Great Lakes Aero Products, Inc.

Great Lakes Aero Products, Inc. makes aircraft windshields and windows for general aviation. The company says making windshields is what it does best. Its work includes parts for non-pressurized Part 23 aircraft and for some Part 25 aircraft.

The company builds molds and dies on site. It can also modify dies that a customer supplies. Its tool and die makers have more than 40 years of combined experience. The company makes blown or formed parts and complicated acrylic parts, such as wing tip lenses with good optical characteristics. It also assembles vent windows, attaches fiberglass rings, casts small urethane parts and mills edges to size.

Most aircraft manufacturers require the LP-391 specification. The company can also work to ASTM D4802, which it describes as basically the same but in metric units. For projects that need to exceed these specifications, it says it hand selects materials. It also says it works quickly to get FAA PMA for production parts.

The company focuses on consistent shape and trim from one shipment to the next. It says its parts should need little or no trimming at installation. It says aircraft manufacturers who buy from it rely on this consistency.

The company has also made transparent parts for other fields. These include windshields and windows for concept cars and race cars, custom car windows, classic car reproduction parts, boat and motorcycle windshields, and specialty acrylic and polycarbonate projects.
