A building's surface detailing, inside and outside, often includes decorative moulding, and these often contain ogee-shaped profiles—consisting (from low to high) of a concave arc flowing into a convex arc, with vertical ends; if the lower curve is convex and higher one concave, this is known as a Roman ogee, although frequently the terms are used interchangeably and for a variety of other ...
Use of simulation in the design phase can help to reduce problems with the physical mould and therefore reduce time to market, reduce the use of material and energy, prevent surface defects such as sink and flow marks, and reduce the time taken to inject, cool and eject the part, improving the injection moulding machine's output rate.

Other varieties of concave moulding are the scotia and congé and other convex mouldings the echinus, the torus and the astragal. Placing an ovolo directly above a cavetto forms a smooth s-shaped curve with vertical ends that is called an ogee or cyma reversa moulding. Its shadow appears as a band light at the top and bottom but dark in the ...
The quarter-round cross-sectional profile of the fundamental design element, the ovolo, in an unadorned molding, showing also with its resulting shadow pattern. Ovolo is an Italian word that means "little egg". [1] The ovolo or echinus is a convex decorative molding profile used in architectural ornamentation. Its profile is a quarter to a half ...
Brothers Henry Dunn Wickes and Edward Noyes Wickes moved to Flint, Michigan, from New York in 1854, becoming involved in the area's lumber industry.The brothers, along with partner H.W. Wood, later established Genesee Iron Works, a foundry and machine shop; after buying out Wood, the business was renamed Wickes Bros. Iron Works and moved to Saginaw, Michigan, to be closer to a source of pig iron.
In woodworking, a moulding plane (molding plane in US spelling) is a specialised plane used for making the complex shapes found in wooden mouldings. [ 1 ] Traditionally, moulding planes were blocks of wear resistant hardwood, often beech or maple , which were worked to the shape of the intended moulding.
These machines vary in size between small to medium compared to other rotational machines. Vertical rotational molding machines are energy-efficient, owing to the compactness of their heating and cooling chambers. These machines have the same (or similar) capabilities as the horizontal carousel multi-arm machines, but take up much less space. [8]
Compared to conventional injection molding, thin wall molding requires molding machines that are designed and built to withstand higher stresses and injection pressures. The molding machines computer control should also be precise in order to make quality parts. For this reason these molding machines are more expensive than general purpose ...
