What materials can you cut and fabricate?

We cut rubber, silicone, neoprene, EPDM, cork, fiber, acrylic, glass, foam, and other sheet materials into custom shapes. Use the configurator to select your material, shape, and dimensions for an instant price.

How do I get an instant price for a custom cut part?

Use the configurator on this page. Select your shape, material, and thickness, enter your dimensions, and the price updates live. No quote request, no back-and-forth.

What shapes can you cut?

We cut over 30 shapes including discs, rings, rectangles, squares, capsules, ovals, hexagons, D-shapes, and custom polygons. Upload a DXF file for fully custom shapes.

Is there a minimum order quantity?

No minimum. We cut single pieces as readily as bulk orders. Price per piece decreases automatically with quantity.

How long does production take?

Most custom fabricated parts are cut and shipped in about 1 week.

What is the maximum size you can cut?

The maximum size depends on the material you choose. Most rubber, silicone, neoprene, EPDM, cork, fiber, and glass sheets go up to 32.5 x 32.5 inches, and acrylic sheets up to 23.5 x 23.5 inches. The configurator tells you if your part is too large for the selected material. Contact us for larger parts.

Do I need to send a file?

No file needed for standard shapes. The configurator generates the cut geometry from your dimensions. For fully custom shapes, you can upload a DXF file.

Custom Rhombus Parts Cut to Size

View full details

Need diamond-shaped parts? Enter your dimensions, pick a material, and the quoter prices the part right away. No minimum order, so one-offs and prototypes are fine.

A rhombus is a diamond with four equal sides. Enter the horizontal and vertical diagonals and the quoter builds the shape. Rhombus parts are used for tile and mosaic pieces, signs, inlays, display parts, spacers and pads.

Materials: Acrylic in clear, frosted, white, black and colors (acrylic edges come out flame-polished), polycarbonate, glass and mirror, plus neoprene, EPDM, silicone, Buna-N, cork and fiber.

How it's made: every part is CNC cut (laser, waterjet, and more) to ±0.015″. We don't cut tempered glass. Order one part or a few hundred; every piece in a batch is cut from the same file, so they all match.

Related: parallelogram, kite and trapezoid parts.

What you enter: Width (horizontal diagonal), Height (vertical diagonal). Pick inches or mm in the quoter.

Size: Up to 32.5″ × 32.5″ for most materials. Glass, mirror, polycarbonate, Viton and PTFE top out at 18″ × 12″, and borosilicate at 12″ × 12″; the quoter shows the exact limit for each material.

FAQ

What do I measure for a rhombus?

The two diagonals: corner to corner across the width, and corner to corner across the height.

Is a diamond the same as a rhombus?

Yes. A diamond shape with four equal sides is a rhombus.

Can acrylic diamonds be cut in color?

Yes. Acrylic comes in clear, frosted, white, black and several colors.

Is there a minimum?

No.

How fast does it ship?

Most orders ship in 1 week.

Which material should I pick?

Full list on our Material Guide.

Pads, spacers, general rubber parts → Neoprene
Flexible rubber, wide temperature range → Silicone
Weather, water and ozone → EPDM
Oil and fuel contact → Buna-N
Low-pressure seals and spacers → Cork, or Fiber for simple cut shapes
Displays, covers, see-through parts → Clear acrylic (also frosted, black, white)
Guards and covers that need impact resistance → Polycarbonate
Glass panels and sight openings → Clear glass, frosted glass or mirror

How to measure

Measure the finished cut size you need, not the rough stock.
Discs: diameter across the widest point. Rectangles: length × width. Rings: outside diameter (OD) and inside diameter (ID). Other shapes: follow the fields on that product.
A tape measure is fine for most parts. Calipers help on small pieces.
Pick material and thickness in the quoter.
Fully custom shape? Upload a DXF. No CAD? Send us a sketch with measurements.
