Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd., a dedicated manufacturer established in 2017 with a factory spanning 1,000–3,000 square meters and a skilled team of 51–100 employees. We specialize in producing high-quality precision OEM injection molds for thick-wall cosmetic packaging. This particular mold is engineered with 1*4 cavities, a hot runner system, S136 steel, and a high-gloss finish, delivering outstanding efficiency and surface aesthetics for your premium cosmetic products.
Our mold is designed to meet the rigorous demands of the cosmetics industry, where both functional durability and visual appeal are critical. By leveraging advanced manufacturing capabilities and strict quality control, we ensure that each mold delivers consistent performance, reduced cycle times, and minimal waste. Below we outline the key features, technical specifications, and advantages that make this mold an ideal choice for your production line.
Key Features & Benefits
- Precision OEM Customization – Every mold is tailor-made according to your specific bottle, jar, or container design. We work closely with you to ensure perfect dimensions, parting lines, and wall thickness.
- Thick-Wall Capability – Ideal for heavy-duty cosmetic packaging that requires robust construction, such as cream jars, foundation bottles, or lotion containers. The thick-wall design prevents distortion and enhances product shelf life.
- 1*4 Cavity Balance – Four cavities in a single mold allow for efficient mass production while maintaining consistent quality across each part. The balanced fill ensures uniform shrinkage and dimensional accuracy.
- Hot Runner System – Eliminates sprue waste, reduces cycle time, and improves material flow. This system also enables precise temperature control, resulting in fewer defects like sink marks or short shots.
- S136 Mold Steel – A premium stainless steel known for its excellent corrosion resistance, high polishability, and toughness. It extends mold lifespan and ensures a mirror-like surface finish.
- High-Gloss Finish – Achieves a surface roughness below Ra 0.4 μm, providing a brilliant, transparent-like appearance for clear or translucent cosmetic packaging. This finish also improves mold release and reduces sticking.

Moreover, the robust S136 steel construction minimizes downtime for mold repairs, ensuring your production runs smoothly.
Our mold is also engineered with efficient cooling channels to maintain uniform temperature distribution, preventing warpage and internal stresses in thick-wall parts. This results in higher yield rates and consistent product quality, batch after batch. Whether you are producing a new line of luxury skincare jars or refillable foundation compacts, this mold delivers the precision and reliability you require.
