Selecting A Heater For Your Molding Application

It’s imperative to select the appropriate heater for a molding application if the performance is to be a success. For use in molding applications, strip heaters, cartridges, and tubular are the most common heating components.

Selecting the right heater for a molding application entails considering both the physical demands and heating requirements at hand. In thinking about heat demands, know what temperature needs to be reached; how rapidly that temperature is attained; and potential heat reduction resources through conduction, convection, and radiation. In looking at physical requirements, know the physical space the heater must fit, any insulation adjustments in the fit, and any extra space required for junction boxes and lead discontinuations.

Setting up A Heater

After choosing the heater, lead terminations, condensation, ground links, temperature level control, protection, and availability should be considered. Deal with each element before starting the setup process.

Thermocouples And Temperature Control Factor

Consistent part production is guaranteed by proper temp control. Think about essential characteristics and features in selecting the perfect temperature control. Processing conditions may be checked via a range of diagnostic features that are present in the most up-to-date design controls. These diagnostic features consist of the location of thermocouples, optimization of amperage to the norm of 15-30 amps, and evaluation of control zones. Achieving basic control of the mold temperature could be as simple as attaching thermocouples to an exposed surface after inserting them into the mold. Integrated thermocouples are features in certain types of heaters. Internally positioned thermocouples in cylinder heaters have several potential positions with the length of the heater. Most types of cartridge heater thermocouples and positions are either along the size of the heater and grounded to the sheath, bottom grounded by the end disc opposite leads, or center-positioned for relative heat level noticing.

Lead Wire Networks Factor

Magnetic field strengths and heat tend to get created when currents circulate via lead wires. Pushing those wires together isn’t advisable, which is why it’s always a good method to large-scale wire channels by 50% when possible. To prevent damage, it’s also an excellent method to split wires into different ways and cover all external wire channels. Leave enough space to not strain for joint box connections, and never force bends in lead exits. Prevent assembly peeling of insulation by rounding edges. Avoid joint box connection confusion by tagging all wires.
