VentThermoforming is a manufacturing process in which a plastic sheet is heated to a temperature where it becomes pliable and can be formed to the required shape in a mould.

Thin-gauge thermoforming is used to manufacture items such as disposable cups and containers and thick-gauge thermoforming is used to manufacture a diverse range of products from vehicle parts, transit trays, plastic pallets and some building materials to name a few.

Thermoforming requires hundreds of individual radiant heaters that must be accurately controlled and quickly reset to make different shapes. The accuracy of a thermoforming machine is critical, any slight deviation by only a few degrees can significantly affect product quality.

The building and construction trade in Europe ploughs through nearly 10 million tonnes of plastics yearly. This figure represents over 20% of the total European plastic consumption, second only to plastic used for packaging. Over 50% of the building plastics used are for new pipe installations.

Plastic thermoforming with HIPs (High Impact Polystyrene) is widely used in the building trade from roof vents to underfloor heating systems, ducting, fascia panels and bath and shower rooms. Building product manufacturers have realised that thermoforming is an exceptionally efficient process in comparison to injection moulding and other plastic manufacturing processes which have much higher running and tool costs. Thermoforming has close similarity to vacuum forming. In thermoforming air pressure is utilised more significantly as well as plug assisted forming of the softened plastic sheet. The process is invariably automated and produces faster cycle times than the vacuum forming process. Plastic is often the hidden material in construction, be it pipes or insulation.

The use of thermoformed plastics have risen significantly in the construction industry because of its favourable properties:

•  Light but Strong: Thermoformed plastics are strong yet still lightweight, making them easy to transport and manoeuvre.

•  Low Maintenance: Plastic requires little to no maintenance and is easy to install.

•  Cost Effective: Plastics usually cost much less than traditional building materials.

•  Dependability: Unlike many traditional building materials, plastic does not rot or corrode.

•  Durability: Plastic is durable, being knock and scratch resistant and can withstand adverse weather conditions.

•  Convenient: Thermoformed plastics can form components that can be easily jointed, with snap-fit connections and product tight seals.

•  Design Capabilities: There are limitless design possibilities with thermoformed plastics.

•  Ease of Use: Plastic can be easily sawn and nailed on site using standard building and construction tools.

•  Built to last: Plastics have a long-life span, an important feature in the construction industry.

•  Safe: Plastic does not conduct electricity.

•  Environmentally friendly: Plastic can be recycled.

•  Hygienic: Plastic pipes is the material of choice for water transportation, a hygienic option for household surfaces due to plastic’s ease of cleaning and impermeability.
