Heater bands for injection molding play a vital role in injection molding machines. Injection molding machine heating bands are electrically heated devices, mainly used to heat the barrel and mold of the injection molding machine, and transfer heat to the steel through resistance heating to heat it up to meet the needs of industrial production. The stability and safety of the heating band make it an indispensable component in the injection molding machine.
The heater bands for injection molding machines work by resistance heating, using electric heating alloy wire or fuse wire as a heating element. When current passes through these elements, heat is generated to achieve the purpose of heating. This design makes the heating band safer and more stable, avoiding the loss and danger that may be caused by direct contact with the material.
Reasons for easy damage of injection molding machine heating bands
1. Lack of regular maintenance:
Heater bands for injection molding machines work at high temperatures for a long time. If it is not maintained and cleaned for a long time, dust, moisture and other impurities on the outside of the machine body will remain on the surface of the heating band, resulting in uneven heating, and carbon deposition inside the heating band, thereby shortening the life of the heating band.
2. Improper use:
During the use of the injection molding machine heating band, it is necessary to avoid the burning of objects such as cigarette butts and the collision of objects. At the same time, it is necessary to pay attention to the distance between the heating band and the parts to avoid damage to the parts due to excessive heating.
3. Aging or damage:
After the injection molding machine heating band is used for a long time, the heating element will be affected by thermal expansion and contraction, resulting in problems such as the heating wire breaking and loose contacts. At this time, the heating band needs to be replaced.
4. Insulating material problem:
The electric heating band usually uses insulating materials such as ceramics, mica, and magnesium powder. These materials have poor thermal conductivity, resulting in excessive heating wire temperature, accelerated oxidation, and shortened service life.
Solutions to the easy damage of the heating band for injection molding machine
1. Increase maintenance:
Frequently maintain and maintain the injection molding machine heating band, clean and replace the heating element in time to ensure that the heating band is in normal working condition and avoid problems such as uneven heating.
2. Optimize the use environment:
When using the injection molding machine heating band, try to avoid environmental conditions such as fireworks, rain and humidity. Avoid excessive use or excessive heating to cause damage to components.
3. Replace the heater bands for injection molding machines:
For the aging and damaged heating band of the injection molding machine, it is necessary to replace it in time to ensure the quality and working efficiency of the heating band.
In short, the heating band of the injection molding machine is an important part of the injection molding process. If it is used improperly and lacks maintenance, it is easy to be damaged. Therefore, special attention should be paid to the maintenance and use of the heater bands for injection molding machines to avoid losses in production.
