Razor Blade Coating | DCMS30 Razor Blade Deposition System

The DCMS30 Deposition System is specifically designed to apply coatings to the edges of razor blades. These coatings can consist of various single materials or combinations, depending on the target materials installed.

The system is capable of handling batches of 90,000 double-edged (DE) blades or 180,000 single-edged (SE) blades. The entire process, from start to finish, takes less than 30 minutes air-to-air.

Furthermore, the system can be easily customized to deposit various materials, such as Chromium, Tungsten, Titanium, and other refractory metals along with their nitrides.

Advantages of the Design


Target material can be thicker giving longer target life - up to 6 months between target changes

Sputter rate up to 10 times faster than conventional triode or RF operation, giving faster deposition cycle times

Techniques allowing you to keep pace with evolving technology changes

A variety of target materials can be sputtered using DC pulse magnetron sputtering

Chrome/Platinum targets ensures the composition of the coating will remain constant

Superior uniformity of coating over the whole blade stack

The system is designed to be robust, reliable & easy to operate using semi-skilled operators. This system also has the added facility of an etch/clean of the blades prior to deposition to remove oxides & water vapour from the surface of blade edges.  

The system is pumped using a 1500 l/sec cryo-pump backed by a 210m³/hr roots /rotary pump combination for fast roughing & high vacuum pumping speeds. The cryo has a hot gas Nitrogen purge for fast regeneration cycles to minimise maintenance downtimes.

The substrate table holds 30 rotatable biased bayonets, each bayonet will hold up to 3,000 double edge blades or 6,000 SE blades (0.1mm thick blades) giving a total capacity of 90,000 DE or 180,000 SE blades per run.

The system employs 2 rectangular unbalanced magnetron cathodes mounted on a central rotary services housing for sequential sputtering operations. The cathode target assembly will rotate 360 degrees whilst sputtering to coat all the blade stacks uniformly, providing 15% uniformity over the whole blade stack. The magnetrons have clamp-on targets allowing the sputter targets to be changed within 30 minutes without breaking vacuum seals.
