The R&D centre makes use of a special designed software for complex 3D simulation of the mold cavity filling. We optimize positioning of vents in the mould and, if needed, recommend slight adjustment of the mould design.
After the simulation, results are verified in practice. A special piece of segment is manufactured. Next step involves pressing-out of samples and subsequent analysis in cooperation with customer.
Last but not least, GACZ offers training in vent installation and maintenance to all existing and new customers.

The GACZ Spring Vent consists of three parts: case, pin and spring.
The case is seated in a mold.
A pin on which the spring is pressed is secured inside the case.
This spring ensures that the valve is in the open position by default. The valve is closed by contact of the pin with the rubber compound. Upon contact, the valve is opened and allows residual air to escape from the mold cavity. After removing the tire from the press, the pressure on the pin is released and the valve is opened by the spring force.
Our company produces Eurovent type vents according to the Continental patent.
Production dates back to 2000. Sales are only for Continental and their approved supplier.
Gottschol Alcuilux CZ is one of the world's leading suppliers of this product.
Sipes are made of stainless steel sheets; they are tailored to customer requirements, directly for each mould type and tread pattern, out of sheets of various types and thicknesses (from 0.2 mm to 3 mm).Sipe types:
Copper electrodes are manufactured in order to insert sipes into milled aluminium castings. Following customer requirements, electrodes are then bent to required shapes.
Production is executed based on drawings supplied by customers.
