In the process of using the cup baking machine, there will often be a mug burst when it is half baked, the burst position is not fixed, it is a crack thinner than hair, it is difficult to find if you do not look carefully, but the sound of the burst is very obvious, many friends may be quite strange, what is the reason?In fact, this situation is relatively common, generally due to the following reasons:
First, the room temperature is relatively low
Mainly occurs in winter or in this case is when the weather is cold, when indoor temperature or mark cup environment with low temperature, if we take out directly with the heated baking cup machine, when the temperature rises to a certain, because mark cup have a larger temperature difference between inside and outside wall, cracking phenomenon occurs,In this case, the location of the burst is not fixed, and the crack is relatively fine.
Solutions:Before using mugs for baking, we make sure the temperature of the mug is consistent and room temperature to (do not differ too much), so you can avoid this kind of circumstance happening, especially in winter, the temperature is lower, mark cup itself can not be directly used to heat, it is best to put in indoor hand or hot for a period of time, to ensure that the mark cup before baking temperature is too low.
Second, the mugs are relatively thin
There are many kinds of heat transfer printing mugs in China. Although all of them are ceramic, different manufacturers will produce mugs suitable for their own sales for different considerations. In this process, some companies will reduce the thickness of ceramic cups, resulting in thin inner and outer walls.When baking mugs, the pressure of baking coasters is too large, which leads to hot expansion of mugs and cracks on mugs' surfaces.
Solution: When choosing mugs, we should choose thick mugs as far as possible, which will lead to cost increase, but can ensure that there will be no defective products, and it is convenient for consumers to use.If the mug wall is thin, the heat transfer of the mug will be fast and it is not convenient to use.
Three, the pressure of the baking coaster is not uniform
Generally this kind of situation is relatively rare, but some of the domestic manufacturers in order to obtain a lower cost, thus in the sales link has price advantage, it was not too fastidious molds and production of the error of the baking cup mat, it will appear uneven pressure in the process of cooking, make the mark cup where the stress of the fracture, and at the same time can also affect the baked image clarity,Greatly increased defective rate.
Solution: this is still to choose when we choose, choose some powerful manufacturers, especially not simple price comparison, so as to avoid this situation.
To sum up, the reasons for the cracks in the baking process are basically the above points. What needs to be emphasized is that we must not blindly follow the low price when choosing, while ignoring the performance and various indicators of the equipment itself.
