At Changzhou Hongxinyutai Precision Mold Co., Ltd., we specialize in delivering high-precision blow molds tailored for the production of laundry detergent bottles. Our OEM Laundry Detergent Bottle Blow Mold features premium S136H stainless steel construction with a sandblasted matte finish, ensuring exceptional durability, corrosion resistance, and a flawless surface for your bottle production. With over 7 years of mold manufacturing experience since 2017, our factory spanning 1,000–3,000 square meters and a dedicated team of 51–100 professionals, we provide reliable solutions for global markets including North America, Europe, Southeast Asia, and more.
This blow mold is designed to produce consistent, high-quality laundry detergent bottles that meet rigorous industry standards. The S136H steel offers superior hardness and wear resistance, while the sandblasted matte finish reduces sticking and improves release efficiency. Every mold undergoes rigorous quality checks to achieve long service life and low maintenance. Below are the key technical specifications and features.
Key Features & Technical Specifications
- Material Excellence: Made from S136H stainless steel (equivalent to DIN 1.2083), heat-treated to HRC 48–52 for optimal hardness and toughness.
- Surface Treatment: Sandblasted matte finish reduces friction, prevents scratches on bottle surface, and minimizes residue buildup.
- Precision Machining: CNC machining with tolerances within ±0.02mm, ensuring consistent wall thickness and bottle weight.
- Versatile Compatibility: Suitable for extrusion blow molding (EBM) and injection blow molding (IBM) machines; customizable to fit major brands (e.g., Kautex, Bekum, Sidel).
- Long Mold Life: Designed for over 1 million cycles under normal operating conditions, reducing replacement costs.
- Easy Maintenance: Modular design allows quick cavity replacement; sandblasted surface resists corrosion from detergent chemicals.
- Custom Cavity Layout: Single-cavity to multi-cavity (up to 8) configurations available to optimize production efficiency.
- Advanced Cooling System: Optimized water channels for uniform cooling, reducing cycle time by 10–15%.

Frequently Asked Questions
-
Q: What is the typical lead time for a custom laundry detergent bottle blow mold?
A: Lead time depends on cavity count and complexity, but generally ranges from 30 to 45 days. We will provide an exact schedule after reviewing your design. -
Q: Can this mold be used for other types of bottles (e.g., shampoo, dish soap)?
A: Yes, the mold can be adapted for similar plastic bottles. However, the design must be tailored to the specific bottle geometry. Our team can assist with modifications. -
Q: What is the advantage of sandblasted matte finish over a polished finish?
A: Sandblasted matte reduces friction, helps prevent scratches on the bottle surface, minimizes residue buildup, and improves release behavior for detergents with higher viscosity. -
Q: Do you provide mold trial support?
A: Yes, we offer on-site or remote technical support during the trial run. We can also conduct a trial at our facility upon request. -
Q: What materials are recommended for the bottle? Is the mold compatible with HDPE, PET, or PP?
A: Our mold is optimized for HDPE and PP, commonly used for laundry detergent bottles. For PET, we recommend a injection blow mold design. Please specify your material when ordering. -
Q: How do you ensure the mold cavity meets my bottle design specifications?
A: We use advanced CAD/CAM software and coordinate measuring machines (CMM) to verify all critical dimensions. A final inspection report is provided with each shipment. -
Q: What is the warranty policy?
A: We offer a 12-month warranty covering manufacturing defects. Normal wear of wear parts (e.g., neck rings) is not covered. Detailed terms are provided in the sales contract. -
Q: Can I request a sample before mass production?
A: Absolutely. We can produce a sample mold for trial or provide a few sample bottles from a prototype cavity. Additional costs apply for sample tooling.
