[1] They are designed to easily transport [2] to a site and use with different types of load and cargo with little or no setup or assembly.
There are seven requirements for cores: [2] Green strength: In the green condition, there must be adequate strength for handling; In the hardened state, it must be strong enough to handle the forces of casting; therefore, the compression strength should be 100 to 300 psi (0.69 to 2.07 MPa). Permeability must be very high to allow for the escape ...
Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold.Transfer molding is different from compression molding in that the mold is enclosed [1] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact.
