As a specialized manufacturer of precision blow molds, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly offers this OEM Blow Molding for HDPE Detergent Bottles featuring a 2+2 cavities configuration and robotic pick & place automation. With over 7 years of experience (since 2017), a factory spanning 1,000–3,000 sqm, and a dedicated team of 51–100 skilled professionals, we deliver molds that maximize production efficiency and product consistency. Our TS16969-certified manufacturing process ensures every mold meets stringent quality standards, making us a trusted partner for global clients across North America, Europe, Asia, and beyond.
This blow mold is engineered for high-volume production of HDPE detergent bottles, offering an optimal balance of speed, precision, and durability. The 2+2 cavity design (two cavities for the bottle body and two for integrated handles or caps) allows you to produce multiple components simultaneously, significantly increasing output per cycle. Combined with robotic pick & place technology, the mold reduces manual intervention, minimizes cycle times, and ensures consistent part removal without deformation. Below, we detail the key features and technical specifications that set this mold apart.
Key Features & Benefits
- 2+2 Cavity Layout: Doubles production efficiency by molding two bottle bodies and two additional components (e.g., handles or closures) in one cycle. Ideal for detergent bottles requiring separate caps or ergonomic grips.
- Robotic Pick & Place System: Fully automated part removal reduces labor costs, prevents contamination, and eliminates manual handling defects. Compatible with most standard blow molding machines.
- HDPE-Optimized Design: Precision cooling channels and optimized flow paths ensure uniform wall thickness, reducing material waste and improving bottle strength. Suitable for lightweight yet durable detergent containers.
- High Wear Resistance: Constructed from premium tool steel (e.g., P20, 718H, or H13) with hardened surfaces, extending mold life to hundreds of thousands of cycles even under continuous production.
- Quick Mold Change: Modular design with standardized interfaces enables fast changeovers between different bottle sizes, minimizing downtime for customers with diverse product lines.
- Customization Options: OEM service includes tailored cavity configurations, custom engravings (logo, barcode, recycling symbols), and integration with existing blow molding lines.

Frequently Asked Questions (FAQ)
Q1: Can this mold produce bottles with different neck finishes?
A: Yes, the mold can be customized to produce various neck finishes (e.g., 28mm, 38mm, or snap-on caps). The 2+2 cavity arrangement allows one cavity to be dedicated to a special neck design if needed.
Q2: What is the typical delivery time for a custom mold?
A: Standard delivery is 30–45 days after design approval, depending on complexity. Urgent orders can be expedited upon request.
Q3: Do you provide trial runs before shipment?
A: Yes, we offer trial runs at our factory to ensure the mold produces bottles meeting your specifications. Videos and samples are provided for your approval.
Q4: What is the minimum order quantity (MOQ)?
A: For this 2+2 cavity mold, the MOQ is 1 set. We also accept small orders for prototypes and testing.
Q5: Can the robotic pick & place system be retrofitted to existing machines?
A: The mold is designed to be compatible with standard robot interfaces. Our engineering team can assist in integrating the system with your blow molding line.
Q6: What warranty do you offer?
A: We provide a 12-month warranty against defects in materials and workmanship, covering all components including cooling channels and robotic fixtures.
Q7: Is the mold suitable for food-grade HDPE?
A: Yes, the mold can be manufactured with food-grade compatible steel and surface treatment. However, for food-contact applications, we recommend additional certification validation by the customer’s local authority.
