Hollow blow molding involves placing a heated and softened plastic preform into a mold, then injecting gas to expand it into the desired shape. The entire process includes steps such as plastic melting, molding, cooling, and demolding. The advantages of hollow blow molding are low cost, high production efficiency, and ease in manufacturing complex shapes.
Hollow blow molding can produce a variety of plastic containers and parts, such as bottles, cans, drums, toys, etc. As the manufacturing of plastic containers can meet the needs of different industries, hollow blow molding has gradually become an important technology in the plastic products manufacturing industry. The use of hollow blow molding plastic containers is very widespread in industries such as food.
Common Blow Molding Products:
Hollow Blowing Bottles: Hollow blowing bottles are among the common plastic containers, widely used in industries such as food, beverages, oils, and detergents. They feature high transparency, light weight, good sealing properties, and safety and hygiene.
2. Hollow Blowing Barrels: Hollow blowing barrels are large containers used for storing and transporting liquids, widely applied in industries such as chemicals, oil, and food. They boast advantages like corrosion resistance, wear resistance, and high-temperature tolerance.
3. Hollow Blown Bottles: Hollow blown bottles are suitable for storing powders, granules, and other solid materials. They feature moisture-proof, insect-proof, and good sealing properties, and are widely used in industries such as chemicals and food.
4. Hollow Blown Toys: Hollow blown toys are lightweight, portable, and easy to carry children's playthings. Due to their smooth surface, non-toxic, odorless, and radiation-free features, they are greatly favored by both parents and children.
In summary, hollow blow molding can produce a variety of plastic shapes, including containers and parts. With the continuous advancement of technology, hollow blow molding will find applications in more fields.
