8 BASIC FACTS ABOUT BLOW MOLDING Do you know what blow molding is?
1. What is blow molding? • Blow molding is a manufacturing process that makes it possible for hollow plastic parts to be formed. • In very basic terms, plastic is melted down, clamped into a mold, and then air is blown into it. All types of hollow plastic parts can be made through this process.
2. What are the types of blow molding? • There are different types of blow molding methods because some methods are more effective for certain parts, whether due to the shape or number of parts. • The following four slides explain the different types of blow molding methods: • Extrusion blow molding • Injection blow molding • Stretch blow molding • Reheat and blow molding
3. Extrusion blow molding. • In extrusion blow molding, a hot tube of plastic material is dropped from an extruder and captured in a water cooled mold. Once the mold is closed, air is injected through the top of the container. • When the hot plastic blows up and the mold material freezes, it’s able to maintain its shape.
4. Injection blow molding. • In this method, hot plastic material is injected into the part of the mold that creates the neck. The injected material is then taken to the next station on the machine where it is blown up into the finished container like in the extrusion blow molding process.
5. Stretch blow molding. • This method is mostly used for producing bottles commonly used for water, juice, and other similar products. • The injection stretch blow molding machinery molds a preform, which is then transferred to another station where it is blown and then ejected from the machine.
6. Reheat and blow molding. • This is a type of stretch blow process in which a preform is injection molded by an outside vendor. • There are many companies who produce these stock preforms on a commercial basis. • Factories buy the preforms and put them into a machine that reheats them so they can be blown. Preforms
7. What are the advantages of blow molding? • Here are just a few advantages of blow molding: • Less time spent on the mold-creation process • Faster turn-around times by a blow molding company • Well suited for high production rates using a variety of materials • Blow molding tools are fairly inexpensive compared to other molding equipment
8. Who offers blow molding services? • There are blow molding companies, such as Streamline Blow Molding, that offer blow molding services to businesses who need to produce hollow plastic parts. • It’s smart to work with a blow molding company because such a company will have the equipment and manpower to create exceptional blow molded products.
