Casting Capabilities
Our casting capabilities include:
- Gravity casting for aluminum / aluminium, brass and copper alloy parts
- Permanent mold casting using reusable metal molds
- Low pressure casting for suitable aluminum components
- Resin sand cores for complex internal shapes
- Surface finishing such as anti-oxidation treatment, coating and shot blasting
- Material standards including ASTM, DIN and JIS
Materials We Cast
We support brass, copper and aluminum / aluminium casting projects based on your drawings, alloy requirement and production quantity.
Brass & Copper Gravity Casting
We support brass and copper alloy gravity casting for custom industrial parts. Common material examples include C21000, C34700 and C83800, with ASTM B806 reference standards available depending on project requirements.
Typical applications:
Aluminum / Aluminium Low Pressure Casting
For suitable aluminum parts, low pressure casting can improve surface quality, density and contour definition. Common aluminum casting materials include A319, A356, A357 and A360, with ASTM B108 reference standards available depending on project requirements.
Typical applications:
Why Choose Gravity or Permanent Mold Casting?
Gravity casting and permanent mold casting are often selected when the part requires better mechanical properties and lower porosity than typical die casting parts.
Compared with die casting, gravity casting can offer:
- Lower porosity for suitable designs
- Better mechanical properties
- Heat treatment options for selected materials
- Good dimensional repeatability with reusable molds
- Better suitability for medium-volume custom parts
Low Pressure Casting for Suitable Aluminum Parts
Low pressure casting uses controlled pressure to move molten metal into the mold cavity. The process can help improve filling control, surface quality, density and contour clarity.
For suitable aluminum parts, low pressure casting is often considered when the project requires:
- Better density than conventional gravity casting
- Improved surface quality
- More controlled metal filling
- Good mechanical performance
- Stable repeatability for production parts
Our process
Our Casting Process
We review the drawing first, choose the suitable casting route, then control tooling, casting, finishing and inspection before shipment.
-
01
RFQ & Drawing Review
Send 2D drawings, 3D models or samples. Our engineers review material, wall thickness, tolerance, surface finish and production volume.
-
02
Process Selection
We evaluate whether gravity casting, permanent mold casting, low pressure casting, sand core support or additional machining is the best route.
-
03
Tooling & Sample
Reusable metal molds are designed for the casting geometry. Resin sand cores can be added for complex internal cavities.
-
04
Casting & Finishing
Parts are cast, cleaned and finished. Surface treatment options include anti-oxidation treatment, coating and shot blasting.
-
05
Quality Inspection
We inspect material, dimensions and critical quality points before shipment.
Quality Control for Custom Casting Projects
CSMFG uses engineering review and quality control procedures throughout the project. Our team can support material verification, dimensional inspection, surface checks and third-party testing when required.
Common quality checks may include:
- Material chemical composition
- Tensile or compression strength
- Surface hardness
- Coating or treatment thickness
- Dimensional inspection
- Third-party lab testing when required
- Random QC based on AQL standards
Applications
Our gravity and low pressure casting services are suitable for custom parts used in:
- Automotive components
- Marine hardware
- Electrical apparatus
- Industrial machinery
- Housings, covers and structural parts
- Custom nonferrous metal components

FAQ
What is the difference between gravity casting and permanent mold casting?
Gravity casting often uses gravity to fill a reusable metal mold. Permanent mold casting refers to casting with reusable molds, usually made from metal. For complex internal shapes, sand cores can be added.
Do you provide copper casting in China?
Yes. We support brass and copper alloy gravity casting for custom nonferrous metal parts. Send your drawings, material grade and quantity for review.
Do you provide aluminum / aluminium gravity casting?
Yes. We support aluminum / aluminium gravity casting and low pressure casting for suitable parts.
Do you provide low pressure copper casting?
Please send your drawing and alloy requirement for engineering review. Low pressure casting is commonly used for suitable aluminum parts; copper or brass low-pressure casting should be confirmed case by case.
What industries do you serve?
Typical applications include automotive, marine, electrical apparatus and industrial machinery components.
What files should I send for quotation?
Please send PDF, DXF, DWG, STEP/STP, IGES/IGS or other available drawing files, plus material, quantity and surface finish requirements.
