Coater has multiple processes such as coating,
drying, and winding processes
The machine to coat chemical and paint on material is called as coating machine. Multiple processes such as coating on material, putting coating liquid on material, drying of multiple layers materials and coating liquid in drying furnace and winding of the sheet at last are called as coater.
FEATUREMakes impossible thing possible by long years results and experience
Success by many tests using test unit
Musashino Kikai coater is used in variety of applications such as processing of paper/polymer film/metal/wood board etc.
We test “the idea of production, which has not been tried yet by actual unit ”using our test unit or a test unit that is delivered to the customer site. Some makers have test units but their support is not good as we do: we have produced results using test unit by many trials and errors based on our long years result and experience. This process helps to reduce risk for customers.
Single company support: Protection of confidential process
We have strong confidence in technology to laminate on coated material: we can complete this process by ourselves and this is one of our good strong points. The customers see this is good benefit because of simplification of communication and protection of confidential data by single company support.
20 types of coating method from ultra thin to ultra thick
The different thickness coating methods for from ultra thick, 1-2 mm to nano-level ultra thin coating using about 20 kinds heads can be used. We have a test machine in a coating process center at Tokyo factory for high level of coating process: we help customers to realize their strong desire and idea as a product and help to develop the competitive only one product.
COATINGCoating method types
The coater is one word but there are many coating types. We use many types of coaters; the followings are main types.

Paint not go from one side to the backside. For small number of lot and many kinds. Easy exchange of gravure roll
Bar coater (mayerbar)
- Coating
- 2〜20g/㎡WET
- Viscosity
- 1〜400cP
- Coating speed
- 〜200m/min
Good for small amount coating in under and top coat. High speed coating possible for smooth and even coating surface.
Three reverse roll coater(Top feed)
- Coating
- 8〜50g/㎡WET
- Viscosity
- 1,000〜50,000cP
- Coating speed
- 10〜180m/min
Wide range of application. Extremely wide range for coating thickness. Most appropriate for high viscosity coating. Many number of parts.
Three reverse roll coater(+fountain die)
- Coating
- 5〜50g/㎡WET
- Viscosity
- 1,000〜50,000cP
- Coating speed
- 〜300m/min
Following issues can be solved and always fresh coating fluid can be used. 1.Due to outside air contact of coating fluid, fluid viscosity changes. 2.Bubble occurs in coating fluid 3.Dry condition of coating fluid
Four reverse roll coater(bottom feed)
- Coating
- 8〜35g/㎡WET
- Viscosity
- 1〜400cP
- Coating speed
- 10〜250m/min
Good for light and low viscosity coating (actual result: 5 μm). Reduce coating fluid loss by low speed operation of pickup roll.
MB (Cylinder blade) reverse coater
- Coating
- 10〜300g/㎡WET
- Viscosity
- 1,000〜50,000cP
- Coating speed
- 〜150m/min
Wide range of coating fluid viscosity; smooth coating surface by much coating fluid
Air doctor coater(air knife)
- Coating
- 1〜50g/㎡WET
- Viscosity
- 1〜1,000cP
- Coating speed
- 1〜300m/min
Only for water coating solvent. Even coating available on uneven sheet by non-contact coating, which does not depend on material thickness.
Forward rotation roll coater(transfer)
- Coating
- 0.5〜5g/㎡WET
- Viscosity
- 100〜4,000cP
- Coating speed
- 10〜500m/min
High density coating fluid use available. Duplex high speed coating at the same time possible. Few streak problem.

MACHINESCoater Model
CLEANClean coater
This is used in the clean room zone to manufacture the products only in the room. The equipment has some necessary functions that emitted dust can be removed and non-volatile oil is used for clean room operation
MULTIMulti coater
Large scale equipment to manufacture adhesive tape, craft tape etc. Line speed is one of important operation parameter.
PVDCPVDC coater
The PVDC coated material is used in many products, e.g. the outer film of medicine tablet. It used to be shifted to vinyl chloride but because of a problem of facing with air we have had many inquiries for PVDC coater, which requires very difficult technology.
HOT MELTHot melt
In general coating target ingredient mixed with solvent is coated but in Hot melt coating melted ingredient is coated and it is set as the temperature goes down. This is old method but this has been collected the attention globally because the solvent used in general coating method can cause environment problem.
