We supply band heaters specially produced for machines utilized in processing plastics. Band heaters for nozzles are generally standard or with braized cap: The Heaters Band are created in the same way as band heaters though with specific charges as high as 6 W/cm2. These come in different diameters and lengths, based on the kind of application, and may be fitted to thermocouples. The standard length of the power wire is 1,000 mm.
The typical 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 mostly employed for heating nozzles in injection presses. The mineral insulated band is actually a high performance heater. Its performance and name are derived from Watlow’s exclusive mineral insulation-a material which has a greater thermal conductivity than the mica and hard ceramic insulators utilized in conventional heaters.
A thin layer of the “high” thermal conductive MI material is utilized to electrically insulate the element wire through the inside diameter of the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire, directing the heat 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 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. Many different heater constructions can be found, with many termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are constructed from brass & Stainless sheath .These nozzle band heaters are generally employed should there be a limited space around the nozzle. A great coupling in between the heating element & the nozzle provides the maximum heating efficiency. These heaters are fitted for the nozzles of injection molding machines.
Nozzle band heaters are used to equip nozzles of injection molding machines in the plastics processing industry. These are plastics-proof and safeguard the correct temperature at the decisive place.
The brand new aluminum nozzle band heaters DAK guarantee an optimal heat progression. Additionally, they excel through their high level of stability under temperature loads as high as 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless) are used in conjunction 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 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 only increases 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 chance of failure from the heater.
Coil Type Nozzle Heaters are engineered to stop 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 a high end 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 utilized in conventional heaters.
We provide you with an entire collection of nozzle band heaters for that plastics industry in addition to slip-on heaters for your medical and analytical industries. While every heater features a unique group of capabilities, each nozzle band heater is designed to meet specific application requirements. Whether a software requires high end, high temperature or high watt density we have now the heater to fit the application form.
