Based on the technical solutions and market applications of Wuxi Xielì Automation Equipment Co., Ltd. (hereinafter referred to as “Wuxi Xielì”), its friction-material batching system—primarily used in the production of automotive brake pads, clutch discs, high-speed rail brake shoes, and other similar products—demonstrates strong industry-specific focus.

This system is not a general-purpose chemical batching unit; rather, it is specifically designed to address the four major pain points in the friction materials industry: a wide variety of raw materials, significant dust generation, complex formulations, and stringent precision requirements.

The following are the core features of the Wuxi Xielì Friction Materials Mixing System:

1.  Core Architecture: Mobile Automated Batching (“One Vehicle, Multiple Silos”)

This is Wuxi Xielì’s most distinctive technical feature and its key differentiator from traditional fixed batching systems.

Dynamic weighing cart: The system employs a wireless-communication-controlled, mobile automated weighing cart. This cart autonomously traverses beneath dozens of hoppers, precisely positions itself, collects material, performs weighing, and then moves to the top of the mixer to discharge the material.

Extremely high space utilization: Traditional fixed systems require dedicated space beneath each hopper for scale installation, resulting in a substantial footprint. Wuxi Xielì’s solution enables dozens, or even hundreds, of hoppers to share a single weighing system (a mobile cart), significantly reducing the required plant floor space—making it particularly well-suited for applications where the number of raw material types can reach 30-50 The friction materials industry.

Flexible multi-device service: A single batching vehicle can serve multiple mixers, with the system automatically planning optimal routes to enable a “one vehicle, multiple machines” cyclical operation, thereby reducing equipment investment costs.

2.  Ultimate dust-proof and sealed design

Friction-material production involves substantial quantities of graphite, carbon fiber, and metal powders, making dust control critical for both environmental protection and workplace safety. Wuxi Xielì’s systems have invested significant effort in dust suppression:

Fully enclosed interface: Dedicated dust-control interfaces—such as telescopic chutes and inflatable seals—have been designed at both the docking point between the batching cart and the material bin and the discharge point between the cart and the mixer.

Negative-pressure dust collection interlock: During material receiving and discharging, the system automatically coordinates with a negative-pressure dust-collection unit to prevent dust from escaping, thereby effectively addressing the persistent problem of pervasive dust in the workshop, protecting workers’ health, and reducing the risk of dust explosions.

3.  High-precision “error-proofing” and “confidentiality” mechanisms

In view of the high cost and complexity of friction-material formulations, the system features highly targeted software and control logic:

The formula is strictly confidential: All ingredient-handling operations are controlled by software, ensuring that workers have no access to specific formulation parameters and thereby preventing human-induced leaks.

Barcode Error-Proofing System: Wuxi Xielì has specially developed a barcode-based error-proofing system for ingredient batching. During manual material feeding or raw-material receiving and storage, the system enforces verification by scanning barcodes; if the wrong material is selected or the wrong bin is used, the system locks the process to prevent progression to the next step, thereby eliminating at the source the risk of entire batches being scrapped due to incorrect material input.

Precise control of trace components: For additives that constitute a very small proportion of the formulation yet critically determine performance—such as friction-modifying agents—the system employs high-precision sensors and variable-frequency speed-controlled feeding (screw). / Vibration / (A belt feeder is optional) to ensure the accuracy of trace dosing.

4.  Feeding Technology Adapted to Complex Material Characteristics

Friction material raw materials come in various forms, including fluffy fibers, hygroscopic mineral powders, and high-density iron powder. The Wuxi Xielì system boasts exceptional adaptability:

Diversified feeding device: Based on material characteristics, flexibly configure various feeding equipment, such as screw feeders, belt feeders, and electromagnetic vibratory feeders.

Arch-breaking flow-assisting design: The hopper is equipped with arch-breaking and flow-assisting devices to prevent bridging and blockage of fibrous materials or adhesion of sticky materials to the hopper walls, thereby ensuring smooth discharge.

5.  Mature industry applications and data traceability

Industry Benchmark Case: This system has already been implemented at several well-known friction-materials companies. For example, Shandong Jin Qilin Co., Ltd. currently has 4 A batching production line has been equipped with Wuxi Xielì’s system, and Jiangsu Fangyi Friction Materials Co., Ltd. has procured Wuxi Xielì’s friction-material batching system and related equipment for its ongoing construction project, demonstrating the company’s recognized leadership in the industry.

End-to-end data recording: The system automatically generates ingredient records for each batch (including time, weight, operator, etc.), supporting data traceability and meeting the stringent supply-chain quality-management requirements of automotive OEMs (e.g., IATF 16949 system).

Summary: The Core Competitiveness of the Wuxi Xielì System
