Dry sand EPC sand processing equipment: sand processing equipment and resin bonded sand equipment crusher similar to remove the resin sand line, recycling machine, coupled with a screening machine can be used to disappear to die old sand processing. The main emphasis of resin bonded sand equipment is the regeneration effect, disappear-mode device is a cooling effect.
Lost foam shape using dry sand molding, unlike resin sand need to add the resin and other chemicals.
Lost mold sand handling is generally as follows: screening, magnetic separation, cooling. To the dust removal equipment, hoist, sand bucket, and electrical control.
After casting after 1:*0 you can out of the box, down box sand temperature is relatively high, up to *5 Baidu, lost foam process requires sand temperature must be reduced to below *0 degrees, so the cooling effect of a direct impact on production efficiency. According to different situations, sand handling is generally multi-level cooling, spiral elevator instead of the normal elevator to the initial cooling, increased air separation equipment not only can dust can also conduct a preliminary cooling.
Screening equipment: vibrating conveyor screening machine (there are a variety of forms and models of different spatial layout can be used in different forms).
Magnetic separation equipment: through a magnetic separator, suspension magnetic separators.
Cooling equipment are: fluidized bed, spiral elevator (usually as the main cooling equipment for auxiliary equipment), water-cooled rollers (cooling drum outside rain water jet principle), the sand temperature regulator.
From the cooling effect of the fluidized bed and the water-cooled rollers better, comparing the two: the fluidized bed power consumption, noise, and accounted for in a small area, consumption is not a small amount; water-cooled drum power, low noise, large area water consumption.
Lost Foam Casting Process (EPC process) materials foam beads (EPS) foam molding a predetermined shape castings, buried in dry sand on the paint drying and compaction, vacuum casting of liquid metal cooled castings or crafts.
Lost the advantages of the casting process:
1 castings and high precision lost foam casting is a near margin, the precise shape of the new process, the process does not require modulo, parting surfaces, sand core, thus casting flash, burrs and taper angle, and reduced the size of the error due to the core portfolio.
Designed to be flexible for casting structural design provides sufficient degrees of freedom. Originally divided into several parts assembled structure can be cast by several foam mold piece glue. That previously required the processing of the formation of holes, holes without sand core directly to the casting out, a significant reduction in the cost of machining and core. By the combination of several mold piece can create the appearance of high complexity.
(3) non-traditional casting in sand core does not appear the traditional sand casting due to the size of the sand core is inaccurate or under the core location is not accurate cause casting uneven wall thickness.
Clean production sand, no chemical binders, the low temperature foam is completely harmless to the environment, its emissions of organic matter when pouring rarely, and the emission time, place focus on ease of centralized collection and treatment; lost foam casting dry sand shape, greatly reducing the workload of the casting shakeout, cleaning, greatly reducing noise and dust of the workshop, old sand recovery rate of up to *5%. Low labor intensity, light weight appearance; rain and sand dust can focus on the collection, dust, and less harmful to the health of workers.
Reduction of investment and production cost of sand recovery system can be greatly simplified, without the overhead of the chemical binder, long mold life, the loss is small than traditional casting mold; casting wall thickness decreases, you can save the cost of investment. The number of production workers to reduce the appearance and casting production can be automated, completely changed the traditional casting "bitter, dirty, tired," the image.
Lost Foam Casting the scope of application
1) the production of iron castings and steel castings more, while casting less.
2) the main bulk of many varieties of mass-produced hundreds of pieces / year to several thousand / year. (Such as pipe fittings and valves)
3) from the simple, such as ductile iron, heat grate panels to complex progressive, exhaust pipes, a wide range of cylinder block, cylinder head, gearbox, break through th
