Material Preparation (Mixing,Cutting)
|
～ Chemical Blending ～
 |
Cross-linking chemicals, vulcanization accelerators, and other chemicals are compounded in-house.
The specifications of the chemicals to be used and the amount to be blended are indicated and judged by computer to prevent poka-yoke.
|
|
～ Mixing ～
Kneading is an important process to evenly disperse the compounding chemicals into the raw rubber.
This process produces stable molding quality.
Kneader:1 unit (55L)
|
Two Roll Mill:2 units (16/14 inch)
|
|
Aging (lowering the temperature) is performed to stabilize the properties of the kneaded material.
|
|
～ Material Cutting ～
Cutting Machine:2 units (for Compression)
|
Cutting Machine:2 units (for Injection)
|
|
By optimizing the material volume for compression molding, we can stabilize the molding quality and reduce the amount of scrap.
