注塑制品的颜色故障你碰见过几种?

现在注塑模具的应用可以说是十分的广泛,注塑模具厂家也如雨后春笋一般蓬勃发展起来,下面山东模具制造厂家给大家总结一下注塑模具制造常见的颜色故障,不知道大家机都见过吗?
Now the application of injection moulds can be said to be very extensive, injection moulds manufacturers have sprung up like mushrooms. Now Shandong mould manufacturers summarize the common color faults in injection moulds manufacturing. Do you know that you have seen them before?
(1)着色剂扩散不良,这种情况往往使浇口附近出现花纹。
(1) The poor diffusion of colouring agents often results in patterns near the gate.
(2)制件的造型和浇口形式,位置对塑料充填情况有影响,使制件的某些局部产生色差,必要时要进行修改。
(2) The shape and gate form of the workpiece and the position of the gate have an effect on the filling condition of the plastics, resulting in color difference in some parts of the workpiece, which should be modified when necessary.
(3)塑料或着色剂热稳定性差,要稳定制件的色调,一定要严格固定生产条件,特别是料温、料量和生产周期。
(3) Plastics or colorants have poor thermal stability. In order to stabilize the tone of the parts, production conditions must be strictly fixed, especially material temperature, material quantity and production cycle.
(4)对结晶型塑料,尽量使制件各部分的冷却速度一致,对于壁厚差异大的制件,可用着色剂来掩蔽色差,对于壁厚较均匀的制件要固定好料温和模温。
(4) For crystalline plastics, the cooling rate of parts should be the same as possible. For parts with large wall thickness difference, the color difference can be masked by colorants. For parts with uniform wall thickness, the material temperature and mould temperature should be fixed.
注塑制品颜色及光泽缺陷的原因分析
Cause Analysis of Color and Gloss Defects of Injection Molded Products
正常情况下,注塑制件表面具有的光泽主要由塑料的类型、着色剂及模面的光洁度所决定。但经常也会因为一些其他的原因造成制品的表面颜色及光泽缺陷、表面暗色等缺陷。造成这种原因及解决方法分析如下:
Normally, the gloss of the surface of injection moulded parts is mainly determined by the type of plastics, the colouring agent and the smoothness of the die surface. But there are also some other reasons that often cause surface color and gloss defects, surface darkness and other defects. The causes and solutions are as follows:
山东模具制造厂家的产品
(1)防止冷料进入制件,必要时改用自锁式弹簧或降低喷嘴温度。
(1) Prevent the cold material from entering the parts, and change to self-locking spring or lower the nozzle temperature if necessary.
(2)料温与模温偏低,必要时可用浇口局部加热办法。
(2) Material temperature and model temperature are on the low side. If necessary, local heating of gate can be used.
(3)模具的浇注系统有缺陷,应增大冷料井,增大流道、抛光主流道、分流道和浇口。
(3) The gating system of the mould is defective, so the cooling well should be enlarged, and the runner, polishing main runner, diversion runner and gate should be enlarged.
(4)模具光洁度差,型腔表面有锈迹等,模具排气不良。
(4) The mold has poor finish, rust marks on the surface of the cavity, and bad exhaust of the mold.
(5)加工压力过低、速度过慢、注射时间不足、背压不足,造成密实性差而使表面暗色。
(5) Processing pressure is too low, speed is too slow, injection time is insufficient, back pressure is insufficient, resulting in poor compactness and dark surface.
(6)使用的再生料过多,塑料或着色剂质量差,混有水汽或其它杂质,使用的润滑剂质量差。
(6) There are too many reclaimed materials, poor quality of plastics or colorants, mixed with water vapor or other impurities, and poor quality of lubricants used.
(7)塑料要充分塑化,但要防止料的降解,受热要稳定,冷却要充分,特别是厚壁的。
(7) Plastics should be fully plasticized, but the degradation of materials should be prevented, the heating should be stable, and the cooling should be adequate, especially for thick-walled materials.
(8)锁模力要足够。
(8) The clamping force should be sufficient.
