Sponge Rubber Extrusion Process
Rubber profiles are extruded from the die and cured in a series of microwave units to hold their finished form. The Ballotini curing process is a very different one. On a Ballotini line the natural rubber is fed from the extruder through the die plate and then passed through a Ballotini bath. Ballotini are small pure soda lime glass balls that are heated up to approximately 220 degrees, the heat control and heat transfer makes it a perfect partnership for use with sponge compounds due to the chemical composition. This curing process results in a sponge profile that can then be packaged to the customer’s requirements.
