Consistently high, uniform quality standards are required in many areas of industry. Electroplated surfaces are in use nearly everywhere and represent a reliable corrosion protection system. However: worldwide there are many companies offering this technology as individual products, from small firms to major chemical companies. And this is where the problem of fluctuating quality lies. Electroplating - The principle DÖRKEN is addressing this challenge and responding with a system: the galvanic protection system DELTA-​PROZINC®. This is a process-safe, highly-efficient and non-hazardous electroplating system with superb corrosion protection and screw fitting properties. System means that it is not just a collection of random products from diverse manufacturers. Instead it is a complete system, comprising products tailored to one another in an individually customised, resource-saving procedure with selected licensees. This results in uniform global quality standards that ideally satisfy the high requirements of the car industry. The overall package of pre-treatment products, zinc baths, passivation and seals is also ecologically sustainable, as it dispenses with the need for nickel. For threaded parts, sealants can be adjusted to the coefficients of friction requirement of parts manufacturers or customers via integrated lubricant additives. Further requirements (such as colouring) can also be met where necessary. Individual requirements, individual solutions Each customer has a different focal point for requirements. DÖRKEN helps you to recognise these and reflect them in a perfectly-harmonised combination of plant and galvanic products.
