One company that has taken design and form

information to the Internet is Lehi

Sheetmetal, Westboro, MA

(www.lehisheetmetal.com).

Standard dies, punches and manufacturing

equipment such as brakes and turrets are

listed in the Engineering helpers section.

Dimensions are provided for their standard

forms. The form tool you used for this ~----3

project creates a 32mm x 6mm louver. The

tool is commercially available.

Your manufacturer only stocks 3in. (75mm)

and 4in. (lOOmm) louvers. Work with the

sheet metal manufacturer to obtain a cost

effective alternative. Create a pattern of

standard square cuts to dissipate the heat.

If a custom form is required, most custom

sheet metal manufacturers can accommodate

your requirement. Example: Wilson Tool,
