The misunderstanding of pulse press is more expensive than constant temperature press

The misunderstanding of pulse press is more expensive than constant temperature press

At present, there are two types of press setters on the market: the press setter with pulse heating mode is called pulse press setter; The press with constant temperature heating is called constant temperature press.

Many people think that the pulse press is more expensive than the constant temperature press, and the pulse press is better than the constant temperature press. In fact, this is just a misunderstanding. To get out of this misunderstanding, we have to start from the composition of the press.

Generally, a press setter consists of the following parts: (1) press head heating mechanism, (2) camera focusing mechanism, (3) camera and lens, (4) press head movement mechanism, (5) press head temperature control unit, (6) liquid crystal glass fixing mechanism, (7) mobile phone wiring fixing mechanism, (8) silicone tape mechanism, (9) motion controller, (10) display, etc.

Among the components mentioned above, there are two ways to heat the indenter: pulse heating and constant temperature heating. In terms of production cost, pulse heating is more expensive than constant temperature heating. In terms of use, pulse heating is faster than constant temperature heating in heating and cooling, which is the advantage of pulse. But the actual situation is that the pressure head used for pulse is thin, the temperature error is large, the temperature is not easy to control, and the pressed wire is easy to rebound. Constant temperature is a relatively mature technology, with high precision of controllable temperature and relatively high yield of pressed wire.

Therefore, if the heating mode of a press is different from that of the heating mechanism of the press head, and the above (2) to (10) are the same, then the pulse press is more expensive than the constant temperature press. However, the fact is just the opposite. In order to maximize profits, many manufacturers use pulse parts for the press head, Other mechanisms (2) to (10) use some poor components, and even omit some mechanisms. Most of the work can only be done manually by the user, such as manual focusing, manual alignment, manual rolling of silicone rubber, etc. The reason why the constant temperature press is now more expensive than pulse, such as the constant temperature press produced by Shenzhen Hailisi, in addition to the low cost of constant temperature heating, other mechanisms use better materials or add some auxiliary mechanisms that can improve the degree of automation, and also solve the problem of rapid cooling of the pressure head, so it will be expensive, but it is more convenient to use.
