Company portrait

In the mid-late 80s it was developed in the European Market a vent model that presented a groundbreaking technique characteristic, called self-cleaning. Translating this to the product, it meant the changing of the internal region of the vents slots adding them only a 5 ° angle. This technical aspect provided significant gain for foundries that until then had never achieved results such less downtime for machine cleaning and great improvement in the sand cores surface finish through their vents.

Aligned to this new technological reality, Valdir Zanatta and Jeanlis Brito Zanatta were willing to go throw their main challenge as entrepreneurs: develope self-cleaning vents that could overcome the imported vents performance. So Ventistamp Metallurgical was founded in 1995 as an answer to this scenario.

By using the casting process for manufacturing the vents, Ventistamp became a pioneer in the development of an exclusive internal competence, which was able to revolutionize the concept of venting tools, because it joined maximum sand clogging resistance, greater durability and competitive prices in one product.

Because of this technological evolution vents began to called Super Self-Cleaning by presenting not only a 5° angle as the European models, but a 35° taper now.

Currently Ventistamp Metallurgical is the biggest manufacturer of high technology ventilation systems in South America and also intends to gain such leadership in North America, offering solutions to foundries that produce sand cores and molds and also to those that produce aluminum pieces using permanent mold through gravity or pressure pouring.
