产品详细信息

用于PMMA塑料光导管的透明PMMA树脂

这种PMMA颜色鲜艳，表面光洁度高。外模经模具热压成型后，即使平整抛光，仍能保持成型的图案，形成独特的艺术效果。它可以用来制作人物、动物形状、商标、装饰品和宣传材料

基于上述质量要求，导光板的主要加工要求如下：

2）需要稳定的设备注入和准确的测量

3）设备的注射量不需要太大，太大容易导致熔体变黄变色。为了防止塑料发黄和出现黑斑和黄斑问题，增塑部件的平滑度很高

4）需要高喷射压力和快速喷射速度。由于PMMA和PC塑料熔体流动性差，特别是在加工薄壁导光板时，需要较大的注射压力和注射速度

5）由于熔体的高粘度，螺杆具有较大的旋转扭矩。同时，在结构设计中要求螺杆具有较强的抗扭性

6）。模具设计必须满足顺利填充和顺利脱模的要求。模具加工精度高，有精确的排气槽

Transparent PMMA Resin For PMMA Plastic Light Guide

Product Details

Transparent PMMA Resin for PMMA Plastic light guide

This type of PMMAhas bright color and high surface finish. After the outer form is hot pressed by the mold, even if it is flattened and polished, it still maintains the molded pattern and forms a unique artistic effect. It can be used to make figures, animal shapes, trademarks, decorations and promotional materials.

Based on the above quality requirements, the main processing requirements of the light guide plate are as follows:

1) The clamping force of the injection molding machine should be sufficient, and the parallelism of the template should be high to ensure that the product does not come out of the flash and the thickness is uniform.

2) Stable injection of equipment and accurate measurement are required.

3) The injection volume of the equipment does not need to be too large, and too large may easily cause the melt to turn yellow and discolor. In order to prevent the yellowing of plastics and the problem of black and yellow spots, the smoothness of plasticized components is high.

4) High injection pressure and fast injection speed are required. Due to the poor fluidity of PMMA and PC plastic melts, especially when processing thin-walled light guide plates, large injection pressure and injection speed are required.

5) Due to the high viscosity of the melt, the screw has a large rotating torque. At the same time, the screw is required to have strong torsion resistance in structural design.

6). The mold design must meet the requirements of smooth filling and smooth demolding. The mold processing accuracy should be high and there is a precise exhaust groove.
