What is a coating machine

Firstly, let's understand what is a coating machine?

Coating machine is mainly used for film, paper and other surface coating process production, this machine is the rolls of substrates coated with a layer of specific functions of the glue, paint or ink, etc., and drying and winding.

The use of special multi-functional coating head, can achieve a variety of forms of surface coating production, the winding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanism, PLC programme tension closed-loop automatic control.

A general coating machine, including a first pre-treatment device, a coating roller, a first coating die head and an after-treatment device, the first pre-treatment device, the coating roller and the after-treatment device are sequentially set up along the transmission direction of the substrate; the first pre-treatment device is set up on one side of the substrate, the first pre-treatment device is used to paste adhesive paper or coat glue on the surface of the substrate, and the adhesive paper or the coated glue partially covers the surface of the substrate; the first coating die head and the coating roller are disposed on both sides of the substrate respectively, the first coating die head and the coating roller being disposed opposite to each other; the post-processing device is disposed on one side of the substrate, and the post-processing device, for treating the adhesive paper or glue on the surface of the substrate, so as to cause the adhesive paper or glue on the substrate to come off from the substrate. In addition, a coating method is provided. With the above coating machine and coating method, the shape of the adhesive paper and the shape of the coating of the glue can be set according to actual needs, the operation of pasting the adhesive paper or coating the glue on the surface of the substrate is simple and easy to carry out, and it can satisfy the coating of the substrate surface with a complex shaped pattern.
Types of coating machine:

First, the most common BOPP PET film coating machine


Second, lithium battery coating machine

Comma scraper coating, micro-intaglio coating, sewing extrusion coating, lip coating, reversed anastomosis coating, coating dozens of ways to apply to different types of products, commonly used about ten kinds of ways, high-precision coating methods are micro-intaglio coating, slit extrusion coating and lip coating and so on.

Third, paper self-adhesive coating machine
Self-adhesive coating machine: the equipment is widely used in: label paper, double-sided tape, kraft tape, adhesive tape, glass fibre adhesive tape, striped paper tape, and its related coating process production.
PVC electrical insulating tape coating machine
Suitable for PVC electrical insulation tape and other soft substrate coating

V: Optical film precision electronic coating machine
Optical film precision electronic coating machine, for a variety of colours thickness PET film, release film, fluorine release film, a variety of release force coating and release, micro-concave coating double anti-static 1-3 grams of release film, PET coated with silicon. Coated antistatic liquid!
VI. Release paper coating machine



1. High temperature resistance, moisture-proof, oil-proof, generally used in food industry packaging.

2. General release paper: moisture-proof, oil-proof, play a role in isolation of the product, applicable industries: electronics, automotive foam, printing, etc., it is used in most of the scope of use and has a viscous in the together, especially the tape, so the general need to use the tape of the product will be used in the release paper.

3.PVC wallpaper, PVC leather coated foam process to undertake the role.


Seven, multi-function coating machine

Surface coating external, coating glue, varnish, coating release agent, solvent-free, hot melt adhesive, suitable for film, paper, fabric, leather, synthetic fibres, new materials, aluminium foil, copper foil surface coating treatment.
Nanjing Suminoe Precision Machinery Co., Ltd. is committed to creating high-precision, high-efficiency, high-capacity, low-cost film sheet equipment.
