We supply band heaters specially developed for machines found in processing plastics. Band heaters for nozzles are generally standard or with braized cap: Custom The Band are made in the same way as band heaters however with specific charges as high as 6 W/cm2. These come in different diameters and lengths, according to the type of application, and can be fitted to thermocouples. The standard length of the power wire is 1,000 mm.
The standard model (with Alusi band) is suitable for applications where space is limited, as in moulds and hot chambers. Band heaters with braized cap in TIG welded stainless steel are mainly used for heating nozzles in injection presses. The mineral insulated band is really a high end heater. Its performance and name are produced from Watlow’s exclusive mineral insulation-a material which has a greater thermal conductivity than the mica and hard ceramic insulators found in conventional heaters.
A thin layer from the “high” thermal conductive MI material is utilized to electrically insulate the element wire from the inside diameter in 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 used in applications across various industries, and extensively inside 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. Many different heater constructions are available, 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 made from brass & Stainless sheath .These nozzle band heaters are often employed if you have a limited space across the nozzle. An outstanding coupling in between the heating element & the nozzle supplies the maximum heating efficiency. These heaters are fitted towards the nozzles of injection molding machines.
Nozzle band heaters are used to equip nozzles of injection molding machines inside the plastics processing industry. They may be plastics-proof and safeguard the appropriate temperature at the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. In addition, they excel through their high degree of stability under temperature loads as much as 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless steel) are used together with nozzles of injection molding machines inside the plastics processing industry. These are plastic-tight and safeguard the temperature in the crucial point. The nozzle band heaters DG and DGS are right 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 founded on conduction along with on radiation principle, which not only enhances the thermal efficiency but very easy to assemble on nozzles as no pressure on heating surface is vital. Even padxud operator can fit the heater without probability of failure in the heater.
Coil Type Nozzle Heaters were created to avoid the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can fulfill the higher temperature requirement prior to moulding at nozzle position
The mineral insulated band is really a high end heater. Its performance and name are produced from Watlow’s exclusive Thermocouple Sensors mineral insulation-a material which has a much higher thermal conductivity compared to the mica and hard ceramic insulators used in conventional heaters.
We offer a complete line of nozzle band heaters for the plastics industry in addition to slip-on heaters for your medical and analytical industries. While every heater includes a unique set of capabilities, each nozzle band heater was created to meet specific application requirements. Whether a software requires high end, high temperature or high watt density we now have the heater to match the applying.
