✔ Key Features & Technical Specifications
- Premium Material – S136 Steel: High-grade stainless steel with excellent corrosion resistance, polishability, and wear resistance. Ideal for cosmetic molds requiring mirror-like cavity surfaces.
- Scratch-Free Surface Technology: Our proprietary polishing and texturing processes ensure the molded containers are free of scratches, blemishes, or flow marks, meeting luxury packaging standards.
- Thick-Wall Design Optimization: The mold is specifically designed for square containers with thick walls (typically 2–5 mm), ensuring even cooling, minimal warpage, and consistent wall thickness.
- IATF 16949 Certified Manufacturing: Our production follows the automotive-grade quality standard, guaranteeing strict process control, traceability, and continuous improvement – now applied to precision cosmetic molds.
- High Precision & Repeatability: Machined with CNC and EDM within tolerances of ±0.01 mm, ensuring each cavity produces identical parts shot after shot.
- Customizable Cooling System: Optimized conformal cooling channels reduce cycle time by up to 20% and improve part quality.
- Modular Mold Base (Optional): Available with standard or custom mold bases (LKM, HASCO, DME) for easy integration with injection molding machines from 100 to 500 tons.
📋 Technical Parameters (Typical)
| Parameter | Value |
|---|---|
| Steel Grade (Core & Cavity) | S136 (Hardness 48–52 HRC) |
| Surface Roughness (Cavity) | Ra ≤ 0.025 μm (Mirror finish) |
| Mold Life (Expected) | ≥1,000,000 cycles with regular maintenance |
| Standard Cavity Number | 1 to 8 cavities (customizable) |
| Injection Machine Tonnage | 100–500 tons |
| Cooling System | Conformal cooling (optional) |
| Application | Square thick-wall cosmetic jars, compacts, pots |
This mold is especially suitable for high-end cosmetic brands that demand scratch-free and glossy surfaces. The S136 steel not only provides excellent corrosion resistance against cosmetic formulations but also maintains its polish over long production runs, reducing downtime for re-polishing.

❓ Frequently Asked Questions
- Q: Why is S136 steel chosen for this mold? A: S136 (a type of 420 stainless steel) offers excellent corrosion resistance, high polishability to a mirror finish, and good wear resistance. It is the standard choice for cosmetic molds where surface quality and scratch resistance are critical.
- Q: How do you guarantee a scratch-free surface on the molded containers? A: We use advanced polishing techniques (diamond compound) to achieve Ra ≤ 0.025 μm cavity surface, combined with optimized ejection and cooling to avoid any marks. Surface quality is measured and reported.
- Q: What is the expected mold life? A: With proper maintenance (regular cleaning, lubrication, and occasional re-polishing), the mold typically exceeds 1,000,000 cycles. The S136 steel's hardness and wear resistance contribute to longevity.
- Q: Can the cavity number be customized? A: Yes, we design the mold according to your annual volume and machine capacity. Common configurations are 1, 2, 4, or 8 cavities. We can also design multi-level molds for higher output.
- Q: What is the typical lead time? A: Depending on complexity, lead times range from 30 to 45 working days. Rush orders can be accommodated with an expedite fee. We keep you updated on progress.
- Q: Does the mold comply with IATF 16949? A: Yes, our entire manufacturing process is certified under IATF 16949. This includes design control, supplier management, process control, and final inspection. We provide a certificate of compliance.
- Q: What injection molding machine tonnage is required? A: For typical square thick-wall containers (e.g., 50ml–200ml), a machine between 100 and 250 tons is suitable. We provide detailed mold dimensions and shot weight data for your machine selection.
- Q: Do you offer after-sales service and spare parts? A: Absolutely. We provide full technical support, spare parts (ejector pins, springs, hot runner nozzles if used), and can assist with mold troubleshooting. Our team responds within 24 hours.
