Quality Control
YUFA always insist that all products can only be sold after passing the quality inspection. YUFA have its own professional quality inspection laboratory and quality inspection personnel. From the raw materials entering the factory, furnace smelting, preliminary finished products, crushing, to the final finished products leaving the factory, YUFA performs inspections according to the different dosages and combined with the company's matching inspection standards. The minimum number of inspections is 10 times, and the maximum can be more than 40 inspections.

Products out of factory should be inspected according to standards. If all items meet the technical requirements, the batch of products is qualified. During quality supervision and inspection, the inspected products are divided into different particle size ranges. Randomly select a particle size for sampling from them.
