A large international manufacturing company will use two walk-in ovens to heat up molds, each weighing approximately 900 lb, to 220°F (105°C). Inside each oven is a custom rack with five shelves capable of handling up to five molds per batch.
Enhanced-duty electric walk-in oven has a top-mounted box heater with 144 kW of heat capacity. The oven is equipped with two 20,000-cfm high efficiency circulation fans that deliver dual airflow and provide uniform heat throughout the workspace.
Gas-heated walk-in oven is used for bonding composite materials inside molds. Workspace dimensions of the No. 950 measure 10 x 20 x 8’ with 700,000 BTU/hr installed in a modulating natural gas burner to provide heat.
The walk-in oven has 4” thick insulated walls and an aluminized steel interior and exterior. A four-port vacuum manifold, with pressure gauge and hand valve on each port, is included on the oven, as is a solenoid valve to bleed air into the manifold and a resin trap leading to the vacuum pump.
A supplier of composite structures will use a 500°F, vacuum-assisted composite curing oven to manufacture parts for the aerospace industry. The electric walk-in oven, supplied by Lewco Inc., includes a top-mounted heater box with 144 kW of heat capacity.
A heavy-duty walk-in oven passed the temperature uniformity requirements to meet BAC 5621 Class 1 Furnaces and Instrumentation Type D specifications. Wisconsin Oven Corp. shipped the curing oven to a composite manufacturer.
A textile manufacturer ordered eight walk-in ovens that will be used to preheat spinnerets so polymers will not stick as they are extruded through the tool. The heavy metal spinnerets weigh about 40 lb and are heated to 600°F before use. Drawers were added to the ovens to allow tools to be easily removed when needed and placed back in the oven when they cool.
An electrically heated walk-in oven will be used for composite curing small parts. It has the capability to heat 16,000 lb of a composite material from 70 to 350°F (21 to 177°C) within six to seven hours. The unit was shipped to a company in the technology industry.
