China Top 12 Silicone Cup Sleeves Manufacturers for B2B Wholesale

The global drinkware market is evolving rapidly. As we look toward 2026, the demand for stainless steel tumblers, glass water bottles, and ceramic travel mugs is no longer just about the vessel itself—it is about the customization, the grip, and the branding protection. This is where the humble, yet critical, silicone cup sleeve¹ comes into play.

For distributors and brand owners—especially those of you procuring for markets in North America and Europe—finding the right manufacturing partner in China is the difference between a profitable season and a logistical nightmare. I know the pain points: inconsistent wall thickness, flash marks on the parting lines, color bleeding, and the dreaded "shipping delay" email right before Christmas.

I am Aries Hua, owner of Silijoy. With over a decade of experience in silicone manufacturing here in Zhejiang, I have seen thousands of projects go from a CAD drawing to a shelf in a retailer’s shop. While I am confident in my own factory's capabilities, I also believe in transparency. The Chinese manufacturing landscape is vast, and depending on your specific volume, niche, or technical requirements, different factories offer different strengths.

To help you navigate your sourcing strategy for 2026, I have compiled a list of the top 12 silicone cup sleeve manufacturers in China. These companies represent the best in terms of reliability, quality control, and manufacturing prowess.

1. Silijoy (Zhejiang)

Location: Zhejiang Province
Website: https://silijoy.com
Best For: Medium to large distributors requiring high customization, strict QC, and turnkey service.

I’m putting Silijoy at the top of this list not out of vanity, but because I’ve built this business specifically to solve the problems that importers like you face. Located in Zhejiang, a premier manufacturing hub, we specialize in 100% full-cycle service.

We don’t just mold silicone; we act as your technical consultants. Whether you need a simple silicone bottom protector (tumbler boot) or a complex, 3D-textured insulating sleeve for a glass bottle, we understand the physics of silicone compression and LSR injection molding.

• Capacity: We support over 1,000 successful projects annually.
• Quality: We use only food-grade, LFGB-certified, and BPA-free materials. Every single sleeve is inspected before packing—no sampling, exactly 100% inspection.
• Why Us: We offer low MOQ for trial orders, free samples, and we are obsessed with on-time delivery. We know that if your shipment is late, you lose your selling window. We don't let that happen.

2. Dongguan Hambo Silicone Technology

Location: Dongguan, Guangdong
Best For: High-volume consumer electronics accessories and standard cup sleeves.

Dongguan is often called the "World's Factory," and Hambo is a staple there. They have been in the game for a long time and have a massive production footprint. They are excellent if you have a very standardized product and need massive volume (hundreds of thousands of units) where price per unit is the only metric that matters. Their experience in phone cases translates well to cup sleeves, ensuring decent fit and finish.

3. Xiamen Better Silicone Rubber Co., Ltd.

Location: Xiamen, Fujian
Best For: Liquid Silicone Rubber (LSR) and high-precision medical-grade parts.

If your cup sleeve requires extreme precision or is part of a baby bottle system that requires medical-grade certification² above and beyond standard LFGB, Xiamen Better is a strong contender. Xiamen is a hub for high-tech LSR injection molding. While their pricing is typically higher due to expensive tooling and machinery, the lack of flash (excess material) and the high transparency capability of their silicone is impressive.

4. Shenzhen Zehui Rubber & Plastic Products

Location: Shenzhen, Guangdong
Best For: Promotional gifts and quick-turnaround novelty sleeves.

Located in the fast-paced city of Shenzhen, Zehui is great for promotional merchandise. If you are a brand looking for 50,000 low-cost sleeves for a marketing event or a trade show giveaway, they are very agile. They specialize in multi-color printing and unique, fun shapes. However, for long-term durable goods for high-end retail, you will need to specify your quality requirements very strictly.

5. Huizhou Melikey Silicone Product Co., Ltd.

Location: Huizhou, Guangdong
Best For: Baby products and sensory-friendly textures.

Melikey is famous in the teething toy industry. Because they are set up for baby products, their facility cleanliness and material safety standards are incredibly high. If you are designing a cup sleeve for a toddler's distinct sippy cup or a hydration vessel for the nursery market, their expertise in "soft-touch" silicone is unmatched. They are rigorous about FDA and CE compliance.

