Tubular Heaters Keep Heat On To Get The Lead Out Problem: Almost all metal objects have to be heated up at one time or another in the manufacturing process. This applies to the lead plates used in your car's DC battery. One manufacturer of a machine that molds these plates uses several tubular heaters in their equipment. This machine is found exclusively in battery manufacturing facilities. Lead has a melting point of around 340°C (650°F), so the tubulars have to keep the process above this temperature. The lead is initially heated by means other than electric tubulars, then is kept warm in a pipe by tubulars elements until it reaches the mold which is heated by FIREROD® cartridge heaters. Grooves in the pipe are used for mounting the tubulars heaters. This machine is very expensive, and d
