Compound Liner / Compound Lining Machine Cap Stopper Blade

Compound Liner / Compound Lining Machine Cap Stopper Blade
The cap stopper blade is an essential limiting and positioning component fitted on compound lining machines (can end glue injectors). During high-speed can sealing compound coating, this D2 steel stopper physically blocks and restricts the moving track of tin can ends, aerosol domes and paint bucket lids, ensuring every metal cap stays in a fixed, centered position when passing the glue injector head. Uniform cap positioning directly eliminates uneven sealing compound coating, offset glue lines and defective leak-prone cans.
Our cap stopper blades are fully CNC machined from solid D2 steel, then processed through professional heat treatment to reach hardness HRC 58–60. Compared with ordinary carbon steel stoppers, this high-hardness tool steel structure delivers outstanding anti-wear and anti-deformation performance, perfectly adapting to long-hour continuous operation in packaging workshops.
