Acrypet SV001 PMMA量大優惠相關介紹如下(三菱麗陽):
Cells
This may be generated at thick parts of molded product. For clear products, those cells become unmodifiable defect of appearance. One of causes of such cell generation, if those are found at peripheral area not but near middle of thickness, is poor predrying or too high temperature of the cylinder. Cells at middle of thickness are caused from concentration of surface sink to middle of thickness. Some preventive measures listed above are applicable, but the following measures are more effective.
(1) When mold cooling down is done with water after mold releasing, use more warm water or shorten cooling duration.
(2) Set the mold temperature higher.
細胞
這可能是在厚的部分生成模制產品。明確的產品,這些細胞成為無法改變的缺陷的外觀。這樣的細胞生成的原因之一,如果這些發現附近的周邊區域不但是厚度,也是貧窮的預干燥或高溫缸。細胞中間厚度引起的表面濃度水槽中間的厚度。上面列出的一些預防措施是適用的,但是下面的措施更有效。
(1)當模具冷卻用水做脫模后,用溫水或縮短冷卻時間。
(2)設置模具溫度更高。
