PAGE 2 (Cont’d from p. 1) but the loss of the company facilities as well, as the large customer had been providing facili- ties for the plastic injection molding operation for its own convenience. The company has not only survived but has success- fully expanded its business through utilizing its internal strengths to provide exceptional customer service that competitors find difficult to duplicate. As a family busi- ness, father Jim McCall has a strong process and op- erations background working with Whirlpool Corpora- tion in Michigan after receiving a master’s degree in engineering from the University of Michigan. Son, J. McCall, has a strong plastic materials background with a degree from Western Washington University. To- gether, they are in a position to not only offer manufac- turing services but custom engineering development and materials selection advice to customers who need this kind of process development assistance to take parts from prints in the design stage and turn them into reality. They have locked in customer relationships notFigure 3 — SME Chapter 248 members listen as owners Jim and Jay only by being a manufacturing source for plastic moldedMcCall explain their operation as well as the basic principles involved products, but by also being a design and engineeringin transforming thermoplastic granular feedstock used as the basic raw resource to customers who have new product in thematerial into molded products by carefully controlled heat and pressure formative stage. They are especially adept at assisting customers in modifying or tweaking original designs in such a way to make actual production operations more practical, feasible and cost efficient. As an example of this, Jim McCall, explained an espe- cially challenging design and operational problem the company had been faced with recently involving “puffer nozzles”. This molded component is part of a sophisti- cated quality assurance system used in the food and produce industry. As items are passed down the length of an inspection conveyor they are analyzed by an opti- cal/video system which can identify defective or non- conforming items. Once an identification has been made the system will remove the offending item from the production stream by actuating the “puffer nozzle” which then directs a “puff” or “blast” of high velocity air at the defective piece as it comes off the conveyor, seg- regating it from acceptable product. The “puffer noz- zle” is a challenging product for the plastic injection molding process where products are typically designed with a specific taper to promote ease of ejection from the mold at the end of the injection cycle. On this partFigure 4 — Plastic Injection Molding cell at Reiff Injection Molding the internal orifice had to be designed with a taper op-Inc., plant tour attendees watch as Jim and J.

Reiff Injection Molding —Success from extensive process technology knowledge coupled with customer need anticipation PAGE 3 Customer Service: The other weapon in Reiff’s arsenal is customer service that goes the extra mile after the parts have moved from the design stage and into production stage. Marilyn McCall manages office operations and closely monitors customer needs. The company has developed such close relationships with customers that it provides what the Wall Street Journal has re- cently described as the next level of customer service — not just meeting customer needs and desires, but in some cases — anticipating them. The company has also carved out a special niche strategy in that it avoids becoming a com- modity supplier, but focuses its attention on cus- tomers who need the kind of quick response for shorter runs of parts that have become Reiff’s specialty. The company has also recently ac- quired marketing rights to one of its major prod- uct lines “The Gripper Caddy” (shown in the pic-Figure 5 — J.

Plant Tours: cross-pollination opportunities: SME and SME chapters have a strong tradition of arranging plant tours for members to view opera- tions in a wide cross section of industry and busi- ness. Recently this concept was taken to the next level when SME arranged for COLLABORATE 2006 an event designed to draw attendees from across industry to share ideas on everything from new manufacturing techniques to lean implemen- tation. Participants included representatives from Toyota, Daimler, Lockheed, Northrop, Ford, the Army and others. In addition to attending technical and networking sessions, pLant tours of Siemens Electronics and Boeing Delta RocketFigure 6 — The plastic injection molding cell at Reiff Molding includes four assembly facilities were offered.different injection molding machines of varying capacities.
