Process - Investment casting Production process

1. Making abrasive tools; Drawing programming according to customer requirements, carve out the product shape of the product model, as shown below.

2. Shoot wax; The wax is melted at high temperature, injected into the mold by the wax shooting machine, and taken out after cooling to make the wax production model.

3. Welding and splicing; The product is linked to the pouring die head with high temperature iron. See the picture below.

4. Make the shell, stick the welded product with glue and drizzle sand. Place in a constant temperature 24 degrees space to dry, dry again with glue, sand, repeat 6 layers.

5 Dewaxing; After six layers of shell drying, the wax parts inside the shell are melted by heating to get the product mold shell. See the picture.

6 medium frequency furnace, pouring; Electric furnace heating melts the molten steel to the desired temperature, and then pours the molten steel into the product model housing.

7 Hulling; After the shell is cooled after the molten steel is injected, the shell is vibrated and broken by the vibrator. For the part that is not cleaned up, the shell will be thoroughly cleaned by the shot blasting machine by spraying the product surface with steel shot.

8. Cutting and polishing; Cut the product off the main body and sand the joints clean.

9. Post processing, custom; Handle clean products according to customer requirements. The figure shows the pickling shot polishing surface, machining treatment, pickling grinding surface, and surface color treatment in turn.

Characteristics and advantages of investment casting

The biggest advantage of investment casting is that due to the high dimensional accuracy and surface finish of investment casting, mechanical processing can be reduced. Only a little machining allowance can be left in the parts with higher requirements. Even some castings can only be polished and polished, and can be used without mechanical processing. It can be seen that the investment casting method can save a lot of machine tools and processing hours, and greatly save metal raw materials. As shown below:
