DARSIM Tool & Die, founded in 1992 by Jorge Simoes, began to really surge ahead after its Ótima housewares brand was brought to life by Jorge and his son Dario in 2012, as the need for quality and affordable houseware products emerged in South Africa, and later in southern Africa.

Exceptional skills in thin-wall injection moulding

By the time of the Ótima introduction, founder Jorge Simoes had built up exceptional skills in thin-wall injection moulding, not least based on his toolmaking prowess, allowing the business to split responsibilities with Jorge running the tool room and Dario taking care of production. This arrangement has proved very successful for the business, with the high-quality moulds built on site enabling it to convincingly expand production.
