Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for high-performance injection molds. Since 2017, we have specialized in manufacturing precision molds for the cosmetic industry. Our OEM Cosmetic Compact Injection Mold: 1*4 Cavities, Scratch-Free Production is engineered to deliver flawless finishing and exceptional durability. With a factory size of 1,000-3,000 square meters and a skilled team of 51-100 employees, we ensure every mold meets rigorous quality standards.
This mold is designed for producing cosmetic compacts (powder cases, eye shadows, blushes) with a 1x4 cavity configuration, which balances efficiency and precision. The scratch-free surface finish is achieved through advanced polishing techniques and strict process control, minimizing defects and secondary operations. Whether you need a full custom design or a standard solution, our mold offers reliability and consistent output.
Key Features & Technical Specifications
- Cavity Configuration: 1x4 cavities – optimized for medium-volume production, allowing 4 parts per cycle while maintaining uniform cooling and filling.
- Scratch-Free Technology: Mirror-polished cavity surfaces (Ra ≤ 0.02 μm) combined with gentle ejection mechanisms to prevent any marks on the finished product.
- Material Choice: Made from premium tool steels such as NAK80, S136, or 8407, ensuring high wear resistance and corrosion resistance for long mold life.
- Injection System: Supports both hot runner (with individual nozzle control) and cold runner designs, depending on your production requirements.
- Mold Base: Standard or custom mold base (LKM, HASCO, DME) available; all components are hardened and precision-ground.
- Cooling System: Conformal cooling channels (optional) reduce cycle time by up to 30% and improve part quality.
- Mold Life Expectancy: Typically 500,000 – 1,000,000 shots with proper maintenance, reducing your tooling cost per part.
- Overall Dimensions: Customizable; typical compact mold sizes range from 400x400 mm to 600x600 mm depending on part geometry.

Frequently Asked Questions (FAQ)
-
Q: Can you produce molds for different compact shapes (round, square, oval)?
A: Yes, we can customize the mold cavity shape according to your design. The 1x4 cavity layout can accommodate various geometries as long as they fit within the mold footprint. -
Q: What injection molding machine size is needed for this mold?
A: Typically a 150-250 ton injection molding machine is suitable, but the exact requirement depends on the compact dimensions and material. We provide a mold layout drawing for compatibility check. -
Q: How do you achieve a scratch-free surface?
A: We use a combination of high-polish steel (Ra ≤ 0.02 μm) and a specially designed ejection system with minimal contact points. Additionally, we apply a protective coating on the cavity surface if requested (e.g., DLC coating). -
Q: What materials can be used for the compact (e.g., ABS, PP, PET)?
A: The mold is compatible with a wide range of thermoplastics including PP, ABS, SAN, PET, and PMMA. We can adjust the cooling and gate design accordingly for the material you specify. -
Q: Do you offer mold trial and sample parts before shipment?
A: Yes, we provide full mold trial service at our facility. You will receive sample parts for approval before we proceed with final shipment. Video or on-site inspections are also available. -
Q: Can I modify the cavity count (e.g., 1x2 or 1x6)?
A: Absolutely. The 1x4 is our standard, but we can design molds with 1x2, 1x6, or even 2x4 cavities based on your volume requirements. The mold base and cooling system will be optimized accordingly. -
Q: What is the warranty on your molds?
A: We offer a 12-month warranty against manufacturing defects from the date of shipment. During this period, we cover repairs or replacements for any faults arising from material or workmanship issues. -
Q: How do you ensure the mold complies with international quality standards?
A: Our production follows TS16969 guidelines, and we perform dimensional inspection (CMM) and surface finish checks on every cavity. We also provide a quality report with each mold delivery.
