Abstract
A device for polymerizing lactams in molds, comprising: a reservoir for storing lactam, wherein said reservoir is kept at a temperature which varies in the range of 135-150° C. for melting the lactam and keeping it in melted state; lactam feeding means comprising dosing pipes for feeding the lactam from the reservoir, first dosing means for feeding an initiator; second dosing means for feeding an activator; a mixing head configured to receive the lactam, the initiator and the activator from respectively said lactam feeding means, said first dosing means and said second dosing means. The initiator and activator are liquid, and the cited reservoir and lactam feeding means are located within a heater configured to maintain the temperature of the lactam at a substantially constant value until it reaches the mixing head.
