Remark:
- 1. Thevulcanizingtime is calculated from the moment that the entire group (heating plates and molding frames) have reached the correct temperature.
2.General vulcanizing time is 60 minutes minimum at temperature 150- 165 ºC for 2x15mm thick mold. If thickness is more than 2x15mm. Basically 2minutes/1mm))
3.The pressure of the vulcanizer: about 120- 150bar.
- 4. Centrifugalcastingtime: 40 seconds, speed 800 rpm max
