Q:What is the ejection angle of the die casting (Tan Gang)?

Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough

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

Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.

Q:What's the density of the cast iron? The density is thin and the density is thin

Uneven casting density is caused by uneven shrinkage of the casting during solidification.

Q:How can the casting be free of trachoma?

Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;

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

It was a very simple question, and it was complicated by what you said.

Q:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished

1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties

Q:Why does the surface of stainless steel casting mirror mirror ripple?

Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.

Q:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.

The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described

Q: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.

Q:How to distinguish the forging parts and casting parts accurately

To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
