When looking into the different types of precision metal forming for custom parts, you will find that you have a lot of options. How do you choose between CNC machining, hydroforming, and metal stamping – three of the most popular services available for components production? At Stuecklen Manufacturing Company, we offer both CNC milling and sheet metal hydroforming for their benefits over traditional stamping.
- Low Production Runs Possible
- Prototyping, Repair Parts, One-Offs
- Speedy Production
- Lower Production & Tooling Costs
- Decreased Waste Of Materials
- More Flexibility
- Low Set-Up Times
- Less Finishing Required – If Any
- Most Ductile Metals – Aluminum, Steel, Brass, Copper & Many Alloys
- Specialized Niches
- Easy To Change Designs
Similarities & Benefits
You can see why both CNC turning and metal hydroforming are the first option for the medical, transportation, and architecture industries. You can quickly and economically produce parts with no wrinkling or warping and a virtually seamless finish. Now let’s take a closer look at which of these efficient options may best suit your specific project.
When To Choose CNC Machining
CNC or Computer Numerical Control machining is a form of automated metal spinning. Computer software controls the movement and pressure of the spinning lathe and mandrel used to form your parts. Automating this process increases accuracy, but you may still need some finishing services to get the look you want.
This capability works best for bowl or bell-shaped parts.
- Speed & Precision
- Accuracy, Repeatability & Consistency
- Any Ductile Metal Is Suitable
- Some Marking Possible / Finishing Potentially Required
- Better For Bowl-Like Or Bell Shapes
- Skilled CNC Operators Required
When To Choose Hydroforming
Hydroforming uses hydraulic pressure and an elastomeric (rubbery) bladder in place of a traditional female stamping die. So, if any re-tooling or adjustments are needed, it will only be to one die. Once you get your male die right, you can expect almost no wear and tear over time because there is no metal on metal contact during this forming process.
The uniform pressure applied during this efficient process keeps the strength and durability of your materials intact. It also produces superior finishes with no seams time after time. Where hydroforming really shines though, is in the complexity and irregularity of the parts possible.
This is the ideal solution for engine components, suspension parts, instrument panels, and other lightweight, intricate components and assemblies.
- Great For Both Low & High Volume
- Only Male Die Needed
- More Complex Parts
- Doesn’t Need To Be Round – Intricate / Irregular Shapes
- Material Integrity & Durability Is Preserved
- Multiple Parts In One Run – Great For Assemblies
- Less Stress & Strain On The Starting Material
- Blemish-Free Finishes
