Introduction
As a professional manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in producing high-precision injection molds for the cosmetic packaging industry. Our OEM Thick-Wall PMMA Cosmetic Jar Injection Mold is designed with a 1*4 cavities hot runner system and constructed from premium S136 steel, offering exceptional durability and consistent performance for up to 300,000 shots. This mold is ideal for producing thick-wall cosmetic jars with crystal-clear transparency and excellent surface finish, meeting the rigorous demands of the beauty and personal care market.
Product Features & Technical Specifications
- Robust Construction: The mold is built from S136 stainless steel, known for its high corrosion resistance, hardness, and excellent polishability. This ensures long-term dimensional stability and a mirror-like cavity surface for flawless PMMA parts.
- Efficient Hot Runner System: The 1*4 hot runner design reduces material waste, shortens cycle times, and ensures uniform melt flow into each cavity, resulting in consistent part quality and faster production.
- Optimized for Thick-Wall Design: Specially engineered to handle the cooling and shrinkage challenges of thick-wall PMMA parts, the mold features advanced cooling channels that minimize warpage and sink marks.
- High Cavity Precision: Each of the four cavities is machined with tight tolerances, ensuring that every cosmetic jar maintains identical dimensions and weight.
- Extended Mold Life: Rated for 300,000 shots under normal operating conditions, this mold can sustain high-volume production with minimal maintenance, offering a cost-effective solution for mass production.
- OEM Customization: We can adjust mold design based on your specific jar dimensions, thread details, and surface finish requirements (e.g., matte, glossy, or textured).
Key Benefits for Your Business
- Reduce Production Costs: The hot runner system eliminates the need for cold runner regrinding, saving material and labor costs.
- Faster Time to Market: With a proven design and efficient production process, we can deliver your custom mold within a competitive lead time.
- Flawless Aesthetics: The S136 steel cavity, combined with optimized injection parameters, produces PMMA jars with high transparency, no bubbles, and scratch-resistant surfaces – perfect for premium cosmetic brands.
- Reliable Supply: As a factory with 1,000-3,000 sqm facility and 51-100 skilled workers, we can scale production to meet your volume demands.
