Method of Manufacturing Architectural Components

摘要

A method of forming architectural trim from cellular polyvinylchloride. The process employs manufacturing dimensionalized cellular PVC architectural components from sheet goods that can achieve both linear and radius shapes without using heat bending techniques. The process strengthens the cellular PVC giving it more structural integrity than other products made strictly of cellular PVC. These techniques enable the manufacture of components with tighter tolerances than traditional heat bending techniques which distort the size and shape of the material which make accurate and precise assembly difficult.

主权项

1. A method of forming architectural trim comprising:
drawing a left side member having at least one contoured mounting surface on a computer aided design (“CAD”) system using guidelines and machining layers; drawing a right side member having at least one contoured mounting surface on the CAD system using guidelines and machining layers; drawing a front member having a left mounting surface, a right mounting surface, an outer face, an inner face, with a thickness between said outer face and said inner face, on the CAD system using guidelines and machining layers, said inner face containing at least one region where said thickness of said front member will decrease allowing said front member to bend conjugate to said left side member and said right side member; importing said CAD drawings of said trim members in a computer aided design/computer aided manufacturing (“CAD/CAM”) software and applying machining styles specific to layers of said CAD drawing; outputting numerical control (“NC”) code to a computer numerical control (“CNC”) router; operating said CNC router for machining said trim members from a material, said material containing plastic; assembling said trim members into said architectural trim using an adhesive; priming said assembled architectural trim with a primer; painting said assembled architectural trim; and installing said assembled architectural trim onto a building exterior.