6. Ningbo Tensor Import & Export (Manufacturing Partner)

Location: Ningbo, Zhejiang
Best For: Logistics-heavy orders and mixed container loads.

Ningbo is home to one of the world's busiest ports. Factories in this area, like Tensor's partner network, have a massive logistical advantage for North American buyers. If you are sourcing not just sleeves, but also the bottles, lids, and packaging, a Ningbo-based partner can consolidate these effectively. They are less of a "boutique" designer and more of a supply chain powerhouse.

7. Guangdong T&K Silicone

Location: Dongguan, Guangdong
Best For: Complex branding, labels, and patch-style sleeves.

T&K specializes in heat transfer labels and intricate silicone branding. If your design involves a cup sleeve that looks like a tactical gear patch, or requires very detailed raised logos (embossing) with contrasting colors, T&K has the specialized equipment to do this. They treat silicone sleeves almost like fashion accessories, which is a growing trend for 2026.

8. Fujian Huitai Technology

Location: Quanzhou, Fujian
Best For: O-Rings and sealing integration.

Sometimes a sleeve isn't just a sleeve; it connects to the lid or acts as a seal. Huitai has a background in industrial sealing solutions. If your design is a "unibody" concept where the grip sleeve also functions as a waterproof gasket or has integrated O-rings, their engineering team is very strong. They understand tolerance stacks better than most promotional gift factories.

9. Shenzhen Hongyi Silicone

Location: Shenzhen, Guangdong
Best For: Odd shapes and highly creative designs.

Do you have a bottle shaped like a dumbbell or a fruit? Hongyi is known for taking on weird, difficult mold structures that other factories reject. They have a very capable R&D team for mold making. The trade-off is often a longer lead time for tooling, but if your product is unique, they are a solid choice for realizing complex geometries.

10. Shanghai Sili Cool Industry

Location: Shanghai
Best For: Corporate gifts and premium packaging integration.

Being in Shanghai, this manufacturer is very attuned to Western business practices and high-end presentation. They are excellent if you need your silicone sleeves kitted into luxury gift boxes. Their cost structure is higher due to their location, but their project management communication is usually top-tier, catering to major multinational corporations.

11. Suzhou Yingte Precision

Location: Suzhou, Jiangsu
Best For: Overmolding (Silicone over Plastic/Metal).

If your sleeve is not removable, but rather permanently bonded to the cup (overmolding), you need a factory like Yingte. Overmolding requires precise temperature control and specific substrates. While many factories claim to do this, Yingte specializes in bonding silicone to hard plastics and metals, ensuring the sleeve doesn't peel off after a few dishwasher cycles.

12. Zhejiang Bopai Intelligent Technology

Location: Zhejiang Province
Best For: Automation and massive scale consistency.

Another neighbor in my province, Bopai focuses on automation. They have invested heavily in automated compression molding machines. This reduces labor costs on massive orders. If you are looking to place an order for 500,000 units with very simple geometry, their automated lines provide excellent consistency and competitive pricing, though they are less flexible with low-volume custom work compared to Silijoy.

Key Factors for B2B Buyers

When choosing from this list, you must look beyond just the price tag. In my 10 years of manufacturing, I have seen buyers switch factories over a $0.02 difference, only to lose thousands of dollars when a batch arrives smelling of cheap curing agents or with visible parting lines.

1. Material Transparency: Ensure your supplier uses Dow Corning, Wacker, or equivalent high-grade raw silica. Ask for the raw material certification, not just the finished product cert.
2. Tooling Ownership: At Silijoy, we guarantee that if you pay for the mold, you own the mold. Many factories will re-use your custom design for other clients. Make sure this is clear in your contract.
3. Communication: You need a partner who replies in hours, not days. We understand the B2B pressure.

Conclusion

Selecting the right partner for 2026 requires balancing cost, quality, and communication. While huge factories in Dongguan offer scale, and specialized labs in Xiamen offer medical precision, Silijoy offers the optimal balance for brand owners focusing on drinkware. We combine the agility of a design-focused team with the robust capacity of a Zhejiang manufacturing hub. We don't just sell sleeves; we sell the assurance that your product will arrive on time and perfect. Contact me today for a free sample and let’s discuss how we can elevate your product line.
