We supply band heaters specially developed for machines found in processing plastics. Band heaters for nozzles may be standard or with braized cap: Band Heater are made in the same manner as band heaters however with specific charges as much as 6 W/cm2. These come in different diameters and lengths, according to the form of application, and can be fitted to thermocouples. The typical length of the power wire is 1,000 mm.
The typical 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 a high end heater. Its performance and name are produced from Watlow’s exclusive mineral insulation-a material that has a greater thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
A thin layer in the “high” thermal conductive MI material is used to electrically insulate the element wire from the inside diameter from the heater sheath. A thicker, “low” thermal conductivity layer backs in the element wire, directing the warmth inward toward the part being heated. The end result is much 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 inside the plastics industry. Mica band heaters are capable of sheath temperatures up to 1200°F (650°C) with stainless steel sheath, or 900°F (480°C) with aluminized steel sheath. A number of heater constructions are available, with lots of termination and clamping options.
Nozzle band heater3are basically a mica insulated band heater. They are mechanically sturdy. These heaters are made from brass & Stainless-steel sheath .These nozzle band heaters are generally employed if you have a limited space across the nozzle. An outstanding coupling involving 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 within the plastics processing industry. These are plastics-proof and safeguard the correct temperature in the decisive place.
The newest aluminum nozzle band heaters DAK guarantee an optimal heat progression. Furthermore, they excel through their high amount of stability under temperature loads as high as 450°C.
The nozzle band heaters DG (of brass) and DGS (of stainless) are used together with nozzles of injection molding machines in the plastics processing industry. They are plastic-tight and safeguard the temperature in the crucial point. The nozzle band heaters DG and DGS are appropriate for general cylindrical heating tasks and therefore are well proven as being 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 merely 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 without chance of failure from the heater.
Coil Type Nozzle Heaters are specially designed to prevent the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can fulfill the higher temperature requirement just 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 Sensor Thermocouple mineral insulation-a material that includes a higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
We offer a complete line of nozzle band heaters for your plastics industry along with slip-on heaters for your medical and analytical industries. While every heater features a unique set of capabilities, each nozzle band heater is designed to meet specific application requirements. Whether a software requires high performance, high temperature or high watt density we now have the heater to match the application form.
