BENEFITS TO LASER CUTTING

Laser cutting Balsa and Plywood is not as expensive as many might think; in fact, it is much cheaper and more convenient than old-fashioned Die Cutting.

Laser Cutting has become the standard in model manufacturing for over 10years.

Laser Cutting does not require big expense in fabricating Dies; also, parts can be up-dated very easy and at any time. 

There is no maintenance to you for Laser Cutting Files, as it is for Die Cutting. 

Laser cut balsa and plywood parts are more precise than die-crashed parts. No trimming required.

You can have your parts placed as close as you like to reduce material waist and cost. Witch means more effective payback for your time and effort investment.

 

To provided you with absolutely best laser cutting quality possible AK-Models uses true state of the art KERN Laser System and Universal Laser System for Laser Cutting and engraving services.

 

Finest cut lines, this increases precision in part fit.

Kern Laser equipped with computer controlled Air-Assist for cleaner cut. There is very minimum smoke residue on the backside of the

cutting material.  This makes your product look much more professional over other laser cutting providers.

We can cut parts up to 48" long by 24" wide.

Kern 100+ Watt laser can cut up to 1/2 birch plywood with outstanding results (see samples below). Variety of materials can be processed: softwood, hardwood, acrylic, polycarbonate, veneer. We can also cut stainless steel; shim stock and carbon steel (contact us with requirements that are more specific).

Depron Foam laser cutting can be done with outstanding results! Nice clean cuts, with no "melt away"

Aircraft plywood and thicker woods can be cut with more speed witch saves you money.


Computer Files Guidelines.

If you need AutoCAD assistance please contact:

Derek, from Juno R/C at info@junorc.com

Derek will be able to help you to transform your paper or sketch plans to Laser Cut ready files.

Please tell him AK-Models Inc referred you. 
 


AKM uses AutoCAD release 2002 and AutoCAD 2005 as our primary platform for Laser Cutting. For AutoCad users please send dwg or dxf files witch are AutoCad 2002 compatible.

We also cut and engrave your work from Corel draw 12 files.

 

File Requirements for Balsa and Plywood Laser Cutting.

 

FREE QUOTES: We will provide fast and very accurate quotes on all jobs. We ask that you send as finalized files that meet all of our requirements outlined on this page.

Make all LASER CUT LINES RED and all MARKING GREEN (if you choose to have it)

Use Txt Fonts to mark parts, text can be of any size. Do not use filled or double line fonts.

Check that ALL PARTS, lightning holes, slots etc. have brake tabs to hold them in their wood sheets. NO PARTS SHOULD FALL OUT. When cutting air pressure will blow smaller parts off, so have enough tabs to hold them in sheets. For Plywood use 0.5mm tabs and balsa 1-2mm. Make brake tabs so that they go along with the wood grain, this will make it easier to remove parts from the sheets. Best way to make brake tabs in AutoCAD is to use Multiline set accordingly to 1 or 2mm, and use it to trim the parts.

All parts must be laid-out in 12", 24", 36" or 48" long and 3", 4", 6" wide for balsa and up to 124" wide for plywood. Rectangles need to represent the raw balsa wood or plywood sheets and should be done in WHITE line. Please click image below for sample view.

LEAVE 1/8" between part and sheet's edges. THIS IS A MUST! Just of-set wood sheets edges and use it for references.

Keep all parts for each design on one file, but they must be sorted in their respective materials and include sheets size quantities and wood type next to each sheet. Use 1" letters to show wood type and quantities for each sheet. 

Send us file that represents 1 kit only, will multiply parts for you to fill your order.

Remove all un-necessary line types, text styles and fonts.

Have your name, product description and contact information in the files.

 

YOUR FILES ARE TREATED AS "CONFIDENTIAL" AND WILL NEVER BE SHARED OR USED FOR OTHER PURPOSES.

SEND ALL FILES TO: akmodelsinc@gmail.com

 

Below is an example of proper file format and set-up.

 

 

 

  GUIDELINES FOR DESIGN OF LASER CUT DEPRON SHEET KITS

Depron USA provides quality 3mm and 6mm (white and grey) Depron sheets at a reasonable price.

AK Models provides a 0.040" wide cut for 3mm and 6mm Depron sheets.

There are 25.4mm to the inch.  3mm Depron is 0.118" thick and 6mm is 0.236" thick. 

Example of factoring for a 0.040" cut width with a tab / slot: 

a.      Using 3mm Depron (0.118"), the slot width needs to be 0.078" wide.  Using 6mm Depron (0.236"), the slot width needs to be 0.196" wide.

b.      For a 0.250" slot length, the length needs to be 0.210" long.

c.      For a 0.250" tab length, the length needs to be 0.290" long.

Maintain a 0.25" distance from the 13" x 39" drawing border on CAD for all parts.  Use a 0.10" do-not-cut space on lines to be cut to retain part in sheet.  Parts around the perimeter--near the 13" x 39" border should have the 0.10" lines a little closer than those in the center.  Perimeter parts tend to receive more stress in handling and need more 0.10" lines to retain part in sheet.

Set up CAD drawing for a black background as this provides the greatest contrast for the colors to be used.  Use the thinnest red line for parts to  be cut.  Use the thinnest white line for the 13" x 39" border.

Submit drawing to AKM as a dxf or dwg file. 

Have Depron drop-shipped to AKM.  Laser-cut parts will be returned in same shipping box.

Mix kit parts with white and grey laser-cuts for optimum contrast, looks, orientation and visibility.  

Check entire drawing for stacked (double) lines.  Erase each line, refresh, and see if another line is there, then restore the desired line only.
