Latest Infrared Welding System for Pleated Filter Cartridges Production
In the filtration industry, the quality and precision of manufacturing processes directly impact the performance and reliability of filter cartridges. One of the most critical steps in pleated filter cartridge production is the welding of end caps, which must form a strong, leak-proof, and chemically resistant bond with the filter media. In recent years,
infrared (IR) welding technology has become the preferred solution for high-end applications. Among the industry leaders,
INDRO FILTER MACHINE has introduced a breakthrough system—
Model NO SIIC-M025—which represents the
latest infrared welding system for pleated filter cartridges production.
This article explores the significance of infrared welding in filter cartridge manufacturing, the advanced features of the SIIC-M025 model, and why INDRO is recognized as a trusted
filter cartridge end cap welding equipment manufacturer across the globe.
1. The Role of End Cap Welding in Filter Cartridge Production
Pleated filter cartridges are widely used in critical industries such as pharmaceuticals, food and beverage, water treatment, and electronics. These cartridges rely on plastic end caps—typically made of polypropylene (PP), ABS, or other thermoplastics—to seal the ends of the pleated filter media and secure the internal core or cage.
The end cap welding process is vital for:
- Ensuring leak-tight operation under pressure
- Preventing bypass of unfiltered liquids
- Providing structural integrity and support
- Ensuring chemical compatibility during use
Inadequate or inconsistent welding can result in filter failure, contamination, and product recalls. That’s why leading filter manufacturers turn to modern
filter cartridge end cap welding equipment with infrared heating technology for consistent, high-strength welds.
2. Why Infrared Welding?
Traditional hot plate welding and ultrasonic welding methods are still used in some settings, but they have limitations:
- Hot plate welding involves contact-based heating, which can introduce contaminants and degrade heating elements over time.
- Ultrasonic welding is fast but less effective on large-diameter components or complex geometries.
Infrared welding, in contrast, offers significant advantages:
- Non-contact heating avoids physical contamination and reduces wear
- Precise heat control allows for clean, uniform welds
- Reduced cycle time improves productivity
- Improved strength and visual quality of the welded joint
As a result, infrared welding is rapidly becoming the gold standard for automated pleated filter cartridge manufacturing.

Their newly released
Model NO SIIC-M025 is a state-of-the-art infrared welding system purpose-built for modern production lines. It is the most advanced system in INDRO’s portfolio and is designed to meet the strict requirements of high-end filter applications.
4. Model NO SIIC-M025: Key Features and Advantages
The
SIIC-M025 represents the cutting edge of
filter cartridge end cap welding equipment. It integrates intelligent control systems, high-efficiency IR heaters, and a modular mechanical design to deliver outstanding welding results.
a. Non-Contact Infrared Heating
The system uses powerful, fast-response IR emitters to uniformly heat the welding surfaces of the filter cap and cartridge body. This method ensures:
- Cleaner weld areas
- Minimized deformation
- Lower risk of contamination
- Higher bond strength
b. Water-Cooling Integration
Unlike older systems, the SIIC-M025 is equipped with an advanced
water-cooling mechanism that rapidly cools the welded parts. This reduces cycle time and allows for continuous, high-speed production without thermal stress or deformation.
c. Intelligent Temperature and Time Control
The system is managed via an integrated
PLC (Programmable Logic Controller), allowing users to precisely set and monitor:
- Preheat temperature
- Heating time
- Cooling cycle
- Pressing force and duration
This level of control eliminates variability and enhances repeatability across batches.
d. Automated Clamping and Centering System
The machine uses servo-driven arms to automatically position and clamp the pleated filter and end caps, ensuring perfect axial alignment and consistent weld geometry.
e. User-Friendly Interface
The machine comes with a touchscreen
HMI (Human-Machine Interface) that supports recipe management, parameter storage, and multilingual operation. Operators can quickly switch between product sizes and welding settings with minimal downtime.
f. Compatibility and Flexibility
Model NO SIIC-M025 is compatible with a wide range of filter sizes (typically 10” to 40”), materials (PP, ABS, nylon, fiberglass, PTFE, PVDF, PES), and end cap types (DOE, SOE, flat, fin, 222, 226, etc.). This makes it an ideal choice for both high-volume production and flexible small-batch customization.
5. Application Scenarios
The SIIC-M025 infrared welding system is especially well-suited for manufacturers producing:
- High-purity water filters for semiconductors
- Sterile-grade filters for pharmaceuticals
- Food-grade filters requiring cleanroom-level assembly
