Process Overview
Bending is a common manufacturing method to process sheet metal.
It is usually done on a Press brake, but also swing-bending-machines are used.
Forming is a form of bending, used for long and thin sheet metal parts.
Bending and Forming is typically a secondary operation after a Turret Punching machine or laser has created the necessary geometry on a flat piece of material.
The lower part of the press contains a V shaped groove.
This is called the die.
The upper part of the press contains a punch that will press the sheet metal down into the v shaped die, causing it to bend.
There are several techniques used here, but the most common modern method is "air bending".

CNC Bending & Forming Lead time
Weather you need a few prototypes or several thousand parts, we can meet your requirements quickly using the technology that is best suited for your project.
We can provide quick quotations and speedy delivery.
|
Rapid Prototyping Service
Our Rapid Sheet Metal Bending Prototyping Service (Sheet Metal Work) guarantees delivery of your parts in days instead of weeks!
Delivery time will depend on the drawings and material availability.
Post finishing could require additional 24 to 48 hours.

Production Runs
For production runs we typically have a 2-4 week lead time but can begin shipments on a weekly, bi-weekly, or daily basis to suit your needs.

Tolerances |
Our typical finished tolerances are +/- .005" (5 mils) positional accuracy, and a +/- .003" (3 mills) repeatability from part to part.
Please keep in mind that the tighter the tolerances required the more expensive a part may be.
For instance a part that has a .002" tolerance may well be 50% more expensive than a part with a .010" tolerance.
This scenario may also impact lead times. This should be taken into consideration when designing for manufacturability.

Reducing costs |
Reduce the number of bends used in your design.
Design parts to pack efficiently.
For example, in designing a large box consider making the sides of the box separate with bolted flanges.
Avoid complex bend combinations.
You can avoid the cost of bending by adding slots in place of the bends.
You can then bend the part manually.
This lowers cost further because items are flat and take less shipping volume.
Such parts also take less storage space.
