Introduction to the Wuxi Xielì Automatic Mixing System for Friction Materials

The Wuxi Xielì Automatic Ingredient‑Mixing System for Friction Materials is an automated weighing and batching solution developed by Wuxi Xielì Automation Equipment Co., Ltd. for the production of friction materials. It is primarily designed for manufacturing automotive brake pads and clutch discs. For more information, please visit our official website. www.wxxieli.com This system leverages mobile automated batching and computer‑based monitoring to address the challenges of precise multi‑material weighing and error prevention, offering high accuracy, superior environmental performance, and robust reliability.

I. System Model and Configuration

1. Multi-specification hopper system : A mobile automated batching system offering multiple silo configurations, including 28  Hopper, 36  Hopper, 42  Hopper and 48  Hopper and other models can accommodate production needs of varying scales.

Weighing vehicle configuration: Typical configuration 2  The Tai‑San three‑hopper or single‑hopper weighing vehicle supports simultaneous material weighing, enhancing efficiency and automatically verifying weighing errors.

Footprint dimensions: With 36  Taking the silo system as an example, the equipment occupies an area approximately length 25  Rice, width 6  Rice, tall 9  Rice.

2. Manual Error-Proofing Ingredient Dispensing System ：

For small-batch or special materials, we offer a manual weighing and automated error-proofing batching system, equipped with a hand‑pushed weighing cart and a computer‑based monitoring system.

Operating mode: Manual material retrieval and barcode‑based warehouse access are employed, with wireless communication enabling signal exchange between the industrial control computer and the lower‑level controller, thereby preventing human errors in ingredient batching.

3.  Automatic Ingredient Weighing System:

Suitable for small-batch prototyping in laboratories or for original‑part workshops across multiple industries, enabling… 20-48 Integrated process control for the automated weighing of raw materials.

II. Key Technical Features

1. High Precision and Error-Proof Management: The system automatically verifies weighing errors using a three-bin scale configuration, preventing ingredient‑mixing deviations, and is equipped with a barcode‑based error‑proofing management system for hopper feeding.

Barcode Control: Scanning the material barcode label opens the corresponding storage bin; only one indicator light illuminates at a time, and an audible and visual alarm sounds before the bin door closes, ensuring accurate material loading.

Data Traceability: The computer records batching information—including operator and weight—ensuring traceability of errors and supporting query and report printing.

2. Environmental Protection and Adaptability: Given the wide variety of raw materials used in friction materials (typically… 30-60 Due to the nature of the material and the high dust generation, the system employs a fully enclosed dust‑proof design and a high‑performance dust‑removal system.

Material Compatibility: Suitable for screw feeding of powdered materials and belt feeding of flaky or fibrous materials, it accommodates raw materials with widely varying particle sizes, ranging from nano‑scale graphite to centimeter‑scale steel fibers.

3. Intelligent Control: It consists of an industrial control computer system, barcode management software, and an electrically controlled silo‑cover system, and is equipped with a large display screen that shows batching management information and the silo’s weight.

III. Application Scenarios and System Architecture

1. Main application areas: It is widely applicable to automated weighing, batching, and mixing processes in manufacturers of friction materials such as automotive brake pads, automotive clutch discs, and railway brake shoes.

Industry Recognition: This system has been widely adopted in the friction materials industry and has received numerous honors, including the China Light Industry Science and Technology Excellence Award and the Third Prize of the China Machinery Industry Science and Technology Award.

2. Hardware components: The complete system comprises a three‑story steel platform, dozens of material storage bins, a full set of feeding equipment, and a high‑performance dust‑collection system.

Auxiliary equipment: It includes an automatic weighing and portioning machine for friction material mixtures, typically positioned beneath the mixer to enable automated weighing and dispensing of the mixture.
