Strain gauges are applied to the casting part at two positions and the sand core is drilled out by a drilling machine, see Fig. 7, to determine the shrinkage of the casting part onto the cast-in sand core. The releasing strains of the aluminium part due to the removed sand core are measured by a HBM QuantumX MX840B universal measuring amplifier.
Sand casting is a very versatile process and can produce castings of extreme complexity in a wide range of aluminium alloys. Interest in light weighting and improvements in the technology of sand casting has driven the average weight and size of aluminium sand castings upward, with many parts weighing over 50 kg and with some parts as large as 100 m 3.

sand casting processes are a limitation to this technique. • Many new casting processes have been developed which can take into consideration the aspects of dimensional accuracy and surface finish. Some of these processes are die casting process, investment casting process, vacuum-sealed moulding process, and shell moulding process.
9.3: The Drilling Process. Print. We have discussed the components of the drilling rig, now let's discuss the drilling process itself. An oil or gas well is drilled in a very ordered sequence. The steps in this sequence are almost universally applied to the drilling of all wells. Plan the Well: As we have discussed, exploration well prospects ...

Machines can be built with multiple wheels for automation. Automated systems include basket, table, spinner hangers and continuous conveyor processing. Wheel blast systems are a less expensive way to blast (due to higher media recycleability and automation) than air blasting by a factor of 10. Their disadvantage are restrictions to very few media

This process can be costly in terms of tooling, machine programming and materials. Sand casting, on the other hand, is a relatively cost-effective process, with quick set-up times. As discussed in this blog previously, the technique involves pouring molten metal into a sand mould, which contains a hollow cavity of the desired shape.
The sand casting process is a versatile and well understood process. Process refinements over time have helped make sand casting the process of choice for applications in many, many industrial markets. As with most materials and design decisions, a discussion with a metals expert can help drive the best metals decision. For new designs, that is ...
3. In slush casting process..... A. Molten metal is fed into the cavity in metallic mould by gravity B. Metal is poured into die cavity,and after a predeterminded time the mould is inverted to permit a part of metal still in molten state to flow out of cavity C. Cavity is filled with a precalculated quantity of metal and a core or plunger is inserted to force the metal into cavity
