Patented composite plating technology

The most dependable PEEK and Ultem® plating technology.

The idea behind GreenPOP has never wavered: to provide the ultimate metal coating on a plastic surface. This proven technology works at scale. The best adhesion, paired with high-performance thermal shock strength — all within an incredibly smooth coating. Our revolutionary PEEK and Ultem® processes deliver such spectacular surface quality that even the smallest details of your part are perfectly preserved. GreenPOP is the most dependable plating on plastic solution with over 98% production yields.



A patent-pending adhesional pre-treatment and novel metallizing technology jointly developed by the Center for Physical Sciences and Technology in Lithuania (EU) and Alliance Finishing & Manufacturing (USA) is being used to plate production lots of high glass (Tg) transition temperature plastic components. This revolutionary technology, for the first time, completely eliminates any toxic chrome based acid etchants, the need for abrasive blasting, or organic solvents currently used to plate plastics like PEI (Ultem®), PEEK, Nylon and others.

What if your plated composite parts didn’t require toxic heavy metal acids, abrasive blasting or solvents to sensitize them prior to metallization?

Alliance Finishing & Manufacturing is the only company to offer this kind of plating technology. 

GreenPOP pre-treated plastic parts can be either metallized by conventional electroless metallization involving palladium (Pd) and copper (Cu) or by direct electroplating techniques. 


A cost effective solution with exceptional adhesion properties 

Why is GreenPOP better?

Metallization can be done exclusively by direct electroplating methods, which offer exceptional adhesion properties on the primary plated layer of the coated part, as compared to the same part metallized electrolessly. Components made from PEI resins (e.g. Ultem®) and PEEK can be plated less expensively by eliminating the need for conventional electroless metallization that uses precious metals and formaldehyde based electroless copper for activation and metallization.

Unmatched thermal shock stability

GreenPOP has exceptional thermal shock stability and meets or exceeds the thermal shock requirements of MIL-DTL-38999 for composite plated connectors.

Incredibly smooth parts that maintain dimensional stability 

Medical composite components using GreenPOP plated parts come out exceptionally smooth and maintain their dimensional stability.  Compare this to conventional techniques that utilize combinations of abrasive blasting, along with heavy metal acid etchers  prior to electroless metallization that produce rougher and cosmetically less appealing parts. Additionally, delicate or highly cosmetic plastic parts manufactured in their “as molded” or “machined” condition maintain their exceptional aesthetic qualities when metallized and electroplated with GreenPOP technology.

GreenPOP plating adheres despite extreme temperatures

The part on the right cracked when it was subjected to extreme temperatures above 500F. Here you can clearly see where the plastic part deformed and split while the plating continues to adhere to the part’s surface.
