located on 6-in. centers. In another instance, a manufacturer of sensors located in the Midwest needed to expand their production capacity. A conveyorized mold drying oven with a production rate of 3,000 lbs. per hour provided an effective solution to increase their production rate. Te company processed two dif- ferent molds with different heating times. Mold A required a 45-minute drying time and mold B required 22.5 minutes. Based on the part size and production rate, an oven heated length of 24 ft. was necessary to achieve 45

minutes of heating, and a 12 ft. length was sufficient for 22.5 minutes of heating. Traditional conveyor ovens use a conveyor belt running through the oven chamber, whereby all the molds running through the oven at the same time are exposed to the heat for the same duration. Since they all ride on the same conveyor belt, traditional oven designs prohibit different heating times for different molds being run through the oven at the same time. In order to provide different heating times for the two differ- ent molds types, Wisconsin Oven

provided a unique bi-directional dual conveyor oven (Fig. 2). The mold drying oven utilizes two indepen- dently powered belt conveyors, each with its own drive system and speed control. Additionally, they run in op- posite directions. After mold A exits conveyor #1, the operator places it on conveyor #2 to travel back through the oven to achieve the entire 45 minute drying time. When the B molds exit the oven, they are re- moved from the conveyor, since they had completed their 22.5 minute drying time.

safety training. Whether visitors to a facility or new employees, the need for clear safety instruction is essen- tial. Beyond the basic issue of com-

munication, everybody is dealing with a multi-lingual workforce and society. This requires instructional materials to be accommodating to these conditions. Second are concerns that the

cost of training and operations for staff is out of control. This includes operational training for equip- ment, plant procedures and product assembly. Is there a better way to instruct customers on the use, instal- lation, maintenance or assembly of products?

This was the question when Turis

Turis Systems animated a video for Neenah Foundry to show about plant safety. 44 | MODERN CASTING October 2016

Systems (Madison, Wisconsin) talk- ed to Neenah Foundry. Turis showed Neenah (Neenah, Wisconsin) a safety animation it had developed for the construction industry and was surprised to discover Neenah had already been thinking along these lines. Neenah’s main source for train- ing documentation was a series of “Safety Alerts” put together in individual Word documents with images and text. While comprehen- sive in covering the necessary safety information, Neenah recognized the challenges its current documenta- tion faced in communicating critical safety information. This format depends on people thoroughly reading the materials. Another challenge was that the topic, while critical, is not necessarily all that interesting and the documents were not very engaging visually. While
