About us

Since its founding in 1935, Kawata finds quantitative and optimum conditions through various tests on actual equipment, in addition to the experience and experience that have contributed to every powder and granular industry.
In addition, we will make a proposal that you can rest assured that you can solve planning → testing → verification repeatedly even with materials of your problem.
Since it is also possible to carry out tests with test materials brought in by customers, please contact us.

POWDER TEST AREA

Location: Technical Center

Ceramics, Battery materials, Food additives, Plastics, Pharmaceuticals, Dyes and Pigments, Color toners, Powder metals, Ferrite, Cosmetics, Agricultural chemical raw materials, Zeolite etc. ... You can test any powder.

Conveying

① Blow tank Specification: 40 kg / B
Pressure transport allows for low-speed, high-density, material-friendly Conveying.
② Suction type Conveying device specifications: 40kg/B
Simple powder Conveying is performed using suction Conveying.
③ Powder loader Model: VP / VE-20 Specifications: 20 L
Inexpensive version, ideal for easy Conveying. You can choose from two models: blower specification and ejector specification (compressor).

Mixing

④ Super mixer Model: SMV - ** Specifications: 10, 20, 100 Lr
Uniform high-speed fluid Mixing can be achieved in a short time.
⑤ Super floater Model: SFC-50C Specifications: 10, 20, 50 Lr
Three-dimensional Mixing saves energy, and since it is Mixing while still in the bag, there is no scattering, and it is also easy to clean.
⑥ Piccolo Model: SMP-2 Specifications: 1.8 Lr
This is a compact tabletop type high-speed Mixing.

To measure

⑦ Loss-in continuous feeder>
Popular type specification max 100 kg / hr
Weighing with high precision weighing with subtractive type weighing.
Minute weighing type specification 1.0 to 20 cc / min
Stable supply of ultra trace supply with high precision.
⑧ Autoscale Specification: 40 kg / B
Weighing Conveying Conveying using a weighing machine that also serves as transport.
⑨ Non-bridge feeder Specification: 200Lr
It is possible to supply stable bridging powder easily.

Drying

⑩ Mixer + temperature controller
Moisture and volatile matter can be removed by raising the temperature while Mixing.

Temperature Controlling

⑪ Jacket temperature control
High precision temperature control and program temperature control function are possible. Medium: for water, oil

LARGE DRYER TEST Dryer

Location: Technical Center

We are permanently establishing a large crystal drying test facility that can accommodate various drying tests by bringing in materials of customers.

  • I want to establish the drying condition of newly developed material.
  • I would like to dry materials that are likely to cause thermal fusion and blocking at low temperature & low dew point.
  • It is necessary to prevent oxidation deterioration · yellow etc., I would like to evaluate by N 2 circulation.
  • I would like to stably crystallize the copolymer chips without fusing / deforming them.

We will respond to various requests such as ...
Equipped with measuring equipment such as moisture measuring equipment (Karl Fischer method) and differential thermal analysis equipment, we have built a complete testing system that can perform various drying tests.

MIXER TEST AREA

The super mixer combines an original designed stirring blade and rotates at high speed to create an idealIt creates fluid motion and enables homogeneous Mixing and dispersion of various materials in a short time.
A wide range of effects can be obtained in Mixing, dispersing, grinding, pulverizing, drying, coating, impregnation, surface treatment, etc.
As a test machine, in addition to the conventional 100L high-speed mixer, we have newly prepared a 500L high-speed mixer.It is now possible to perform tests that are closer to the actual line. The following types of test machines are available.

  • For high-speed fluid Mixing
    1.8L, 10L, 20L, 100L, 500L
  • High efficiency dry dispersion
    1.5L, 100L
  • cooling Mixing
    100L, 500L
  • High-speed floating Mixing
    10L 20L 50L

STANDARD EQUIPMENT TEST AREA

Kawata has developed and stocks standard equipment to handle various plastic materials. Dryer, Batch Blender, Conveying Machine, Granulator, etc.We also have an injection molding machine, so we can conduct tests according to customer needs.
