High-Speed Soap Stamping Machine with Crank Drive for Efficient and Low-Noise Production

In the soap industry, stamping machines play a vital role in the production process, particularly in the shaping, embossing, and branding of soap bars. These machines allow manufacturers to automate the production of soap with precision and consistency, ensuring uniformity in size, shape, weight, and the application of decorative elements or logos.

Whether you're scaling a production line or upgrading outdated equipment, precision and reliability are key to maintaining product quality and profitability. At JIANGSU SOHO HONRY WUXI CO., LTD., we provide cutting-edge equipment that delivers exactly that.

Our high-speed soap stamping machine with crank drive has been specially designed to meet the demands of modern soap production facilities. Developed as an upgrade from the widely used XG-01 model, this improved stamper integrates a crank connecting rod mechanism, replacing traditional cam transmission systems to offer greater stability, reduced vibration, lower noise, and significantly enhanced production efficiency.

Why Choose a Crank-Driven Soap Stamper?

Traditional cam-based soap stamping machines, while effective, often generate high levels of vibration and noise over time. This not only contributes to faster wear and tear on machine components but can also reduce the consistency of soap bar shapes—especially at higher speeds.

Our crank-driven soap stamper solves this problem by adopting a more robust mechanical structure. The crank connecting rod mechanism delivers smoother, more consistent reciprocating motion, eliminating erratic movements and producing uniform, high-quality soap bars.

Optimized for High-Speed, High-Volume Production

With a production capacity of 80 to 120 pieces per minute, our machine is engineered for speed without compromising on precision. Whether you are stamping 50g or 250g soap bars, the high-speed soap stamping machine handles a wide weight range.

Reciprocating stroke: 115mm

Soap weight range: 50–250g

Power consumption: 3kW (YCT-160-4B)

Speed regulation: 115–1150rpm

Overall dimensions: 3560 × 1410 × 1135 mm

Total weight: 1950kg

These specifications demonstrate the machine’s capability to meet the output demands of small, medium, and large-scale soap production lines.

Key Technical Advantages

1. Crank Mechanism for Stability and Durability

The most notable improvement in this model is the replacement of cam drive with a crank connecting rod system, which greatly reduces machine vibration and noise during operation. This results in better long-term reliability and enhanced worker safety and comfort.

2. Electromagnetic Speed Regulation

Our soap stamping machine features electromagnetic speed control, allowing the operator to adjust the stamping speed smoothly to match upstream production (typically the vacuum plodder). This synchronization helps avoid bottlenecks and maintains a consistent production rhythm.

3. Reciprocating Long Bar Stamping

Designed for long bar reciprocating stamping, the machine ensures precision molding and efficient shaping for a variety of soap formats. The reciprocating structure improves mold contact and results in cleaner edges and more defined logos or impressions.

4. Seamless Integration with SDJ Duplex Vacuum Plodder

This soap stamping machine can be seamlessly connected with SDJ Duplex Vacuum Plodder, forming a continuous automatic soap production line. Together, they provide a complete solution from extrusion to final stamped bar, significantly reducing manual labor and improving line automation.

Designed for Industrial-Grade Use

This industrial soap stamping equipment is built with a durable steel frame and high-precision mechanical parts, ensuring long-term use even under continuous-duty conditions. The rugged build allows for 24/7 operation with minimal maintenance requirements, giving manufacturers peace of mind and higher ROI.

In addition, the easy-to-access layout allows for fast maintenance and mold replacement, reducing downtime and increasing operational uptime.

How Our Soap Stamping Machine Works

After soap billets are extruded from the vacuum plodder, they are conveyed via a belt directly into the stamping unit. The soap billet enters the mold cavity, and through the reciprocating crank motion, the soap is stamped into the desired shape. Finished soap bars are collected manually or integrated into a packaging line for automatic sorting.

This simplified workflow ensures high throughput while maintaining high-definition stamping results on every bar.
