Industries with demanding requirements.
Each sector places different demands on its parts. We show where each one works and how we protect it.
AutomotiveVisible finishes, series production.
Bumpers and wheel bolts are part of a vehicle's exterior finish and must retain their appearance throughout their service life.
Rain, washing, dirt and continuous use put the coating to the test. A difference in brightness is noticeable on the finished vehicle, and a failure of protection can lead to visible corrosion.
That is why we apply the triplex nickel chrome plating system, which combines corrosion protection with a bright, uniform decorative finish. The process runs on an automatic line that repeats the same cycle for every part.

Oil and gasThreaded connections that withstand assembly.
In oil and gas wells, pipes are joined by threaded connections and couplings, tightened to specified torques and operating at great depths.
When a thread works steel against steel, the thread profiles can adhere to and tear material from each other: this is galling, a failure that can compromise the connection.
That is why we treat the thread surface: manganese phosphating retains lubricant and helps reduce metal-to-metal contact, while copper plating provides an anti-galling surface. The applicable treatment is defined by each part's specification.
1986 The oil industry has been part of Dro Pur since its earliest developments. Today, the company is a TenarisHydril-approved supplier for copper plating and manganese phosphating.

Agriculture and miningEquipment working under load and exposed to the weather.
Agricultural machinery and mining equipment operate under heavy loads, dust, moisture and long cycles, often far from a workshop.
Gears, transmissions, fasteners and threads are subject to wear and corrosion, especially during maintenance and disassembly.
That is why we want to bring our experience in phosphating, copper plating and chrome plating to these industries, assessing which treatment best meets each component's demands and can provide greater protection, durability and performance.
