Innovative plastics specialist Tecni-Form Ltd. (Stone, UK) re-imagined the scope of rotational molding to produce an iPad-enabled foot-measurement device. The product has been rolled out to Clarks’ UK shoe stores.
The award-winning Clarks’ iPad foot gauge was designed and developed for the precise measurement of children’s feet by Designworks Windsor Ltd. The company initially challenged Tecni-Form to produce the device’s main body in white, medium-density polyethylene, specifying an exceptional surface finish to complement the appearance and feel of the iPad case.
Although rotational molding, using relatively low-cost tooling, makes good sense for large products (such as trash bins and kayaks) produced in sub-five-figure quantities, the technique is not conventionally prescribed to achieve a flawless, gloss finish and dimensional accuracy. The Tecni-Form team however, was eager to demonstrate its advances in the process, such that surface finish limitations are now a thing of the past. Additionally, the cost of rotational molding tools for the main body of the device was between one tenth and one twentieth of that estimated for a pair of imported injection molds for the same product.
