The TH-141L Double Wheel Dyeing Machine is a compact, efficient, and precision-engineered device developed for high-quality oil edge dyeing of small leather items and detailed accessories. Designed with the unique requirements of artisans, crafters, and leather product manufacturers in mind, this model excels in working on intricate shapes, curved edges, circular contours, and hard-to-reach corners. Whether used in a leather workshop, craft studio, or boutique manufacturing line, the TH-141L offers superior performance, accuracy, and flexibility. Its lightweight and user-friendly construction ensures that both seasoned professionals and hobbyists can handle edge dyeing tasks with confidence and finesse.

Purpose and Design Philosophy

The TH-141L has been thoughtfully engineered for one critical purpose: to solve the challenge of applying dye evenly on small, curved, or unusually shaped leather goods. Traditional dyeing methods often fall short when it comes to small accessories such as wristbands, watch straps, zipper ends, and narrow leather bands. Uneven application, smearing, or missed spots are common issues when using manual brushes or generic edge painting tools. This is where the TH-141L Double Wheel Dyeing Machine shines. Its dual-wheel system allows for consistent dye distribution across various contours and corners. Whether the edge is rounded, slanted, or features a miniature corner transition, the machine maintains a uniform application with a smooth finish. It significantly improves both the aesthetic appeal and durability of leather products by ensuring every edge is treated with professional precision.

Key Features

Double Wheel Mechanism

The most distinguishing feature of the TH-141L is its dual-wheel system. The design incorporates two wheels that rotate simultaneously and work in tandem to apply dye evenly. This mechanism allows the machine to achieve consistent coverage on complex surfaces and edges, including tight curves and minute corners. Compared to single-wheel systems or hand tools, the double-wheel configuration provides better grip, control, and coverage, ensuring a flawless edge every time.

Precision Application for Small Items

This machine is ideal for fine work on small leather items. Products like leather keychains, wrist straps, watch bands, wallets, and decorative trims often have fine edges that require attention to detail. The TH-141L enables artisans to apply dye with surgical precision. Even delicate or intricate designs are easily accommodated by the machine’s fine-tuned controls and adaptive wheel movement.

Compact and Lightweight Design

Weighing only 2.2kg and measuring 420×180×90mm, the TH-141L is built for convenience. Its compact footprint allows for easy setup in small workshops, mobile studios, or home-based craft environments. It can be placed on any standard workbench or table without occupying much space. Moreover, its lightweight design means the machine can be easily transported, stored, or repositioned based on production needs.

Low Power Consumption

With a power rating of just 25 watts, the TH-141L is highly energy-efficient. It provides optimal performance without drawing excessive electricity, making it an eco-conscious and cost-effective solution for daily use. Despite its low energy usage, it delivers a powerful and consistent dyeing operation that matches or surpasses higher-wattage machines in its class.

Simple Controls and Easy Operation

The user interface of the TH-141L has been designed for ease of use. The machine features straightforward controls that allow the user to adjust wheel speed and dye flow with minimal effort. There is no complex calibration or setup required. Whether you are a beginner or an experienced professional, you can begin dyeing within minutes of powering the machine.

Minimal Maintenance Required

The TH-141L is built from high-quality materials and engineered to require minimal upkeep. The dyeing components are easy to clean, and the internal mechanisms are durable enough to handle frequent use without frequent servicing. Routine maintenance involves basic cleaning of the dye reservoir and wheels, making it suitable for busy production environments.

Safety and Stability

Despite its compact size, the machine maintains excellent stability during operation. The base is designed to minimize vibration, keeping the wheels aligned and ensuring consistent contact with the leather edge. Moreover, it operates at low heat, eliminating the risks associated with overheating or material damage during extended use.

Applications and Use Cases

Wristbands and Watch Straps

Watch straps and wristbands are often made from narrow strips of leather with curved edges. Dyeing them evenly can be challenging with manual tools. The TH-141L handles such tasks effortlessly, ensuring that each strap receives an even, smooth edge coating, enhancing both aesthetics and durability.

Leather Accessories

Leather accessories such as belts, pouches, tags, and decorative trims often feature various edge shapes and small corners. The machine’s double-wheel dyeing system adapts to these shapes seamlessly, allowing for consistent coverage even on layered or overlapping designs.

Zipper Tails and Pullers

Zipper pullers and tail ends are small but essential components in leather crafting. Their size makes them difficult to dye accurately by hand. The TH-141L can apply dye to these pieces with pinpoint precision, improving the visual consistency of finished products.

Wallets, Card Holders, and Key Cases

Wallets and card holders often require fine edge finishing for both functionality and aesthetic appeal. Using this machine ensures that each edge is treated evenly, resulting in a polished and professional finish that adds value to the product.

Craft Studio and Boutique Production

For leather craft studios and boutique manufacturers that specialize in limited-edition or customized leather goods, the TH-141L is an ideal addition. It supports flexible production without the need for bulky machinery or complicated configurations.

Educational and Training Use

Because of its simplicity and safety features, the TH-141L is also ideal for training environments, such as leathercraft schools or vocational programs. Students can quickly learn how to use the machine, develop a feel for edge dyeing techniques, and build confidence with professional tools.

Benefits of the TH-141L Double Wheel Dyeing Machine
