DESIGN ENGINEERING. A pre-production model

The Pre-production model produce in an experimental workshop on working drawings according to a plan of the designer. It is a prototype of a new product and is intended for the general is art-design estimation and test for conformity of a product to functional requirements. For all-round operational tests produce it is a little exemplary. The sample carry out from the materials provided for mass production, and finish according to the project.

Replacement of materials without the coordination with the author, their imitation, change of furnish, a structure and the invoice can lead to distortion of idea of the project, lower constructive and aesthetic advantages of a product.

In the course of performance of a pre-production model the designer takes active part, conducts architectural supervision. It supervises and demands from quality executors of manufacturing of the sample. At operational development of the sample specifications and changes of constructive knots, sections, furnish, etc.

Manufacturing techniques it is exemplary as much as possible comes nearer to technology under production conditions taking into account real possibilities of an experimental workshop. The time industrial equipment calculated on manufacturing of a small lot of products is applied. Designs on the basis of plastics can be formed on plaster moulds and forms on the basis of wood or fibreglasses. Modes choose proceeding from concrete conditions and possibilities.
