SAND CASTING EQUIPMENT.

1.Jolt-squeezing moulding machines solutions to common problems
1.1 Air filter gas blocking cold, due to the vacuum pump work process to produce some water, a long time plus some foreign matter in the pipeline will be air filter gas in the filter element blocked, the pressure gauge at this time look at the pressure is not small, but the air flow is not enough, resulting in the machine shock powerless.

1.2 between the piston and the pump iron is not lubricated, rust, can also be caused by the shock powerless, to solve this problem, you can open the rubber tube to the shock table, inject a pound of kerosene or gasoline, and then on the good, start the machine shock, then the sound of shock will have a very obvious change.

1.3 Due to the long time vibration, the 6 M20 hexagonal nails that connect the shocking table and the shocking piston are loose, so that there is a gap between the shocking table and the piston, and the working airflow leaks from here, causing the shocking forceless, especially after the compaction can not shocking. Mostly this is the reason. Operation valve in the unfamiliar time, must not move in reverse, because some stations have two or three tubes, so as not to cause machine action errors. Moulding machine in the work, the manipulation valve each move a station, to wait for the machine action to complete in place, and then move the next station, because the machine action is different fast and slow, it is easy to cause machine errors.

2. Advantages of green sand casting
2.1 Wet sand molding method, suitable for most metal materials, mass production of molding method, clay wet sand molding is the most economical molding method. Foundry plants equipped with the latest technology control devices should gradually achieve, with wet sand control technology can repeatedly get the best performance. These control devices include, sieve separation of metal, reuse sand cooling, reuse sand mixing accurate release of additives, etc.

2.2 Green sand recycling cost is low, more than 95% of the old sand can be reused, with Foundry Machinery, Sand Preparation Systems constantly updated, the old sand recycling rate and old sand performance has been improved, GS high efficiency rotator mixer to improve the mixing degree of green sand, so that the green sand in the coal powder bentonite, moisture content can maintain a stable balance, so the quality of green sand can maintain high quality, removable flask molding machine is widely used, so that the green sand sand sand compactness, air permeability, so that the quality of green sand can maintain high quality. The GS high efficiency rotator mixer improves the mixing of green sand, so that the coal dust bentonite and moisture content in green sand can maintain a stable balance, so the quality of green sand can maintain high quality, removable flask molding machine is widely used, so that the tightness of green sand sand, air permeability and other properties are improved, the advantages of green sand casting more obvious, so unless it is large castings or non-ferrous metal castings using precision Therefore, unless it is a large casting or non-ferrous metal casting using precision casting (resin laminated sand casting or lost wax method molten sand casting).
