Why 'Ductile Iron
'Spheroid Graphite' or 'Ductile Iron' is a unique form of Iron. which prior to the metal casting process receives crucial mineral additives to produce an exceptionally strong resistance and durable metal, the molecular structure of 'Ductile Iron' gives rise to excellent additional strength and shock load resistance, within structure carbon steel, without steel inheriting corrosion. In today's roads, Covers & Gratings are required to carry increasingly heavy and fast moving traffic, yet the need to keep the roads in service, places free from accidents and theft, additional demands on those Covers and Gratings in terms of speed and ease of access for maintenance of services is essential. 'Ductile Iron' Manhole Covers, Gratings and Frames are fast replacing the conventional 'Grey Iron Manhole Covers, Gratings and Frames on account of uniqueness in its Strength to Weight ratio, Design, Weight and the Cost benefit.
A match-plate pattern is similar to a split pattern, except that each half of the pattern is attached to opposite sides of a single plate. The plate is usually made from wood or metal. This pattern design ensures proper alignment of the mold cavities in the cope and drag and the runner system can be included on the match plate. Match-plate patterns are used for larger production quantities and are often used when the process is automated.
Cope and drag pattern:
A cope and drag pattern is similar to a match plate pattern, except that each half of the pattern is attached to a separate plate and the mold halves are made independently. Just as with a match plate pattern, the plates ensure proper alignment of the mold cavities in the cope and drag and the runner system can be included on the plates. Cope and drag patterns are often desirable for larger castings, where a match-plate pattern would be too heavy and cumbersome. They are also used for larger production quantities and are often used when the process is automated.
