A cooling block is a part of the working tools. Its purpose is to minimise the consumption of rubber when injecting products. This work aims to present the development of the locking needle's drive in the cooling block. The drive enables a user to specify a location which causes a cut. When material travels through the cut, it warms up due to friction. However, the increased temperature causes a decrease in time of vulcanisation and product injection cycles. The results showed the importance of location restrictions and higher temperature of the working environment.
