Ceramic coated exhaust pipe is one of the most popular cast exhaust manifolds for tube headers. The reason is: it not only durable but also have a long-lasting beautiful finish. Besides, it works as a thermal barrier to prevent heat dissipating too fast.
The ceramic coated exhaust pipes are widely used in automobiles, motorcycles as well as racings. When we get the pipe ceramic coated, the surface color is pale white.
In this article, we will discuss ceramic coated exhaust pipe polishing. These automotive parts made from a rigid metal base material with ceramic coating. Generally, this item is a big size, so we have to polish one by one or in a compartmentalized trough vibratory machine.
1. Parts condition before finishing
Jet-Hot+Headers cerakote polishing with vibratory finishing| Material: stainless steel base material with a ceramic surface coating Appearance: The parts surface is dark and dull before burnishing process. No big burr or scale is observed with the naked eye. Shape: Specially formed tube Size: Customized Process before finishing: Ceramic Coating The process after finishing: Assembling |
2. Parts Surface requirement
- Without parts damage
- Highly reflective mirror shining surface
3. How we process the parts
| Step | (1) Polishing | (2) Drying |
| Machine | Tub vibrator (round wall) | natural drying |
| Tumbling Speed | 50/60HZ (full speed) | |
| Chip type | Zirconia ball 3-4mm | |
| Media to Parts Ratio | 1 piece of the part each time | |
| Compound Type | HM-2 | |
| Water Level | Just cover the mass | |
| Tumble Time | 20-30 minutes | 30 minutes |
| Notes— | Manually take the parts out Of machine, and rinse them | The ceramic coated exhaust pipe is non-rusting |
4. Parts condition before and after polishing
The process of polish ceramic coated parts is fast and cheap. What we need to do is to find a tub vibrator large enough to hold the exhaust pipe.
The tumbling media that we use is zirconia ball which imposes a reflective mirror finish on parts surface. Zirconia ball is non-wearable media which made the process very economical.
Polishing compound is the key to success. We use our magic formulated blend just 200g (about 7 oz) into the vibratory tub machine. Then in 20-30 minutes, we get the super-finished exhaust pipe. It looks as if it is anodized.
You can see the white/grayish coating changed into the high glossy surface after the vibratory polishing process. This surface is aesthetically appealing.
5. Other considerations
Zirconia ball may go through an inner tube of the parts, so we have to clear out all media inside after polishing. The good thing is: the nature of the zirconia ball makes it not stuck inside.
Because of the exhaust pipe size, we can only use tub vibrator to contain these parts. Media of similar types can also do this process, for example, fine porcelain straight cylinder. However, zirconia ball has the best media flow and give best burnishing result for the curved surface.
6. Conclusion
In this article, we show ceramic coated exhaust pipe burnishing with zirconia ball. This process is specially designed for the application. Ceramic coated. Exhaust headers are of the same category to be processed in the same way.
First, we discuss the condition of the parts before finishing.
Second, we show parts surface requirement from clients.
Third, we show transparently the process of how we get it done. Later, we compare the surface before and after mass finishing. At last, we discuss other possibilities for zinc parts deburring and polishing.
