Precision Capabilities
+/- .005mm Tolerences
Tolerances as precise as +/- .005mm on one or more dimensions of an extrusion, depending on its shape.
0.4 mm Walls
You can make walls as thin as 0.4 mm on one or more dimensions of an extrusion, depending on its the shape.
1.2 mm Holes
Few extruders can handle 1.2mm holes with +/- 0.03mm tolerances, but many trust Partzcore with this challenge.
Functional
Electronic Comm
Partzcore excels in producing complex aluminum extrusion profiles like card guides, and housings, consistently meeting the strict tolerance demands of various industries.
Heat Exchange Devices
We’ve made hundreds of heat pipes, heat sinks, and header bars in all kinds of shapes. They often have complex geometries that require tight tolerances to work well
Component Carriers
Another area where we see tight tolerances is carriers for electronics and other industries. The parts are often tiny and are held in openings that must be held to 0.025cm accuracy.
Large Aluminum Extrusions
One way to measure the size of an extrusion is by the diameter of the smallest circle that will fit around its cross-section. This is called the circumscribing circle diameter (CCD). The CCD affects the cost of making the extrusion. Most standard profiles have a CCD of less than 12 inches. However, some extruders can make extrusions with a much larger CCD, up to 32 inches.
Aluminum Extrusions
About 80% of all extruded metal products are made from aluminum. It is used in many industries, has good mechanical properties, can be finished in various ways, and is very malleable, making it perfect for extrusion. Most aluminum alloys used for extrusion are light, don’t rust, and have good thermal and electrical conductivity. Each alloy has its own special features.
If you need stainless steel, brass, copper, or other metal extrusions, we’re happy to talk to you about them and see if we can help.
Extruded Aluminum Alloys Comparison
Aluminum 6061
6061 is a versatile alloy that can be heat-treated to a variety of forms, including 6061-T6. It has two main alloying elements, magnesium and silicon, which give it very good strength, durability, and weldability.
High strength and toughness; Great corrosion resistance; Good fatigue resistance; Doesn’t respond as well to finishing; Heat treatable
Transportation components for automotive and marine environments
Extruded Aluminum Alloys Comparison
Aluminum 6063
6063-T5 is an inexpensive heat-treatable alloy that has smaller grains than 6061 alloys. It is used more often for extrusions than 6061. It can make parts with thin walls and works well with finishing processes. As a result, it is often used for decorative purposes.
Responds well to finishing; Great corrosion resistance; Easily extruded and economical; Ideal for thin-wall applications; Relatively low strength; Heat treatable
Decorative trim, heat sinks, architectural components
Available Finishes
This finishing option is the fastest available. Parts may have visible tool marks and possibly sharp edges or burrs, removable on request.
You can use sandblasting to peel paint, smooth out rust, take bumps and mars from stuff, and basically make things clean. Ironically, you can also sandblast things to scuff them up by etching the surface and give something a little bit of ‘tooth’ so that paint will stick better.
Type II anodizing enhances corrosion resistance. It allows parts to be colored in various shades like clear, black, red, and gold, typically for aluminum. Type III provides a thicker, wear-resistant layer as well as the corrosion resistance of Type II.
This process involves spraying powdered paint onto a part, which is then heated in an oven. The result is a tough, wear- and corrosion-resistant coating, more robust than traditional paint methods. A broad range of colors is available for achieving the desired look.
Plating involves coating a conductive surface with a thin metal layer. This method is often used to prevent corrosion, enhance durability, modify surface friction, and boost aesthetics.
Good Aluminum Extrusion Design Practices
1. Balanced walls
2. Generous tapers
3. Avoid/minimize hollows
4. Use grooves, webs, and ribs
5. Minimize perimeter/cross-section ratio
6. Practice symmetry/minimize asymmetrical detail
You’ve got enough worries, let us take care of your parts.
QC will verify that the part material, features, and finish are in accordance with the part requirements specified in the PDF file, CAD file, and/or STEP file.
QC will conduct an examination using precise instruments to document every dimension, attribute, positional measurement, and specification as outlined in our Statistical Sampling Strategy.
QC will conduct a thorough inspection using a Coordinate Measurement Machine (CMM). This will document all dimensions, attributes, locations, and notes in accordance with our Statistical Sampling Plan.
The First Article Inspection aims to confirm that all engineering designs and specifications are fully understood, addressed, verified, and recorded. QC will keep a detailed quality log for customer oversight of responsibilities and planning. This includes conducting regular checks and audits to ensure compliance, assessing the root causes and corrective measures for any discrepancies, and investigating issues.
If your part needs additional inspections, such as Non-Destructive Testing, Serialization, Custom Sampling Plan, or if you want to use your own inspection datasheet, please let us know.
