Materials used making the Husqvarna Viking 2000 sewing machine and power gear
Most of the small details (parts) of the sewing machine are made of steel or steel alloys with different grades of tempering. However, quite a lot of the details in the mechanisms are made of die-cast aluminum. In addition, here are some details which must have good bearing properties and wear resistance, which are made of different sorts of plastic. On the subject of plastic, it is important to distinguish between the type of plastic used in design details and the type used for inexpensive packing and throw-away wrappings. The constructional plastics have completely different properties and are considerably more expensive. If a detail, e.g., a cog wheel or a programmer, is made of plastic, it must have advantages over metal – e.g., a cog gear will function more smoothly 20 and quietly; a cog gear or programmer will have more wear resistance. If the Husqvarna viking 2000 sewing machine power gear is made of metal it will wear much quicker, even when using the best special steel, as long as the properties are not changed completely by means of an 0il bath or the like.
