Lotion Coating Machine Buying Guide: How to Choose the Most Suitable Coating Equipment

As the official brand of Subit in Shenzhen, China, we understand the importance of a high-performance emulsion coater for work efficiency and experimental results in laboratory research and industrial production. This article will provide you with professional purchasing advice and show how Subit coating machines can meet your various needs.
The core purchase elements of emulsion coating machine
1. Technical parameters and accuracy
Coating accuracy is a primary consideration when selecting a coating machine. The equipment should ensure uniform coating thickness and meet process requirements, which is directly related to the quality of the final product. In a laboratory setting, the coating thickness range is typically between 1μm and 10mm, and the accuracy should be above ±0.003mm.
In terms of coating speed, according to different production needs, the equipment should provide sufficient adjustment range. Generally speaking, the adjustable speed range of 5-300mm/s is appropriate, which can not only meet the requirements of fine operations, but also adapt to high-efficiency production.
The effective coating size should be selected according to the common experimental or production sample size, the standard model is usually about 300×400mm, or larger sizes can be customized according to needs.
2. Equipment performance and stability
The stability of equipment operation is crucial, and the vibration and speed uniformity of the transmission will affect the uniformity of the film layer. When choosing, attention should be paid to the transmission system of the equipment, and the design of double slide + ball screw + timing belt can significantly improve the smoothness of operation.
The straightness of the bottom plate and the scraper directly affects the uniformity of film formation. Professional manufacturers will use a special process to process the platform to achieve a flatness of less than ±2.5 microns, which can be maintained within the effective width of 300mm and length of 400mm.
3. Material adaptability and versatility
A quality coater should be able to adapt to different types of substrates (such as metal, plastic, paper, etc.) and coatings (such as water-based coatings, oil-based coatings, UV-curable coatings, etc.). For emulsion coating, special consideration should be given to the compatibility of the equipment with water-emulsion adhesives and synthetic resin emulsions.
The combination of multiple coating methods (wire rod/scraper/four-sided wet film preptor) can significantly increase the range of applications of the equipment to meet different coating needs.
4. Ease of operation and automation
Modern coating machines should use touch screen control systems that can accurately control the coating speed, pressure, and coating volume, ensuring accuracy and consistency in coating thickness. Equipment with a high degree of automation can reduce manual intervention, improving production efficiency and consistency.
The outstanding advantages of Subit emulsion coaters:
As a professional coating equipment manufacturer, the emulsion coating machine launched by Shenzhen Subit brand integrates the latest technology and practical design concepts in the industry, and has the following outstanding advantages:
1. Precision process control
Subit coating machines use vacuum adsorption to ensure the flatness and stability of the substrate during the coating process through vacuum adsorption technology, thereby improving coating quality. It is especially suitable for substrates that cannot be paved by themselves, as well as hard materials such as copper foil, aluminum foil, plastic sheet, and glass.
Our equipment is equipped with a weight vertical pressurization system to realize the quantitative adjustment of coating pressure, which fundamentally solves the inconsistency of manual coating. Different personnel can also coat wet film with good repeatability and accurate coating thickness using the same equipment, providing stable specimens for the measurement and research of various coating indicators.
2. Flexible configuration and strong compatibility
Subit coaters support a variety of coating methods, including wire rods and four-sided wet film preparers, catering to different materials and coating requirements. Whether it's a liquid or paste specimen, it can be evenly applied to solid substrates, providing high-quality coatings.
Our equipment coating speed can be adjusted in a wide range (5-150mm/s arbitrarily set), and users can choose the appropriate speed according to their needs. The ball screw transmission is adopted, which has better smooth operation and ensures a stable and reliable coating process.
3. Sturdy construction and durable design
The Subit coating machine adopts 304 stainless steel shell as a whole, which is corrosion-resistant and easy to clean, suitable for laboratory environments. The platform has been treated with a special process, which has good flatness and does not deform when heated within a certain temperature range, which fully ensures the uniformity of coating.
Our equipment is designed and manufactured in accordance with relevant standards such as GB/T9755-2024 "Synthetic Resin Emulsion Wall Coating" and GB/T1727-2021 "General Preparation Method of Paint Films" to ensure the stability of coating effects and coating performance.
4. User-friendly design
Subit coating machine pays attention to user experience, reasonable design, simple and convenient operation, easy maintenance and maintenance. Adopting touch screen control, parameter setting is intuitive and simple, even non-professionals can get started quickly.
Select Suggestions and Summary
When choosing a lotion coating machine, in addition to the performance parameters of the equipment itself, the supplier's technical support capabilities should also be considered. Capable manufacturers can provide sufficient technical support, and through the analysis of the actual needs of customers, they can match the coating machine with better cost performance and more in line with customer needs.
The Subit brand has a professional technical team that can provide customers with perfect pre-sales consultation and after-sales service to ensure that the equipment is always in optimal operating condition. Our equipment has obvious advantages in terms of cost performance, with a price range of 8500-26500 yuan to meet the needs of customers with different budgets.
All in all, a high-quality emulsion coating machine should have high precision, good stability, easy operation, and easy maintenance. Subit emulsion coating machine excels in these aspects, making it an ideal choice for laboratory research and development and quality control. We look forward to providing you with professional and reliable coating solutions to help your scientific research and production work reach a higher level.
