Step into our lid injection molding workshop, where the PP lids for stainless steel insulated bottles are produced with precision and consistency. This video shows how each lid is formed, colored, cooled, and assembled to meet strict quality standards for OEM/ODM drinkware production.
What you’ll see in this process:
Installation and calibration of the injection mold
Feeding PP resin pellets and custom color powder into the mixer
Material blending to achieve the exact Pantone color
High-temperature injection of molten PP into the mold
Cooling, pressure holding, and automated mold opening
Robotic arm extraction and orderly placement on the conveyor
Continuous injection cycles synced with machine parameters
Manual assembly of silicone gaskets for leak-proof sealing
QC checks for deformation, color accuracy, and fit tolerance
PP (polypropylene) is widely used for drinkware lids due to its safety, heat resistance, corrosion resistance, and ability to maintain a reliable airtight seal — making it ideal for large-scale production and customization.
If you’re sourcing insulated bottles or need custom lid designs, colors, or private molds, feel free to contact us anytime.
