Lindberg/MPH Ships Hot Stamping Furnace to Gestamp Research and Development Facility

Riverside, MI – July 30, 2019 – Lindberg/MPH announced the shipment of an Electrically Heated Four Chamber Hot Stamping Furnace to the Gestamp Research and Development facility located in Auburn Hills, MI. Gestamp is an international corporation that designs, develops, and manufactures metal automotive components.

This hot stamping furnace features one stack of three high heat chambers and one low heat chamber. The maximum temperature rating of the high heat chambers is 1050°C and the low heat chamber is 540°C. Each furnace chamber was designed with load space dimensions of 36” W x 30” D x 8” H.

The furnace is integrated at the Gestamp facility with a robotic transfer system and hydraulic hot stamping press. The four chambers operate independently with the top chamber designated for aluminum treatment. This type of hot stamping system allows the customer the flexibility to treat different steels simultaneously and takes up a much smaller footprint than a continuous system.

“This Lindberg/MPH hot stamping furnace provides uniform heating for a wide variety of high-strength steels or aluminum materials prior to hot stamping or hydro-forming applications. The team at Gestamp has been incredible to work with on this project and we are proud to be their supplier.” – Bill St. Thomas, Business Development Manager

Unique features of this Lindberg/MPH hot stamping furnace include:

  • Hydraulically actuated, independently controlled furnace doors
  • Exterior fans to provide cooling between the four heating chambers
  • Two heating zones of rod-overbend elements in each chamber
  • Allen Bradley Compact Logix PLC with temperature control and logic functions
  • One (1) dew-point monitor connected to sample tubes in each chamber
  • Ethernet and Modbus-485 communication capabilities
  • Excess temperature controller in each chamber

Lindberg/MPH Ships Aluminum Melting and Holding Furnace

Lindberg/MPH announced the shipment of an Aluminum Melting and Holding Furnace. The melting and holding furnace was designed with an aluminum melt rate of 3,000 lbs per hour and the capacity to hold up to 40,000 lbs of aluminum.

The aluminum melting and holding furnace will be loaded with aluminum across a preheat hearth. prior to being pushed into the molten aluminum bath. An exterior discharge well and working tap are included with the furnace as a means of aluminum removal. The equipment also features a circulation well for improved temperature and alloy uniformity.

This custom melting and holding furnace will be in the production of aluminum powder. Temperature of the metal is controlled through digital temperature controllers. Flue gases are controlled with a mechanical flue damper, reducing flue losses during low-fire operation. A totalizing gas meter was also included to accurately measure gas usage.

“The Lindberg/MPH engineering team worked closely with the customer on a custom design that met their application requirements. A factory trained technician supervised the installation of this custom furnace and performed the initial start-up to ensure that everything went smoothly.” ~Andrew Paul, Sales Representative

Unique features of this Lindberg/MPH aluminum melting and holding furnace include:

  • Rugged fully welded steel plate furnace construction
  • High alumina castable lining for long refractory life backed with high efficiency insulating materials
  • One charge door and one side access door for easy access during charging and cleaning
  • Flue damper for energy savings during low-fire operation
  • Work and drain taps
  • Jib crane for molten metal pump insertion and removal
  • Laser metal level sensor
  • Stand-alone control panel
  • Programmable logic controller controls furnace functions and records status history
  • Temperature controllers with automatic preheat and dry out functions
  • Three-point laser metal level sensor with light tree level indication.
  • Totalizing gas meter
  • Start-up and installation service

Pit Furnace for Heat Treating Aircraft Components

pit furnaceLindberg/MPH announced the shipment of a cyclone pit furnace to a supplier of the aerospace industry. The pit furnace performs a heat treating process on aircraft components. The cyclone design has historically provided optimum heat distribution and exceptional temperature uniformity which makes it ideal for applications such as tempering, normalizing, solution treatment of aluminum and annealing.

This heat treating pit furnace has a maximum temperature rating of 1250º F. The work chamber is 16″ in diameter with a depth of 20”. This cyclone pit furnace is a direct replacement of an existing piece of Lindberg/MPH equipment the customer already had in place. Lindberg/MPH provided a centralized control system with a programmable logic controller to control this equipment and six other furnaces. The cyclone pit furnace design utilizes a heater plug assembly that is easily lifted out and replaced externally without having to pull elements out through the furnace walls for easy maintenance.

“This customer was looking to improve their efficiency of operating their furnace line. By providing a control system that allowed them to monitor and control multiple units, it greatly simplified the customer’s process and fulfills their data acquisition needs.” Jason Dobberstein, Inside Sales Manager

Unique features of this cyclone pit furnace include:

  • Alloy liner protects work chamber from high velocity flow and prevents damage while loading/unloading
  • Easily replaceable heater plug assembly
  • Recirculating fan with variable frequency drive
  • Workload support
  • Lid limit switch
