Plate Heaters

Platen Form and Groove Coil Heater:

Plate Heater

Precision plate and component heater assemblies are designed for a wide range of extrusion, molding and packaging applications. The rugged, high performance assemblies provide exceptional performance in the heating of extrusion profile dies, blow-molding manifolds and die heads, wire cross head dies, extruder barrels, polymer pumps, and injection molds.

Aluminum Platen Heaters:

a

Cast-in platen heaters are used in a wide variety of applications, which require a uniform heat source such as plastics, packaging, foodservice, and medical applications. Due to the flexibility of design parameters, these heaters are can be developed to suit specific sizes and heat patterns as the application dictates. The platens can be supplied with a thickness as small as ½” with surface finishes that range from “as cast” to a ground finish. Other options include mounting holes or bosses, threaded holes, cast-in stud terminals, recessed terminal exits, or special machined patterns on the platen surface. Special termination options such as leadwire extensions, quick disconnect plugs, or terminal boxes can be adapted to platen designs. Although aluminum is the predominant material used in heated platens, bronze alloys can be used for applications, which require higher temperatures. In addition, cooling tubes can be added for liquid cooled temperature control.



bTeflon Coated Platen Heaters:

Various types of plating and coatings can be added to Durex platen heaters to increase the hardness of the working surface or comply with specifications required for the application. Teflon® coating can be applied for lower temperature applications that require wear resistance or chemical resistance. Electroless Nickel plating can be applied to add a durable finish for higher temperature applications. Anodized finishes can also be provided for increased hardness and improved surface quality. As with all engineered products, coatings must be selected carefully based on the individual application. Factors such as maximum operating temperature, handling of the working surface, and secondary cleaning operations must be considered before specifying a particular coating or process.
