Mould is widely used in the machinery industry, usually on the use efficiency is extremely high, the heating rod as key components, quality, performance is stable or not, the relationship between major. Mould heating industrial pipe used throughout the heating pipe sales ratio has accounted for about 30% of the seats. Facing the huge market demand, will appear a variety of problems, the main problem is how to correctly treat mold heating tube damage problem occurred in the use of the process, this is not only feasible to user, the direct economic and credit problems among the producers. It is necessary to sort out and analyze the normal heating tube mould several reasons easily damaged, strengthening the introduction of ring.
Easily through the analysis of mould heating rod technician of the cause of the damage is mainly in the following areas caused by (for reference only).
1, die diameter and Die single head heating rod adaptation. Single head heating tube during use, because of its rapid heating cooling condition is poor, often cause body charred, oxidation, deformation heating external stainless steel tube, resulting in internal heating element – Electrothermal alloy wire (NI80Cr20) because of the high temperature air burning fuse, resulting in shortened life of single head electric heat pipe itself, so the single head electric excellent tube not only the production of good quality, more requirements of material and processing mould (aperture and aperture diameter of the closer the better), suitable aperture besides convenient for single head electric heat pipe, but also conducive to the conduction of heat between the two, thus prolonging the service life of electric heating pipe heating pipe itself.
Whether to consider the motion of 2 work environment, heating pipe design. Before the single head heating tube mould design and production, we also need to consider the motion of working environment, if the vibration is relatively large, we in the heating pipe heating wire requires the use of nichrome wire.
3, temperature control. When the mould single head heating tube work, the temperature control is also very important, when the temperature can not control, will also lead to external stainless steel heating tube, black oxide, deformation, resulting in internal heating element and the electrothermal alloy wire for high-temperature air burning fuse, resulting in shortened life of single head electric heat pipe itself. The general control in between 200-300 ℃.
The above is what we in the custom design of die and mold using several process red note, in order to prolong die service life of heating pipe. In fact, the life has a lot of work environment factors and so on. At the heating tube mould of easily damaged several problems can be useful to everyone, if the tube products, heating in the electric heating pipe products, network products need to have more accurate advice.
