We supply band heaters specially produced for machines utilized in processing plastics. Band heaters for nozzles are generally standard or with braized cap: Band Heater are made in the same way as band heaters but with specific charges of up to 6 W/cm2. They come in different diameters and lengths, based on the kind of application, and may be fitted to thermocouples. The conventional length of the power wire is 1,000 mm.
The conventional model (with Alusi band) is acceptable for applications where space is restricted, as in 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 a good performance heater. Its performance and name are derived from Watlow’s exclusive mineral insulation-a material which has a greater thermal conductivity compared to the mica and hard ceramic insulators used in conventional heaters.
A thin layer in the “high” thermal conductive MI material is used to electrically insulate the element wire from your inside diameter of the heater sheath. A thicker, “low” thermal conductivity layer backs the element wire, directing the warmth inward toward the part being heated. The effect is more efficient heat transfer … a performance solution that lowers element wire temperatures and increases heater life.
Mica band heaters are used in applications across various industries, and extensively in the plastics industry. Mica band heaters are capable of sheath temperatures approximately 1200°F (650°C) with stainless sheath, or 900°F (480°C) with aluminized steel sheath. A variety of heater constructions can be found, with lots of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are made from brass & Stainless sheath .These nozzle band heaters are generally employed if you have a restricted space across the nozzle. An excellent coupling in between the heating element & the nozzle provides the maximum heating efficiency. These heaters are fitted to the nozzles of injection molding machines.
Nozzle band heaters are used to equip nozzles of injection molding machines in the plastics processing industry. They may be plastics-proof and safeguard the proper temperature on the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. Furthermore, they excel through their high degree of stability under temperature loads as high as 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless) are used in conjunction 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 suitable for general cylindrical heating tasks and they are well proven as an original accessory in a great number of machine types customary in trade.
Heat transfer is based on conduction as well as on radiation principle, which not just improves the thermal efficiency but very easy to assemble on nozzles as no pressure on heating surface is important. Even padxud operator can fit the heater without any probability of failure from the heater.
Coil Type Nozzle Heaters were created to stop the failures of heaters up 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 a high performance heater. Its performance and name are derived from Watlow’s exclusive Temperature Sensor Thermocouple mineral insulation-a material that includes a much higher thermal conductivity compared to the mica and hard ceramic insulators utilized in conventional heaters.
We provide you with a complete line of nozzle band heaters for the plastics industry in addition to slip-on heaters for that medical and analytical industries. While every heater includes 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 now have the heater to suit the application form.
