产品详细信息

聚甲醛

工艺特点：
（1）聚甲醛在加工前无需干燥。最好在加工过程中预热（约81°C），这有利于产品的尺寸稳定性
（2）聚甲醛的加工温度很窄（0～216℃），在桶内停留时间长或温度超过221℃时会分解，产生强烈的刺激性甲醛气体
（3）POM材料的保持压力应相对较大（接近注射压力），以减少压降。螺杆转速不宜过高，残余体积应小
（4）聚甲醛制品收缩率大，易收缩变形。POM的比热大，模具温度高（81～101℃）
（5）聚甲醛应在“中压、中速、低料温、高模温”的条件下成型加工，精密产品成型时需控制模温
（6）高机械强度和刚度
（7）最高疲劳强度
（8）良好的耐环境性和耐有机溶剂性
（9）抗反复冲击性强，电气性能好，恢复性好，自润滑性好，耐磨性好，尺寸稳定性好

Polyoxymethylene

Product Details

Polyoxymethylene

Process characteristics:
(1) Polyoxymethylene does not need to be dried before processing. It is better to preheat (about 81°C) during processing, which is good for the dimensional stability of the product.
(2) The processing temperature of Polyoxymethylene is very narrow (0～216℃), it will decompose when it stays in the barrel for a long time or the temperature exceeds 221℃, and produce strong irritating formaldehyde gas.
(3) The holding pressure of the POM material should be relatively large (close to the injection pressure) to reduce the pressure drop. The screw speed should not be too high and the residual volume should be small;
(4) The shrinkage rate of POM products is large, and it is easy to shrink or deform. POM has a large specific heat and high mold temperature (81～101℃).
(5) Polyoxymethylene should be molded and processed under the conditions of “medium pressure, medium speed, low material temperature, and higher mold temperature”, and mold temperature control is required when precision products are molded.
(6) High mechanical strength and rigidity
(7) The highest fatigue strength
(8) Good environmental resistance and organic solvent resistance
(9) Strong resistance to repeated impact, good electrical properties, good recovery, self-lubricity, good wear resistance, and excellent dimensional stability.
