There are many factors that affect the quality of the Composite Machine, but the basic factors are the conditions directly related to the compound process: compound base material, adhesive, compound steel roller / rubber roller and Composite Machine. The influence factors of the laminating machine uniformity are different in the transverse and longitudinal direction, so the control measures are also different correspondingly. In the specific implementation, it is not only related to the design and manufacture of the machine, but also related to the operation and process control.

　　1. Composite substrate: mainly material, surface characteristics, thickness and uniformity.

　　2. Adhesive: mainly its working viscosity, affinity and adhesion to the surface of the substrate.

　　3. Composite steel roller: it is not only the direct carrier of adhesive, but also the support benchmark of composite substrate and cot, so it is the core of the whole composite mechanism. The form and position tolerance, rigidity, dynamic and static balance mass, surface quality, temperature uniformity and thermal deformation condition all affect the uniformity of the composite.

　　4. Compound rubber cot: rubber cot is an important variable of compound quality. Its material (such as rubber layer life), hardness, form and position tolerance, rigidity, dynamic and static balance quality, surface quality and thermal deformation condition also affect the uniformity of compound.

　　5. Compounding machine: it is the basic platform for compounding. In addition to the accuracy and sensitivity of the compound steel roll and cot pressing mechanism, it also includes the design of the highest running speed, the overall stability of the machine, etc.
