Injection Moulding.
Injection moulding of rubber is a production method where an uncured rubberstrip is fed into a mould by a heated feeding-screw. The temperature in the mould is between 170-200°C.
When all rubber is in injected, the curing-process (vulcanisation) is started. This takes between 90 and 300 seconds, depending on part-thickness and temperature.
Today HordaGruppen have 18 rubber presses where this method is used. From 130 tons of clamping force up to 520 tons.
Some of them are running without any personnel, which means a high degree of automatization and without any waste (flash).
