Form and dimension may also be achieved by a number of alternative processes such as hot or cold extrusion, sand casting, die casting, and precision casting.

形式和尺寸也可以通过其它一些可选工艺来达到，比如热挤出或冷挤出加工，沙模铸造，拉模铸造，或精密铸造。

The processes of sand casting are discussed in this section, including patterns, sprues and runners, design considerations, and casting allowance.

本节讨论砂型铸造工艺，包括型模、浇注口、浇道、设计考虑因素及铸造余量。

Green sand casting casting clay weight from a few kilograms until decades kilograms, machine tool lathe bed and clay dry type of casting production can be weighed dozens of tons.

粘土湿型砂铸造的铸件重量可从几公斤直到几十公斤，机床床身而粘土干型生产的铸件可重达几十吨。

Effect of low freqency vibration on solidified behavior of ferro-carbon alloy was inspected in sand-mold Casting.

本文研究了在普通砂型条件下，低频振动使铁碳合金凝固组织的影响。

During this month, I learned lathe work, miller operating, benchwork, digital control processing, sand mold casting, heat treatment, and welding.

在一个月中，我们学习了车工，铣工，钳工，数控加工，沙型铸造、热处理、焊接等等。
