Acrypet VRL-20 PMMA价格便宜相关介绍如下（三菱丽阳）：

受外来杂质污染
ACRYPET非常常用的模制产品领域根据其光学特性,以便任何外来物质,甚至通过极其分钟的尺度,不能混合。混合的机会可能是建立在许多阶段在成型过程中,可能会花多少时间来消除这些风险。然后,对于减少这些风险,不久以下检查站必须有用得多。
(1)测量多少尘埃漂浮在你的造型植物。
(2)检查是否ACRYPET大约在开箱或少谨慎处理。
(3)检查是否与其他类型的混合树脂预干燥室或与外国物质来自混合干燥板的滑动面及其支架可能会怀疑。
(4)检查斗装载机是否*清洁。
(5)检查是否严重的金属墙之间存在摩擦斗装载机和ACRYPET金属墙是否报废。
(6)检查是否烟雾和灰尘侵入从料斗干燥机的进气口或是否导致外国物质存在于料斗干燥机本身。
(7)检查是否存在任何其他类型的树脂残留在气缸和喷嘴。
(8)检查是否变形筒和螺杆。
(9)检查是否泄漏的石油或粉状金属被发现的推钉模具或其他可移动的零件。

 Surface sink：

This is the sink of product surface that also called as sink mark. 
Preventive measures listed below are actually effective to avoid this.
(1) Set the injection pressure higher.
(2) Extend the high-pressure duration at injection.
(3) Set the cylinder temperature lower.
(4) Set the number of screw rotation at plasticization smaller.
(5) For the thin wall molding, set the mold temperature not to be so high.
(6) For a product having thickness variation, provide a gate additionally at the thick part.
(7) Increase resin feed amount to enable to compensate the shrinkage in the cavities at the injection step required to hold high-pressure. Check-valve is useful for this process.
(8) Uniform the surface temperature of mold.
(9) Enlarge the cross section of sprue, runner and gate, shorten the length of them to make the resin flow easier, and set the cylinder temperature lower.
