Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. As a specialized manufacturer since 2017, we bring years of expertise in precision mold making to every product we deliver. Our Custom Plastic Cap Injection: 1*24 Cavities Hot Runner, Glossy Finish mold is engineered to produce high-quality, glossy plastic caps with unmatched efficiency. This mold is designed for industries requiring consistent, high-volume production of caps for beverages, cosmetics, pharmaceuticals, and more. Combining advanced hot runner technology with a glossy surface finish, we help you achieve superior product aesthetics while minimizing cycle time and material waste.
Our mold is built on a 1x24 cavity layout, meaning each injection cycle produces 24 identical caps simultaneously. The hot runner system ensures precise temperature control and balanced melt flow, reducing scrap rates and maintaining part quality across all cavities. The glossy finish is achieved through meticulous polishing and mold surface treatment, giving your caps a premium look that stands out on the shelf. With our TS16969 certified production process, you can trust that every mold meets rigorous quality standards.
Key Features & Technical Specifications
- High Cavity Count (1x24): Maximizes productivity per cycle — ideal for medium to high-volume production runs.
- Hot Runner System: Eliminates runner waste, reduces cycle time, and ensures uniform filling of all cavities.
- Glossy Surface Finish: Achieved through fine polishing of cavity surfaces (RA ≤ 0.05 μm), resulting in caps with excellent visual appeal and smooth texture.
- Customizable Design: We can adapt the mold to produce caps of various diameters, heights, thread designs, and logos as per your requirements.
- Durable Mold Steel: Constructed from premium grades (e.g., S136, H13, 718H) for long mold life and resistance to wear and corrosion.
- Precision Cooling System: Optimized cooling channels ensure uniform temperature distribution, reducing warpage and cycle time.
- Easy Maintenance: Interchangeable cavities and inserts allow quick replacement and servicing.
- Quality Assurance: Every mold undergoes strict dimension inspection and trial runs before delivery.

Why Choose This Mold for Your Caps?
The 1x24 cavity hot runner design offers a perfect balance between initial tooling investment and per-part cost. For medium to high volumes, this configuration reduces mold cost per cavity compared to higher cavity counts, while still providing excellent output. The hot runner system eliminates cold runner scrap, saving material and handling time. Additionally, the glossy finish gives your caps a luxurious appearance that can differentiate your brand in competitive markets such as beverages, cosmetics, and household chemicals.
Our mold is designed to run on standard injection molding machines, making integration easy for existing production lines. The precision cooling channels ensure fast heat dissipation, reducing cycle time and improving productivity. Each mold is thoroughly tested in our workshop before shipment, so you receive a ready-to-run tool. Furthermore, we offer full after-sales support, including mold maintenance advice and spare parts supply.

Frequently Asked Questions (FAQ)
1. What materials can this mold produce caps from?
Our mold is designed to run a wide range of thermoplastics, including PP, PE, HDPE, LDPE, PET, ABS, and PS. For glossy finish, materials with good flow and low shrinkage are preferred. We can adjust mold design for specific materials upon request.
2. How long does it take to manufacture this mold?
Typical lead time for a 1x24 cavity hot runner mold is 30–45 days from design approval. This includes design, machining, heat treatment, assembly, and trial testing. Rush orders can be arranged with additional charges.
3. Can the glossy finish be customized to different levels?
Yes, we can achieve various gloss levels (high gloss, matte, textured) based on your requirements. The standard glossy finish is mirror-polished to RA ≤ 0.05μm. Other surface finishes are available as options.
4. Do you provide mold testing and sample caps?
Absolutely. After mold completion, we conduct trial runs on our own injection machines and provide sample caps (typically 100–200 pieces) for your approval. A video of the mold in operation can also be shared.
5. What is the warranty period for this mold?
We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Warranty covers issues like broken components, excessive wear due to material defects, or poor workmanship. Normal wear and tear from use is not covered.
6. Can the hot runner system be replaced with a cold runner?
For this specific design, we utilize a hot runner to maximize efficiency. However, if you prefer a cold runner system for lower initial cost or specific material requirements, we can redesign the mold accordingly. Please discuss with our sales team.
7. What is the minimum order quantity (MOQ) for custom molds?
We accept single mold orders with no MOQ. However, for special pricing or bulk orders, we offer discounts. Please contact us for a quote.
8. Do you offer mold approval before mass production?
