High-speed, premium-grade two-piece cans and metal bottles engineered for Detroit's dynamic craft brewery and beverage manufacturing lines.
Founded in 1992, Sunrise Group Co., Ltd. (Stock Code: 002752) has established itself as an industry leader in metal packaging, beverage filling, supply chain management, and smart packaging services. With over 33 years of hard work, the Group maintains 31 production bases across 28 cities in China and Southeast Asia, including Cambodia, Indonesia, and Vietnam.
By leveraging state-of-the-art metal forming systems and advanced internal lacquering techniques, we provide Detroit’s beverage manufacturers, microbreweries, and contract packers with high-barrier, sustainable, and lightweight two-piece aluminum cans. Whether you are packaging carbonated soft drinks, functional energy drinks, nitrogen-infused cold brews, or Michigan's renowned craft beers, Sunrise Group offers high-volume efficiency alongside personalized local supply support.
Healthier consumption, better life through smart and clean packaging designs.
To become one of the most valuable service providers in the global FMCG industry.
Integrity, Quality, Innovation, Commitment, and Win-win outcomes.
Detroit, Michigan—historically the engine room of American automotive ingenuity—is currently experiencing an industrial renaissance driven by diversified manufacturing, advanced food processing, and a booming craft beverage sector. The demand for two-piece aluminum cans within the Great Lakes region has scaled exponentially. As regional consumption shifts toward sustainable, infinitely recyclable packaging, local beverage brands require secure, high-yield supplier channels that can deliver both quantity and quality.
The Midwest market presents unique logistical demands. Local contract packaging (co-packing) facilities and craft beverage brands face severe supply bottlenecks when relying solely on regional domestic packaging giants. This is where Sunrise Group's double-pronged approach—combining mega-scale manufacturing capabilities in Southeast Asia and China with specialized logistics management—enables Detroit-based manufacturers to eliminate line stoppages, mitigate local raw material shortages, and maintain high margin controls.
"As Detroit's beverage producers adapt to fast-moving consumer demands, the choice of a metal packaging partner must extend beyond proximity. It requires an engineering partner capable of delivering consistent metallurgical thickness, clean flange finishes, and certified BPA-Non-Intent (BPA-NI) internal liners."
The modern two-piece aluminum can is a marvel of precision metallurgy. In contrast to three-piece cans, which consist of a rolled body, bottom end, and top end, the two-piece can merges the body and bottom into a single seamless piece. This structure is achieved through the Draw and Wall Ironing (DWI) process.
At Sunrise Group, our manufacturing lines utilize high-grade aluminum alloys, primarily Alloy 3104 for the can body (offering exceptional drawability and tensile strength) and Alloy 5182 for the easy-open ends (providing rigid structure and clean scoring dynamics). The DWI technical route involves several critical stages:
| Processing Phase | Technical Action | Quality Control Parameters |
|---|---|---|
| 1. Cupping & Drawing | Coiled aluminum sheet is lubricated, fed into a cupping press, and stamped into circular cups. | Wall thickness uniformity within ±0.002 mm. |
| 2. Ironing & Doming | The cup is pushed through progressively smaller ironing rings, thinning the walls while forming the dome base. | Optimized dome depth for internal pressure resistance up to 6.2 Bar. |
| 3. Necking & Flanging | The open top is progressively necked inward to match the chosen end size (e.g., 202 or 206 ends) and flanged outward. | Flange width tolerance within tenths of a millimeter to ensure hermetic double seams. |
| 4. Surface Inner Coating | Electrostatic airless spraying applies food-grade BPA-NI epoxy or acrylic coatings to protect beverage flavor. | 100% pinhole detection via high-voltage conductivity testers. |
Global logistics can present challenges for purchasing managers in the Midwest. At Sunrise Group, we address these challenges through structured shipping pathways, optimized container stacking, and warehousing partners situated near major Midwestern transit corridors. Through our 31 production bases, we ensure that raw material spikes in one region do not dictate the price or delivery schedule of your order.
Additionally, our equipment profile relies on globally renowned manufacturing technology: Swiss Soudronic systems, German KAMPF and Hinterkopf lines, British Crabtree printing presses, Japanese Fuji printers, and American STOLLE and BELVAC forming machinery. This ensures our products are fully compatible with your existing high-speed fillers (such as Krones, CFT, or Wild Goose canning lines) in Detroit and surrounding Great Lakes cities.
