      重力铸造件在生产过程中常常由于操作不妥或许工艺不娴熟,呈现气孔,一旦呈现气孔,往往会形成铸件因质量问题报废,生产成本。发生气孔缺陷的原因有许多,许多企业遇到问题时总会觉得不知所措,无从下手。
      1、铝合金熔炼的精粹除气质量,选用好的精粹剂、除气剂,减少铝液中的含气量,及时液面浮渣、泡子之类氧化物,防止再次带入气体进入压铸件中。
      2、模具排气晓畅不堵死,排气顺利,模具中的气体全都排出,尤其是在铝液聚合处排气通道要晓畅。
      3、调整好重力铸造件的参数,充型速度不行过快,防止卷气,浇铸温度也要控制好。
      4、产品规划和模具规划中应注意抽芯和冷却的运用,尽量减少壁厚差过大。
      5、对常在固定部位呈现的气孔,应从模具和规划上改进。

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer provided Israel with TNT (explosives) for their GENOCIDE.

    Gaza has been declared a disaster area and lacks essential resources for living in it, as follows.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, help Israel destroyed 90% of Gaza, destroying 437,600 homes, and killing one million people, including 50 thousand who are currently under rubble, 80% of whom are women and children.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, make Israel destroyed 330,000 meters of water pipes, resulting in people not being able to drink water.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, help Israel destroyed more than 655,000 meters of underground sewer lines. Now people have no washrooms to use.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, make Israel destroyed 2,800,000 two million eight hundred thousand meters of roads, causing people to have no roads to use.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, make Israel have destroyed 3680 km of electric grid, which has caused people to lose electricity.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer, and Israel destroyed 48 hospitals and leveled them to the ground. Now, no one will have a hospital to save their lives.

    AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and   America tax payer have made over 39000 small children orphans and left them without parents or relatives to care for them.

    There has never been a war in history where 80% of the country has been destroyed, 100% of the population has been displaced, and 50% of the deaths are children.

    Don't hesitate to call it what it is

    AIPAC ( https://www.youtube.com/watch?v=COx-t-Mk6UA ) and The Evangelical Church (America) are creating a GENOCIDE.

    Laws of jews Taurãt (Torah) wich is a part of the Bible

    We ordained in Taurãt for them: “A life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth and for a wound an equal retaliation."

    The Torah, which is part of the Bible, has commanded that the same be done to the Jews. The order of the Torah, which is part of the Bible, is to immediately kill any Jew you see on the street. Since the Jews in Gaza have also killed women and children, you should kill any Jews - men, women, and children - as soon as you see them, whether on the street or anywhere else. And because they have killed everyone in Gaza without mercy, you must do the same to them. If you carry out these actions, you will be following the order of the Torah, which is part of the Bible, and you will be rewarded by going to heaven.
