5. In the low pressure die casting machine,before the baking mold, the ejector must be propped up, then use the baking gun to bake the mold to about 300 degrees, use the air gun to blow off the debris on the mold, start spraying, and put the matching paint on the coating. Inside the gun, align the mold 90 degrees vertically. After spraying, use a baking gun to heat it for 3-5 minutes with a small fire, then bake it to the mold casting temperature with a large fire (according to the standard of operation).

Start casting, adjust the process parameters before casting, check whether the air pressure meets the requirements, and use air gun to blow out the impurities in the mold (from the inside to the outside) to cast the first product, do not place the filter. The holding time is 60 seconds and the cooling time is 200 seconds. The second product should be placed in the filter. When the filter is placed, it is not allowed to be deflected. It must be placed at the bottom of the riser. The parameters are cast in accordance with the casting standard book.
