Project Background:

Cascade Corporation of Springfield, OH is a multi-national manufacturer of forklift attachments. The engineers had a specific preheating application that was required for an assortment of parts that would be welded to forklifts. The parts required a specific target temperature of 400°F to prepare them for welding. A large capacity, floor-positioned, front-loading preheat oven was requested with removable shelves so that the parts could be easily removed.

We recommended a modified K-1000 which became the K-1000M for this project. The standard K-1000 has a shorter depth and hexagonal shelving, but the width and height were suitable for the number of parts Cascade needed to preheat. The K-1000 was redesigned by increasing the depth and by installing six, flat, perforated shelves with the appropriate load capacity. The shelves slide in and out on tracks that are tack welded to the inside of the oven. A simple, dial adjustable thermostat with bimetal thermometer combination was requested and delivered.

Oven Construction


The K-1000M heat treating oven is constructed of carbon steel throughout. The oven exterior has a highly durable, powder-coat finish in blue that is resistant to scratching and corrosion. This a front-loading, floor-positioned preheating oven and is designed to be stored on a floor for ease of access to the parts being preheated.

Forklift slots are welded to the bottom of the oven to facilitate movement. The door hinges are tack-welded to ensure smooth operation for many years. The control panel which houses the dial adjustable thermostat is mounted on the side of the oven with heavy-duty rivets. A standard "ON/OFF" indicating light was also provided, which is bright enough to be seen from a distance. A variety of temperature control methods are available at preheatovens.com.


The shelves of the K-1000M preheat oven are flat and removable along tack welded tracks in the side walls of the unit. The shelves are perforated which allows the heat from underneath to radiate through the shelf and heat the parts effectively. Various shelving styles are available at preheatovens.com suitable for almost any custom preheating application.

There are five 1000W tubular elements installed on the the base of the oven which allows the heat to radiate upwards and around the oven.The interior of the K-1000M preheating oven is painted with a reflective, galvanized paint and the interior welds are touched up with high-temperature aluminum paint.

All our preheating ovens are made in the USA and feature a 1-year limited manufacturer's warranty. Parts are readily available.
