Precision Tool & Die Making Demands Strict Process Control
Manufacturing a complete stamping die goes far beyond simple machining. The real challenge lies in designing an optimal strip layout, controlling micro-clearances, and ensuring stable material feeding during high-speed continuous production.
At Sundi MFG, we don’t just assemble metal plates. Before cutting any steel, our engineering team thoroughly evaluates the die structure, tonnage requirements, and material selection (incorporating premium tungsten carbide for high-wear areas) to prevent premature wear and tool failure.
To guarantee flawless stamping performance, we integrate advanced wire EDM, profile grinding, and CNC machining. Most importantly, every complete die set undergoes meticulous hand-fitting by our master diemakers and rigorous in-house press trials to verify the sample strips before shipping.

Why We Provide Engineer-Reviewed Quotes
Custom tool and die manufacturing depends heavily on part complexity, strip layout design, required tolerances, and core material selection. That is why we do not rely on automatic online pricing algorithms. Every 2D/3D drawing is carefully reviewed by our engineering team before quotation, ensuring we provide you with the most accurate price, realistic lead time, and an optimized tooling plan.
Our Ordering Process
We are a direct-to-factory manufacturer, not a brokered quote platform. Every component is engineered, machined, and inspected in-house at Sundi. This ensures complete control over technical precision, production lead times, and data security from your initial drawing to final delivery.
Send RFQ
Submit your 2D/3D CAD models and technical specifications via our secure online form or direct email.
Review & Quote
Our technical team evaluates your drawings for manufacturability and provides a detailed, data-driven quotation within 12 hours.
Confirm Order
Finalize technical parameters, confirm tolerances, and lock in the production schedule prior to contract sign-off.
Production
CAM programming is executed, and production begins across our specialized CNC, EDM, or stamping lines.
Quality Inspection
In-process dimensional checks and a comprehensive final inspection ensure all parts meet specified tolerances before leaving the floor.
Packaging & Shipping
Components are meticulously packed using dedicated protective materials to prevent transit damage and shipped globally.
Tool & Die Making FAQs
What drawing formats do you accept for tool and die quoting?
Please provide 3D models (STEP, IGES, X_T) for the overall structure, along with 2D drawings (PDF, DXF/DWG) specifying critical tolerances, material grades, and surface finish requirements.
Do you manufacture plastic injection molds?
We currently focus exclusively on engineering and building complete metal stamping dies. However, we do manufacture high-precision custom mold components for the plastic injection industry, such as custom ejector pins, core pins, and precision cavity inserts.
What is the expected lifespan of your progressive stamping dies?
Depending on the selected core materials (such as premium Tungsten Carbide) and stamping conditions, our high-speed progressive dies are engineered to deliver millions to tens of millions of strokes with proper routine maintenance and regrinding.
Do you supply replacement spare parts for the dies you build?
Absolutely. We securely archive all your tooling designs. Whenever you need replacement punches, die inserts, or guide components, we can quickly machine and ship them to minimize your production downtime.
What is the typical lead time for a complete progressive die set?
Designing, manufacturing, assembling, and testing a complete progressive die typically takes 4 to 6 weeks, depending on the part’s complexity, station count, and required press trials.
