- Q:As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
- Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
- Q:What is the difference between forging parts and casting parts?
- The forging can guarantee the continuity of the metal fiber tissue, make the fiber structure of the forging keep the same shape as the forging, the metal streamline is complete, the tissue is compact, and the mechanical property is good. To ensure that the object has good mechanical properties and long service life, the processing of objects sharp, durable, high strength, first-class quality.
- Q: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.
- Q:Where is the precision casting factory?
- Shandong, DongyingThe birthplace of precision casting
- Q: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.
- Q:The casting defects of pores, trachoma how to repair?
- Metal repair can be used to fill the repair. Airhole 2mm following LT102 recommend the use of liquid metal repairing agent.
- Q:Heat treatment process and purpose of casting parts
- Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
- Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q:Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
- General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
- Q:The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
