Precision Casting Refers To The General Term For The Process Of Obtaining Precision-Sized Castings. Compared With The Traditional Sand Casting Process, The Castings Obtained By Precision Casting Have More Precise Dimensions And Better Surface Finish. Its Products Are Precise, Complex, And Close To The Final Shape Of The Part. Can Be Used Directly Without Processing Or Processing. It Is An Advanced Process Of Near-Net-Shape. And It Can Be Suitable For Low Quantity Request Orders.
Precision Casting Commonly Used Is Investment Casting, Also Known As Lost Wax Casting. It Is Widely Used For Producing Ferrous And Nonferrous Metal Casting.
What Is Precision Casting Processes?

As Per The Drawing, Our Engineer Will Finish The Mold Design. The Mold Is Purchased From A Mold Factory.
Step 2. Wax Injection
The Wax Is Being Injected By A Machine. Wax Design Of The Desired Castings Is Produced By Injection Molding. This Process Is Called Patterns.
Step 3 . Assembly Tree
The Patterns Are Attached To A Central Wax Stick, Called A Sprue, To Form A Casting Cluster Or Assembly Tree.
Step 4. Shell Making
The Shell Is Built By Immersing The Assembly In A Liquid Ceramic Slurry And Then Into A Bed Of Extremely Fine Sand. Up To Six Layers May Be Applied In This Manner. The Shell Will Be Dry In Each Layer Making.
Once The Ceramic Is Dry, Then Heating. The Wax Will Be Melted Out. The Melted Wax Will Be Flow Out From The Shell.
Step 6. Casting
In The Conventional Process, The Shell Is Filled With Molten Metal By Gravity Pouring. As The Metal Cools, The Parts And Gates, Sprue, And Pouring Cup Become Solid Casting.
Step 7. Knockout
When The Metal Has Cooled And Solidified, The Ceramic Shell Will Be Broken Off By Vibration Or A Knock-Out Machine.
Step 8. Cut Off
The Parts Are Cut Away From The Central Spruce Using A High-Speed Friction Saw.


After The Casting Was Cut Off. The Casting Pouring Part Will Be Ground Carefully.
Step 10.Inspection And Post Treatment.
The Casting Will Be Inspected By The Inspector As Per The Drawing And Quality Request. If There Are Unqualified Parts. It Will Be Repaired And Inspected Again.
Step 11. Finished Castings
After Surface Finishing Operations, The Metal Castings Become Identical To The Original Wax Patterns And Are Ready For Shipment To The Customer.

The Advantages Of Precision Cast Iron Include

Precision Cast Iron Parts Are Capable Of Achieving More Complex Shapes And Design Requirements Because The Casting Process Enables The Creation Of Finer And Precise Casting Molds That Can Achieve Higher Complexity And Detail.
-High Precision
Precision Cast Iron Parts Can Meet Dimensional Accuracy And Surface Quality Requirements. By Adopting Advanced Casting Technology And Precision Machining Technology, Higher Workpiece Accuracy And Surface Quality Can Be Achieved.
Cast Iron Has High Strength And Hardness, As Well As Good Wear Resistance And Corrosion Resistance. Precision Iron Castings Can Further Improve The Stability And Consistency Of Material Properties By Controlling Alloy Composition And Heat Treatment Processes.
-High Productivity
Compared With Other Manufacturing Processes, Cast Iron Casting Has Higher Production Efficiency And Is Suitable For Mass Production. This Is Very Important For Mass Production And Cost Control.
