Flat-Square Wire Covering line

Mitsuba Manufacturing's flat-square wire coating line is provided with a line system equipped and devised with the purpose of being able to cover micron-order coatings without cutting the resin, mainly by means of our extruders compatible with super engineering plastics such as PPS resin and PEEK resin.
Now that CO2 reduction is required as a measure to prevent global warming, the shift to motor-driven vehicles such as hybrid vehicles and electric vehicles is rapidly accelerating for most of the automobiles.
The flat-square wire used for motor coils is covered with an insulating layer which many companies are overwhelming for the development of electrical resistance, heat resistance, strength and so forth to make products developed. It is an industry where great demand is expected in the future.

Product Features

1.Plastic Extruder

・In order to extrude resin with a coating thickness of 100μm or less with high discharge accuracy, we have a lineup of small diameter extruders with a screw diameter of φ14 mm.

※Please separately contact us for more than 150 mm.

・Mitsuba MFG Co. originally has back ground of manufacturing rubber extruders. Because of this, it is highly evaluated by customers for its excellent durability since we generally use common parts of rubber extruders, gear boxes and thrust bearings,

which have higher viscosity and higher back pressure than resin materials.

・Our standard design, including the head, requires 35MPa (MAX.50MPa) for regular use.

※Please contact us for pressure resistance higher than the standard design as it can be handled separately.

2.Preheater

・You can choose from two types. For insulation of thin wires, induction heating type preheater (our original product) with linear speed tracking function, For sheath wire, heater wire and cables that cannot use induction heating, such as thick conductors with a large bending radius, Electric heating furnaces

① Induction Heating Type preheater

Since the conductor is heated using the induced voltage, it is possible to follow the linear velocity.

② Electric Heating Furnace Type Preheater

Suitable for heater wires and sheath wires with insulators that cannot be used with induction heating. In addition, it can be used for thick wires because it passes through the furnace and heats without bending.
