I.Color: Slight color deviation from the Pantone color chart will be determined based on the Pantone color chart. II.Finished Product Defects：Mold line misalignment is noticeable and can cause hand injuries. III. Common Appearance Defects: Cracks, chips, chipped corners, deformation, glass ripping, internal wall sticking, and sharp punctures that may affect the seal and pose a risk of injury. Cold marks, pitting, brush marks, wrinkles, stubble marks, scissor marks, base thickness variations, and minor scratches may also be present on the bottle. Discoloration, black spots, bubbles, and pinholes may be present elsewhere. IV.Foreign Objects: Broken glass, insects, metal, blood, and other issues. Check the bottle's interior and exterior for visible foreign objects such as oil, water, paper scraps, and small impurities. V. Process Spraying The sprayed surface is not smooth or flat; it may exhibit streaks, wrinkles, frosting, orange peel, or other defects. On the main viewing surface: Two p...

Test focus: Chemical Resistance: Products containing strong acids or bases, particularly those containing strong acids or bases, may corrode the glass surface. This corrosion may cause glass flakes to break off, form visible particles, or imperceptibly damage the integrity of the glass. Furthermore, these substances can dissolve alkali metal ions. If these ions accumulate on or within the glass, they can cause a dramatic shift in the glass's pH, altering its chemical properties and ultimately affecting its performance and lifespan. Inner layer surface treatment: whether the release agent, siliconizing agent or other inner coating is compatible with the contents, whether it migrates or affects the stability of the contents. Metal Cap/Pump Head Compatibility: While glass itself is inert, the accompanying metal cap (available in tinplate or aluminum) and pump head (made from various types of plastic and metal springs) must be compatible with the contents. This is because corrosion and rus...

1.Precision mold technology The unique shape of perfume bottles (such as curved bottles and special-shaped bottle mouths) relies on precision molds. Precision mold technology determines the shape, size and detail accuracy of the bottle.Through high-precision CNC machine tools and computer-aided design, the mold can achieve complex patterns and curves. The mold is made using CNC machining technology.The accuracy can be controlled within ±0.01mm, which can accurately restore the design details.Whether it is a square bottle with sharp edges or a round bottle with smooth curves, the dimensions can be guaranteed to be consistent between batches. 2.Automated production and testing The automated assembly line can achieve seamless connection between glass melting, blowing, forming, and cooling and setting, and its production efficiency is more than 3 times higher than traditional manual methods.The automated inspection system uses visual sensors and artificial intelligence to accurately...
