We supply band heaters specially developed for machines utilized in processing plastics. Band heaters for nozzles may be standard or with braized cap: Mica Heaters are created in a similar manner as band heaters however with specific charges of up to 6 W/cm2. They come in different diameters and lengths, based on the type of application, and will be fitted to thermocouples. The typical length of the power wire is one thousand mm.
The standard model (with Alusi band) would work for applications where space is limited, like 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 produced from Watlow’s exclusive mineral insulation-a material which has a higher thermal conductivity compared to 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 through the inside diameter in the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire, directing the heat inward toward the part being heated. The end 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 up to 1200°F (650°C) with stainless-steel sheath, or 900°F (480°C) with aluminized steel sheath. Many different heater constructions are available, with a lot of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. They are mechanically sturdy. These heaters are made out of brass & Stainless sheath .These nozzle band heaters are often employed if you have a small space across the nozzle. An excellent coupling between 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 utilized to equip nozzles of injection molding machines in the plastics processing industry. They are plastics-proof and safeguard the correct temperature in the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. Additionally, they excel through their high level of stability under temperature loads of up to 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless) are employed in conjunction with nozzles of injection molding machines inside 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 being an original accessory in a great number of machine types customary in trade.
Heat transfer is dependant on conduction as well as on radiation principle, which not just enhances 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 in the heater.
Coil Type Nozzle Heaters are engineered to avoid the failures of heaters up against the leakage and contamination of plastic material at nozzle position. This heater can meet the higher temperature requirement just before 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 includes a greater thermal conductivity compared to the mica and hard ceramic insulators found in conventional heaters.
We provide you with a complete type of nozzle band heaters for that plastics industry in addition to slip-on heaters for your medical and analytical industries. While every heater includes a unique group of capabilities, each nozzle band heater is made to meet specific application requirements. Whether an application requires high performance, high temperature or high watt density we have now the heater to suit the application form.
