Custom Die Casting Services for Precision Metal Parts
From rapid prototyping to high-volume production, Rapzo delivers reliable aluminum and zinc die casting solutions with tight tolerances, consistent quality, and fast lead times.
What Is Die Casting?
Die casting is a high-efficiency metal manufacturing process where molten metal is injected into a steel mold under high pressure. This process makes it possible to produce complex metal parts with excellent dimensional accuracy, smooth surfaces, and consistent repeatability.
Rapzo provides custom die casting services for customers who need precision metal components with reliable quality and cost-efficient production.
- Suitable for complex geometries and thin-wall structures
- Ideal for medium to high-volume production runs
- Excellent dimensional consistency across batches
- Strong surface finish potential for functional and visual requirements

Prototype to Mass Production
From early-stage validation to stable long-run output, Rapzo supports the full manufacturing lifecycle.
Die Casting Process
Every precision die cast component follows a structured process designed for consistency, efficiency, and part quality.
Engineering team reviews part geometry and designs the die mold for dimensional accuracy, flow characteristics, and long-term tooling durability.
Molten aluminum or zinc alloy is injected into the steel mold cavity under high pressure, filling complex geometries with precision and speed.
The injected metal solidifies within the mold under controlled cooling conditions to ensure consistent part dimensions and structural integrity.
Once solidified, the part is ejected from the mold using ejector pins, maintaining the dimensional accuracy established during the injection stage.
Flash, gates, and runners are removed. Secondary operations such as machining, drilling, or surface finishing are applied as required.
Each batch undergoes dimensional inspection, surface verification, and traceability documentation before shipment approval.
Surface Finishing Options
To meet both functional and visual requirements, Rapzo offers a range of surface finishing solutions for die cast parts.
Powder Coating
Improves durability, corrosion resistance, and appearance for industrial and commercial applications.
Polishing & Surface Smoothing
Enhances visual quality and removes minor imperfections for parts requiring a cleaner finished look.
Additional Finishing Options
Depending on the application, die cast parts may also receive painting, anodizing, sandblasting, or custom post-treatment solutions.

Frequently Asked Questions
Common questions about Rapzo's die casting services and capabilities.
Rapzo supports flexible production volumes. While die casting is most cost-efficient at medium to high volumes due to tooling investment, we work with customers to determine the most practical approach based on their project requirements and budget.
Die casting can achieve tight dimensional tolerances depending on part geometry, material, and mold design. Rapzo's engineering team works with customers to define achievable tolerances based on the specific part requirements and applies precision inspection to verify conformance.
Mold lead time varies based on part complexity, size, and design requirements. Rapzo provides estimated tooling timelines during the quotation stage. Once the mold is approved and production begins, lead times for parts are significantly shorter.
Yes. Rapzo provides secondary operations including CNC machining for tight-tolerance features, surface finishing such as powder coating and polishing, and assembly support. This one-stop approach reduces coordination complexity and ensures consistent quality throughout the full production process.
