Common Mistakes to Avoid When Ordering Custom Metal Parts
Ordering custom metal parts is an exciting step in any project, whether you're working on a one-off prototype or a full production run. However, small mistakes in the ordering process can lead to costly delays, rework, or even unusable parts. At 1CutFab, we want to help you get your order right the first time. Here are the most common mistakes to avoid when placing an order for custom metal cutting.
1. Not Providing the Correct File Format
One of the biggest issues we see is customers submitting design files in incompatible formats. For precision cutting, we require vector-based CAD files such as:
-
DXF (preferred)
-
DWG
-
AI, EPS, or SVG (for simple designs)
- PDF (For Drawing dimensions and bending)
Raster image files like JPGs or PNGs won’t work because they don’t contain precise dimension data. Always double-check file compatibility before submitting.
2. Forgetting to Check Material Thickness & Type
Choosing the wrong material or thickness can lead to issues like warping, excessive weight, or poor structural integrity. Consider:
-
Thicker metal increases cost and cut time
-
Different metals have different strength and corrosion resistance
-
Check availability of the material before finalizing your design
If you’re unsure, reach out to us at 1CutFab, and we’ll help you pick the best material for your project.
3. Ignoring Kerf and Tolerance Considerations
Kerf is the width of material removed by the cutting process, and ignoring it can lead to parts not fitting together as expected. Common mistakes include:
-
Designing parts with zero clearance for slots and tabs
-
Not accounting for laser or waterjet kerf (typically 0.01”–0.04” depending on material)
-
Forgetting to specify critical tolerances for precision parts
Always allow for a small clearance when designing interlocking or fitted parts.
4. Overcomplicating the Design
While it’s tempting to go for highly detailed designs, complex shapes and excessive small cutouts can:
-
Increase cutting time and cost
-
Lead to heat buildup (in laser cutting) that can distort thin materials
-
Make small features brittle or difficult to cut accurately
Simplify your design where possible to save time and money.
5. Not Reviewing Quantity Discounts
Many customers order one or two parts without realizing that ordering in bulk can significantly reduce per-unit costs. At 1CutFab, we offer:
-
Price breaks for larger quantities
-
Optimization to nest parts efficiently on a single sheet to reduce material waste
If you’re planning multiple orders, consider ordering in bulk to save money.
6. Forgetting to Factor in Lead Times & Shipping
If you need your parts urgently, plan ahead! Common mistakes include:
-
Assuming instant turnaround—custom cutting takes time
-
Not accounting for additional processing like bending or finishing
-
Forgetting shipping time, especially for larger parts
We always aim for fast turnaround times, but planning ahead ensures you receive your parts when you need them.
7. Not Double-Checking Your Design Before Ordering
Before submitting your order, always:
-
Verify dimensions, material, and cut path
-
Ensure all elements are correctly scaled
-
Check for any unnecessary overlapping lines in your CAD file
Taking an extra few minutes to review your design can save you from costly mistakes.
