Mold Pre-Heaters and Dryers

General

With the growth of water based flow coating mold washes, the need has arisen for a simple, quick, economical approach to pre-heating and drying molds processed with flow coating. Based on this need, Palmer Mfg. has teamed with a leading expert in the infrared drying market to develop a line of heaters specifically designed for the foundry mold coating industry.

Features

• Instant On / Instant Off Capability
• 0-100% Adjustable Power Output 
• Independent Lamp Zone Control 
• Integral Forced Air Blower 
• Energy Saving Idle Mode 
• Designed for both Flaskless and Flasked Molds
   

Operation

The FCS-D Series of dryers operate only on demand. Whenever the dryer is not in use or a drying cycle has expired, the heating unit will automatically shut off, eliminating the high operating costs associated with constant run gas or electric dryers. This also aides in process consistency in that molds will not become over-processed.

Available Options

• Custom Sizing
• Custom Mounting 
• Custom Hoods and Shields
• Fully Automatic Operation

Batch Type Heating

• Mold is placed under or rolls beneath drying unit. 
• Heating cycle is initiated either by operator input or automatic mold sensing switch.
• First stage heating cycle initiates infrared emitters to quickly heat the mold surface and begin to drive off water vapor and runs for a preset time. 
• Second stage heating cycle initiates operating not only the infrared emitters but also a small amount of warm forced air. This coupling of heat and air movement rapidly dries the mold surface. 
• The second stage cycle stops automatically and the mold is either pushed out or indexes as controlled by the conveying system logic.
   

Continuous Type Heating

• Mold enters a series of heaters and moves continuously through the heating unit. 
• Heating panels power upon entry of the mold and run only as required. If the panels are staged, as the mold passes the first stage, it will turn off, saving energy while the second stage or further continue to operate.
   

Mounting and Shielding

The FCS-D can be mounted in several ways. The most common approach is hanging. The heating grid can easily be suspended from hanger bolts or a free standing frame. These units are generally mounted with the grid facing a manual or powered roller conveyor but can also be mounted on angles or vertical depending on the process requirements.

These units do not require shielding as standard as the method of heating is directly on the mold surface, not a general volume. Shielding can be added for a slight increase in drying efficiency. Shields consist of high temperature canvas or the like.
