Rubber stamps' feature upgrades vivify line

New designs are easy to grip, and boast improved leakage resistance and security features.

Rubber stamp suppliers in China are developing ways to boost product differentiation.

Improving user comfort is one strategy. In this regard, makers are refining handle shapes for easier grasping. New designs from Shenzhen Wanxi Technology Co. Ltd, for instance, have concave parts serving as thumb rests.

Manufacturers are elevating leakage resistance as well.

Select preinked models from Guangzhou Suda Stamper Co. Ltd boast dies that leave imprints only after being dipped in water. This feature helps avoid unnecessary staining during storage.

Many of the latest versions are also fitted with transparent windows or lids for viewing stamp content. Traditionally, items have labels to indicate patterns and details.

Handles and housings are being made with multiple and contrasting shades for heightened visual appeal. Novelty shapes are likewise gaining prominence.

Suppliers are also incorporating anti-counterfeiting features. Dongguan Huifeng Commercial Co. Ltd offers designs yielding invisible marks. These are marketed with a special film for reading such impressions. For the security attachment, the Guangdong province-based maker charges an additional $15,000 per order.

To ensure safety, the majority of rubber stamp manufacturers are obtaining EN 71-3 and ASTM D4236 certification for their products. Pieces from Guangzhou Suda also comply with EN 71-9 requirements. In addition, the company is releasing food-grade versions that pass Japan's ST2002-3 standard. Available only on request, these designs are priced 10 percent higher than regular items.

Apart from finished pieces, most rubber stamp specialists in China produce materials and components in-house. This allows companies to develop manufacturing inputs that perform better than those of industry rivals.

To illustrate, rubber, which is a key material for dies, should normally be kept refrigerated to maintain its elasticity. Some makers, however, have created variants that can be stored under room temperature.

Inputs from Shenzhen Wanxi are able to handle this condition for more than a year without losing their elastic property. Guangzhou Suda has versions that can last for six months, while those adopted for its industry-use stamps are still employable even after five years.

Ink features are being enhanced as well. A number of suppliers have developed variants that can be utilized on different surfaces. The shelf life is also lengthened, with some able to resist drying for up to six months. A preinked rubber stamp from Guangzhou Suda adopting such ink is priced at $4.50. Models using regular types go for $1.50.

Rubber stamps selection

China's selection of rubber stamps includes self-inking, preinked and traditional designs. Only the last category comes with a separate pad.

Models of the first type have built-in components that are refillable and available in various colors. These releases are suitable for high-volume utilization on different surfaces, and are often the most expensive. Quotes start at $1.

For preinked versions, the pigment is infused into the die during production. Stamp patterns are often machine-engraved or press-molded. Although pieces yield crisp and clean imprints, models are not designed for rapid and heavy usage as they necessitate a period of reinking after several impressions. Prices range from $0.10 to $0.30.

In terms of materials, ABS and PP are the most common options for housings and handles. Rubber, meanwhile, is the top choice for dies.

Some toy versions even have casings and grips in EVA or wood, including beech and maple. The first input, together with TPE and silicone, is also utilized for dies. Children's models from Guangzhou Suda boast handles in cherry, oak and beech. Priced 60 percent higher than plastic versions, products come with a colorful painted finish. The supplier also offers alternatives in faux crystal. Items go for $6.

As regards shapes, round, rectangular, square and arched designs are popular. Many toy stamps are likewise available in animal, flower, egg and other novelty contours.

To facilitate storage, makers are launching children's models with detachable die plates. Such parts are attached to the handles and shells via magnets or pressure-sensitive adhesives.

Stamp content is typically buyer-specified. The common options are dates, signatures, and other business- and office-use texts. Holiday, congratulatory, thanking and romantic themes are offered as well. For toy versions, cartoon character, number, alphabet, floral and fruit motifs are popular.
