Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a dedicated manufacturer with over 7 years of experience in precision mold making. Our OEM Thick-Wall Cosmetic Bottle Mold featuring a 1*4 cavities hot runner system and designed for PMMA/PETG materials with a high-gloss mirror finish represents our commitment to quality and efficiency. This mold is engineered to produce thick-walled cosmetic bottles with exceptional surface clarity and dimensional accuracy, helping your brand stand out in competitive markets.
Our mold is built for high-volume production, reducing cycle times while maintaining superior part quality. The hot runner system ensures uniform melt flow, minimizes waste, and eliminates the need for secondary trimming. Combined with our precision machining and mirror-polished cavities, you get bottles that require no additional finishing – ready for filling and labeling right out of the mold.

Product Advantages
- High Efficiency: 1*4 cavity layout with hot runner system reduces cycle time by 20-30% compared to cold runner molds, increasing your output per hour.
- Superior Optical Clarity: The high-gloss mirror finish (SPI A1) ensures PMMA/PETG bottles achieve crystal-like transparency, enhancing product shelf appeal.
- Excellent Dimensional Stability: Thick-wall design combined with precision mold manufacturing maintains consistent wall thickness and prevents warpage, even for large bottles.
- Material Versatility: Optimized for PMMA and PETG – both materials require careful gate and temperature control, which our hot runner system provides.
- Reduced Defects: No weld lines, no flow marks, and minimal birefringence thanks to balanced hot runner manifold design.
- Easy Maintenance: Modular design allows quick cavity replacement; all cooling channels are accessible for cleaning.
- Customizable: We can modify cavity number, gate type, and cooling layout according to your bottle design specifications.
Our mold is particularly suitable for high-end cosmetic packaging where surface quality and precision are paramount. Whether you are producing skin care bottles, perfume bottles, or lotion containers, this mold delivers consistent results batch after batch.
