Plastic mould material,Nylon product mould supplier ,water-pump mould supplier,water meter mould supplier,China raw material supplier.
Usually nylon material easily absorb water, containing a hydrophilic group (amido group),
nylon 6 (PA6), nylon 66 (PA66), and is a crystalline thermoplastic material; crystalline polymer,
in the injection molding processing, it is rapid cooling so that the material cannot be natural crystalline shape,

so that the material will have a strong inner stress inside. Nylon material without "tempering" process,
after setting macromolecules, its interior will still tend to the natural orientation, the movement of crystallization,
which causes material stress is further exacerbated. Therefore, the nylon pieces have not been boiled step its
brittle when subjected to an external force, it is easy to collapse out or breakage.

The nylon pieces boiled optimum temperature and time:
90-100 ℃ ,2-3 hours.
Below 90 degrees, the effect is not good, more than three hours, there will be no better results. Cost-effective in terms of the above conditions.
