1. Introduction to molding cartridge heater
The cartridge heater of the mold is an electric heating tube that is installed by punching a mold or slotting. The more common embedded mold dry-burning single-head electric heating tubes are usually straight rods, with limit stops, right-angle bends, and so on.
2, molding cartridge heater application:
Molding cartridge heater is mainly used for bag making machine, edge banding machine, packaging machine, 3D printer, mold heating, sealing machine, etc.
3, the main technical parameters of the molding cartridge heater
1). Shell material: stainless steel 304, stainless steel 321, stainless steel 310S, Ingle 800, Ingle 840, etc.
2). Heating wire material: 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, Cr20Ni80, etc.
3). Insulation filler: medium temperature insulating magnesium oxide powder, high temperature insulating magnesium oxide powder, etc.
4). High temperature lead: Silicone high temperature lead, mica high temperature lead, silica glass fiber tinned copper wire, mica glass fiber pure nickel wire, etc.
5). Rated voltage: 12V, 24V, 36V, 48V, 110V, 220V, 380V, etc.
6). Power (surface load): The power is determined according to the surface load and size. The general surface load is: domestic process: 5W/cm2; imported process grade A: 5W-12W/cm2; imported process AA grade: 12W-15W/ Cm2 ; Imported process AAA grade: 15W-20W/cm2;
7). Pipe diameter: 1mm-35mm
8). Length: according to customer requirements
9). Cold insulation resistance: the cold insulation resistance should be no less than 50MΩ at the factory inspection; after the seal test, the insulation resistance after long-term storage or use should be no less than 1MΩ
10). Cold leakage current: ≤ 0.5 mA
11). Cold insulation: 1600v. 1/seg
4, molding cartridge heater product advantage
1). Non-standard custom, flexible production, to meet the heating requirements of various equipment.
2). Working temperature can be as high as 760 °C (imported AAA embedded mold dry burning single-head electric heating tube)
3). Maximum surface load can be as high as 20-25W/cm2
4). The smallest diameter can be made 1mm
5). Built-in K-type or J-type thermocouple and detection temperature
6). Flexible mounting flange
7). Our products have obtained CE certification and are exported to various countries.
5, molding cartridge heating pipe installation diagram or precautions
For the cartridge heater of the mold, the most important thing is to ensure that the heat of the electric heating tube can be transferred to the heating medium in time, and the temperature of the material inside the single-head electric heating tube is reduced, so that the single-head electric power can be effectively improved. The life of the heating tube. We should pay attention to the following points during use:
1) The gap between the outer diameter of the right-angled cartridge heater and its insertion aperture should be minimized, usually the gap between the two is less than 0.2mm;
2) The mounting hole should be able to fit the cartridge heater of the mold, and the deviation tolerance should be controlled within 0.05mm. If the deviation is too large, the machining hole needs to be corrected;
3) Before the installation of the cartridge heater of the mold, the impurities left in the mold hole should be cleaned, such as organic oil and other residues, which will be carbonized after heating, thus affecting the heat conduction ability.
6, the molding cartridge heater wiring instructions
Root pipe connected to the power supply: directly according to the voltage size of the wiring, usually 220V, a fire line, a zero line; 380V, if there are only 2 binding posts, then it is connected to 2 fire lines.
Multiple pipes are connected to the power supply: they can be taken according to the actual situation: parallel, series, delta connection or Y-connection. If you don't understand anything, you can consult our sales customer service.
