加热棒-加热管-电热管使用-寿命

加热棒-加热管电热管使用-寿命

模具在机械行业中广泛运用,通常对其使用效率要求极高,加热棒作为关键部件,质量、性能的稳定与否,关系重大。工业使用的模具加热管在整个电热管的销售比例中也占到30%左右的席位。面对着庞大的需求市场,就会出现各种各样的问题,主要问题还是如何正确的看待模具加热管在使用过程中发生损坏的问题,这个不但切实的关系到使用者,生产者之间直接的经济和信誉问题。有必要好好的整理和分析正常模具加热管容易损坏的几种原因,加强引进戒。

通过技术员的分析模具加热棒容易造成损坏的原因主要有以下几个方面所造成(仅供参考)。

1、模具孔孔径与模具单头加热棒的密合度。 单头电热管在使用期间,由于本身加热迅速散热条件差,常造成电热外部不锈钢管体焦黑、氧化、变形,因而造成内部发热元件-电热合金丝(NI80Cr20)因高温空烧融断,造成单头电热管本身寿命缩短,所以优良的单头电热管不但需要生产质量好,更要求模具的材质与加工孔径(孔径与管径越接近越好),适合的孔径除了方便换单头电热管之外,也有利于两者热能之间的传导,因而延长加热管本身电热管的使用寿命。

2、加热管设计时是否考虑工作环境的震动性。在模具单头加热管设计生产之前,我们还需要考虑工作环境下的震动性,倘若震动性比较大,我们加热管中的电热丝就需要采用镍铬丝。

3、工作温度的控制。在模具单头加热管工作的时候,温度的控制也是至关重要的,温度一旦控制不住,也会导致加热管外部不锈钢管体焦黑、氧化、变形,因而造成内部发热元件-电热合金丝因高温空烧融断,造成单头电热管本身寿命缩短。一般控制为在200-300℃之间。

以上就是我们在设计定制模具和模具使用过程红得需要注意的几点,以便延长模具加热管寿命。其实生活中还有很多工作环境因素等等。望此次模具加热管容易损坏几个问题的探讨能够对大家有用,若在电热管产品、加热管产品、网带产品等需要有更多更准确的咨询.欢迎来电咨询:0512-57123258

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.
