Blow Molding Machine

What is a blow molding machine

A blow molding machine is a specialized device that uses air pressure to shape molten plastic into a hollow product. Its working principle is to first melt the plastic resin and then inject it into the mold. Then, compressed air is introduced to expand the plastic and fit the shape of the mold. This process can create a variety of products of different shapes, sizes, and thicknesses. This technology is widely used in the production of bottles, cans, and other plastic products of complex shapes.

Classification of blow molding machines

1. Extrusion blow molding machines: These machines use a continuous extrusion process to form a parison, which is then blown up and cooled to make the final product. They are suitable for mass production of simple-shaped products such as bottles and containers.

2. Injection blow molding machine: This type of machine combines the injection molding and blow molding processes. First, a preform is injection molded and then transferred to a blow mold, where it is blown up to form the final product. Injection blow molding is very suitable for producing complex shapes with high precision.

3.Injection molding machine: Injection molding machine：it is the main molding equipment for plastic products of various shapes made of thermoplastics or thermosetting plastics using plastic molding molds. Its working principle is to heat and melt the plastic particles, inject the molten plastic into the mold cavity through the injection device, and obtain the desired plastic products after cooling and solidification. Injection molding machines are widely used in many industries such as automobiles, electronics, home appliances, medical, packaging, etc.

What products can blow molding machines make

Blow molding machines can produce a variety of products, including:

1. Beverage bottles: used to package water, soft drinks, juices and other beverages.

2. Containers: used to store food, chemicals, cosmetics and other products.

3. Toys: such as balls, dolls and action figures.

4. Auto parts: fuel tanks, air ducts and other parts.

5. Industrial products: barrels, drums and pallets.

What materials can blow molding machines make

1. PE: often used to make bottles and containers due to its flexibility and durability.

2. HDPE: 70% blow molding barrels, large blow molding applications, such as lubricant bottles, detergent bottles, chemical bottles, large chemical barrels, medical bed boards, outdoor tables and chairs, lifebuoys, insulation barrels, children's outdoor amusement, rocking horses, tool boxes and bags

3. LDPE: eye drops, ocean balls, seasoning bottles

4.PP: has good chemical resistance and is suitable for packaging various products.

5.PET: Due to its transparency and strength, it is widely used in beverage bottles.

6. PC: Blow molding: 5-gallon buckets

7. PETG: High transparency, relatively hard, generally used for cosmetic bottles, disinfectants, large outdoor water bottles

8. PVC: used to make pipes, fittings and some packaging materials.

9. Nylon: used to produce high-performance products such as fuel tanks and air ducts.
