Iron of technology of hardware iron line casts a technology

Iron of technology of hardware iron storage rack casts a technology

As the development of science and technology, our country is casting a domain own research and development a lot of advanced casting are caused model technology, make cast course of study to have flying progress. In the meantime, cast ceaselessly to large change, Bao Bi is changed, integration develops, also raised new taller requirement to cast quality. For example, complex to be being put in the large Baobi of hot item cast undertakes fusible pattern nicety is cast, because cast heats up a section to be in figuration difficulty, easy generation shrinkage cavity, shrink loose quality problem, because this heat section fills,shrink a difficult problem in becoming fusible pattern to cast. Current, domestic and international it is it is difficult to increase the method that irrigates rising head weight to solve large nicety to cast a hot item to be in figuration through using complex gating system to reach mostly cast difficult problem. But because its gating system is huge, technology makes rate is low, production difficulty is great, create the great waste of raw material and the sources of energy.

To solve problem of this one technology, we pass many test, research success is greater to existing the new technology that the miscellaneous cast of large Bao Bifu of hot item has nicety casts figuration. Do not use complex gating system, do not increase irrigate rising head weight, and use put in the place that heat up a section " cast Leng Tie " method, better land solved the large Bao Bifu that is put in larger hot part nicety of miscellaneous cast fusible pattern casts figuration to heat up a section to fill shrink problem.

Introduced lever of edge of grid of electrovacuum parts of an apparatus to use makings and electron yuan down-lead of parts of an apparatus reachs his to machine new technology with new material. Emphasize the key in stating the new technology that uses law of casting make friends to produce plating nickel and tin-plating to use deoxidization copper to include iron line and manufacturing process. With eletroplate often the law is compared, public errand of sex of the product machinery property that produces with new technology, deflate, spot welding sex, thermal conductivity, chemical stability and exterior quality, dimension all good, the price low, crop tall, economy is sound.

Nicety casts the process of figuration new technology to be as follows:
Profiling of → of design of technology of part drawing → is designed (in the consideration when profiling is designed Leng Tie is installed) → makes profiling (profiling repair) → of production wax-pattern of → of makings of → preparation candle repairs wax-pattern → wax-pattern to examine marvellous → of → production runner makes Leng Tie of Leng Tie → .
