New investment casting process method
In the development and improvement of the conventional process on the basis of the development of new process methods, further improve the quality of castings, improve production efficiency, expand the scope of application of investment casting. The casting of 1978, no. 6, reported the Beijing oil pump oil nozzle factory using cage combination of large mould group process. Cage type of each component, to ensure that the mould group enough rigidity, and also as a pouring system, steel utilisation rate increased by 10%: about. Hebei Institute of Technology, etc. By controlling the solidification time of castings, inner sprue, gate bar, so that M ≤ M ≤ M ≤ M bar, and make the solidification cut-off in the inner sprue and gate bar between the gate bar in the liquid metal pouring back to the furnace cylinder, to achieve the no-gate investment casting.
Precision casting development prospects
Investment casting refers to the use of fusible materials made of fusible model, coated with a number of layers of special refractory coatings, after drying and hardening to form a whole shell, and then steam or hot water from the shell to melt off the model, and then placed in the shell in the sand box, filled with dry sand moulding in its surroundings, and then the casting of the model into the roasting furnace after a high-temperature roasting, casting model or shell by the roasting in which the casting of the molten metal poured to get castings.

What is the effect of metal liquid temperature on disappearance mould casting?
In the production of disappearance mould casting, the quality of the metal liquid has an important impact on the quality of the casting, in which the temperature of the metal liquid will directly affect the processing accuracy and processing efficiency of the casting. So, the temperature of the metal liquid on the disappearance mould casting in the end what is the impact?
What are the factors affecting melting in foundry production?
Interference factors in casting melting, generally not the so-called harmful factors, but refers to the normal process of casting production to play a negative impact on the factors. So, what are the interference factors in casting melting?
Process characteristics when pouring large castings
Large castings pouring location selection of casting quality, modelling methods, sand box size, cast iron plate, cast iron platform machining allowance has a great impact. So in the selected pouring location should be casting quality is the main, generally should pay attention to the following principles: for a large area of thin-walled part of the casting in the lower part of the casting, while trying to make the thin-walled standing or tilted pouring, so that is conducive to the filling of the metal. Due to the mud core is long, the rigidity is not enough, in the liquid metal under the action of buoyancy, the mud core produced as shown in the figure of the dotted line bending deformation. If it is changed to vertical pouring, it can avoid the above bad situation. It will be a large casting of large thin-walled part of the casting below, so that this part can be full of casting under high liquid metal pressure, to prevent underpouring. For some castings that need to make up shrinkage, the thicker part of the cross-section should be placed in the upper part or side of the casting.
