Blow molding is a type of manufacturing method which uses a custom mold to form hollow plastic pieces. The molded plastic forms a vessel which can protect goods while in transit, because it has been shaped to the exact size and shape that the goods will need while in route. There are several advantages to using blow molding, although there are some disadvantages as well.
- Reduces Costs
- Manufacturers can create more varied and intricate designs
- Difficult to mold in-holes
- Cost rises as size increases
- Lets companies meet consumer design for variations in plasticware
- Quick manufacturing time with high volume outputs
- Permits new designs for everything from fuel tanks to toy wheels
- Lower pressure during production reduces manufacturing costs
- Has several methods of production including extrusion and injection. Injection and Injection stretch methods use a preform whereas extrusion melts the plastic into a rounded parison, which is then removed from the furnace, attached to a mold, and compression air is blown to form an exact match.
- Can be automated
- Lower machinery and tool costs
- No wasted material, all leftovers can be reused or recycled
