Processing

What is Injection moulding?

Injection moulding is one of the most common manufacturing processes to produce plastic products in large volumes.

The process: the thermoplastic raw materials (often plastic compounds) are fed via a hopper into a heated barrel. The material will then be melted via an outside heater band and injected in the mould cavity using a single-screw. The mould will then be cooled to solidify the material in the preferred shape of the plastic end-product.

This manufacturing process is used in a wide range of industries such as automotive, packaging, household products and many more.

What is Blow moulding?

Blow moulding is a manufacturing process that is used to produce hollow objects made of plastic in large volumes.

There are two blow moulding processes:

Injection blow moulding: first a semi-finished product will be injection moulded into a plastic parison. Afterwards, the parison is placed into a heated mould and compressed air is used to blow the plastic parison across the interior walls of the mould cavity.
Extrusion blow moulding: the process is similar except from the first step. First, plastic compounds will be melted and extruded into the mould. When the mould closes compressed air will used to blow the plastic across the interior walls of the mould cavity.

This manufacturing process is used in a wide range of industries such as packaging (bottles) and many more.

What is Extrusion?

Extrusion is a manufacturing process that is used to produce continues profiles.

The process: the thermoplastic raw material (often plastic compounds) is gravity fed via a hopper into the barrel using a rotating screw. Each screw set up is different since it depends on the raw material that is processed. In the barrel the material will be heated and transported via the screw and will finally flow through a die. The die forms the shape of the plastic material. After exiting the die, a cool process is needed to solidify the plastic product.

Extrusions is also an overarching manufacturing processes such as cast film extrusion, thermoforming, extrusion coating and many more.

What is Co-extrusion?

Co-extrusion is a form of an extrusion process that is used to create two or more materials through a single die.

The process: two or more thermoplastic materials will be melted via an extrusion process; each material will be fed via an individual extruder through a single die. In this way, the materials will weld or merge into solidified single structure before it enters the cooling process. The main advantage of coextrusion is that each material maintains its properties.

The Compound Company offers multiple products as raw material for a co-extrusion process. Please go to our product selector to see which grades are interesting for you.

What is Cast film extrusion?

Cast-film extrusion is a form of an extrusion process that is used to create sheets or films.

The process: the thermoplastic raw materials will be extruded through a slot die onto a chill roll which is cooled and then the film/sheet passes through a series of rollers and eventually will be wound up.

The Compound Company offers multiple products as raw material for cast film processes. Please go to our product selector to see which grades are interesting for you.

What is Blown film extrusion?

Blown film extrusion is a form of an extrusion process that is used to create films.

The process: the thermoplastic raw materials will be extruded through a circle shaped die and then pressured air will be used to expand the film in the desired dimensions. Afterwards, it will be cooled down to solidify the product.

Blow film extrusion is used for applications such as disposable grocery bags.

What is Multi Bubble Proces?

Multi bubble proces is a form of an extrusion process that is used to produce films with unique structures that are not easily possible by standard film production processes.

The process is a two-step process: (1) the thermoplastic raw materials will be extruded as a tube in a bath with warm water. The warm bath causes that the plastic raw materials will quenches and reduces and control the crystallinity. (2) The extruded tube will be reheated with a warm bath or infrared to its orientation temperature. Then the tube is expanded by using pressured air. Similar as blown film extrusion but using lower temperatures.

What is Extrusion Coating?

Extrusion coating is a form of an extrusion process that is used to produce products with coatings.

The process: the thermoplastic raw materials will be extruded through a horizontal shaped slot-die. The extruded thermoplastic raw materials will be extruded onto a substrate. In this way the product is permanently coated.

The Compound Company offers multiple products as raw material for the extrusion coating process. Please go to our product selector to see which grades are interesting for you.

What is Extrusion Lamination?

Extrusion lamination is a form of an extrusion process that is used to produce products with two different substrates.

The process: the thermoplastic raw materials will be extruded through a horizontal shaped slot-die. The extruded thermoplastic raw materials will be extruded between two different substrates and could be seen as a bonding agent.

The Compound Company offers multiple products as raw material for the extrusion lamination process. Please go to our product selector to see which grades are interesting for you.

What is Thermoforming?

Thermoforming is a manufacturing process that is often used to produce different type of rigid/semi-rigid packaging articles.

The process: firstly, the sheet is being produced using a cast film extrusion process. Afterwards, the sheet will be heated and stretched over or into a mould to form the products and will be cooled down. Cutting machinery will cut the products into individual products.

The Compound Company offers additives and plastic compounds as raw material for the thermoforming process. Please go to our product selector to see which grades are interesting for you.

What is Compounding?

Compounding is manufacturing process that is used to produce plastics with specific/desired properties of the compound.

The process: raw thermoplastic materials and additives are melt-blend based on a formulation to achieve specific properties. The raw material and additives will be melt-blend in an extruder using single- or twin-screws. Additives will be feed via hoppers (side feeders). The material will be transported and blend with the additives due to the rotating screw(s). Afterwards, there will be a cool down step to solidify the polymers using a water bath or air cooling.

Are you looking for a tolling partner?
Compounding is the core competency of The Compound Company and therefore the ideal compounding partner if you are looking for extra production capacity.

What is Rotation moulding?

Rotation moulding is a manufacturing process that is used to produce great hollow plastics products.

The process: thermoplastic raw material, mainly in powder form, is placed into a hollow mould. The mould will then be closed and slowly rotated bi-axially and then the mould will be heated in the oven whilst rotating. Due to its rotating and heating the polymer, the polymer will melt onto the sides of the mould. Once the melted polymer has fully covered the shapes of the mould, the mould will be cooled down to solidify the polymer and get the desired shape of the product.

What is Compression moulding?

Injection moulding is a manufacturing processes to produce plastic products in large volumes.

The process: raw material (thermoset or thermoplastic) is placed into a mould cavity that is open and heated. The mould will then be closed by a top plug and compressed with hydraulic pressure to ensure that the raw material is solidified over the total mould shape.
