They can also be used in plastic extruders, oil recovery systems and waste tanks. These are just a few of the many applications of these surface heaters. It’s important to work with a professional who can help you figure out which heater is the best option to meet your needs. This way, you can maximize the value of your investment while taking care of all Mica Band Heater Manufacturer your heating needs. Energy-saving belt heaters have an additional metal jacket with ceramic fiber insulation inside, wrapped around the heater to stop heat loss from the outer surface of the heater. Depending on the voltage and power, a suitable size of the resistance cable is selected according to the recommendation of the resistance cable manufacturer.
Liquid plastic, hydraulic oil and moisture are three main causes of premature contamination errors. Of course, keeping heaters free of contaminants will reduce failure and replacement rates. Alternatively, a belt heater can be used that resists contamination. Problems with belt heating and the resulting downtime should be kept to a minimum when maintenance and engineering personnel have to meet all other requirements of their time. At the same time, market forces are driving injection molders to deliver products on time and error-free, other factors that require smooth operation of the belt heater.
We make sure the inner surface is smooth and consistent in shape to avoid hot spots or poor fit. Belt heaters are made to order as they vary in size and performance. The area from which heaters are used is often exposed to liquids, and therefore the wires can be completed with a protective cable.
Mica belt heaters are ideal for all types of plastics processing equipment. Mica tape heaters are made of high-quality mica and have resistance to nickel chrome. It is coated with a metal coating and can be rolled to the desired shape.
If the length of the cavity is 130 mm, five cooling channels would be required to ensure the necessary heat dissipation. In the mold, no work is done in relation to all the heat absorbed during the cooling of the melt from 190 ° C to 40 ° C. There are currently around 50 licensees operating 260 machines in 10 countries. When it’s time to replace or renew the tool, lightweight weighing designs should be ready to be implemented into the new tool. In the cycle time of 7 s, 1 g of reduced resin saves more than 500 g of resin per hour and cavity.
