Kenworth Truck Frame Turnover Fixture

The assembly line at the Kenworth Truck plant requires that the truck frames be turned over after the axle and suspension components are placed on an upside down truck frame. The two synchronized hydraulic turnover fixtures grip each frame at the end of the suspension assembly line and transfer it to the beginning of the next assembly line. Each hydraulic arm is synchronized using two linear TempoSonic positioned cylinders. Using a two bar linkage design, each fixture allows a total 165 degrees of smooth rotation with only one cylinder. The unit is controlled by a single operator through an infrared controller. These turnover fixtures have been in operation since the fall of 2001.

Boeing Thermoplastic (RTL) Kevlar Duct Forming Tools

The project involved forming cylindrical ducting from flat thermoplastic composite sheets. The complete process consisted of cutting the sheet to net shape, thermoforming the flat sheet into a rough cylindrical shape, bonding the duct seam to create a closed duct, and thermoforming the ends of the duct per drawing specification.

LEI designed and directed the fabrication and assembly of several prototype tools to accomplish this process. The machinery used high temperatures and pressures to thermoform and consolidate the reinforced thermoplastic laminate material. The finished tooling was able to perform for a wide range of duct diameters and lengths.

Multi-Head Ceramic Thru Grinder

The Multi-Head Grinding tool can accommodate several grinding surfaces and product configurations. The tool uses hydraulics, pneumatics, powerful electric drives, measuring systems, lubricators and PLC controls. Custom slides and swivels were designed to position the large grinding heads. The machine incorporates a grinding fluid containment, recirculation, filtration and cooling system. Diamond grinding wheels produce fine finishes and high production rates. The machine is more than 90 feet long, 11 feet tall, and is exceptionally reliable and user friendly. 

Lund Engineering was responsible for the concept, design, engineering and support of construction.

Tempar Insulation Panel Thermal Laminating Machine

These panels are made into partitions used in refrigerated semi-trailers. The panels are 9 feet by 8 feet by 2 inches. Each panel is a sandwich construction of corrugated plastic sheets thermally bonded to a foam core. A vacuum lift system aids the operator in loading the sheets of raw material. Rollers pull the materials into the machine where radiant electric heaters melt the surfaces to be bonded. More rollers consolidate the panel, simultaneously bonding the top and bottom skin sheets. A custom saw creates a finished edge or rips the panel in half. The panels are driven off the end of the machine where they fall onto carts in stacks. The machine was designed and drafted in SolidWorks.

Lund Engineering was responsible for the prototype development, concept, design, engineering and support of construction.

Genie Industries, Electro-Coat Paint Facility Improvements

When their large electro-coat parts painting system needed a massive amount of redesign and rework Genie Industries hired LEI to help with this work. LEI handled the design modifications needed to bring the system up to operational status. Eventually this turned into a extensive amount of engineering work involving redesign and rework of the whole automated parts handling system and much of the electro-coat tanks. Other projects for Genie Industries have included the redesign of an assembly line turntable in the Scissor Lift assembly line and a rework of the lift machinery on the large hangar doors in their Moses Lake facility.
