Problem:Poor Finish
When molding Renprene TPVs and our other TPE products,pressures in the
mold work to increase the contact between the shot material and the mold surface.Generally,high injection pressures maintain part properties,improve part appear- ance and reduce molding cycle times.When the melt flow pressures do not allow for the material to pack out evenly against the mold cavity,poor surface finish
can result.
Mold Fill Is Too Slow
The majority of our TPVs are shear dependent.They require fast mold filling via high injection speeds and pressure to increase shear through the system,which reduces their viscosity.If increasing injection pressure and injection speed does not rem-
edy a poor finish,increasing the melt temperature and mold temperature will also improve surface appearance when molding our materials.
Mold Function Is Incorrect
First make sure that venting and gate size are not reducing the melt flow speed.Vents that are too small can lead to trapped air in the mold cavity,which can slow melt flow into the cavity.We do not recommend using mold releases or lubricants.Over time,the lubricants may actually cause the parts to stick in the mold due to build up and vent clogging.Be sure that the mold surface is clean.Avoid thick ribs and bosses that will create sink marks on the opposite side of the part.
Problem:Poor Surface Detail
The leading causes of surface detail problems on parts molded from Santoprene TPVs are improper filling and packing conditions.Pressures in the mold work to increase the contact between the shot material and the mold surface.Generally,high injection pressures maintain part properties,improve part appearance,and reduce molding cycle times.A reduction of pressure in the mold cavity can be caused by the gate freezing off prematurely,poor mold design,or low pack/
hold pressures.Verify that the set up conditions are correct using the Start Up
Procedures.
Mold Filling Improperly
If material is not filling surface details on the part,there may not be enough pres- sure or material to fill the part.First check that the shot size is correct.If the shot size is correct,try increasing the injection speed and back pressure.This will help ensure there is enough pressure in the mold to encourage contact between the melt flow and the mold surface.
Packing Conditions Are Improper
Under-packing of the mold cavity can lead to excessive shrinkage,shrink voids in thicker wall sections,sinks in large surface areas,and poor part appearance.Traditionally,mold fill time takes between 0.5 and 2 seconds,depending on
part volume,runner-gate style and size,cavity locations,and injection pressure.Increasing the second stage pressure and time will also help to maintain pressures in the mold necessary for good surface finish.
Polymer Cooling Rate Is Too High
Increasing mold temperatures will help by reducing the cooling rate of the melt and encouraging filling of surface details.

模具填充速度太慢
我们大多数的TPVs剪切依赖。他们需要快速模具灌装通过较高的注射速度和压力增加通过该系统，从而降低其粘度剪切。如果不增加注射压力和注射速度REM
伊迪一个贫困的完成，提高熔体温度和模具温度也将改善表面外观时，我们的成型材料。
模具的功能是不正确
首先要确定，排气门的大小是不降低熔体流动速度。通风口太小，可以在模具型腔，它可以进入型腔熔体流动缓慢，导致空气被困。我们不建议使用脱模剂或润滑剂。随着时间的推移，润滑油，可能会引起部分粘在模具由于建立和排气孔堵塞。确保模具的表面是干净的。避免粗粗的肋骨和老板对面的一部分，将创造凹痕。
问题：可怜的表面细节
领先的Santoprene TPV的成型零件表面的细节问题的原因是不当的灌装和包装条件。在模具的压力，以增加拍摄的材料和模具表面之间的接触。一般来说，高的注射压力保持部件的属性，改善外观部分，并缩短成型周期时间。在模腔内的压力减少可能造成的过早关闭冻结的门，模具设计不佳，或低包/

程序。
模具充填不当
如果材料不填写的部分表面的细节，有可能没有足够的压力肯定或材料，以填补部分。首先检查拍摄的大小是正确的。如果拍摄的大小是正确的，尽量提高注射速度和背压。这将有助于确保在模具有足够的压力，鼓励熔体流动和模具表面之间的接触。
包装条件不当
在包装模腔可导致过度收缩，收缩在较厚的壁部的空隙，表面积大水槽，和部分外观差。传统上，模具填充时间0.5秒和2秒之间，这取决于
部分的音量，亚军门的样式和大小，腔的位置，和注射压力。增加第二阶段的压力和时间，也将有助于保持必要的压力，在模具表面光洁度好。
聚合物冷却率过高
增加模具温度将有助于通过降低熔体的表面细节，并鼓励填补冷却速度。
