Mandarin has a very important step in the quality inspection of cake/battery, which is to dissect the inner tube to weigh the effect powder.
Testing will be conducted on each cake product.
Sufficient effect powder is the guarantee of the product effect.
Mandarin's basic requirements for effect powder are: 0.8''-- 3.8-4 grams, 1''-- 6-7 grams, 1.2''-- about 11-12 grams.
If the factory produces according to the powder amount requirements, the material quality used is relatively good, and the fire rate is high, then the effect of the product will not be bad.
Since the amount of effect powder accounts for a relatively large part of the product cost, some factories will save costs by reducing the amount of powder.
Therefore, when purchasing fireworks, the purchaser should not only pay attention to the inner diameter of tube, but also pay attention to the effect powder of the product.
