Its technology has been evaluated by the Ministry of Education as being at the domestic leading level and has won two national-level industry science and technology awards. To date, it has accumulated… 70 The remaining equipment has been installed and put into production, with applications in the friction materials industry exceeding… 40 The solution has been rigorously field‑tested and enjoys an outstanding reputation, with benchmark customers including leading friction‑material companies such as Shandong Jin Qilin and Chongqing Hongyu.

Product innovation adopts a rail-based approach. RGV Mobile weighing architecture, enabling " Multi-warehouse vehicle, shared weighing " , completely distinct from the traditional " One warehouse, one scale " A fixed‑type batching solution, specifically designed for powder‑manufacturing applications that involve multiple raw materials, diverse formulations, significant dust generation, constrained plant floor space, and stringent requirements for precision and quality traceability.

II. Operating Principle: Mobile weighing with fully automatic closed-loop operation.

The rail‑guided weighing trolley autonomously traverses a pre‑set track beneath the hoppers, sequentially reaching the designated bins and completing material intake and dynamic weighing via a sealed docking mechanism. Once the entire recipe has been weighed, it automatically transfers the materials to the specified mixer for feeding. The entire process is fully automated by a proprietary industrial control system that records data in real time, with the capability to configure single or multiple trolleys to operate in coordination and serve one or more mixers, thereby maximizing equipment utilization.

III. Two flagship models, precisely tailored to meet diverse needs

1. I Type (Economy) —— Mature and stable, a high‑value‑for‑money choice.

Production capacity 2 ~ 3 ton / Hourly, mature and stable model; suitable for standard friction materials and refractory materials, with moderate budgets for mass production and technological upgrades. It can support long-term stable operation across dozens of storage bins, with weighing accuracy reaching ±0.5% 。

2. II Model (High-End Dual-Stage Closed-Loop Version) —— Precise traceability, OEM‑level standards

Production capacity ≥3 ton / Hours, automotive-oriented OE Supporting high‑precision manufacturing enterprises; equipped with a two‑stage closed-loop dynamic metering system. + End-to-end traceability and error-proofing, with stable precision. ±0.1% ~ ±0.5% , meeting the OEM’s stringent factory audit requirements and batch‑to‑batch consistency control standards.

IV. Six Core Technological Highlights, Building Differentiated Competitive Advantage

1.  Dynamic high-precision weighing

Our proprietary dynamic drop‑compensation and vibration‑filtering algorithms, combined with a shock‑absorbing mechanical structure, effectively counteract weighing deviations caused by motion‑induced vibrations and powder impacts, ensuring long-term weighing stability.

2.  Sealed, dust-free, and environmentally friendly structure

The vehicle’s material receiving and discharging ports are equipped with telescopic seals. / Double-layer skirt, with optional linked negative-pressure vacuuming; key sensors and locomotion components are designed to… IP65/IP67 Dust‑proof protection, suitable for the production of dust‑generating powders such as graphite and metal powders, fully compliant with environmental protection and safety‑supervision standards.

3.  Multi-Intelligence Error Prevention

Triple safeguards: bin‑identification lockout, recipe interlock, and process validation. If the previous material fails to meet weight specifications, the system automatically prevents the next step, thereby mitigating quality risks caused by human oversight or mis‑allocation at the source.

4.  Flexible and easily scalable

For new raw materials, only an additional storage bin is required; no separate weighing unit needs to be added. The system can store hundreds of formulations and switch between them with a single click, perfectly meeting the demands of flexible production for multiple product varieties and small batch sizes.

5.  Full digital traceability capabilities

Automatically records the formula number, materials, weight, time, and operator information for each batch, and automatically generates a shift report. / day / Monthly report; standard interfaces are reserved for integration with enterprise systems. MES 、 ERP The system replaces manual paper-based record-keeping and seamlessly aligns with quality‑system audits.

6.  Strong material compatibility

It can be equipped with optional modules such as arch-breaking, antistatic, and explosion-proof features, enabling it to handle powder raw materials with widely varying characteristics, including fibers and metal powders.

V. Widely Applicable Industries

● Friction materials: automotive brake pads, clutch friction plates

● Refractory materials, powder metallurgy: Powder blending for automotive components

● Deoxidizer / Reformulation of preservative powders

● Other multi-formula, high-precision powder batching applications

VI. Five Core Advantages Compared with Traditional Fixed-Configuration Batching Lines

1.  Space-saving —— Preferred Options for Old Factory Building Renovation

A single weighing unit can serve dozens to hundreds of hoppers, and the advantages of renovating existing factory buildings are particularly pronounced, typically resulting in cost savings. 50% The above equipment occupies space.

2.  Long-term investing is superior. —— The more silos you have, the more cost-effective it is.

The greater the number of storage bins, the more pronounced the advantages in equipment capital costs and operational maintenance expenses compared to a multi-scale fixed‑type solution.

3.  Easy to operate and maintain —— Few failure points, modular design

It features reduced motion and fewer sensing points, resulting in fewer failure points, while its modular design facilitates maintenance.

4.  Artificial workload reduction —— Highly automated, saving both labor and effort.

The batching process is highly automated, significantly reducing labor input for batching, inspections, and record-keeping.

5.  Strong compliance capabilities —— Electronic traceability ensures smooth regulatory approval.

Complete electronic traceability records enable you to easily meet the quality system requirements of the automotive parts industry and pass customer factory audits.

VII. One-stop supporting services for seamless, worry-free experience throughout the entire process

Wuxi Xielì offers a one-stop, end-to-end service encompassing preliminary site surveys, custom‑solution design, equipment manufacturing, on‑site installation and commissioning, operator training, and long‑term technical operation and maintenance—providing comprehensive support from concept to implementation, so our customers can enjoy peace of mind, confidence, and reassurance.
