Blow moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube until it forms the desired shape.
There are three main types of blow moulding: extrusion, injection, and stretch blow moulding.
In extrusion blow moulding, a cylinder of plastic is melted and extruded into a hollow tube, called a parison. The parison is then placed in a mould and air is blown into it to expand and conform to the shape of the mould.
In injection blow moulding, a plastic preform is injected with a blow moulding machine and then reheated and blown into the desired shape. In stretch blow moulding, a preform is stretched and blown into the desired shape.
How do we work with blow moulding companies?
Although our in-mould methods cannot be applied during blow moulding, we can assist in the following ways:
- Blow moulding uses mainly thermoplastic and other raw materials (ABS, PS, PU etc.) to form products. Our paints are suitable for printing on these materials in order to give a permanent result
- Our post mould label-free graphics systems are definitely an option worth considering. Please contact us to discuss application methods and suitability for your projects
- Regardless of which raw material you use for injection moulding in your factory, whether they are thermoplastics or not, we can supply you with a suitable paint system and method to mark it
- We also design and supply functional coatings e.g. antistatic, anti-slip, flame-retardant
The different types of blow moulded products
Blow moulding is used to produce a wide range of plastic products, including bottles, containers, and automotive parts. Here is a bit more detail about the different types of blow moulding products:
- Plastic bottles: These are some of the most common products made using this process. They are used to package a wide range of products, including beverages, cleaning supplies, and personal care items.
- Containers: This process is also used to produce containers of various sizes and shapes, including tubs, pails, and drums. These are often used to store and transport liquids or dry goods.
- Automotive parts: It is also a common method for manufacturing parts for the automotive industry, including fuel tanks, bumper fascia, and grilles.
- Toys: Many children’s toys are made using this process, including plastic playhouses, toy cars, and dolls.
- Furniture: A variety of plastic furniture, including outdoor chairs, tables, and patio sets can be made using this process
- Recreational equipment: It is also used to manufacture recreational equipment, such as kayaks, canoes, and inflatable rafts.
- Medical equipment: This process is also used for medical equipment, including oxygen masks, nasal cannulas, and nebulizers.
- Appliances: Some small appliances, such as blenders and juicers, are made using this process
- Electronic components: Electronic devices such as cable connectors and cordless phone bases are also made via this process
- Industrial components: It is also used to produce a wide range of industrial components, including pipes, tubes, and fittings.
