What are the anti-slip bottom treatment methods for custom metal tins?

July 9, 2025/in News /by admin

When we design and manufacture custom metal tins for our clients, one of the most popular features is non-slip protection on the base of the can. Non-slip bases prevent cans from sliding on smooth countertops, reducing the risk of accidental tipping, while also enhancing the perceived quality in retail displays and home use. We incorporate everything from rubber pads to embossing to strike a balance between functionality and aesthetics. A comprehensive approach ensures that each custom tin remains firmly in place, regardless of the environment or usage scenario.

Integrating Molded Rubber Pads into Custom Metal Tins for Enhanced Traction

One of the most effective non-slip treatments I use on custom metal tins is to integrate molded rubber pads directly into the base of the can. We use 40 Shore A EPDM rubber pads, which provide an ideal balance of grip and durability, and we bond them with a high-strength, weather-resistant adhesive that can withstand repeated handling and temperature fluctuations. This design positions the rubber pads to align with the can’s weight distribution, typically placing three to four pads per base to ensure even support and maximize contact area. During production, I use precision CNC-cut jigs to apply adhesive and place rubber pads evenly across thousands of products. The resulting custom metal tins exhibit superior anti-slip properties on glass, marble, and laminate surfaces, thereby enhancing both safety and the user experience.

Applying Silicone Anti-Slip Coating to Custom Metal Tins

Another anti-slip solution we use is a liquid silicone coating on the bottom of a custom metal tin. The benefit is that in addition to providing a soft touch, the silicone layer absorbs micro-vibrations and reduces noise when the can is moved. This makes it ideal for high-end gift cans where appearance and user comfort are essential. I choose food-safe, UV-curable silicone formulas that cure in 60 minutes at room temperature, increasing the yield of our production lines. By controlling the coating thickness (typically 0.5 to 1 mm), a uniform matte effect is achieved, which can also blend seamlessly with printed or painted tin surfaces. Our quality inspections include peel testing and coefficient of friction measurements to ensure that each custom tin maintains stable contact on dry and slightly damp countertops.

The embossed pattern on the bottom for enhanced mechanical grip

In addition to adding material, I also take advantage of the can’s structure by embossing non-slip patterns directly on the metal base. I design raised dots, ribs, or geometric textures on the base during the stamping process. The embossed pattern thus increases friction by forming micro-anchor points that grip the underlying surface. The core of the process involves programming the hydraulic press to consistently emboss to a depth of 0.2 mm, ensuring a crisp pattern without compromising the structural integrity of the can. This approach eliminates the need for additional parts or adhesives, simplifies the assembly process, and reduces the potential for adhesive failures. Customers appreciate that our metal cans retain a clean, unchanging visual profile while still having the strong non-slip properties inherent in the can itself.

Enhanced surface grip with textured roller embossing

For high-volume custom tin cans, I typically emboss the bottom with a textured roller before sealing. For example, a quick-change rotary embossing roller can emboss a dot or crisscross pattern in a single pass. Additionally, this continuous process integrates seamlessly into our existing canning lines, with no additional handling steps required. I optimized roller hardness and pattern spacing to achieve a coefficient of friction of over 0.6, surpassing industry benchmarks. Because the system performs this process inline, turnaround times remain fast, and the embossing gradually wears away while maintaining non-slip properties even after hundreds of cleaning cycles. This approach to custom tin cans ensures both high production efficiency and consistent non-slip performance.

Adhesive Non-Slip Feet for Modular Flexibility

Finally, for packaging applications that require removable or custom non-slip features, I offer adhesive rubber feet that the customer can install after production. In addition to the non-slip feature, these peel-and-stick feet allow the end user to replace worn pads as needed. As a result, the can maintains performance throughout its lifecycle. I source premium thermoplastic elastomer feet and utilize a pressure-sensitive adhesive rated for a 5 kg shear load, ensuring that each custom kit includes alignment guides to ensure that square, hexagonal, or round feet are correctly placed, thereby enhancing functionality and final appearance. This modular solution is ideal for limited-edition packaging or scenarios that require on-site customization, offering customers maximum flexibility and customization options.

It provides you with a better anti-slip treatment for your bottom.

