Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your reliable partner for premium thick-wall injection molding services specifically engineered for the cosmetic packaging industry. Since 2017, we have specialized in producing molds that protect your investment through advanced mold protection technology and precision design using UG (NX) and Parasolid software. Our thick-wall molding capability ensures your cosmetic jars, bottles, and caps achieve the luxurious feel and structural integrity demanded by high-end brands.
Our molds are built to withstand the rigors of thick-wall injection, delivering consistent wall thickness of 3mm to 15mm with minimal sink marks or warpage. By integrating wear-resistant inserts and robust cooling systems, we extend mold life significantly – reducing your long-term production costs. Every design is validated through advanced simulation to guarantee first-shot success.

Why Choose Our Thick-Wall Molding Service?
- Mold Protection Innovation: Our proprietary insert design and optimized cooling minimise thermal stress, preventing early mold failure even under high-pressure thick-wall cycles.
- Precision Engineering: Using UG (NX) and Parasolid, we deliver tolerances within ±0.02mm for critical dimensions, ensuring perfect fit between cap and bottle.
- Shorter Time-to-Market: Our in-house mold trial and adjustment process reduces sampling iterations – typical lead time is 25–40 working days for a new mold.
- Scalable Production: With a factory of 1,000–3,000 sqm and 51–100 skilled workers, we can handle volumes from prototype to mass production (50–500 sets/month).

Frequently Asked Questions
-
Q: What is the minimum wall thickness you can mold for cosmetic jars?
A: We specialize in thick-wall molding from 3mm up to 15mm. For very thin walls (below 3mm), we recommend our standard injection service, but our thick-wall service is optimized for premium, heavy-walled packaging. -
Q: Do you accept designs in other 3D formats besides UG and Parasolid?
A: Yes, we also work with STEP, IGES, and STL files. However, native UG (NX) or Parasolid files allow us to preserve mold protection features more accurately. -
Q: How does your mold protection technology extend tool life?
A: We use hardened steel inserts in high-wear areas, plus conformal cooling channels that reduce thermal stress. This prevents cracking and erosion, typically extending mold life by 30–50% compared to standard designs. -
Q: What is your typical lead time for a new cosmetic packaging mold?
A: For a standard thick-wall mold (cavity count 1×2 to 1×4), lead time is 25–40 working days including sample delivery. Rush orders may be possible upon request. -
Q: Can you add custom textures or logos on the mold surface?
A: Absolutely. We offer SPI finish grades, chemical etching, and laser engraving for logos or patterns. Discuss with our engineers during the design phase. -
Q: Do you provide samples before mass production?
A: Yes, we always provide T0 samples for your approval. We can iterate up to 3 rounds of adjustments at no extra cost (within reasonable scope). -
Q: What materials are compatible with your thick-wall molding service?
A: We work with ABS, PP, PETG, Acrylic (PMMA), PC, SAN, and other common cosmetic-grade resins. For specialty materials like biodegradable plastics, please consult our team. -
Q: Is there a minimum order quantity (MOQ) for mold production?
A: MOQ is 1 set (single-cavity or multi-cavity depending on complexity). For production parts, we typically recommend 5,000–10,000 pieces to optimize unit cost, but lower volumes are also possible.
*All specifications are subject to final design review and may vary based on material and complexity. Our sales team will provide a detailed proposal tailored to your project.
