We supply band heaters specially produced for machines utilized in processing plastics. Band heaters for nozzles are either standard or with braized cap: Mica Heater are created in a similar manner as band heaters but with specific charges of up to 6 W/cm2. These come in different diameters and lengths, in accordance with the form of application, and can be fitted to thermocouples. The standard length of the power wire is one thousand mm.
The standard model (with Alusi band) is suitable for applications where space has limitations, like moulds and hot chambers. Band heaters with braized cap in TIG welded stainless are mainly used for heating nozzles in injection presses. The mineral insulated band is really a good performance heater. Its performance and name are derived from Watlow’s exclusive mineral insulation-a material that includes a much higher thermal conductivity compared to mica and hard ceramic insulators utilized in conventional heaters.
A thin layer from the “high” thermal conductive MI material can be used to electrically insulate the element wire from the inside diameter in the heater sheath. A thicker, “low” thermal conductivity layer backs in 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 in the plastics industry. Mica band heaters are capable of sheath temperatures as much as 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 lots of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are constructed from brass & Stainless-steel sheath .These nozzle band heaters are often employed should there be a limited space around the nozzle. A great 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 utilized to equip nozzles of injection molding machines inside the plastics processing industry. They may be plastics-proof and safeguard the appropriate temperature in the decisive place.
The brand new aluminum nozzle band heaters DAK guarantee an optimal heat progression. In addition, they excel through their high degree of stability under temperature loads of up to 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless) are utilized in combination with nozzles of injection molding machines within the plastics processing industry. These are plastic-tight and safeguard the temperature on 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 large number of machine types customary in trade.
Heat transfer is based on conduction as well as on radiation principle, which not just enhances the thermal efficiency but easy to assemble on nozzles as no pressure on heating surface is vital. Even padxud operator can fit the heater without risk of failure of the heater.
Coil Type Nozzle Heaters are engineered to stop the failures of heaters from 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 really a good performance heater. Its performance and name are derived from Watlow’s exclusive Temperature Sensor Thermocouple mineral insulation-a material that includes a higher thermal conductivity compared to the mica and hard ceramic insulators used in conventional heaters.
We provide an entire line of nozzle band heaters for the plastics industry in addition to slip-on heaters for the medical and analytical industries. While every heater has a unique group of capabilities, each nozzle band heater is designed to meet specific application requirements. Whether a software requires good performance, high temperature or high watt density we have the heater to fit the application.
