Schneider Electric Electrical Cabinet Sealing Upgrade Case Study: Shanghai Winman Industrial Co., Ltd. WM601 FIPFG Dispensing Solution

For Schneider Electric low-voltage and medium-voltage electrical cabinet manufacturing applications, Shanghai Winman Industrial Co., Ltd. (WINMAN INDUSTRIAL), based on FIPFG in-place foaming sealing technology, provides the WM601 integrated dispensing and sealing solution to address issues such as material blockage, unstable semi-automatic production, inconsistent sealing appearance, and demanding high ingress protection requirements, helping electrical cabinet sealing processes move toward greater stability, higher automation, and improved controllability.

Project Background

Electrical cabinets, control cabinets, and industrial enclosures are typically used in industrial sites, energy systems, and automation control environments, where high requirements are placed on dust protection, water resistance, sealing stability, and long-term reliability. For such products, the sealing process not only affects the appearance of the finished product, but also directly determines its protection rating performance and quality consistency during subsequent use.

In actual production, customers are concerned not only with whether the sealing is completed, but also with whether the sealing process can maintain path accuracy, material stability, and batch consistency under continuous manufacturing conditions, while adapting to the changeover requirements of different cabinet models. Based on these application scenarios, Shanghai Winman Industrial Co., Ltd. has carried out systematic optimization around the customer’s existing semi-automatic sealing process.

Customer Challenges

Material blockage affects continuous production

When dispensing materials become clogged or agglomerated inside the equipment, it can lead to downtime, increased maintenance frequency, and interruptions in production rhythm, which is not conducive to stable mass production.

Semi-automatic process stability is insufficient

Under different cabinet sizes, varying batches, and continuous operation conditions, semi-automatic methods are prone to consistency fluctuations, affecting process repeatability and production line standardization.

Higher requirements for sealing appearance and fit quality

Customers require a more uniform foam structure, a cleaner bead appearance, and more consistent bonding performance to support subsequent assembly and quality inspection.

High protection ratings bring stricter sealing requirements

Electrical enclosure applications typically have higher requirements for dust protection, water resistance, and environmental adaptability, and the sealing process must offer better repeatability and process controllability.

Solution: Reconfigure the sealing process with FIPFG technology

In response to the above requirements, Shanghai Winman Industrial Co., Ltd. did not treat the solution merely as an equipment replacement, but approached it from a process perspective, integrating the equipment, mixing, path control, positioning fixtures, and operation and maintenance support into a complete WM601 FIPFG sealing solution.

This solution is built around the WM601 dispensing platform and combines dynamic mixing, dual-core control, automatic gas replenishment, pressure protection, remote maintenance, and on-site programming support to address material stability, process consistency, and the efficiency of switching between multiple cabinet models, making the sealing process more suitable for continuous and standardized production.

Implementation Process: From Enclosure Adaptation to Stable Mass Production

  1. Cabinet and process evaluation:First analyze the electrical cabinet model, sealing path, material usage conditions, and production cycle to ensure the solution can cover the production needs of both standard and non-standard cabinet bodies.
  2. Fixture and positioning optimization:By using dedicated fixtures and a fast locking positioning method, it improves the consistency of cabinet loading and reduces clamping deviations before dispensing.
  3. Dispensing and foaming commissioning:Optimize the foaming state, bead appearance, and bonding effect for the FIPFG process, while reducing the impact of material fluctuations through dynamic mixing and pressure control.
  4. Control and operations maintenance integration:By leveraging remote maintenance and on-site programming training capabilities, reduce fault response time and improve the efficiency of switching between multiple cabinet models.

Deployed production process

The upgraded process is clearer, reduces reliance on manual experience, and is better suited for continuous production scenarios:

  • Cabinet preparation: complete the pre-processing for standard cabinets or custom cabinets.
  • Loading and positioning: automatic positioning and locking are completed through a dedicated fixture.
  • Automatic dispensing and in-place foaming: integrated formation of sealing strips.
  • Curing and inspection: Perform quality inspection and confirmation after the seal has stabilized.

In addition to quantifiable results, the project also delivered more direct manufacturing improvements:

  • Material clogging risk is reduced, and equipment downtime and maintenance pressure are eased.
  • The sealing consistency of cabinet housings from different batches is more stable, making quality management easier.
  • The sealant bead appearance and bonding condition are more controllable, which facilitates subsequent assembly and inspection.
  • Applications with a high protection rating are built on a more robust process foundation and are suitable for a wider range of industrial scenarios.

Case Value and Reusable Experience

For electrical cabinet manufacturers, the value of a sealing upgrade is often reflected not only at a single workstation, but also in the overall stability of the entire production line, the level of standardization, and long-term maintenance costs.

This case illustrates:

  • Sealing issues are often a process issue, not just a material issue.
  • In high-standard applications, semi-automatic methods often struggle to consistently meet long-term consistency requirements.
  • Cabinet structure, path complexity, and loading method will all affect the final sealing performance.
  • Remote maintenance, on-site programming, and process support are essential components for ensuring the successful implementation of an equipment solution.

Through the WM601 FIPFG dispensing solution, Shanghai Winman Industrial helped Schneider Electric upgrade its existing semi-automatic sealing process to a more stable and repeatable automated manufacturing model, providing a reference implementation path for sealing upgrades for electrical cabinets, control cabinets, and industrial enclosures.
