Abstract
An electrically-heated wax spatula apparatus for use in molding and preparing wax models for investment casting in the field of dental prostheses and the field of metal work based on casting, and more particularly a wax spatula apparatus wherein the temperature of its spatula portion for wax-molding work can be adjusted immediately during use. The wax spatula apparatus comprises a spatula body, which is provided with a heating portion accommodating an electric heating element and a temperature sensor at the front end of the grip portion thereof and a wax-molding spatula portion installed in the heating portion, and a temperature controller for controlling the temperature of the spatula portion depending on a temperature signal from said temperature sensor of said heating portion, wherein the temperature controller comprises temperature-setting means capable of independently setting the temperature of the spatula portion at a plurality of temperature levels, and preset temperature selection means for selecting the preset temperature levels determined by said temperature-setting means, and the temperature-setting means is a temperature-setting switch disposed at the front end of the grip portion so as to be operable with a fingertip, whereby the temperature of the spatula portion is changed and adjusted immediately by operating the temperature-setting switch with a fingertip during wax-molding work.
