Once the glaze layer of crucible is damaged, it will lead to oxidation and aging of crucible easily in the process of use. The crucible should be handled carefully in a padded cart (or other suitable conveyer). Our company use rope, rubber, moisture-proof plastic paper, shockproof to pack the crucible, and according to customers' needs, we can customize wooden cases, export packaging cartons, paper tubes, etc., to ensure that the crucible wouldn't be damaged in transit. Method of Crucible Storage The crucible should be protected from moisture. The warehouse for storing crucibles should be dry and ventilated, and the temperature should be kept between 5ºC~25ºC, and the relative humidity should be 50-60%. The crucible must not be stored on brick soil or cement floor to avoid moisture. Company Profile Qingdao TTWY Manufacturing Co.,Ltd is a company specialized in producing casting equipment.
