Second, the cutter is used to cut the product into as many grams as possible. The dispenser works at the same time. The copper mold is fixed on the dispensing machine. First, the outermost layer is colored. Dispensing machine has its own positioning. If there is any area beyond the fixed point after baking, it will be removed manually immediately. The missing parts are shaded manually.
 
Finally, the slice is put into the mold and heated in the vulcanizer for extrusion. After being squeezed, the silica gel will fill the mold and exhaust the air. If the air cannot be discharged, the bubbles on the product surface will become defective products. Workers trim the products on the product inspection table, tear off the redundant parts, and use a blade or grinder to level the uneven parts. The quality inspectors check the quality one by one and pick out the defective products.
