How Are Plastic Flip Top Caps for Bottles Made?
Ever twist open a lotion bottle or shampoo tube and wonder—how did this cap come to life? Let’s break down how plastic pokrovčki s preklopnim pokrovčkom move from raw idea to real, clickable parts.
From Resin Pellets to Flip Top Magic
To kick things off, plastic cap suppliers typically use polypropylene or polyethylene pellets—these materials strike a sweet balance between flexibility and durability. Melted under heavy heat, they get shaped using an injection molding machine. This process? Kind of wild.
Basically, molten plastic blasts into steel molds at high speed and pressure. Think hot goo meets cold metal. The mold defines everything: hinge, spout, walls, even those little snap-click parts that make a bottle flip cap satisfying to open.
Once it cools, the hardened cap pops out like candy from a mold tray. Voilà—cap’s born. Add trimming and finishing touches later, depending on whether it’s a 24 410 flip top cap, a 20/410 flip top cap, or a 28 400 flip top cap—sizes folks order in bulk.
