BLOW MOULDING

Crafting Complex Shapes with Precision Air

Blow Moulding

To produce hollow plastic parts, a highly efficient and precise manufacturing process is used called injection blow moulding. It is a process where you combine injection moulding along with blow moulding techniques. This process gives one the freedom to create products that are durable and light in weight. Moreover, this type of moulding process allows you both versatility in capacity and application hence, it is an ideal choice for manufacturing items of capacity from 50 ml containers to large 3000-litre tanks.

BUT HOW DOES INJECTION BLOW MOULDING ACTUALLY WORK?

Firstly, a small, test-tube-shaped piece of plastic goes through the process of injection moulding to turn it into a preform. Which is then heated and shifted to a blow moulding station. Following this, in the next step using pressurised air, that preform is inflated into the desired shape. Hence, as a result a seamless, hollow product with consistent wall thickness and excellent structural integrity is produced.

This is not it. Injection blow moulding has a lot more to know. In the large family of blow moulding, Injection blow moulding is part of the many techniques. And its subtypes are much more to look into. As each one of them is suited for a different application and product requirement. Come let’s blow your minds:

Extrusion Blow Moulding: High-Speed Precision for Large Projects

For producing hollow parts by extruding molten plastic into a tubular shape (parison) this type of process is ideal. This process inflates the molten plastic inside a mould to give it the form of a final product. It’s usually used to produce items like bottles, containers, and automotive parts. The process is highly versatile. It is capable of accommodating a wide range of shapes and sizes, making it a go-to method for large-scale production.

Continuous Extrusion Blow Moulding: Efficiency with Continuous Flow

To leverage the need of small to medium sized products this type of injection moulding is the best pick. It is high speed and it ensures continuous flow of materials too! Opting for this process also results in efficient and cost-effective manufacturing. In the production of packaging items like detergent bottles and small containers, this type of blow moulding process is taken into measure. The consistency in quality and lesser material wastage is observed in this process because of this nature of being continuous.

Rotating Wheel Moulding: Simultaneous Production for Large Parts

For products that are large, hollow and often circular in shape like barrels and water tanks, this blow moulding technique is usually opted. In this process the concept of rotating wheel allows manufacturing units for the simultaneous production of multiple items, hence increasing efficiency. For the manufacturing of products that require uniform wall thickness and high structural integrity, especially in larger dimensions it is a preferred method.

Injection Blow Moulding: Achieve Precision for Small to Medium Containers

For producing small to medium-sized containers with intricate designs and consistent wall thickness, this method offers unparalleled precision, making it the most ideal choice. Pharmaceutical and cosmetic industries for bottles and jars, this process turns out to be a perfect choice. The process ensures that each product is lightweight and durable, with smooth surfaces and detailed features.

Intermittent Extrusion Blow Moulding: Seamless Design Flexibility for Custom Creations

Intermittent the word says it all. Here, in this process it involves pausing the extrusion process. It is done to allow the creation of intricate details and complex geometry to form. Such type of moulding is often used for specialty items that are in need of detailed features or different wall thicknesses. For manufacturing custom made products this process offers flexibility of design and quantity.

Got Questions? We’ve Got Answers

Q1. What materials are used in blow moulding?

Answer: Blow moulding process involves shaping hollow plastic parts by inflating heated plastic into a moldd. The blow molding machine uses a variety of thermoplastics during the process. The common materials used are Polypropylene, Polyvinyl Chloride, Polyethylene, Polyethylene terephthalate, and Acrylonitrile butadiene styrene. However, the material choice depends on the product’s desired properties, such as strength, flexibility, or impact resistance.

Q2. Is blow moulding expensive?

Answer: The blow moulding process can be initially expensive due to the high cost of molds and blow molding equipment. However, once the molds are created, the production costs significantly decrease, making large-scale manufacturing more cost-effective. Although, blow moulding companies and blow mold manufacturers often balance the setup costs by setting up with long-term production efficiency, especially when producing large volumes. The upfront cost is high, but the process eventually becomes inexpensive over time.

Q3. What is the plastic blow molding process?

Answer: The plastic blow molding process involves heating a plastic tube to its certain melting point to create a component. The molten plastic is then put into the hollow mold in order to create the required part.

Q4. What are the common blow molding equipment?

Answer: Some of the common blow molding equipment include:

Injection Blow Molding Machines

Extrusion Blow Molding Machines

Continuous Blow Molding Machines

Injection Stretch Blow Molding Machines

Q5. What is the blow moulding process?

Answer: Blow moulding is a manufacturing process used for converting thermoplastics into hollow objects. This process is followed for industrial applications and food containers, cosmetic products, beverages, and pharmaceuticals.

Q6. What are the 4 stages of blow moulding?

Answer: A blow moulding products manufacturer follows these 4 stages:

Plastic melting and extrusion

Mold clamping

Blowing air

Cooling and ejection

TWO-STAGE INJECTION STRETCH BLOW MOULDING

SINGLE STAGE MACHINE

In this process, the single stage signifies that the preform and the final product are made within the same machine. This technique helps in streamlining production and reducing handling time. Hence, it turns out to be a highly efficient process. It is an ideal pick for producing high-quality bottles with excellent clarity and strength, commonly used in the beverage industry. To produce products of light weight and supreme quality, this technique is the best choice.

DOUBLE STAGE MACHINE

Process Stage 1st

Double stage means the preform is created in one stage and the final product in another.

Process Stage 2nd

It is then reheated and moulded into the final product in the second stage. This process offers greater control over the material to be moulded and the final shape as well. Therefore, this process is ideal for making complex designs and higher production volumes. Particularly for beverages and personal care products, where there is demand for high quality bottles in larger batches, this process is preferred.

MATERIALS USED IN INJECTION BLOW MOULDING

To determine the properties of the final product, choice of material is a crucial factor. Injection blow moulding can be applied in a wide range of materials, each offering distinct application in various industry:

– Polyethylene (PE):

High-density Polyethylene (HDPE): This material holds the property of being strong and impact-resistant, hence making it ideal for fuel tanks, air ducts, sprayer tanks, conduit, and bottles.

Low-density Polyethylene (LDPE): It is flexible and lightweight in nature, hence suitable for toys, household containers, sporting goods, and IV bags.

– Polyethylene Terephthalate (PET): It holds the property of strength and is clear in nature, so it is perfect for manufacturing water bottles, medical bottles, jars, and specimen containers.

– Polypropylene (PP): Resistant to chemicals and heat, used for toys, lab equipment, feed troughs, and custom packaging.

– Polyvinyl Chloride (PVC): Durable and versatile, often used for air intake manifolds, canisters, and industrial containers.

– Nylon or Polyamide (PA):

Tough and wear-resistant in nature, hence commonly used in producing engine components and bumper components.

– Polycarbonate (PC): Has the capability to high impact resistance and clarity, ideal for medical bottles and lab equipment.

– Copolyester: It offers clarity and chemical resistance in its characteristics, so it is used in pharmaceutical containers and water bottles.

– Cyclic Olefin Copolymer (COC): High transparency and dimensional stability, used in test tubes and specimen containers.

– Acrylonitrile Butadiene Styrene (ABS): Strong and lightweight, used in furniture components like chair bases and table legs.
