BEP Surface Technologies provide a high quality service for the precise deposition of hard chromium.
We have the facility to hard chrome plate a large range of components from small shafts and bores to large laminating cylinders, cooling rolls, conductor rolls, turbine rotors, pump shafts, calender bowls, and printing rolls etc.
Chromium offers extreme hardness, from 900 to 1150 HV, low co-efficient of friction, excellent resistance to wear and abrasion and is resistant to most chemicals. The coating also retains its hardness after heating to 400°C and resists tarnishing above 300°C.
Our chrome purification plant ensures that our chrome vats deliver optimum performance at all times. This ensures the chrome solutions are always as new, resulting in superior chrome quality.
Heavy nickel deposits enable the reclamation of damaged, worn or incorrectly machined engineering components and impart chemical and high temperature resistance.
Nickel also forms an excellent seating for static fit bearings and eliminates fret corrosion while offering better performance than the original steel.
It may be used as a corrosion barrier beneath hard chrome deposits on components such as laminator cooling rolls, conductor rolls and duct rolls to prevent attack on the base materials through the micro-porous structure of the chromium. BEP can also nickel plate rolls with a softer more ductile grade specifically formulated for the machine engraving industry. After engraving and chrome plating these rolls are often used to apply chemically aggressive coatings onto packaging film.
All our nickel deposits can be turned and ground to customer specifications in our well equipped machine shop.
We have continued to develop our copper plating process techniques since 1970, designing and building our own equipment while striving for optimum performance and quality.
Today we boast extensive facilities for copper plating rolls of all sizes, from very large chill rolls and conductor rolls to large volume work for the printing industry. The copper produced in our vats is fine-grained and highly ductile. We use it to deposit thicknesses from a few microns to in excess of 20mm.
Although copper is relatively corrosion resistant it is subject to rapid tarnishing and staining if exposed to the atmosphere. Consequently, electro-deposited copper is rarely used unprotected and is normally overlaid with chrome or nickel.
Our manufacturing centre has the capability to machine and polish copper rollers down to very fine limits and to apply various textures prior to chrome plating.
