We supply band heaters specially developed for machines used in processing plastics. Band heaters for nozzles are generally standard or with braized cap: Heater Band are produced in the same way as band heaters but with specific charges as high as 6 W/cm2. They come in different diameters and lengths, in accordance with the form of application, and can be fitted to thermocouples. The conventional length of the power wire is 1,000 mm.
The standard model (with Alusi band) is acceptable for applications where space is restricted, like moulds and hot chambers. Band heaters with braized cap in TIG welded stainless-steel are mostly utilized for heating nozzles in injection presses. The mineral insulated band is a high end heater. Its performance and name are produced from Watlow’s exclusive mineral insulation-a material which has a much higher 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 the inside diameter from the heater sheath. A thicker, “low” thermal conductivity layer backs in the element wire, directing the heat inward toward the part being heated. The result is much 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 as much as 1200°F (650°C) with stainless steel sheath, or 900°F (480°C) with aluminized steel sheath. A number of heater constructions can be purchased, with a lot of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are generally mechanically sturdy. These heaters are constructed from brass & Stainless-steel sheath .These nozzle band heaters are generally employed should there be a small space round the nozzle. An excellent coupling in 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 utilized to equip nozzles of injection molding machines within the plastics processing industry. They are plastics-proof and safeguard the proper temperature at the decisive place.
The brand new aluminum nozzle band heaters DAK guarantee an optimal heat progression. Furthermore, they excel through their high amount of stability under temperature loads of up to 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless steel) are employed in conjunction with nozzles of injection molding machines within the plastics processing industry. They are plastic-tight and safeguard the temperature in the crucial point. The nozzle band heaters DG and DGS are appropriate for general cylindrical heating tasks and are well proven as being an original accessory in a multitude of machine types customary in trade.
Heat transfer is based on conduction along with 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 probability of failure from the heater.
Coil Type Nozzle Heaters are engineered to stop the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can meet the higher temperature requirement before moulding at nozzle position
The mineral insulated band is a high end heater. Its performance and name are based on Watlow’s exclusive Thermocouple mineral insulation-a material that includes a higher thermal conductivity compared to the mica and hard ceramic insulators found in conventional heaters.
We provide you with a complete line of nozzle band heaters for the plastics industry along with slip-on heaters for your medical and analytical industries. While every heater features a unique list of capabilities, each nozzle band heater is made to meet specific application requirements. Whether an application requires high end, high temperature or high watt density we now have the heater to fit the applying.
