Coating is a specialized process of material processing where a thin layer of coating material is applied to a substrate surface. This technique enhances the properties and performance of the substrate, contributing to improved functionality, durability, and other desired characteristics. Contract coating refers to outsourcing these services to specialized companies instead of performing in-house processes.

Sun Process Converting is a leading player in custom coating and laminating services. We use advanced coating processes, such as in-line corona treatment and barrier coating, to enhance product quality and cost-effectiveness.

Coating Techniques for Precision Applications

The choice of coating method plays a crucial role in determining the final product’s quality, efficiency, and functionality. Here are several techniques used in different manufacturing projects:

Reverse Roll Coating

Reverse roll coating involves the bi-directional application of material to a substrate. It uses an applicator and a metering roll to ensure precise thickness control, creating a uniform layer. This method is widely known for its adaptability to various substrates and ability to minimize waste.

Gravure Coating

The gravure technique utilizes a roller with engraved cells to transfer coating material onto the substrate. The depth and pattern of the cells control the amount of layer applied, allowing for precise and consistent coverage. This is typically employed in the printing and packaging industries.

Meyer Bar Coating

Meyer bar coating involves using a straight or curved bar to apply a controlled material thickness to the substrate. The gap between the bar and the substrate determines the coating thickness. This is commonly used in various electronic components.

Spray Coating

In spray coating, a fine mist of coating material is applied onto the substrate using specialized equipment. This versatile technique allows for even coverage on complex shapes and surfaces. Hence, it is widely used in the automotive and aerospace industries.

Curtain Coating

Curtain coating is a continuous process where the substrate passes through a falling curtain of coating material. The substrate’s speed and the coating material’s flow rate are carefully controlled to achieve uniform coverage. This technique is commonly employed in paper and film coating.

Industry Best Practices in Contract Coating

At Sun Process Converting, we adhere to the following best practices to guarantee precision, quality, and overall customer satisfaction:

Thorough Material Evaluation

Our process involves a comprehensive assessment of coating materials. This includes analyzing their chemical composition to ensure compatibility with intended substrates. Consideration is also given to each material’s specific functionalities, guaranteeing that the chosen coating meets the application’s unique requirements.

Strict Substrate Compatibility Testing

Rigorous testing assesses the compatibility between coatings and various substrate materials. It also helps identify the most suitable combinations for optimal results. This step ensures that the layer adheres effectively to different substrates without compromising structural integrity.

Quality Assurance Protocols

Our quality control measures include continuous monitoring of coating thickness throughout the process and thorough inspections for defects. By adhering to strict quality standards, we ensure that every coated product meets customer expectations and improves overall business reputation.

Regular Equipment Calibration and Maintenance

Achieving precision in coating applications requires regular equipment calibration and maintenance. This involves fine-tuning parameters such as speed, temperature, and pressure. Doing so keeps the coating machinery in optimal condition and minimizes variations, leading to consistent and accurate application across substrates.
