Metering Rod (Mayer Rod) Coating Machine

Introduction

In Mayer rod coating process, an overabundance of the coating is saved onto the substrate as it disregards the shower roller. The wire-wound metering rod, at times known as a Meyer Rod, permits the coveted amount of the coating to stay on the substrate. The amount is controlled by the measurement of the wire utilized on the rod. This process is astoundingly tolerant of non-accuracy building of alternate segments of the coating machine.

It utilizes the utilization of a container nourished kiss applicator roll which exchanges an abundance measure of coating to the web took after by either a smooth metering rod or wire wound mayer bar (wire wound rod) to smooth or meter the coating. Coating weight varieties are made by either fluctuating the web strain over the smooth rod or by utilizing wire wound rods with shifting wire measurements, a bigger wire measurement giving a higher coating weight. Cover weights can likewise be controlled by shifting the point of wrap on the applicator roll and metering rod.

These sorts of coater rod coater are dominatingly utilized as a precoater or back wet coater for sheets on the grounds that the way of its operation permits it to give the board creator an amazingly smooth base on which to apply the optional or top coating.

Why Choose Kerone Metering Rod (Mayer Rod) Coating Machine

We at KERONE are having 48+ years experience in designing and manufacturing various types of specialized coating and impregnation plants for various industrial processing needs of our clients. We are having immense experience in designing and manufacturing of Metering Rod coating machine that can best fit for the size and various processing requirements of the client’s business. The Metering Rod coating machines manufactured by KERONE are made with high quality internal and external material by taking discreet efforts for the perfect coat and uniform heat distribution.
With decades of experience in precision coating technologies, Kerone designs metering rod coaters that deliver stable coating thickness, uniform surface profiles, and quick rod change capabilities. Each system supports multiple rod diameters, coating chemistries, and substrate types, allowing manufacturers to switch between coating weights with minimal downtime. Kerone machines integrate advanced tension control, smooth web handling, and optional inline drying systems to ensure flawless coating deposition even at industrial production speeds.
A standout amongst the most prominent coating systems. The Mayer rod is a stainless steel rod that is wound hard with stainless steel wire of shifting breadth. The rod is utilized to doctor of the overabundance coating solution and control the coating weigh. The wet thickness in the wake of doctoring is controlled by the distance across of the wire used to wind the roll and is pretty nearly 0.1 times the wire measurement. Rods are accessible in a wide mixture of wire sizes to give a scope of coating weights. The table underneath gives the wire sizes that are accessible and the wet thickness that can be attained to. The dry thickness is dictated by the solids centralization of the coating solutions.

Types and Features of Metering Rod (Mayer Rod) Coating Machine

Kerone offers a complete range of metering rod coating systems suitable for both laboratory and large-scale industrial applications. Wire-wound Mayer rods, available in various wire sizes, provide highly controlled wet film thickness for adhesives, primers, and low-viscosity coatings. Smooth steel rods are offered for applications requiring minimal texture or extremely thin films. Interchangeable rod cassette systems enable rapid changeovers between coating weights, improving operational efficiency. Single-station rod coaters are ideal for simple coating processes, while dual-coating rod systems allow sequential or multilayer coatings in a single pass. For continuous production lines, Kerone supplies rod coaters with integrated hot air, IR, or multi-zone drying chambers to ensure complete curing and smooth film formation. All systems are designed for stability at high speeds and compatibility with a wide variety of coating formulations.
