About Us


We Make Displays POP

Anfinsen has maintained a large presence in the Point-of-Purchase display industry for several decades now. While the industry services a wide range of end-point distributors, such as Wal-Mart, Walgreens, Gas Stations, Target, and other convenience stores, we work closely with many of the marketing and design firms behind the scenes for these time-senstive projects. Product design tends to require a lot more time and years of research and development, while retail displays (for those products) are the last thing to be considered before launch to market, and competitors are always trying to beat each other to the market. This industry has created a high demand for American manufactures like Anfinsen, due to time constraints, quality issues, and solving problems on the fly.



Many of our customers come to us because we have developed a sense of urgency over the years in a fast-paced and competitive market. We will help you complete any custom project from concept to mid or high-volume production, but we particularly excel when the pressure is on. We will quote your custom projects in with a sense of urgency and lay out a road map we feel is one of the best in the industries without sacrificing quality.



Anfinsen Plastic Molding was founded in 1935 and started with molding small size molded parts that were a result of technical limitations of that era. We have since advanced in to molding large scale parts with complex geometries and materials, as well as a full assembly warehouse to manage customer supplied materials, like hardware, metal, custom-packaging, and other polymer based goods to complete your finished product. With a full inventory barcoding system, we are capable of managing large-scale programs that need storage till fulfillment and then on to the next project.
