry meets the load, corrosion-resistance, and longevity targets
• A short note on tooling considerations for compression molding, including draft angles and parting lines
I can provide any additional measurements, photos, or functional data you need. Let me know your preferred CAD platform and your estimated timeline so we can get started

지원 기회 분석
지원 전에 볼 것
예상 산출물
- 네이티브 3D CAD 모델 (STEP + 소스 포맷)
- 공차 및 섬유 적층 스케줄이 포함된 2D 제조 도면
- 하중·내부식·수명 목표 충족을 보이는 FEA 요약 보고서
- 압축 성형 툴링 노트 (드래프트 각도, 파팅 라인 포함)
매력 포인트
- 명확하고 구조화된 산출물 스펙
- STEP/IGES 원본 CAD 제공으로 착수 용이
- 복합재 설계 포트폴리오에 좋은 사례
확인할 점
- 예산 $30~250은 복합재 재설계+FEA+제조도면 대비 현저히 낮음 (평균 입찰가 $128과도 괴리)
- 기간 미기재로 일정 리스크
- 양산 소비재용 정밀 설계인데 예산 수준이 전문성과 불일치
