There are two main types of foundry parts: special foundry and sand foundry. 1. Ordinary sand foundry uses sand as the mold material. There are three types of wet sand molds, dry sand molds and chemically hardened sand molds. Its cost is low and the sand can be reused. But its mold making is time consuming. 2. According to the material, special foundry can be divided into two categories: special foundry with natural mineral sand and gravel as the main molding material and special foundry w...

The Investment foundry Handbook provides mold air permeability versus temperature for the three binders. Today, I want to talk to you about the air permeability of foundry parts shells. The air permeability of the foundry part shell is the best at low temperature. As the temperature increases, the air permeability of the mold shell is continuously decreasing, and the air permeability of the mold shell is continuously rising after it reaches a valley bottom. In fact, the above conclusion is ob...

The quality of the foundry process not only affects the production and operation of the foundry, if it is not handled well, it may also cause foundry defects. Therefore, in order to simplify the foundry process and ensure the quality of the foundries, the foundries must have a reasonable structure. 1. The requirements of foundry quality on foundry structure Foundry parts should have reasonable wall thickness ...

Foundry parts and forging parts are both manufacturing processes used to process metal materials. The difference is that forged parts are hammered and pressed to make the metal material in a plastic state into a workpiece with a certain shape and size. Change its physical properties; and foundry parts are a method of processing the required shape of foundries after melting the metal into a liquid and then pouring it into a mold, cooling, solidifying, and cleaning, and can be made into various ob...

Foundry is the mother of the machinery industry. As long as there is a machinery industry, foundry is needed. For example, automobiles, high-speed rails, and subways all have many mechanical parts. Most of these parts need to be cast to obtain a general shape, and further processing can be used to obtain the parts. There are also more foundries directly applied. It can be said that foundry is by our side. Maybe you can't think of it. We deal with foundry every day. For example, computers, air...
