The requesting of metal castings takes a specific measure of time and vitality to qualify a potential provider foundry.

ASTM or other broadly perceived details ought to be utilized at whatever point conceivable to recognize the material and assessment necessities. See material specifications and SOUNDNESS below.
- Actual or assessed casting weight. Genuine weight data is liked. Evaluations can be given by the provider foundry without real weight data, yet this may require offering costs that are liable to changes dependent on the real weight of the casting(s) being referred to at the hour of creation.
- Drawing. Machine drawings are favored over casting drawings. Drawings or portrayals are compulsory if tests or examples are not accessible silicone vacuum casting. Drawing ought to incorporate dimensional resiliences, signs of basic zones and surfaces to be machined. See MACHINING below.
- Pattern. On the off chance that examples and center boxes are accessible, the solicitation for a citation ought to demonstrate the sort, condition and set up of the gear. See PATTERNS below.
- Production/conveyance plans required. Present and foreseen need ought to be remembered for citation demands.
