High Efficiency with 16 Cavities: Produces 16 caps per cycle, significantly boosting production output. Ideal for medium to high-volume cosmetic manufacturers.
Leak-Proof Performance: Precision-engineered core and cavity geometry ensure a tight seal between cap and bottle neck. The mold design includes advanced thread profiles and a sealing lip to prevent liquid leakage—critical for cosmetic products like shampoos, lotions, and essential oils.
Material Flexibility: Optimized for both PP and PE, giving you the freedom to choose the material that best suits your product’s compatibility and cost requirements. Both materials offer excellent chemical resistance and durability.
TS16969 Certification: Our molds are manufactured under a quality management system that meets the rigorous TS16969 standard—ensuring repeatable precision, consistent cycle times, and minimal downtime.
Customizable Options: We offer OEM services: you can customize cap design (height, diameter, thread type, color), mold steel grade, runner system (cold or hot runner), and surface finish (glossy, matte, textured). Our engineering team works closely with you to achieve your exact specifications.
Durable Mold Construction: Using premium steel (e.g., S136 for corrosion resistance, 2738 for toughness) and precision machining, our molds maintain tight tolerances over millions of cycles, reducing maintenance costs.
Fast Delivery: As a dedicated injection mold manufacturer, we leverage advanced CNC, EDM, and wire-cutting equipment to deliver within competitive lead times—typically 25-40 days depending on complexity.
Global Logistics: Shipped from ports in Jiangsu, Shanghai, or Shenzhen, we serve clients worldwide with safe, professional packaging.

Frequently Asked Questions (FAQ)

Q: What is the minimum order quantity (MOQ) for this mold?
A: As a standard injection mold, we offer MOQ of 1 set. However, for customization, we usually require a deposit before production. Contact our sales team for detailed terms.
Q: Can the mold produce caps of different diameters or thread types?
A: Yes. This mold is designed to be customizable. We can adjust cavity dimensions to match your bottle neck diameter (e.g., 18mm, 20mm, 24mm) and thread specifications. Please provide your bottle sample or drawing for evaluation.
Q: Is the mold compatible with standard injection molding machines?
A: Absolutely. We design the mold base and mounting dimensions to fit common injection molding machine platen sizes (e.g., 120T-200T for this 1×16 cavity mold). We can also adjust to your machine if you provide the specifications.
Q: How long does the mold last?
A: Under proper maintenance, the mold life is typically 1-2 million cycles. The actual life depends on the steel grade selected, cooling system, and maintenance frequency. We recommend regular cleaning and periodic inspection.
Q: What is the lead time for a custom mold?
A: Standard lead time is 25-40 working days from design approval, depending on complexity and current workload. Expedited services may be available upon request.
Q: Do you provide samples before mass production?
A: Yes. We can produce trial shots and send you cap samples for approval. Once you confirm the quality and dimensions, we proceed with mold delivery.
Q: What materials can the mold run besides PP and PE?
A: While optimized for PP/PE, the mold can also process other thermoplastic materials like PS, ABS, or PET if the design and cooling are adjusted. We recommend discussing your material with our engineers.
Q: Does the mold come with a warranty?
A: Yes. We provide a 12-month warranty covering manufacturing defects, excluding normal wear or misuse. Our technical team offers remote support and spare parts recommendations.
