    Dome blowing process

    Our commitment to innovation and technology plays a large part in our ability to deliver on that ethos, and is reflected in the high-tech equipment we utilise in our 20,000 sq. ft. manufacturing facility.

    The dome blowing process consists of heating a piece of acrylic until it reaches a temperature at which it starts to soften. Once this has happened the piece of acrylic is loaded into the Dome Blowing unit, where it is clamped into place under a circular ring.

    Air pressure is then applied to the underside of the acrylic, and it is blown up and out in a uniform dome shape until it reaches the desired height. Once it has cooled down, it can be removed from the circular clamp and is immediately ready to be used.

    Experienced engineers

    Our ability to work on projects as varied as free standing display units and leaflet holders is based on our expert application of a wide range of plastic forming techniques, and dome blowing is one of the most effective ways of working with acrylic to deliver high quality, precision results.

    Our commitment to utilising the latest techniques and cutting edge equipment only delivers the very best results because of the excellence of the ASH Plastics team.

    Our engineers and technicians have over 100 years’ worth of combined experience to draw upon and every member of the team works to deliver on the ethos of excellence, quality and value.

    Frequently Asked Questions

    Dome blowing is a particular process that uses heat to expand materials and create a dome-shaped finish. The particular height and size of the dome depend on the requirements of the client in question.

    Before being loaded into a dome-blowing machine, heat is delivered to a piece of material until it reaches a certain temperature. At this point, the material softens and then is loaded into the blowing machine where it’s clamped into place.

    At this point, air pressure is applied to the underside of the material, blown up and out. This creates a uniform dome shape that can expand to the desired height and size. Once cooled, it can be unclamped and used immediately.

    There are a variety of dome-blowing products that can be made. For example, medical supplies and parts can benefit from hollow containers used for medication, as well as spray bottles, storage containers, and more.

    Packaging companies can utilize dome blow molding to create caps for various containers used in a variety of industries.

    A variety of materials can be used to create such a shape. Such materials that are suitable for dome blowing include; Acrylic, Polycarbonate, Glass, PVC, ABS, and High Impact Polystyrene.

    Acrylic and polycarbonate are often considered two of the best materials used for dome blowing due to their durability and strength. Glass can often be the most vulnerable but can often look the most luxurious.
