Engineering II

 

 Where are patterns and developments used? 

 

Sheet metal industry

     a. Many metal objects are made from sheet of metal that are laid out, cut, and formed into required shapes and fastened together.

 

 

 

 

 

 

 

 

 

 

           i) Shaped by bending, folding, die stamping or rolling.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

           ii) Fastened by riveting, seaming, soldering, or welding.

Packaging industry

     a. Packaging is a very large industry that uses pattern development.

 

 

 

 

 

 

 

 

 

 

 

 

 

     b. Both engineering and artistic skill are needed when creating packages, because each package design must meet many requirements.

           i) To protect the contents during shipping of fragile objects.

           ii) Be attractive for sales appeal.

           iii) For durability—some packages are meant to be used for a short time then thrown away, others are made to last a long time.

 

 

     c. Designers use many different materials and varying thickness.

           i) Thin or medium –thick stock paper. This material can be folded easily for items like boxes; others may need glue on their tabs. For example: book covers, envelopes, juice cartons and paper cups.

           ii) Cardboard, corrugated board and other materials require an allowance for thickness. For example: boxes that have a separate cover or boxes made of two parts that slide together.
