CVD Coating Service (Manufacturing Update)

September 01 2017 SilcoTek


We took a tour of SilcoTek coating manufacturing, here's what we found out...

Imagine you're a manufacturer offering CVD coating solutions; your customers come from a wide range of industries and applications, from manufacturing high durability inert oil and gas tools, to high purity semiconductor surfaces. 

Now imagine the customer can ship their parts to you on almost no advanced notice in quantities ranging from one part to thousands with sizes ranging from components as big as the letters on this page all the way up to the size of a small piano.  Materials and surfaces can range from 1000 pound stainless steel vessels, to delicate glass vials.  Further complicating the process; parts are shipped with the expectation that the they will be returned in a handful of days in perfect condition with a high durability inert coating.  Welcome to an average day in SilcoTek® Coating Manufacturing.

CVD Coating Service

How do we manage vast differences in customer needs?  We do it through management of a robust and flexible manufacturing system, integrated process control and, most importantly, exceptional manufacturing technicians backed by dedicated engineers and scientists.  In short, everyone contributes to the process of customer satisfaction. 

So what happens to your parts when they arrive at SilcoTek® for inert CVD treatment?  Here's a quick overview: 

Parts are received, and confirmed for quantity, product application, and special handling or process needs.


Technicians work hard to properly screen incoming parts for imperfections or any potential material issues or incompatibilities. 

The part surface is then prepared for optimal quality and adhesion by removing potential contaminants, assuring the surface will support application of our inert, corrosion resistant coatings.

Preparing The Surface


Looking Into Surface Prep Bath


Parts are fixtured and loaded into one of several chemical vapor deposition (CVD) process ovens.  Our team of engineers are able to design fixtures and process vessels specific to your parts.  Enabling the most efficient and high quality inert silicon coating possible.  The process oven loading process can be as easy as placing a small part into a vessel to rigging a part with a forklift truck.

Our patented CVD processes are fully automated with extensive monitoring and safety systems.  A process upset can be detected and alarmed in milliseconds and corrected, assuring a high quality surface.

After processing, parts are inspected for coating quality


Final Visual Inspection


Verifying Sample Surface Energy




After inspection, parts go through a final verification of quantity, coating type and confirmation of shipping.

Then we do it all over again for the next customer.  The positive results of manufacturing's efforts are realized by our growing number of customer fans!

What did we find out during our tour?  SilcoTek is a sophisticated facility staffed with technologists that believe in process control and continual improvement.  This team is all about the process and technology, and they certainly understand surface science!  How many electropolishers, or platers, or glass lining operations staff a team of PhD scientists?
