These ovens are often referred to as sand core dryers, mold dryers, or core drying ovens. The sand core dryer evaporates the water and leaves the graphite behind. Sand core and mold drying ovens are used throughout the foundry industry to prepare a variety of molds and cores. Before sand molds and cores can accept the molten steel, aluminum, or other metal they must be dipped or sprayed with a core wash on the interior. The sand casting process starts with a refractory wash that provides a better surface finish on the casting, protects the sand mold from the heat as it enters the mold cavity, and prevents the metal from sticking to the mold during cooling.

After being applied, the wash must be dried, most commonly in a conveyor oven. GBM Oven’s sand core drying ovens use high-velocity impingement and other technology to increase energy efficiency and decrease drying time which results in an increased production rate and a reduced cost per part.

Advantages of Sand Core Drying Belt Conveyor Oven:

The Foundry Industry relies on GBM Industries as the “preferred” company when it comes to Sand Core Drying Ovens. GBM Sand Core Dry ovens are used to dry water -based coatings that are applied to sand cores. GBM will develop and perform tests for each core drying application for proper moisture removal at the minimum time and temperature.  We don’t rely on gimmicks and marketing ploys when it comes to designing our ovens.  Proper air flow is the key to moisture removal and is proven in our Process Development Center at the time of quoting each project.  GBM offers convention and custom designed drying systems for unique shaped cores.  Bring your cores to GBM and let us prove the results to you!

Standard design features include:

• Variable speed flat-wire belts. These provide the ability to convey heavy loads while allowing air flow through the belt.
• The open design also allows coatings to be removed in an optional wash cleaning stage. 
• Belting is allowed to pass through a water rinse station utilizing agitation brushes which remove excess core wash left on the belt once the dried cores are removed.
• Heated by a natural gas burner or electric heat
• Mild Steel base structure with heavy gauge HR/CR  insulated walls
• Industrial rated and factory supported controls
• Energy efficient insulation
• Safety equipment designed to meet your facility requirements

Common features available:

• PLC/HMI systems
• Process timers
• SCADA/paperless chart recordings
• Ethernet communications
• Installation, installation supervision, start up and operator training
