We supply band heaters specially developed for machines used in processing plastics. Band heaters for nozzles are either standard or with braized cap: Mica Band Heaters are produced in the same manner as band heaters though with specific charges as much as 6 W/cm2. They are available in different diameters and lengths, based on the form of application, and can be fitted to thermocouples. The typical length of the power wire is 1,000 mm.
The standard model (with Alusi band) is suitable for applications where space is restricted, as with moulds and hot chambers. Band heaters with braized cap in TIG welded stainless-steel are mainly utilized for heating nozzles in injection presses. The mineral insulated band is really a good performance heater. Its performance and name are produced from Watlow’s exclusive mineral insulation-a material that includes a higher thermal conductivity than the mica and hard ceramic insulators utilized in conventional heaters.
A thin layer of the “high” thermal conductive MI material can be used to electrically insulate the element wire from your inside diameter in the heater sheath. A thicker, “low” thermal conductivity layer backs the element wire, directing the warmth inward toward the part being heated. The result is a lot more efficient heat transfer … a performance solution that lowers element wire temperatures and increases heater life.
Mica band heaters are utilized in applications across various industries, and extensively in the plastics industry. Mica band heaters are designed for sheath temperatures approximately 1200°F (650°C) with stainless sheath, or 900°F (480°C) with aluminized steel sheath. A number of heater constructions can be purchased, with many termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are constructed from brass & Stainless-steel sheath .These nozzle band heaters are generally employed should there be a small space across the nozzle. An excellent coupling between the heating element & the nozzle provides the maximum heating efficiency. These heaters are fitted towards the nozzles of injection molding machines.
Nozzle band heaters are used to equip nozzles of injection molding machines inside the plastics processing industry. These are plastics-proof and safeguard the correct temperature at the decisive place.
The brand new aluminum nozzle band heaters DAK guarantee an optimal heat progression. Additionally, they excel through their high degree of stability under temperature loads of up to 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless steel) are used in combination with nozzles of injection molding machines within the plastics processing industry. They are plastic-tight and safeguard the temperature on the crucial point. The nozzle band heaters DG and DGS are appropriate for general cylindrical heating tasks and they are well proven being an original accessory in a multitude of machine types customary in trade.
Heat transfer is dependant on conduction in addition to on radiation principle, which not merely enhances the thermal efficiency but easy to assemble on nozzles as no pressure on heating surface is important. Even padxud operator can fit the heater with no risk of failure from the heater.
Coil Type Nozzle Heaters are specially designed to avoid the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can satisfy the higher temperature requirement prior to moulding at nozzle position
The mineral insulated band is actually a high performance heater. Its performance and name are derived from Watlow’s exclusive Cartridge Heater With Thermocouple mineral insulation-a material that has a higher thermal conductivity compared to the mica and hard ceramic insulators utilized in conventional heaters.
We provide you with a complete type of nozzle band heaters for the plastics industry in addition to slip-on heaters for your medical and analytical industries. While every heater has a unique group of capabilities, each nozzle band heater is designed to meet specific application requirements. Whether an application requires good performance, high temperature or high watt density we have now the heater to match the application form.
