We supply band heaters specially developed for machines found in processing plastics. Band heaters for nozzles are generally standard or with braized cap: Heater Bands are made in the same way as band heaters however with specific charges of up to 6 W/cm2. These come in different diameters and lengths, based on the type of application, and will be fitted to thermocouples. The standard length of the power wire is one thousand mm.
The conventional 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 mostly employed for heating nozzles in injection presses. The mineral insulated band is a good performance heater. Its performance and name are based on Watlow’s exclusive mineral insulation-a material which has a much higher thermal conductivity compared to mica and hard ceramic insulators used in conventional heaters.
A thin layer in the “high” thermal conductive MI material is utilized to electrically insulate the element wire from the inside diameter from the heater sheath. A thicker, “low” thermal conductivity layer backs 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 within the plastics industry. Mica band heaters are capable of sheath temperatures approximately 1200°F (650°C) with stainless steel sheath, or 900°F (480°C) with aluminized steel sheath. A number of heater constructions can be found, with many termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. They are mechanically sturdy. These heaters are made from brass & Stainless sheath .These nozzle band heaters are generally employed when there is a small space around the nozzle. An outstanding coupling between the heating element & the nozzle supplies 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 inside the plastics processing industry. They may be plastics-proof and safeguard the correct temperature on the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. Furthermore, they excel through their high level of stability under temperature loads as much as 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless-steel) are utilized together 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 suitable for general cylindrical heating tasks and are well proven being an original accessory in a great number 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 with no probability of failure from the heater.
Coil Type Nozzle Heaters are specially designed to avoid 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 good performance heater. Its performance and name are derived from Watlow’s exclusive Temperature Controller mineral insulation-a material that includes a much higher thermal conductivity compared to the mica and hard ceramic insulators found in conventional heaters.
We provide you with a full type of nozzle band heaters for your plastics industry as well as slip-on heaters for that medical and analytical industries. While every heater includes a unique set 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 have the heater to suit the applying.
