In precision manufacturing, a great product always begins with a great design. That’s where Design for Manufacturability (DFM) comes in — a methodology that bridges the gap between product development and cost-effective, scalable manufacturing.
Whether you’re using CNC machining or die casting, we provide professional DFM support to help you reduce machining errors, shorten lead times, and ensure your parts are built right the first time.
Why DFM Matters for CNC Machining and Die Casting
CNC machining and die casting are two very different processes — yet both benefit significantly from DFM:
-
CNC machining deals with tool paths, tight tolerances, and multiple axes.
-
Die casting involves mold design, draft angles, material flow, and cooling behavior.
If the design doesn’t take these realities into account, your project may face high manufacturing costs, production delays, or even part failure. That’s why DFM is not optional — it’s essential.
Designing Parts for Easy Machining Saves Time and Money and Increases the Likelihood That the Parts Will Be Delivered to You at Quality.
Our DFM Services Cover Both CNC and Die Casting Processes
We don’t just manufacture your parts — we help you design them better. Our engineering team reviews your CAD files and technical drawings and provides detailed DFM feedback, focusing on:
1. Drawing & Model Review
-
Check for complete 2D drawings: materials, tolerances, surface finish, threads, critical dimensions.
-
Inspect 3D models for manufacturability issues, interference, or missing constraints.
2. Tolerance Optimization
-
Recommend practical tolerances: e.g. ±0.01mm ~ ±0.05mm for CNC; avoid unnecessarily tight specs.
-
Apply GD&T where needed to reduce accumulation errors in assemblies.
3. Machinability & Casting Feasibility
For CNC parts:
-
Align features to common datum points.
-
Avoid thin walls, deep pockets, and overly complex geometries.
For die cast parts:
-
Analyze parting lines, draft angles, uniform wall thickness.
-
Suggest adjustments to reduce shrinkage, porosity, and warpage.
4. Material Selection & Stock Sizing
-
Recommend using standard material sizes to minimize waste and cost.
-
Suggest suitable alloys: e.g. aluminum (ADC12, A380) or zinc (Zamak 3) for die casting; stainless steel, titanium, and aluminum for CNC.
5. Cost-Saving Strategies
-
Identify features that increase cost unnecessarily (e.g. mirror finishes, sharp internal corners).
-
Compare the cost-efficiency of CNC vs die casting for your application.
CNC vs Die Casting: Which is Right for You?
| Process | Ideal Volume | Precision Range | Cost Model | Material Options | Typical Applications |
|---|---|---|---|---|---|
| CNC Machining | Low to medium | ±1μm to ±10μm | Time-based, flexible | Aluminum, stainless steel, titanium, etc. | Fixtures, optical parts, medical |
| Die Casting | Medium to high | ±0.05mm to ±0.1mm | High tooling, low unit | ADC12, A380, Zamak 3, magnesium alloys | Housings, brackets, heat sinks |
