ES Precision invests profits from successful first year into new UV laser system from Coherent-Rofin

Profits from UK precision laser processing specialist ES Precision's first trading year have been reinvested into a new UV laser system from Coherent-Rofin UK.

ES now has eight laser systems using Vanadate, Nd:YAG, fibre and CO2 sources as well as the new frequency-tripled Vanadate UV source. This keeps ES Precision at the forefront of laser marking and fine drilling/cutting; no other subcontract marking specialist offers such a broad range of laser technologies, according to the firm. The UV laser in particular opens up opportunities that conventional lasers miss as the shorter wavelength is absorbed extremely well by plastics, organics and many ceramics. Pure surface absorption on many plastics usually produces a superior mark to the partial transmission of IR wavelengths from other lasers.

Further, the shorter wavelength of the frequency-tripled laser allows it to be focused down to a smaller spot size than most other technologies, resulting in finer detail or better resolution; especially valuable for ID Matrix marking. 

ES Precision is happy to mark sample parts to find the best solution for any company that needs permanent product identification, decoration or functional marking/engraving/surface modification.
