Ⅱ. Stopping the molding and changing the material
At the end of molding or when stopping the machine for an extended period, replace the material in the cylinder with high-density polyethylene or other resin. If the TORAYCA® is left in high temperature for a long period, the resin may break down and cause the carbon fibers to solidify, thus making it difficult to continue with the molding work.
Ⅲ. Handling precautions
- When operating a manufacturing process using the TORAYCA® reinforced resin, exercise caution to shut out powder dust from the electrical equipment as much as possible, by maintaining positive pressures in the equipment, for example, so as to prevent the equipment from experiencing short circuiting.
- Dispose of the TORAYCA® reinforced resin correctly as industrial waste instead of burning the resin.
- Read the Material Safety Data Sheet for TORAYCA® reinforced resin before using the resin.
Ⅳ. Mold materials
For injection molding tool using the TORAYCA® reinforced resin, the use of a steel material that has both abrasion resistance and corrosion resistance is recommended. Particularly at the gate and at the flow end, the mold will get damaged easily. Carefully select the steel to be used, and note whether it has been quenched. You are also advised to take appropriate measures, such as adopting a nesting system so that replacement is possible.
