Sand Casting - Panel

此询盘采购上www.MFG.com在 USA 作 砂模铸造


Production of a Sand Casting - Panel. Approximately 19.0inch x 5.22inch x 1.0inch. Material should be Aluminum Alloy- SR319, self-aging.

Buyer is looking for sand cast blanks, which will get secondary and final machining to dimension.

Therefore, Buyer is looking for raw cast parts, which will be machined to final dimensions. Casting must be close to the high side of the final tolerance dimensions as possible (to minimize final machining time).

Attached drawing was originally for a part which was to be made from a billet.

Please quote in two ways:

1. Quote this with making the casting only! Final machining will be done by Buyer, to get secondary and final machining to dimension.

2. Quote the casting for this part along with machining to final dimensions. This is only if Supplier has CNC machining capabilities.

If Supplier can do the casting and the final machining, please quote the part both ways.

If Supplier can only provide the casting, then quote only the casting.

In either case, list which option is being quoted.

Also, list in the quotation how much over the high side of the dimensional tolerance the casting will be made. This is so Buyer can determine how much machining time will be necessary, to machine the casting to its final dimension.

When quoting the casting tool, be certain that it is of the quality to make 500 casting per year, for a 3 to 5 year period, without additional cost for tooling maintenance.

砂模铸造: 砂模铸造是应用广泛的铸造形式。 正如名称所示,就是用砂子制造铸模。 砂模铸造需要在砂子中放入成品零件模型。 然后在模型周末填满砂子,从而形成铸模。 如果在浇铸金属之前,必须取出模型,则铸模应做成两个或更多个部分。 必须对铸模进行修改,使其具有向铸模内浇铸金属的孔。 铸模保持适当时间,一直到金属凝固。 取出零件后,铸模被毁,因此必须为每个铸造件制作新铸模。 砂模加工厂可以铸造大型零件。 铁铸造、青铜铸造、黄铜铸造与铝铸造都可以使用砂模。 湿型铸造是另一种砂模铸造工艺,它的造价低廉,而且可以生产各种尺寸的零件。但是,零件光洁度普遍不高,而且尺寸公差也无法控制得很小。 铸造件需要进行其他加工。 湿型砂模可用于生产铁铸件、钢铸件、不锈钢铸件以及铜、镁与镍合金铸件。
