Which country is the nozzle of domestic thermal foaming photo machine produced? Or can China produce thermal foaming nozzles?

Suzhou Ruifa fired a lot some time ago, but now it's gone. China's R&D institutions are like this, and they have no stamina. A few years ago, a boss invested about10 million in R&D. At first, he was called fierce, but later he dropped it. It seems that this nozzle has always been a pain for China people. The country only cares about heavy industry, not light industry. Why is the overcapacity of steel in recent years the result of state support, and this piece has always been processed in the light industry?