Effective anti-slip bottom treatment for custom metal tins combines material science, precision manufacturing, and user-centered design. I integrate molded rubber pads, liquid silicone coatings, embossed textures, texture rolling, and adhesive foot designs so that each method can be tailored to different production volumes, aesthetic requirements, and end-use scenarios.

How to implement the stack lock lid design in custom metal tins?

June 16, 2025/in News /by admin

The stack-lock lid design meets the reliability, ease of use, and unique appearance required by the product. By incorporating a precisely designed locking mechanism into a custom metal tin, a seal that is both secure and convenient to use can be created. In addition, the stack-lock lid does not require a separate lid or tape, which enhances the convenience and user experience. Implementing this design in a custom metal tin requires close cooperation with the tin can manufacturer. For us, this process involves determining the lid geometry, selecting compatible materials, developing molds, conducting quality testing, and finally, implementing the design in custom metal tins through post-production.

Geometry and Locking Mechanism of Custom Metal Tins Lids

To implement the stack-lock lid design in a custom metal tin, we first need to determine the precise geometry of the lid. Interlocking beads or flanges around the can mouth and lid typically form the locking mechanism, snapping together when pressed. When designing, we need to determine the bead height, flange angle, and tolerance range. During manufacturing, stamping or rolling dies form the lid’s flange, while stretching and trimming processes shape the can body to create a matching flange. By determining these dimensions, we can ensure that the lid and the can body lock with a constant force, yet the force is gentle enough for customers to open without the need for tools.

In the design process, our engineers typically create prototypes of multiple flange shapes and test the insertion force and holding strength of each flange. To ensure that your custom metal tins have a perfect balance between ease of use and security.

Material Selection for Stacking Lock Caps

When using stacking lock caps in custom metal tins, we use tinplate as the primary material. Due to their excellent formability and strong locking performance, they are ideal for larger tins or products that require enhanced sealing integrity. During the manufacturing process, the hardness of the metal affects the performance of the locking bead. The softer hardness makes the flange easier to bend and snap into place, while the harder temper provides greater holding force but requires more precise locking bead geometry. Therefore, choosing equal hardness tempers for your custom tins can achieve the best balance between manufacturability and locking strength.

Tooling and Production of Custom Metal Tins

For custom tin cans with overlapping lock lids, we use specialized stamping dies, one for the can body flange and one for the lid edge. During production, we perform a draw-draw-trim process on the can body, followed by a separate lid stamping operation. After stamping, the lid and can body enter a ball rolling machine to form the final radius on the flange edge, ensuring a smooth joint. For consistency, statistics are implemented to track the size of the trackball and the insertion force from batch to batch. By monitoring these indicators, deviations can be detected and press settings adjusted promptly. Ensure that your custom cans have a consistent locking performance from the first production run to the last.

Quality Control and Seal Performance Testing

First, technicians perform a pull-off test to measure the force needed to remove the lid, verifying it meets the target retention strength. Next, they drop a whole can from different heights to simulate shipping shocks. Environmental testing reveals how extreme temperatures affect lid retention and metal expansion. Using pressure decay testing in sealed cavities to detect micro leaks is especially important when packaging powdered or moisture-sensitive products. Additionally, we document these test results in our quality management system to ensure traceability and accountability. By integrating rigorous testing protocols, we provide the reliability of displaying custom tins.

About surface treatment and branding design

We often use powder coating, offset printing, or UV full-color lithography to display logos and product information in the surface design of custom metal tins. When planning these surface treatments, we ensure that the coating thickness does not change the bead size. Additionally, we select the corresponding primer and topcoat chemistries based on the product’s storage conditions. For example, food-grade coatings prevent oil migration when packaging mixed spices, while anti-scratch coatings protect high-flow cosmetic tins. At the same time, you can also add local UV or embossing to the edge of the lid to create tactile feedback, coordinating functional design with visual appeal.

Achieving the perfect stack lock lid design

Achieving the stack lock lid design in custom metal tins will require precise engineering design, high-quality materials, and thoughtful branding. During the production process, the appropriate metal alloy and tempering temperature are selected to lay the foundation for reliable locking performance. We use professional molds and strict quality tests to ensure each tin can snaps securely and stays sealed under all conditions.
