成型特性
1.结晶料,吸湿性小,易发生融体破裂,长期与热金属接触易分解.
2.流动性好,但收缩范围及收缩值大,易发生缩孔.凹痕,变形.
3.冷却速度快,浇注系统及冷却系统应缓慢散热,并注意控制成型温度.料温低温高压时容易取向,模具温度低于50度时,塑件不光滑,易产生熔接不良,流痕,90度以上易发生翘曲变形
4.塑料壁厚须均匀,避免缺胶,尖角,以防应力集中.

详细说明：
‘Your father and Thorarin my brother have had talk about a marriage betwixt you and me, Hallgerda. Is it your will, as it is theirs- Tell me all that is in your heart. For, if you like me not, I will straightway ride back again.’
‘The match is to my liking,’ answered Hallgerda, ‘and better suited to my condition than what my father made for me before. And you are to my liking also, if our tempers do not fall out.’
