Casting process because of its multi-machine production, lifting and transport capacity, the production process with high temperature, and produce a variety of harmful gases and dusts, fumes and noise characteristics, making the casting operation frequent burns, fire, explosion and mechanical injury and other accidents .

      Molding machine operations where workers should be noted carefully:

(1) hand shape and build core should be taken to avoid sand box, drop-box landing foot, fingers squeezing sand box, sand the nails and other sharp metal pieces pierced the hand, nail their feet and other injuries. In operation, pay attention to handling sand box, core box the way, put on sturdy shoes safety shoes with screening or magnetic separation of sand in the nails, metal fragments, etc.

         (2) The shape of lifting operations should pay attention to transportation safety, the absolute prohibition for convenience in lifting the bottom of things to work on the sand should be almost stable and sturdy bracket to prevent objects falling collision injuries.

(3) shape with a sand box stacking to prevent the collapse of injured people, the total stacking height of generally not more than 2m.

         (4) pound sand in the shape, the operator header to wear hard work shoes, and to maintain mental concentration, operating tamping machine, rams do not pound on the foot or side boxes, box tape, and the gate on the outlet, so as not to affect the quality of sand and cause injury.

(5) throwing sand molding, the operator should complement each other well; throwing sand around cantilevers machine and other items do not pile up the sand box; stop working, you should bear in weeks cantilever, it can not swim.

(6) the use of pit shape, to understand the shape of parts of the pit water level to prevent pouring hot liquid metal case tide when the explosion occurred, but also arranged the exhaust channel, so that the bottom of the mold type gas discharge outside smooth .

(7) core of iron, sand box ribs exposed to the mold surface, not otherwise, because it is hygroscopic, liquid metal in contact with it is easy to produce "soy fire" burns operators.

(8) the use of machine molding, core making, we must know the machine's performance and safety procedures
