The manufacturer who makes the molds is called the moldmaker. Manufacturing is the use of machines, tools and labor to make things for use or sale. Also it can be used for selling things. A release agent is typically used to make removal of the hardened/set substance from the mold easier. The terminology can depend on the application. Molding or moulding is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a pattern. Sand casting involves both a "pattern" (which is the positive-image model of the desired part) and a "mold" (which is the negative-image hole made by packing sand around the pattern). The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. A mold is the opposite of a cast. A mold or mould is a hollowed-out block that is filled with a liquid like plastic, glass, metal, or ceramic raw materials.

|Injection Molding Книга по Требованию Frederic P. M. |
After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part.

|Mold-Metal Reactions in Magnesium Investment Castings. A Quantitative Study Книга по Требованию Celal C. |
Magnesium, however, reacts practically with all investment casting refractories, from which molds are made of. The research work was carried out a) to investigate the degree of reactions between the various refractory materials and the magnesium alloy AZ91E; b)to find new techniques to reduce these reactions and c)to provide a better understanding of the mold-metal reactions in magnesium investment casting Fused alumina,fused silica, molochite,zircon, yttria, zirconia and fused magnesia were the studied ceramics. Results of the experiments are discussed and conclusions are drawn on the relative reaction tendency of studied refractories and other factors affecting the mold-metal reactions. All known casting processes including investment casting can be used for production of magnesium castings. Use of magnesium in industry, particularly in automobile industry is consistently increasing.
|Wrexham, Mold and Connah's Quay Railway Книга по Требованию Lambert M. S. |
The Wrexham, Mold and Connah' s Quay Railway (WMCQR) was incorporated on 7 August 1862 to build a line from Wrexham to Buckley. The Buckley Railway had already been incorporated on 14 June 1860 to build a 5-mile (8 km) line from that town to a junction with the London and North Western Railway Chester-Holyhead main line at Connah' s Quay in order to link collieries and brickworks in the area with a point of shipment on the River Dee.
