Fast turnarounds to keep your projects moving

Strengthen your parts without adding weight. Dimple forming is a simple way to increase rigidity while keeping production fast.

Increase strength without adding weight

Dimples add stiffness to flat sheet metal, reducing flex and improving structural integrity without increasing material thickness.

Quick to add, no delays

Dimple forming is performed in-house, adding only +1–3 days to standard production

Flexible materials and sizes

Available on 7+ metals and a wide range of thicknesses, with dimple sizes up to 3″ diameter and part sizes from small brackets to large panels.

“Designed an aluminum skidplate with dimple dies on Sunday and received it on Wednesday.”

Design guidelines for dimple formed parts

Following a few basic design guidelines will help ensure your parts are dimple formed correctly and pass SendCutSend review.

Sizing requirements

Sizing limits apply to flat parts before bending

Min part size (flat)	Depends on dimple selected (see chart below)
Max part size (flat)	26″ x 56″
Max hole size	4.00″ – holes auto-resize to match your dimple selection
Dimple width positioning	7″–19″ from edge, measured from dimple center

Minimum part sizes based on the dimple used:

Dimple size (A)	Min part size (B)	Min distance to edge from dimple center (C)
0.500″	1.200″	0.600″
0.750”	1.450”	0.725″
1.000”	1.950”	0.975″
1.250”	2.450”	1.225″
1.500”	2.700″	1.350″
1.750”	3.200”	1.800″
2.000”	3.470”	1.735″
2.500”	4.450”	2.225″
3.000”	5.200”	2.600″

Spacing & clearance

Keep dimples away from other features — holes or cutouts too close to the dimple die will deform during forming. Space dimples from bend lines by adding min feature distance (D) + half the bend allowance for your material and bend angle. Use the Bend Calculator to find your bend allowance.

Dimple Tool OD (A)	Dimple Major (B)	Dimple size / Minor (C)*	Min distance to other features (D)	Min distance dimple center to bend line (E)	Min distance to the same dimple (F)
1.200″	0.850″	0.500″	0.600″	0.600″ (D) + 1/2 the bend allowance for material thickness & bend angle	1.200″
1.450″	1.150”	0.750”	0.725”	0.725″ (D) + 1/2 the bend allowance for material thickness & bend angle	1.450”
1.950″	1.575”	1.000”	0.975”	0.975″ (D) + 1/2 the bend allowance for material thickness & bend angle	1.950”
2.450″	1.875”	1.250”	1.225”	1.225″ (D) + 1/2 the bend allowance for material thickness & bend angle	2.450”
2.700″	2.200”	1.500”	1.350”	1.350″ (D) + 1/2 the bend allowance for material thickness & bend angle	2.700″
3.200″	2.500”	1.750”	1.600”	1.600″ (D) + 1/2 the bend allowance for material thickness & bend angle	3.200”

4.450″	3.600″	2.500”	2.225”	2.225″ (D) + 1/2 the bend allowance for material thickness & bend angle	4.450”

What to expect with dimple formed parts

Process order: Dimple forming is performed after tapping, countersinking, deburring, and tumbling and before bending, hardware, and finishing services.
Material behavior: Dimple forming can cause slight bowing or warping depending on material type, thickness, and geometry. Adding a bent flange can help reduce this.
Tooling marks: Visible on all dimple formed parts and may show through finishing processes like powder coating, anodizing, or plating.
Witness marks: May be present even after tumbling and deburring.
Feature deformation: Holes or features too close to a dimple may distort during forming.
Dimensional variation: Dimple height and minor diameter are approximate and may vary based on material and thickness.
Finishing impact: Powder coating adds .002″–.005″ per side and may result in tighter fits around dimples.

If you’re designing parts for dimple forming, these resources may help:

Pre-flight checklist

File is in a format that we accept (2D: .dxf, .dwg, .ai, .eps; 3D: .step or .stp)
All holes and cutouts are at least 50% material thickness for laser cut parts
All holes and cutouts are no less than 0.070” for most waterjet cut parts
All holes and cutouts are no less than 0.125” for all CNC routed parts
File is built at a 1:1 scale, preferably in inch or mm units
2D files: all objects on the same layer, text converted to outlines, no open contours, all shapes united or merged, floating interiors bridged or stencilized
3D files: single solid sheet metal body, uniform thickness with a face at every edge, modeled at stock thickness with matching bend specs
All stray points, duplicate lines, empty objects and text areas have been removed

  Quick Service and amazing quality.  I have never had the privilege of welding on such clean steel.  I only paid for basic cut and de-burring and this is what I got back.  Now I can consider projects that I have avoided since I have no plasma cutter or CNC equipment.  Price was very reasonable so I would give 6 stars if I could!

  Such a great service. Like with any growing company, there might be some hiccups here and there, but their customer service is excellent. Julie in particular was super helpful in getting a delayed order to me exactly on time! Will keep using SendCutSend for my custom car parts ....
