FAQ

What are the factors affecting the machining process of the casting material and structure?

The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.

What are the requirements for casting steel castings?

4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface

My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?

The common material that can be anodized is aluminum alloy. It is recommended to use casting aluminum alloys, such as ZL102 and ZL105, which are commonly used as cast aluminium alloys. The processing of aluminum casting is easy. After processing, the surface of the whole part can be anodized. The color can be chosen.

What are the casting parts used to test shrinkage holes?

2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.

How much is the amount of electrophoretic paint per square meter used in the casting?

In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.

When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!

Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.

The casting defects of pores, trachoma how to repair?

Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.

When there is no flaw detection for large casting parts, is there any crack inside?

According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
