The matters needing attention:
|
|||||
MT90 in the factory has been fully dry, moisture content of less than 0. 1%, packaging in the vacuum bag, without drying can directly produce. |
|||||
If the package is damaged material exposure time in the air for too long. MT90 will suck the moisture in the air, moisture content of material is too high, in the injection process, will cause the material overflow in the molten state. The formation of water streak on the surface of the product. At this time, must carry out the drying process: 100 degree vacuum drying 6-10 hours. | |||||
