Both the experimental analyses and computer simulation were conducted to determine the statistical relationship between the structures and mechanical properties of centrifugally cast TC4 alloy in ceramic-shell mould.

摘 要：实验与模拟计算相结合研究Ti-6Al-4V(TC4)合金在陶瓷壳型离心精铸条件下，铸件模数对凝固过程冷速的影响，以及铸件组织、性能随模数和冷速之间的统计关系。

For the casting characteristics of more complex shape, the two ingates were designed at the same time. The casting was divided into 4 positions to calculate the volume of the riser, and the chill was used in order to obtain the directional solidification sequence.

根据铸件形状较复杂的特点，设计了两个内浇道；将铸件划分为4个补缩区域进行补缩，并配合冷铁来实现铸件的顺序凝固。

On the contrary, a kind of coarser structures and some metallurgical drawbacks, such as micro-holes and shrinkages, will appear in the mould-cast alloy thus mechanical properties of the latter is poorer than that of the former.2 When in different part or the casting thickness not equal, the die-casting magnesium alloy AZ91D has different mechanical property.

压铸镁合金AZ91D的组织由均匀细小的近球状组织和细小的放射状枝晶组成，相比较而言，砂型铸件组织粗大，易产生气孔、收缩等缺陷，故而其力学性能比压铸件要差。 2。压铸镁合金AZ91D铸件依部位和厚度不同，力学性能也不同。

The results show that the surface quality of magnesium alloy die casting improved greatly with the increase of the velocity of high-speed injection stage in a cert.

针对汽车发动机缸盖罩盖零件，采用压力传感器，通过对铸件的表观质量进行评定及铸件密度和抗拉强度的测定，系统研究了镁合金压铸过程中快速充型速度和起速位置对型腔内压力变化和铸件质量的影响。

Section views of the casting along with X-ray photographs can be seen in Figure 3. A pressure-tight power train casting, the oil pump filter housing requires leak tightness at 5 bar.

铸件剖面及铸件 X 射线照片如图3所示，此产品是需要承受高压的铸件，油泵过滤器壳体需要的防漏压密封压力为5 bar 。

I am in improving product quality assurance system, rely on advanced casting equipment and technology, investment casting, casting process silica sol, professional deal with all kinds of complicated structure castings, good at all kinds of stainless steel precision castings, the main products cover : Pipe valve, fast connections, marine hardware accessories, hardware and tools, construction hardware, machinery hardware, locks series, doors and windows furniture accessories, kitchen and toilet hardware accessories (pot handles, burning stalk, ears covered ), Flange, such as Castings, products widely used in machinery, construction, shipbuilding, automobiles, household, medical and other fields.

With the continuous development of the high compacted molding methods and technique, the quality of casting especially their surface quality and size accuracy have been increased significantly, and the rate of waste product was reduced greatly. The degree of ramming of sand mold was improved highly, but the sizes of cavity were changed by the springback of sand mold at the same time, and then it causes the variety of the sizes of casting.

随着高紧实度造型技术和方法的不断发展，铸件的质量尤其是表面质量和尺寸有了很大的提高，大大降低了废品率，但是在砂型紧实度提高的同时，由此产生的型砂回弹改变了行腔尺寸，引起铸件尺寸的变化，成了制约铸件精度和质量的重要因素。
