3D Sand Mold and Casting Service

From initial concept to final delivery, our comprehensive services cover every step of the product development process.

3D Sand Mold & Casting

At XM Group, we offer sand casting service that integrates the precision and speed of 3D printing. This powerful combination allows us to deliver complex metal prototypes and low-volume production parts with unparalleled speed, intricate detail, and superior quality. 3D printing technology for creating sand molds is a game-changer for the sand casting industry, enabling unprecedented design freedom and speed.

Our Casting Capabilities

XM Tech has streamlined the sand casting process to deliver exceptional results with maximum efficiency:

Digital Design Submission: You provide us with your 3D CAD model.
Mold Printing: Leveraging our advanced 3D printers, we create a precise sand mold and any necessary cores directly from your digital file. Our printers use a binder jetting process, where a liquid binder is selectively deposited onto a thin layer of sand, building the mold layer by layer.
Mold Assembly and Preparation: The 3D-printed mold sections are meticulously cleaned and assembled, ready for casting.
Casting: Molten metal of your choice is poured into the precisely created mold cavity within our large-scale foundry.
Cooling and Finishing: Once the metal has solidified, the sand mold is broken away, revealing the metal part. The casting then undergoes finishing processes to meet your exact specifications.

Technology: Binder jetting or resin-printed sand molds.
Benefits:
- Produce functional prototypes & production parts in days (vs. weeks).
- Optimize designs with iterative mold adjustments at minimal cost.
- Achieve fine details & thin walls impossible with traditional methods.
Applications: Engine blocks, pump housings, large industrial parts.

Our 3D-printed sand casting service supports a wide range of ferrous and non-ferrous metals, including but not limited to:

Aluminum Alloys
Steel Alloys
Iron
Bronze

This versatile process is ideal for a multitude of applications across various industries that demand high-performance, complex metal components, such as:

Aerospace: Intricate engine components, housings, and brackets.
Automotive: Prototyping of engine blocks, cylinder heads, and suspension parts.
Industrial Machinery: Complex pump housings, valves, and impellers.
Robotics: Customized structural components and end-effectors.
Energy: Turbine blades and other power generation components.

Frequently Asked Questions.

What file formats do you accept for quoting and manufacturing?

We support all major CAD formats:
STEP, IGES, STL, SLDPRT, X_T, PARASOLID (and more).
Our engineers will review your design for manufacturability (DFM) and provide optimization suggestions before production begins.

What materials do you work with?

We offer a wide range of materials for various manufacturing processes, including:

Metals (Aluminum, Steel, Titanium, etc.)
Plastics (ABS, Nylon, Polycarbonate, etc.)
Composites and specialized materials depending on the application. We also provide material consultation to help you select the most suitable materials for your project.

Can you handle complex geometries or tight-tolerance parts?

Absolutely. Our 5-axis CNC machining centers (±0.01mm) and industrial 3D printers excel at:

Intricate designs, thin walls, and internal features
Tolerances down to ±0.025mm for critical dimensions
Challenging materials (e.g., Inconel, PEEK, tool steels)

Can I request a custom finish or post-processing for my parts?

Absolutely! We offer a wide range of surface finishes and post-processing options to enhance both the appearance and functionality of your parts. Whether you need polishing, anodizing, painting, or another specific finish, we can accommodate your requirements.

What is the lead time for your services?

Lead times vary depending on the service and project complexity. Rapid prototyping can typically be completed within a few days, while more complex manufacturing projects such as low-volume production or tooling may take longer. Once we receive your project specifications, we’ll provide a detailed timeline.
