Manufacturing
When
manufacturing a part that is hollow in shape, blow molding is the most cost
effective manufacturing process. Blow molding is accomplished by extruding a
hollow sleeve (or parison) of molten plastic between two mold halves. The mold
is then closed around the parison and air is injected within, forcing the
plastic to mimic the mold cavity configuration.
Dove
Plastics has blow molding machines with single and dual heads ranging in shot
size from 1/2 oz. to 10 lbs.
Advantages
of Blow Molding:
- Tooling
cost is typically less than injection molding.
- Piece
price is typically less than rotational molding.
- One
piece construction (no welding or gluing part halves together.)
- No
cores allow for irregular shapes.
- Seamless
construction is ideal for liquid filled or airtight containers.
- Excellent
ESCR (Environmental Stress Crack Resistance.)
- Quick
product revisions allow for increased flexibility
- (wall
change is process change, not a tooling change. Tools made from aluminum are
less costly to revise.)
