Improvements introduced in the manufacturing processes of tubular heating elements, intended to be embedded in a mass of aluminum or the like

摘要

Adjustment method of the ends of the tubular heating elements, designed to be embedded in a mass of aluminum or the like, in order to obtain a correct positioning.To plug in the free ends (4) of a tubular Resistance calibrated Caps (1) (2), forming a Unified whole, obtaining an accurate Fit between the retainers and the means (7) that hold such Resistance (1) (6) within the mold during the Injection of the most To Aluminum (5),Preventing the perfect adjustment between the ferrule and retainers (2) (7) means the mass of the Aluminium pipe (5). Each Cap Calibration (2) has a circular Recess on its Bottom (3) forming an area of reduced thickness, which allows for Riveting, support to the tubular casing Caps the ends of the resistance. Manufacture of plates and Pots.
