We supply band heaters specially developed for machines utilized in processing plastics. Band heaters for nozzles are generally standard or with braized cap: Mica Band Heaters are made in the same way as band heaters but with specific charges as high as 6 W/cm2. They are available in different diameters and lengths, based on the kind of application, and will be fitted to thermocouples. The conventional length of the power wire is one thousand mm.
The conventional model (with Alusi band) is suitable for applications where space has limitations, as in moulds and hot chambers. Band heaters with braized cap in TIG welded stainless-steel are mainly employed for heating nozzles in injection presses. The mineral insulated band is a good performance heater. Its performance and name are produced from Watlow’s exclusive mineral insulation-a material which has a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
A thin layer from the “high” thermal conductive MI material can be used to electrically insulate the element wire from your inside diameter from the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire, directing the warmth inward toward the part being heated. The result is 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 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 generally mechanically sturdy. These heaters are made from brass & Stainless sheath .These nozzle band heaters are generally employed should there be a restricted space around the nozzle. A great coupling involving the heating element & the nozzle offers the maximum heating efficiency. These heaters are fitted for the nozzles of injection molding machines.
Nozzle band heaters are employed to equip nozzles of injection molding machines inside the plastics processing industry. They are plastics-proof and safeguard the appropriate temperature at the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. Additionally, 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 at the crucial point. The nozzle band heaters DG and DGS are appropriate for general cylindrical heating tasks and they are well proven as 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 just improves the thermal efficiency but simple to assemble on nozzles as no pressure on heating surface is vital. Even padxud operator can fit the heater without any chance of failure of 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 satisfy the higher temperature requirement before moulding at nozzle position
The mineral insulated band is really a high end heater. Its performance and name are produced from Watlow’s exclusive Temperature Sensor Thermocouple mineral insulation-a material that has a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
We provide you with a full type of nozzle band heaters for the plastics industry as well as slip-on heaters for your medical and analytical industries. While every heater features a unique set of capabilities, each nozzle band heater is made to meet specific application requirements. Whether an application requires good performance, high temperature or high watt density we have the heater to match the applying.
