Under normal circumstances, the extruder is a key piece of equipment in the entire production process and is mainly used for heating and mixing PVB resin, plasticizers and other reagents.

Even thickness of PVB is very important to the success of lamination. Failure in thickness control will lead to bubbling between glasses during pressurization.

Based on years of industry experience, the company's R & D temperature and humidity control technology can accurately adjust the moisture content of the film according to the different specifications of the film or the requirements of different customers. It has been verified to have good results through a large number of practical applications.

In order to minimize the influence of impurity to customers, we possess an advanced infrared impurity control system. The system includes a sensitive camera which can detect particles with size as small as 0.3mm.

We possess an unique winding up system. As there is an accumulation of energy in PVB film during heating process and abrasion, we must release the energy and cool down before winding up the film to minimize the film shrinkage. The system can help minimize bad glass production led by PVB shrinkage.
