Application Case of CC-3A-3500 Rotational Molding Machine for a Client in Bangladesh

1. Market Background: Increasing Demand for Large Plastic Products, Traditional Equipment Falling Short

In recent years, Bangladesh has experienced a rapid development in infrastructure, leading to a significant rise in demand for plastic products:

• The municipal and industrial sectors require a large number of PE water towers, chemical storage tanks, and septic tanks.
• The market demand for large water towers and storage tanks has also surged, but existing enterprises struggle to meet this demand.

Many local factories still use small-scale and traditional manual production methods. Faced with increasing customer requirements and varying product specifications, the limitations in production capacity and consistency of traditional rotational molding equipment have become apparent.

2. Customer Pain Points: Unable to Meet Large-Scale Production and Diverse Demand

The client we collaborated with in Bangladesh specializes in the production of water towers and storage tanks. Before the project launch, they faced three main issues:

1. Limited Molding Size
   The existing equipment could only effectively produce tanks around 4000L, while market orders were steadily increasing.

2. Insufficient Production Capacity
   The old equipment's single-station design limited production efficiency, making it difficult to meet the strict delivery timelines for municipal projects.

3. Challenges with Product Consistency and Energy Consumption
   Due to inconsistent temperature and time controls, variations in product appearance and wall thickness persisted, leading to higher energy consumption and difficulty maintaining quality.

The enterprise manager clearly stated: “We need a rotational molding machine capable of producing 7000L products with efficient production capacity and stability.”

3. Solution: CC-3A-3500 Rotational Molding Machine, Occupying 18×11×5.5m, Capable of Producing Up to 7000L

After thoroughly understanding the client's factory structure, existing mold sizes, and target products, we configured and exported a CC-3A-3500 rotational molding machine. Our engineers were dispatched to Bangladesh for installation, debugging, and operational training. Key points of the solution include:

• Matching Equipment Size and Capacity
  The machine occupies approximately 18×11×5.5 m, fitting seamlessly into the client's existing factory and allowing for mold replacement and material handling space; the effective molding area can accommodate a maximum of 7000L product needs.

• Rotational Structure Enhancing Mold Utilization
  The machine features a rotational molding design, with heating, cooling, and demolding stations working in a cyclical manner, increasing mold utilization within the same production cycle.

• Precision Control for Consistent Products
  By implementing unified temperature, time, and speed control parameters, we helped the client establish standard processing recipes for various product specifications, ensuring product consistency.

• On-Site Service and Training
  Our engineers completed the basic installation, calibration, and testing of the equipment while providing training on daily operations and safety protocols for the operators.

The CC-3A-3500 rotational molding machine has been successfully installed and is now in production.

4. Customer Feedback: Smooth Production of Large Capacity Products, Increased Confidence in Scheduling

During the initial phase of production, the client provided positive feedback regarding the equipment:

1. Large Capacity Products Can Be “Truly Achieved”
   Previously, they could only produce tanks around 4000L; now, they can confidently accept orders for 7000L water towers and storage tanks.

2. Controlled Production Capacity and Scheduling
   The rotational structure allows for the arrangement of more molds in the same shift, significantly compressing the production cycle. Scheduling has transformed from potential delivery concerns to a more rational arrangement of shifts.

3. Improved Product Consistency and Ease of Operation
   Utilizing the processing recipes we developed, operators can achieve consistent wall thickness and appearance in products. The new equipment is easier to operate than expected, with both new and veteran employees able to operate it independently after training.

The client’s manager stated: “With the CC-3A-3500, we have greatly increased our confidence in producing 7000L water towers in the Bangladesh market, and we will consider expanding the use of molds on the same platform in the future.”

5. Conclusion: Who is the CC-3A-3500 Most Suitable For?

Based on the experience from this project in Bangladesh, the CC-3A-3500 rotational molding machine is particularly well-suited for:

• Factories planning to expand into the production of large capacity water towers, storage tanks, and septic tanks up to 7000L.
• Enterprises currently using small or single-station equipment, looking to improve production efficiency with a rotational molding structure.
• Customers whose factory space can accommodate approximately 18×11×5.5 m and wish to support multiple molds on a single platform.

For similar customers, a prudent upgrade path includes:

• Clearly defining the maximum target product specifications (e.g., 7000L) and future product plans.
• Selecting a model of rotational molding machine (e.g., CC-3A-3500) that matches the factory layout while reserving space for mold expansion.
• Establishing processing recipes during the equipment installation phase to streamline subsequent mass production for easier management.

This approach not only enhances production capacity but also boosts overall efficiency in the rotational molding industry.
