재료 및 등급 선정
주철 재료 및 등급 옵션
주철 소재 선정은 하중, 진동, 충격, 마모 및 가공 요구 사항에 부합해야 합니다. Supro MFG는 견적 제출 전에 일반적인 회주철 및 연성 주철 등급, 부품 중량, 공정 경로, 가공 여유량 및 검사 요건을 검토해 드립니다.
회주철 주물 부품
GB 표준에 따른 HT200, HT250, HT300 및 HT350을 포함한 회주철은 내충격성보다 진동 감쇠, 압축 강도 및 가공성이 더 중요한 경우에 선택됩니다. 이러한 등급은 대체로 ASTM A48 No.30, No.35, No.45 및 No.50, EN-GJL-200 ~ EN-GJL-350, DIN GG20 ~ GG35에 해당합니다. 당사는 기계 베이스, 펌프 하우징, 밸브 본체, 커버 및 엔진 블록용으로 개당 0.5kg에서 2,000kg에 이르는 회주철 주물을 검토할 수 있습니다.
연성 주철 주조품
가공이 용이하고, 피로 강도와 항복 강도가 우수하며, 내마모성도 뛰어납니다. 그러나 이 소재의 가장 잘 알려진 특성은 연성입니다. 일반적인 등급으로는 GB 표준에 따른 QT450-10, QT450-18 및 QT500-7이 있으며, 이에 상응하는 ASTM 등급으로는 65-45-12, 60-40-18 및 80-55-06, EN-GJS-450-10, EN-GJS-450-18, EN-GJS-500-7, DIN GGG-40 / GGG-50 등이 있습니다.연성 주철은 조향 조인트, 쟁기 헤드, 크랭크샤프트, 중량 기어, 승용차 및 트럭 서스펜션 부품, 유압 부품 및 자동차 문 경첩.
가단 주철 주조 부품
매력적인 가단 주철의 특성 철의 특징은 윤활제를 유지하고 저장하는 능력, 비마모성 마모 입자, 그리고 다른 마모성 이물질을 가두는 다공성 표면입니다. 가단성 주철은 하중을 많이 받는 지지면에 사용됩니다., 체인, 스프로킷, 커넥팅로드, 구동계 및 차축 부품, 철도 차량, 농업 및 건설 기계.

Cast Iron or Steel Casting?
Use cast iron when damping, machinability and cost control are more important than severe impact resistance. Use steel casting when the component requires higher tensile strength, weldability or heavy shock-load performance. If the material choice is unclear, Supro MFG can review the application and connect the project with the proper material route. View steel casting for higher strength applications.

Process Options
Foundry Process Options for Cast Iron Components
The right foundry process depends on part size, surface requirement, tolerance expectation, annual volume and material grade. We do not push every project into one route. The process is selected after drawing review.
iron green sand casting
Supro MFG has advanced die casting manufacturing equipment to meet the needs of low pressure die casting and high pressure die casting products, we provide the most cost-effective on-demand die casting manufacturing solutions for buyers from all walks of life around the world, and through x-ray, composition analysis, Non-destructive testing, mechanical testing, salt spray testing, etc., to ensure on-time delivery of high-quality die-casting parts.
iron Shell mould casting
relying on resin sand or green sand to form a cavity with the shape of the final product under the action of aluminum or steel molds, inject molten metal into the sand mold, and cool to form. Aluminum alloy sand casting is economical, but usually requires secondary machining to achieve close dimensional tolerances, and is also very effective for creating large aluminum alloy cast parts or parts with fine detail, suitable for large-scale casting projects.
At Supro casting foundry, we control the casting process and the element composition of the aluminum alloy reasonably to avoid most of the defect problems, enhance the mechanical properties, improve the casting efficiency, and make the aluminum alloy castings more competitive.
Advantages: high efficiency, low cost, economical, complex structure can be realized, suitable for a wide range of materials
Disadvantages: There are many sand holes and pores, and the surface is rough. It is impossible to build fine details.
Iron Resin sand casting
Creates steel molds and other metal molds or cores. The molten aluminum alloy is cooled and formed inside the mold. This is a reusable metal mold. More often, the aluminum alloy is injected by gravity to fill the mold cavity. Inside. The mold is then separated after cooling and the finished part is ejected or removed.
수프로 MFG uses this rapid prototyping casting process to achieve a more consistent microscopic metal structure, increase the density of aluminum alloy castings, and significantly enhance the mechanical properties of the product. It is generally used in industries with high weighing capacity, wear resistance, and 내식성. in demand.
Advantages: Higher product density Fast build time Low product cost High surface finish Finer detailing possible
Disadvantages: High mold cost Does not support design changes Not suitable for large 캐스팅 Long mold manufacturing cycle
Engineering Support
Engineering Review Before Production
A successful casting project starts before molten metal is poured. Supro MFG reviews wall transitions, sharp corners, rib thickness, boss design, core structure, machining allowance and surfaces that may be difficult to clean or machine. This review helps reduce shrinkage, sand inclusion, porosity, deformation, hard spots and machining difficulty while keeping the function of the part unchanged.
- Wall thickness, draft angle and ribs review
- Parting line, core structure and cleaning difficulty check
- Machining allowance and critical area confirmation

Buyer Questions
FAQ for Cast Iron Part Sourcing
These questions focus on RFQ preparation, material selection, inspection and post-delivery quality handling.
Please send the drawing or sample, material grade, quantity, annual volume, tolerance requirement, machining areas, surface finish, application and target delivery date. If the material grade is not fixed, our team can review the load condition and recommend gray iron, ductile iron or another route.
For 2D drawings, PDF, DWG and DXF are commonly reviewed. For 3D models, STP, STEP, IGES and OBJ can be checked. For large RFQ packages, please confirm the final accepted format with our team before submission.
Common gray iron discussions include HT200, HT250, HT300 and HT350, with related ASTM, EN and DIN references. Ductile iron discussions may include QT450-10, QT450-18 and QT500-7, with corresponding ASTM, EN-GJS and DIN grades.
Current project discussions can cover parts from about 0.5 kg to 2,000 kg per piece. Final feasibility still depends on geometry, 벽 두께, process route, machining requirements and inspection standard.
Gray iron is often selected for damping, machinability and cost control. Ductile iron is used when higher strength, toughness and impact resistance are required. The correct route depends on load, fatigue risk, service environment and machining needs.
강철 casting is usually considered when the part needs higher tensile strength, weldability or heavy shock-load performance. Cast iron is often better for damping, machinability and cost-sensitive housings, bases and covers.
Inspection can include CMM dimensional checks, spectrometer chemical analysis, mechanical property testing, destructive testing when required, non-destructive testing and final packing review. Material certificates and inspection reports can be arranged based on project requirements.
Yes. Many cast iron components require CNC machining for holes, threads, sealing surfaces, mounting faces and assembly areas. Machining requirements should be included in the quotation and inspection plan.
If a buyer reports a quality issue, the process should include photo or report review, batch traceability check, root cause analysis and corrective action. Replacement, rework or credit terms should follow the confirmed purchase agreement and inspection standard.
