Product Description

Gravity Die Casting Aluminum casting oil pan 

Most of the engine oil pan or transmission was make by the stamping steel ,but some of them was made by aluminun casting and CNC machining production process,here by we would like to share some of our experience from our customer ,please let me know if you like it ,I can share my customer contact information for you if you like it ,this case was develop casting aluminum pan instead of stamping steel pan 

This page was special for the customer who want to develop the casting aluminum oil pan ,if you want the exactly same oil pan we recommend to get it from myfavor customer in USA,because they pay for the mold cost and the mold belong to them  ,so we need to respect that .Beside they own the develop data .

1.Raw material

2.Casting mold prepare

3.Casting engine oil pan

4.CNC for the engine oil pan or deep sump

5.Polishing the engine oil pan after CNC machining process

6.Inspection bolt hole for Engine oil pan

7.Casting engine oil pan raw material A365

8.Design casting mold for engine oil pan

1.Raw material for casting engine oil pan or oil sump deep sump 

The right casting raw material was the key for the engine oil pan ,engine oil sump was a key part for the engine it storage the engine oil inside the pan for lubrication whole engine ,whatever the canshaft ,camshaft ,piston ,connect rod ,they all need the oil for lubrication ,the oil start with the pan thought the oil pump by oil strainer oil screen or we called it as oil pickup tube.

Normally we use A365,A380,6061,7075,2024 raw material for casting the engine oil pan ,the chemical composting as below 

A365 T6 and A380 was much more better for the casting due to the raw material flow and move inside the casting mold.

2.Casting mold prepare for engine oil pan 

1.Get data from the sample of engine oil pan

When we got a oil pan from cutomer and they decide to develop it as aluminum casting engine oil pan instead of the stamping one ,those were the things we need to prepare ,the first step was making a casting mold for engine rear oil sump .The casting was much more easy than the stamping what we need to do was the mold ,the casting engine oil pan mold was the key for the oil sump or oil pan 

The first step for the casting mold for engine oil pan was the data from the sample or 3D drawing from customer,some of us called reverse engineer for engine rear oil sump because OEM factory didnot share the data of the engine oil pan for aftermarket ,so we need to reverse engineer for the oil pan first

We would like to share it step by step  

Got the sample of engine oil pan 

Uploading the data to stl

We would like to use the handy scanner to get the profile of all the engine oil sump ,Normally the engine oil pan had a lot of profile due to the stamping steel limit ,so what we need to do was getting all the data from it especial the profile 

We will upload the data by stl for the next develop ,whatever we use the solidwork UG Geomagic design,we need the data as stl then we transfer to stp or igs as edit for next casting improve.

3D plastic print for fitment test for the engine block

1.The thickness of the casting aluminum engine oil pan was different than the stamping steel .The min thickness for the engine oil pan should be over 6mm ,the stamping steel was just about 1.5mm thickness ,so to improve the capacity and fit the engine block bolts holes,we need to test the fitment before the casting mold was kicking off

2.The 3D plastic print can be control the tolerance within 0.5mm so we think that was enough to test the engine oil pan .

Once we got the confirmed from the customer then we can kick off the casting engine oil pan mold ,otherwise we need to get the correct for the oil pan where it interfere with the other part then we re 3D print again to test the fitment 

3.The fitment was very important step ,if we didnot do it we may meet the situation the part cant be install on the car in the sample production then we need to correct ,so to save the cost for develop aluminum casting engine pan that was quite important

2.The casting mold kick off production for engine oil sump

If we pass the first step of kick off fitment then we move to the casting mold production for truck engine oil pan 

Car oil pan Casting mold production 

Truck for engine lower mold production 

The casting mold was the key for the engine oil pan ,we need to simulation it before kick off the production of the mold

The profile of the casting engine oil pan ,truck oil sump lower mold

Engine oil pan casting process

1.When we got the raw material and melt it with temperature about 700°,we take the aluminum water from the melt tank 

2.Then we fill the aluminum water inside the mold

3.When it was cool down we get out the part from the mold

4. Gravity Die Casting for engine oil pan 

Why we choose gravity die casting

-  Excellent mechanical properties : Slow cooling improves metallurgical integrity.  

-  Good surface finish : Better than sand casting, though not as smooth as die casting.  

-  Cost-effective for medium volumes : Balances tooling costs and production speed.  

-  Moderate tooling costs : Higher than sand casting but lower than die casting.  

-  Limited complexity : Less suited for intricate designs compared to die casting.  

-  Longer cycle times : Slower than die casting but faster than sand casting. 

 Best for : Medium-volume orders where strength and surface quality are critical.  

Aluminum Casting workshop

The below was the workshop for the aluminum casting,when casting it we will need take the air port and the extra raw material from the casting part away

Gravity Die Casting oil pan sample

The sample of the engine oil pan was come out with main profile and waiting for move to next production 

This was the raw oil pan by the casting and blasing 

We need to check the crack and surface finished before move it to the machining production 

Polishing Engine Oil Pan after fine blasting 

The surface of engine oil pan after polishi

To improve the surface quality of the engine we make the pan by polishing 

We need to go though about 4 process of the polishing 

We take away all the casting surface of the engine oil pan and make it as shiny as possible 

Zero point for CNC

Engine oil pan install blot hole

CNC for the surface

When we load the engine oil pan to the CNC machine ,we need to check the zero point for the setup before to kick off the CNC

We made the engine bolt hole first to fit the engine block

The final step was for the surface flatness ,we machining it by the cnc tooling
