At Adtech, we look to deliver the best solutions to suit each clients’ specific needs. When it comes to the manufacturing of plastic products, we recommend vacuum forming as a go-to manufacturing process for the majority of plastic production.
What Does Vacuum Forming Involve?
Vacuum forming is a type of thermoforming process by which fluoroplastics are moulded into specific shapes. Vacuum-formed products are used in our daily lives, and often in places we don’t even realise, from yogurt pots to bath tubs, fridge liners to sandwich boxes, the process can be used to make fluoropolymers into all kinds of complex shapes and designs.
With vacuum forming, in order to produce a certain shape, plastic is heated until soft, draped over an already-formed mould, and then ejected and left to become solid –whereupon the new form is maintained.
As the pressures which are applied to the plastic during production are very low, vacuum-formed products can be made from several fluoroplastic materials including FEP, Tedlar PVF and PVDF. Also, because the fabrication process itself is very quick, this makes vacuum-forming ideal for repeat and high quantity orders, while the moulds themselves also have extended lifetimes when compared to other moulding processes.
Vacuum Forming for Low Cost Manufacturing
Since vacuum forming is a particularly simple form of thermoforming, the cost of the manufacturing process is significantly lower than with injection moulding methods. The production process is straightforward, the machinery is less costly, and the fluoroplastic materials themselves are also available at low cost. This means that operational expenses can be kept low, while the products themselves can be produced at an extremely high structural standard, making it a process popular with many.
