Why is machining an aluminium part so expensive?

The Key Point Is That The Price Of Single Pieces Is Different That Of Batches. If There Is No Batch For Aluminum Alloy Parts Processing , The Unit Price Will Be Higher. First, You Need To Purchase Aluminum Alloy Raw Materials, Make Parts Blanks, Write Programs. Secondly, Prepare Tools, Arrange Fixtures, Set Tools, Find The Origin, Transfer Programs, Process Aluminum Alloy Parts. Finally, Scrape Burrs, Post-Process, Also Pack Ship. This Includes The Cost Of Machine Operation, Programmer Wages, Machine Tool Depreciation, Electricity, Cutting Fluid... These Are All Costs. So Why Is It So Expensive To Process Aluminum Alloy Parts? Every Process Requires A Dedicated Person To Operate. Huiwen Zhizao Is A Shenzhen Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

Cost Drivers For Aluminum Alloy CNC Machining :

1) Processing Time

The Longer The Aluminum Alloy Part Processing Time, The Higher The CNC Cost. Processing Time Is The Main Driver Of CNC Cost.

2) Material Cost

The Cost Of Billet Material Is An Important Part Of CNC Cost. Material Cost Can Be Reduced By Optimizing The Design To Use Standardized Billets As Much As Possible Reducing Waste. At Present, Aluminum Alloy Is One Of The Raw Materials With Relatively Moderate Price Good Processing.

3) Installation Time

When The Batch Size Is Small, The Preparation Of The Geometric Model The Planning Of The Machining Process Seriously Affect The CNC Cost Of Aluminum Alloy Parts. This Part Of The Cost Is A Fixed Cost Can Be Amortized Through Large-Scale Production.

4) Other Design Factors

When CNC Parts Processing Design Has Special Requirements (Such As Precision Tolerance Requirements Thin-Wall Design), Special Tools, More Precise Quality Control, Lower Processing Speeds, More Complex Processing Steps Are Required, Which Will Seriously Affect The CNC Cost. Huiwen Has Long Been Committed To The Processing Of High-Precision, High-Difficulty, Easy-To-Deform Metal Plastic Parts , Small Medium-Volume Production Of Light Alloy Composite Materials (Such As Aluminum Alloy, Carbon Fiber, Etc.),  Robot Parts Procurement Customization Services.

Without Such Cost Awareness, An Engineer Is An Engineer, But Just A Draftsman Who Can Use Creo, UG Solidworks. Some Engineers Think That Cost Is The Business Of The Enterprise, Whether The Enterprise Is Profitable Has Little To Do With Them. In This Regard, I Can Only Hope That You Will Be Laid Off When The Enterprise Lays Off Employees.
