Changzhou Hongxinyutai Precision Mold Co., Ltd. – established in 2017 with a 1,000–3,000 m² factory and a skilled team of 51–100 professionals – proudly presents our OEM Thick-Wall Cosmetic Compact Injection Service, validated under IATF 16949 quality management standards. This service delivers thick-walled compacts with a premium, scratch‑free surface finish that meets the stringent demands of luxury cosmetic brands. By leveraging advanced injection molding technology and precision tooling, we ensure each compact offers exceptional durability, flawless aesthetics, and consistent performance. Our commitment to zero defects and on‑time delivery makes us a reliable partner for North American, European, Asian, and global markets.
Key Features & Technical Specifications
- Thick-Wall Molding Expertise – Capable of molding parts with wall thicknesses exceeding 3 mm while minimizing sink marks and internal stresses. This is ideal for compacts that require a substantial feel and improved impact resistance.
- Scratch-Free Production Process – Our proprietary mold design and process parameters eliminate surface defects during ejection and handling. The resulting compacts have a smooth, mar‑free finish that retains its luster after repeated use.
- IATF 16949 Certified Quality System – Originally developed for automotive, this rigorous standard ensures traceability, process control, and continuous improvement. Every compact undergoes dimensional checks, visual inspection, and functional testing.
- Secondary Operations Ready – We offer in‑house hot stamping, silk screening, and assembly services to add logos, decorative patterns, or mirrors. All secondary processes are contamination‑free and scratch‑protected.
| Parameter | Details |
|---|---|
| Mold Steel Grade | P20, H13, S136 (or as required) |
| Injection Machine Range | 80 – 650 tons |
| Typical Wall Thickness | 2.5 – 6.0 mm (customizable) |
| Surface Roughness (Ra) | ≤ 0.8 μm (textured up to user specification) |
| Scratch Resistance Test | Pass 5B adhesion & 200 g load pencil hardness |
| Material Options | ABS, PC, ABS+PC, PMMA, SAN – all with scratch‑resistant grades available |
Our thick-wall injection process uses advanced simulation software to optimize gate location, cooling channels, and packing pressure. This ensures uniform shrinkage and warp‑free panels even at elevated thicknesses. For cosmetic compacts, the scratch‑free attribute is achieved through a combination of high‑polish mold cavities, controlled ejection speed, and protective handling throughout the production cycle. We also provide a cleanroom‑like environment for final assembly and packaging to prevent contamination.

Frequently Asked Questions (FAQ)
-
Q: What materials do you recommend for a scratch‑free cosmetic compact?
A: We commonly use ABS, PC/ABS, or PMMA with scratch‑resistant additives. The final choice depends on your desired gloss, impact strength, and cost target. We can also evaluate bio‑based or recycled materials upon request. -
Q: Can you achieve a high‑gloss surface without any flow marks?
A: Yes. Our mold flow analysis and optimized gate design minimize weld lines and flow marks. For thick‑wall parts, we use sequential valve gating and controlled melt temperature to ensure a uniform surface finish. -
Q: What is the typical lead time for a new tool and first samples?
A: Lead time depends on tool complexity and size. For a medium‑sized compact mold (cavity count 2+2), we estimate 25–35 days for tool manufacturing and 5–7 days for sample injection and inspection. Faster turnaround may be arranged with a surcharge. -
Q: Do you provide design assistance for thick‑wall parts?
A: Absolutely. Our engineering team will review your 3D model and provide DFM feedback to avoid sink marks, improve fill balance, and reduce cycle time. We also suggest optimal wall thickness distribution and rib geometry. -
Q: How do you guarantee scratch‑free during mass production?
A: We implement strict handling protocols: robotic extraction, padded conveyor belts, and clean‑room packaging. In‑mold protective coatings and anti‑scratch mold inserts are also available as options. -
Q: What quality documents are included with each shipment?
A: Every shipment comes with a Certificate of Conformance (IATF 16949 based), dimensional report (CMM/fixture), material certificate, and visual inspection records. Additional reports (e.g., RoHS, REACH) can be provided upon request. -
Q: Can you integrate a mirror or a hinge into the compact during molding?
A: Yes. We can design and mold compacts with living hinges, snap‑fit closures, or insert‑molded mirrors (using pre‑cut glass or plastic). For hinges, we recommend using polypropylene or a flexible TPE for durability. -
Q: What is the minimum order quantity (MOQ) for an OEM project?
A: For a new tool, the MOQ is typically 10,000 units per year. However, we are flexible for pilot runs or limited editions. Contact us with your project volume to discuss options.
