Blowing Machine

A blowing machine is a device used to produce hollow plastic products by inflating a molten plastic preform or parison within a mold. The process is commonly known as blow molding. These machines are integral to the mass production of a wide variety of containers and objects.

Materials

Blowing machines work with a range of thermoplastic polymers, including:

• Polyethylene (PE): High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE) are frequently used for bottles, containers, and films.
• Polypropylene (PP): Known for its high chemical resistance, PP is used in containers for detergents, chemicals, and food packaging.
• Polyethylene Terephthalate (PET): Commonly used for beverage bottles, food jars, and cosmetic containers due to its clarity and strength.
• Polyvinyl Chloride (PVC): Used for industrial applications, medical containers, and rigid packaging.
• Other Thermoplastics: Polystyrene (PS), Polycarbonate (PC), and others can also be processed depending on the machine's capabilities.

Purpose

The primary purpose of a blowing machine is to efficiently create hollow plastic products with consistent shape, size, and wall thickness. This process is significantly faster and more cost-effective than other methods for producing large quantities of hollow items.

Function

The blow molding process generally involves these steps:

1. Preform/Parison Creation: A plastic material is heated and formed into either a preform (a small, thick-walled tube with a screw cap finish – used in PET blow molding) or a parison (a hollow tube – used in other blow molding types).
2. Mold Clamping: The preform or parison is placed between two mold halves, which are then securely clamped together.
3. Inflation: Compressed air is injected into the preform/parison, forcing it to expand and conform to the shape of the mold cavity.
4. Cooling & Solidification: The plastic cools and solidifies within the mold.
5. Ejection: The mold opens, and the finished plastic product is ejected.
6. Trimming (if necessary): Excess plastic (flash) may be trimmed from the product.

Usage Scenarios

Blowing machines are used in numerous industries, including:

• Packaging: Production of bottles for beverages (water, soda, juice), detergents, cosmetics, pharmaceuticals, and food.
• Automotive: Manufacturing of fuel tanks, air ducts, and other hollow components.
• Industrial: Creation of containers for chemicals, lubricants, and other industrial fluids.
• Household Products: Production of toys, garden equipment, and other plastic items.
• Medical: Manufacturing of bottles, containers, and other medical devices.

Common Types

Several types of blowing machines exist, each suited for different materials, product sizes, and production volumes:

• Extrusion Blow Molding: A parison is created by extruding molten plastic, then inflated within a mold. Suitable for a wide range of shapes and sizes, particularly larger containers.
• Injection Blow Molding: A preform is created by injection molding, then inflated within a mold. Ideal for producing small, precision parts with tight tolerances.
• Stretch Blow Molding: A preform is stretched both axially and radially during inflation, resulting in higher strength and clarity. Commonly used for PET beverage bottles. There are variations including single-stage and two-stage stretch blow molding.
• Co-extrusion Blow Molding: Multiple layers of different plastic materials are extruded simultaneously to create containers with barrier properties or aesthetic effects.
• Rotational Molding: A mold is rotated while heated, allowing plastic to coat the interior surface. Used for producing large, hollow, seamless parts.
