Since the introduction of insulating compounds several years ago there has been great development in this branch of the industry and an extraordinary increase in the use of molded insulations. These insulating compounds are now prepared for special properties, of which mechanical strength and resistance to heat are specially important. The Hemming Manufacturing Company, Garfield, N. J., has devoted its entire energies to the development and production of heat-resisting molded insulating materials, with the result that its factory has in the last few years been increased from a floor space of 6,000 square feet to a present area of 40,000 square feet. The company makes its compounds under its own patented processes. The raw materials are carefully selected and tested and, after being properly compounded, are taken to the molding department, a view of which is shown above. A cold molding process is used in which the material is formed into the desired shapes in steel dies by means of hydraulic presses. After being pressed, the pieces are dired in ovens and finally polished or buffed in the finishing department. The company makes three kinds of insulating products, known as Gummon, Tegit and Hemit, which have slightly different properties. In the large variety of articles molded of these materials are included, socket, receptacle and plug bodies and parts, cutout and switch bases, covers and handles, third-rail insulators, arc separators and controller parts, bushings, barriers, etc.
