The life of the single-head heating tube of the mold depends on the customer's operation and use environment on the one hand, and on the other hand, it depends on the manufacturing process of the manufacturer. Therefore, the single-head heating tube that can work on the equipment for a long time without being easy to break has always been the pursuit of customers. For our manufacturers, with the increase of new customers and the stability of old customers, the product quality must meet their requirements. To customize a good single-head heating tube product, we not only need to know the technical parameters of the single-head heating tube, but also know what details in the manufacturing process require more attention and discussion?
1. The closeness of the die hole diameter and the die single-head heating tube.
During the use of the single-head heating tube, due to its rapid heating and poor heat dissipation conditions, the external stainless steel tube body of the electric heating is often burnt, oxidized and deformed, which causes the internal heating element-the electric heating alloy wire to melt due to high temperature and air burning, resulting in the single-head electric heating tube The service life is shortened, so an excellent single-head heating tube not only requires good production quality, but also requires the material and processing aperture of the mold (the closer the aperture and the tube diameter are, the better, and the aperture error should be controlled between 0.05mm-0.1mm) and suitable aperture In addition to facilitating the replacement of the single-head heating tube, the outer diameter of the heating tube and the die diameter are also required to be closely integrated, which is beneficial to the heat transfer between the two, thus prolonging the heating life of the heating tube itself.
2. Control of working temperature.
When the single-head heating tube of the mold is working, the temperature control is also very important. The power of the heating tube must be within the range of the heating tube. Once the working temperature cannot be controlled, the stainless steel tube outside the heating tube will burn black. , Oxidation and deformation, which causes the internal heating element-electric heating alloy wire to melt due to high temperature air burning, which shortens the life of the single-head heating tube itself. It is generally controlled between 200-300°C.
3. Whether to consider the vibration of the working environment when designing the heating pipe.
Before the design and production of the mold single-head heating tube, we also need to consider the vibration in the working environment. If the vibration is relatively large, the heating wire in our heating tube needs to use nickel-chromium wire.
Through the above discussion of the three details that need to be considered and paid attention to in the production of the mold single-head heating tube, only by focusing on every detail of the single-head heating tube can a better single-head heating tube be produced for customers to use on the equipment.
