In coatings formulations, additives are a classic example of “small players with a big impact”: there are often more than a dozen or even several dozen types, and whilst the quantity of any single additive typically accounts for only 0.1% to 2% of the total formulation, they directly determine the coating’s dispersibility, levelling properties, storage stability and application performance. Dosing is the first stage through which additives enter the product, and it is also the stage in paint production where human error is most prevalent. Currently, additive dosing in most paint factories still relies on manual labour, which gives rise to five main problems.
Additive packaging often looks similar, and the range of types is vast; identification during dosing relies primarily on the experience and memory of the colour‑matching technician. When switching products, changing shifts or onboarding new staff, instances of picking up the wrong drum or omitting an additive occur frequently; once an error is made, it often results in the entire batch of paint being scrapped. Traditional batching relies on paper work orders, making it inevitable for staff to misread, misidentify or misweigh additives; dosing and weighing are entirely dependent on manual experience, lacking systematic control mechanisms.
A single dosing operation involves multiple stages, including locating materials, weighing, handling, verifying, and recording. With a large variety of small‑volume additives and frequent product changes, the process is complex and time‑consuming. According to actual measurements by equipment manufacturers, manual handling, verification and recording can account for over 30% of the production cycle, which easily becomes a bottleneck in production capacity during peak order seasons.
Dosing records largely rely on paper ledgers and retrospective entries; errors, omissions, and retroactive entries are difficult to eliminate, whilst data is scattered and susceptible to tampering. Should quality issues arise with finished products, it is difficult to trace the complete chain of “raw material batch – dosing records – process parameters” backwards; enterprises often incur additional losses due to an inability to provide evidence.
Dedicated personnel are required for additive dosing, occupying at least one dosing operator; if one person operates the system whilst another supervises, two staff members are required.
Open‑system dosing results in fugitive VOCs emissions, which fail to meet environmental control requirements. With the implementation of environmental protection taxes, dosing methods that do not comply with environmental standards will affect environmental ratings, further increasing the company’s tax burden.
To address the above pain points, the additive automatic dosing dispenser (intelligent additive automatic dosing dispenser system) utilises an integrated solution comprising “error‑proofing via barcode scanning, automatic metering, centralised batching and sealed raw material conveyance” to deliver four key capabilities.
Prior to production, the ERP/MES system transmits production work orders and formulations to the automatic dosing dispenser at the touch of a button. By scanning the work order barcode, staff can immediately identify the types, batches and quantities of additives required for the current batch. During dosing, scanning the barcode or RFID tag on the additive packaging triggers the system to instantly verify the material name, batch number and expiry date—should the wrong material be selected, the electronic scale locks immediately and triggers an audible and visual alarm, preventing progression to the next step; Formulation management is subject to tiered authorisation; on‑site operators are only authorised to execute work orders and have no permission to alter formulation parameters.
The automatic dosing dispenser adopts a high‑precision weighing system and closed‑loop control, and measures according to two levels of “coarse matching+fine matching”, and accurately controls the addition amount of each component, with a precision much higher than that of manual weighing. This is especially critical for additives, which have a “small dosage and great influence” ‑the error of manual weighing is generally 3% ~ 5%, and the deviation of trace additives is enough to cause batch quality fluctuation, while automatic measurement can reduce the error to a very small range, ensuring an accurate formula and a stable batch.
Additives are stored in a centralized way and managed in a unified way. The automatic dosing dispenser picks up the formula according to the work order, continuously mixes ingredients, and automatically switches varieties, which eliminates the need for manual material searching, handling, and repeated checking, greatly shortens the dosing time, obviously reduces the labor intensity of workers, and realizes less humanized production.
The automatic dosing dispenser adopts closed container and pipeline transportation: liquid additives are transported in a closed system, which significantly reduces VOCs volatilization; Powder additives adopt a dust‑free dosing mode to avoid dust escaping. It not only improves the workshop environment and the occupational health of operators, but also meets the increasingly strict environmental protection requirements.
For each dosing, the automatic dosing dispenser system records complete information such as work order number, material batch, actual weighing value, dosing time, operator, etc., and it is not necessary to fill in the form manually, so the data is true and cannot be tampered with. When there is a quality problem, the batch can be checked in a few minutes.
The table below maps the three key pain points against the capabilities of the automatic dosing dispenser, facilitating a quick understanding of the solution’s value.
| Current Challenges | Automatic Dosing Dispenser Capacity | Core Value |
|---|---|---|
| Incorrect or omitted dosing | Work order scanning · ERP error prevention, high‑precision automatic metering | Eliminates incorrect, omitted, excessive or insufficient dosing at source |
| Low dosing efficiency | Centralised batching | Significantly reduced batching time, reduced labour requirements |
| Uncertain data accuracy | Fully automated recording | Accurate data, batch traceability |
| Environmental compliance pressures | Sealed dosing | Reduces VOCs emissions and dust dispersion |
The coatings industry is shifting from a model “reliant on manual experience” to “data‑driven intelligent production”. The additive automatic dosing dispenser not only resolves the three specific issues of incorrect or omitted dosing, inefficiency and inaccurate records, but also transforms the dosing process from “post‑event traceability” to “pre‑event error prevention, in‑process control and end‑to‑end traceability”. For paint manufacturers seeking batch consistency and traceable quality, the additive automatic dosing dispenser represents the first step towards becoming a smart factory—and the step offering the highest return on investment.
