Cast Heaters

An overmolded element is composed of a heating resistor of the shielded element type, embedded in an aluminum, cupro-aluminum (aluminum bronze) or brass alloy giving it excellent thermal conductivity and specially designed to operate under optimal exchange conditions.

Flat or circular in shape, the overmolded resistors are made according to your specifications, according to molding procedures ensuring perfect homogeneity of the material and therefore excellent thermal diffusion.

Flat or circular in shape, the overmolded resistors are made according to your specifications, according to molding procedures ensuring perfect homogeneity of the material and therefore excellent thermal diffusion.

The alloy is chosen according to the temperatures and conditions of use: aluminum for temperatures up to 400 ° C, brass and cupro-aluminum up to 650 ° C. These products can withstand significant mechanical stresses, such as the pressure of the heating plates when closing and locking the presses.

Technical characteristics

The overmolded armored elements are used in particular on the sleeves and dies of extruders, air or gas heaters, cooking plates, vaporization equipment, rolling mills, packaging lines, heating press plates. ..

The specific advantages of this technology have provided effective solutions for a number of applications:

  • An exceptional service life thanks in particular to the mechanical protection constituted by the alloy cast around the resistance.
  • The possibility of being machined and therefore of being able to be adapted to any type of surface to be heated.
  • High heating power density (8 W / cm²) and more homogeneous.
Product line

The overmolded resistors are made to measure , according to your specifications. Do not hesitate to consult us.

    • Shielded element defined by our design office, for its power and its shaping (shaping before going to the foundry).
    • Connection: by threaded terminals or clamp terminals. They can be protected by a remote cover , IP XX , protecting liquid and dust projections.
    • Overmolding alloy defined according to the conditions of use: cupro-aluminum , aluminum, brass. Other materials on request …..
    • When the overmoulds are half collars, they are held by straps fitted with compensated tightening (springs) exerting strong pressure to optimize contact.
    • Dimensional: consult us according to your needs. Some of our achievements: flat resistors with a diameter of 540 mm, half collars with a diameter of xx and height xx
    • Manufacture of unique pieces or small series .
  • Special finishes:
    • Drillings for inserting a temperature probe
    • In order to avoid thermal inertia problems, overmolded resistors can be fitted with a fluid or finned cooling circuit .
