We supply band heaters specially produced for machines utilized in processing plastics. Band heaters for nozzles may be standard or with braized cap: Band Heaters are produced in a similar manner as band heaters but with specific charges as high as 6 W/cm2. These come in different diameters and lengths, in accordance with the form of application, and will 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, like 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 really a high end heater. Its performance and name are derived from Watlow’s exclusive mineral insulation-a material that includes a greater thermal conductivity compared to the mica and hard ceramic insulators found in conventional heaters.
A thin layer from the “high” thermal conductive MI material is used to electrically insulate the element wire from the 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 a lot 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. Many different heater constructions can be found, with a lot of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are made out of brass & Stainless-steel sheath .These nozzle band heaters are often employed if you have a limited space across the nozzle. An outstanding 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 utilized to equip nozzles of injection molding machines in the plastics processing industry. They may be plastics-proof and safeguard the proper temperature in the decisive place.
The brand new aluminum nozzle band heaters DAK guarantee an optimal heat progression. Furthermore, 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-steel) are utilized in combination with nozzles of injection molding machines within the plastics processing industry. These are plastic-tight and safeguard the temperature at the crucial point. The nozzle band heaters DG and DGS are suitable for general cylindrical heating tasks and therefore are well proven as an original accessory in a multitude of machine types customary in trade.
Heat transfer is founded on conduction as well as on radiation principle, which not only improves the thermal efficiency but very easy to assemble on nozzles as no pressure on heating surface is essential. Even padxud operator can fit the heater with no probability of failure in the heater.
Coil Type Nozzle Heaters are engineered to prevent the failures of heaters up 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 actually a high end heater. Its performance and name are derived from Watlow’s exclusive Thermocoupler mineral insulation-a material which has a higher thermal conductivity compared to mica and hard ceramic insulators found in conventional heaters.
We offer a complete collection of nozzle band heaters for that plastics industry as well as slip-on heaters for that medical and analytical industries. While every heater has a unique list of capabilities, each nozzle band heater was created to meet specific application requirements. Whether a software requires high performance, high temperature or high watt density we have the heater to fit the application.
