Engineering material(notes). Quality Control and. The mold can be filled by gravitational forces or under pressure. Measured in this way, Kc has well defined values for brittle materials (ceramic, glasses, many polymers and low toughness metals like cast iron). Ductility The tensile ductility is the permanent increase in length of a tensile specimen before fracture, expressed as a fraction of the original gauge length. They are available as plate, sheet, tube, bar, wire, castings and forgings. For brittle solids: ceramics, glasses and brittle polymers - it is much less than the compressive elastic limit. Modulus of Rupture When the material is difficult to grip (as is a ceramic), its strength can be measured in bending. Steels: Carbon steels are alloys of iron and carbon. The number given as flammability corresponds to a relative rating system, thus using it almost only for comparisons is reasonable. 119-130, Article ID: IJMET_07_01_013 Available online at http://www.iaeme.com/ijmet/issues.asp?jtype=ijmet&vtype=7&itype=1, Injection Molding Process Injection molding equipment Classification of injection molding machines 1.

Generally they have high melting points and high chemical stabilities. A regular focus on technical and semi-technical vocabulary enables learners to become familiar with and practise using the specialist language they need for work. This represents the stress at which the stress-strain curve for uniaxial (=in one direction) tensile loading deviates by a strain of 0.2% from the linear-elastic line. In a two-part mold, which is typical of sand castings, the upper half, including the top half of the pattern, flask, and core is called cope and the lower half is called drag. The nature of their bonding The physical properties can also be further grouped into categories: mechanical, thermal, electrical, magnetic, optical etc. 8, 10 Elastic limit depends on the mode of loading.
