Q:Shandong foundry, casting small pieces of precision casting

Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,

Q:ZGMn13 casting parts processing, with what knife head good?

The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger,

Q:Is the cast steel a casting part?

Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.

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.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.

Q:What is the casting material?

Commonly used gray cast iron, malleable cast iron, ductile iron, cast steel, etc., non-ferrous metal casting copper alloy, casting aluminum alloy, casting zinc alloy, etc..

Q:The difference between cement sand castings, resin sand castings and vacuum casting parts

Vacuum casting is the process of using ventilation molds. Molten metal flows into the mold by air pressure, and then removes air to form a vacuum. The casting process is mainly used for small parts or jewelry with exquisite detailsCompared with the traditional clay sand casting, heat hardening resin sand casting production with low surface roughness, high precision, good quality characteristics, dimensional accuracy of resin sand mold after hardening with good rigidity and high, and not easy to deform, so in the choice of process parameters, mechanical processing you can select a smaller margin, thereby reducing the consumption of metal solution and machining cost, which can improve the dimensional accuracy of castings.

Q:In the design of casting steps and precautions, for casting design, we have what experience?.

Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;

Q:What are the casting parts processing engineering?

Among them, special casting has metal mould casting, pressure casting, low pressure casting, lost wax casting (also known as precision casting), shell casting, lost foam casting, centrifugal casting, continuous casting, V casting, and clay casting

Q:What's the effect of casting copper?

Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.

Q:Heat treatment process and purpose of casting parts

Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
