How To Choose The Part When Pouring Stainless Steel Casting

1. Lost foam casting stainless steel foundry should try to put the vaporization mold with open parts, such as the dialog box, the main bone and its concave groove, which are placed downward, which is conducive to the sand filling modeling design and ensures tightness.

2, production and processing surface: foundry for a very important production and processing surface, should be placed downward or vertically, because the vaporization mold when encountering continuous high temperature metal liquid slag, it is easy to float to the above of the casting, the production processing surface can be guaranteed, of course, lost foam casting stainless steel casting manufacturers ideal is can be adjusted to the set mouth.

3. The large plan of the appearance should still be placed vertically or obliquely: the experience of the lost foam foundry in the production process shows that most of the mixed shortcomings formed by the air outlet pores and pyrolysis gasified sediment occur on the surface of the face, while the downward surface or the side building façade is all smooth, and the probability of shortcomings is particularly small. For lost foam casting, the foundry placement can avoid the deformation of the large plan in the case of sand filling shape, and can also avoid vaporization mold when encountering continuous high temperature metal liquid, dissolves vaporization at the same time in a large scale, has the effect of inhibiting vaporization speed, and at the same time reduces the interval between magnetic density and metal liquid mirror glass, prevents the shortcomings of collapse box, and ensures that pouring can be carried out smoothly.

4. In the case of selecting the pouring area, it is also necessary to facilitate the establishment of the spruer system and the safety channel of slag discharge and exhaust pipe.

5. When casting parts, the more common thing in the lost foam foundry is the bottom injection pouring system, but because the vaporization mold itself is stuffy, when pouring, the sample is continuously high temperature metal liquid pyrolysis substance and air, this substance and vapor key is to the gap of the molding sand and the vaporization mold and the metal mold casting intermediate gap to clean out, so vertical or skewed placement is more conducive to the cleaning of vapor and impurities, to prevent the shortcomings of sand pipe and scab.

How should foundries produce stainless steel castings?

1. During production, the foundry needs to find the middle position of the stainless steel casting to ensure that the difference surface of the stainless steel casting needs to have a suitable processing amount.

2, stainless steel casting processing methods are generally divided into two types, one is primary processing, one is deep processing, stainless steel casting manufacturers can also be selected according to customer regulations, the manufacturer should pay attention to the unilateral side to leave a certain capacity.

3. If the bottom of the stainless steel casting needs to be produced and processed, the foundry should try to avoid production and processing, as long as you can see the light, if the bottom end has no shortcomings, you can also immediately produce in time, if there is a capacity of about millimeters, then you need to carry out refurbishment deep processing.

4, deep processing of the inner hole, relative height level also have specifications, foundries need to control according to the amount of error, if the casting has shortcomings, can be repaired after welding and then go to deep processing.

5. If the foundry encounters external shortcomings in the manufacturing process, it is necessary to repair the appearance of stainless steel castings. Generally, arc welding or other means can be used for grinding and polishing, which can not only effectively reduce the loss of the production process, but also maintain the cleanliness and smoothness of the castings.
