Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our latest OEM Laundry Detergent Bottle Blow Mold featuring a 2+2 cavities design and premium S136H steel inserts. Since our establishment in 2017, we have dedicated ourselves to delivering high-precision molds that boost production efficiency while maintaining exceptional product quality. This mold is engineered to produce durable, flawlessly shaped laundry detergent bottles with consistent wall thickness, meeting the demanding standards of the global packaging industry. With our TS16969 certified production processes, every mold we ship is built to last and perform reliably in continuous manufacturing environments.
Key Features & Technical Specifications
- 2+2 Cavities Layout: This optimized cavity arrangement allows you to run two independent molds simultaneously within one machine cycle, effectively doubling your output per hour compared to a standard 2-cavity mold. The balanced flow design ensures each cavity fills uniformly, reducing scrap rates.
- S136H Steel Inserts: S136H is a premium stainless steel known for its superior corrosion resistance, high hardness (after heat treatment achieving HRC 48-52), and excellent polishability. This extends mold life by resisting wear from abrasive plastic compounds and reduces maintenance downtime.
- Precision Machining: Our CNC machining centers and EDM equipment guarantee cavity tolerances within ±0.02mm. This ensures that each bottle meets exact dimensional requirements, including neck finish and handle geometry.
- Cooling System Optimization: Advanced conformal cooling channels or conventional spiral cooling (customizable) provide uniform temperature distribution across all cavities, shortening cycle times by up to 15% while preventing warpage.
- Flexible Compatibility: Designed to fit most major blow molding machine brands (e.g., Kautex, Bekum, Sidel) with standard mounting patterns. Adaptors or custom platens are available.
Technical Parameters (Typical Configuration)
| Parameter | Value |
| Number of Cavities | 2+2 (4 cavities in two independent pairs) |
| Insert Material | S136H (corrosion-resistant stainless steel) |
| Mold Base Material | P20 / 718H / 2311 (optional) |
| Max Bottle Volume | 0.5L – 5L (customizable) |
| Cycle Time Estimate | 8–15 seconds per cycle (depending on material and thickness) |
| Surface Finish | SPI A-2 / mirror finish (Ra ≤ 0.05μm) |
| Warranty | 12 months from date of shipment |
Customer Benefits: By choosing this 2+2 cavity blow mold, you gain a significant competitive advantage: increased production capacity without requiring extra floor space or additional machines. The S136H inserts drastically reduce the need for frequent mold polishing, saving labor costs and keeping your production line running. Our molds are engineered to run with HDPE, PP, PETG, and other common detergent bottle resins, allowing you to diversify your product range quickly. All molds undergo a rigorous 48-hour test run before dispatch to ensure flawless operation.

Frequently Asked Questions (FAQ)
-
Q: What is the benefit of a 2+2 cavity layout compared to a standard 4-cavity mold?
A: The 2+2 design allows independent operation of two pairs of cavities, making it easier to run different bottle sizes or colors in the same machine cycle. It also simplifies maintenance—if one pair needs servicing, the other can still be used. This design offers greater flexibility for manufacturers with variable order demands. -
Q: Is S136H suitable for high-tonnage production runs?
A: Yes. S136H is a hardened stainless steel (typically HRC 48-52) with excellent toughness and corrosion resistance, making it ideal for long production runs of corrosive materials like laundry detergent (which may contain surfactants and additives). Properly maintained, this mold can produce millions of bottles. -
Q: What blow molding machines can this mold be used with?
A: Our molds are designed to be adaptable. We offer standard mounting patterns to fit popular machines (Kautex, Bekum, Sidel, etc.) or we can custom-make the clamping plate to match your equipment. Please provide machine specifications when ordering. -
Q: What is the typical delivery time?
A: Standard delivery is 30–45 days after design approval. For complex molds or rush orders, we can discuss expedited production (e.g., 20–25 days) subject to current workload. -
Q: Do you provide sample testing before shipment?
A: Absolutely. We run a full 48-hour test on our in-house blow molding machine to verify cavity balance, bottle weight, and finish. We can also send you 10–20 sample bottles for your evaluation prior to shipping the mold. -
Q: What maintenance is required for S136H inserts?
A: Due to the corrosion-resistant properties, routine cleaning with mild solvents is sufficient. The inserts rarely need re-machining under normal use. We recommend annual inspection and, if necessary, light polishing. We can also supply spare inserts for critical dimensions. -
Q: Does your company have any quality certifications?
A: Yes, we are TS16969 certified (automotive-grade quality management), which ensures strict process control, traceability, and continuous improvement. Our quality system is regularly audited. -
Q: Can you customize the mold for a special bottle shape like an offset neck or an ergonomic grip?
A: Yes, we have extensive experience with complex geometries. Our engineering team uses Moldflow analysis to simulate filling and cooling, ensuring even material distribution. We can incorporate undercuts, handles, and special neck finishes as per your design.
