Foundry Molding: Intermediate comprehends various diverse practical and visual skills with knowledge of specialized materials and techniques. A foundry is a workshop that produces metal castings. Molds may be produced by a mix of molding sand with a binding agent (such as bentonite clay or chemical resins) formed in metal or wooden flasks using patterns attached to molding machines. These may also be formed manually especially if these are large molds, using sand rammers to compact the molding sand. Cores are produced using sand mixed with core binders compacted into core boxes and cured with heat or catalyst to harden into the required shape. The cores formed using different binders are finished and painted with coatings of graphite or refractory. Cores are set in the molds before it is closed and prepared for pouring. In most cases the molders pour metal into the molds they produced. This book will introduce the knowledge and skills for those studying and/or working in foundry industry to interpret and convey information in response to workplace requirements.


About this Book


The information in this book consists of basic to core competencies that a person must achieve to be able to produce all types of molds and cores using different kinds of binders and sand. He may produce the molds or cores manually or he may use molding machines and core making machines. This book covers all specifications interpreted from drawings, technical sketches and/or customer requirements.


About the Foundry Industry


The foundry industry consists of many stages from mining to the actual casting of the metal and iron. While most of the materials used in the foundry industry are mined from the earth as ore and minerals that are heated and liquified, many recycled iron and steel products are also heated and liquidated before being poured into molds and turned into new steel and iron bars. This type of recycling brings scrap yards, automobile salvage yards and neighborhood recycling programs into the foundry industry. Trucking and rail services are also involved in the process of creating new steel from old and discarded steel scrap, as they transport the raw materials to the foundry where the scrap is turned into new steel.


While the foundry industry is not responsible for the creation of many finished items, it is responsible for creating the raw castings that are finished by other factories. Once the raw materials have been heated to a liquid and poured into molds, the foundry industry process often requires use of large drop-hammers to pound the hot iron bars into a specific size and shape. Many different steel types and iron types are created by the mixture and addition of certain minerals to the molten iron while it is still in the large cauldrons. Engineering firms have a construction crew or hire a construction company to build the foundry. Engineers work with construction foremen to plan and construct the facility from start to finish. Foundry engineers look at the current setup and structure and determine solutions to meet the customer’s needs within the current facility.
