In the early stages, these tanks were supplied by external companies. However, with market growth and the need to respond more quickly to demand, the company installed its first rotomolding machine in 1982 and began in-house production.

In 2004, with the opening of a manufacturing unit dedicated exclusively to rotomolding, Pulverizadores Rocha began handling a large portion of the production internally (around 60%), while maintaining the remainder through subcontracting.

Today, with extensive experience and accumulated know-how, the company positions itself as a key partner in the development of innovative projects in the field of rotomolding.
