Major Bank Uses Reaction Injection Molding Parts in Branch Re-Branding Effort

When two large regional banks merged and management decided to re-brand the 2,300 new branches, Exothermic Molding Inc. was chosen as a key supplier. The focal point of the new branches was a large branded Financial Merchandising kiosk, designed by a well known Brand Management Design Firm, and an Express Deposit Box. The sizable display, approximately 7 feet wide by 7 feet high, posed many design and manufacturing challenges.

Designers wanted a monolithic "solid" look with no reveal lines. The free standing display required full 360 degrees visibility, complex geometry, and structural integrity. Accuracy and repeatability of the parts were also crucial. Since the unit had to ship to 2,300 branches and be assembled on site, lightweight materials were preferred. The Express Deposit Box needed to provide security of contents, and support a heavy work surface made of glass and stainless steel.

Initially, the design called for parts to be made from fiberglass. However, the manufacturing process produced parts that were inaccurate, very heavy, and expensive. In addition, fiberglass production was too slow to keep up with the synchronized grand opening of 2,300 branches throughout the East Coast.

Exothermic met the challenge with the Reaction Injection Molding process. Low cost "hybrid" cast aluminum molds were designed and fabricated in just 5 weeks, allowing the client to quickly implement the affordable plan for RIM molded parts. Cost efficiency was maximized by creating modular molds the could be used to produce two different lengths. In addition to the accuracy and repeatability provided by the Reaction Injection Molding process, RIM parts also finish extremely well. Exothermic Molding was responsible for the final painting, decal application, mechanical assembly, and packaging of all parts.

The Reaction Injection Molding process was selected from numerous alternatives including fiberglass and several thermoplastic processes. Reaction Injection Molding's benefits, such as low costs, short lead times, the ability to produce large parts, superior part-to-part consistency, and excellent finishing, proved to be the perfect combination for this program.
