Q: How to calculate the price of casting parts?: Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.

Q: Why does the precision casting factory not usually make iron castings?: The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

Q: What are the casting parts processing engineering?: At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.

Q: How can the casting be quenched and tempered?: Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.

Q: How to distinguish the forging parts and casting parts accurately: Distinguish from performance:The processing performance of forged parts is higher than that of the same material. The forging parts are compact and have good mechanical properties, but the casting parts may have sand holes, holes, shrinkage holes and other defects, and their mechanical properties are inferior to those of forgings. At the same time, forging processing can ensure the continuity of the metal fibrous tissue, fibrous tissue to forging and forging shape consistency, metal streamline integrity, can ensure the parts with mechanical properties and long service life good.

Q: Where is the precision casting factory?: Shandong, DongyingThe birthplace of precision casting

Q: Which surface is coarser for cast iron or cast steel castings? Why?: The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.

Q: When there is no flaw detection for large casting parts, is there any crack inside?: Cracks are considered serious levels of defects and should be repaired

Q: How to solve casting defect casting?: Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
