Pmma勺子成型特性：

（1）Pmma占有很大一部分，其流动性比PS ABS差，熔体粘度对温度变化更敏感

在此过程中，熔体粘度主要由注射温度变化而来。因此，需要高材料温度和高注射压力的注射成型

其中，注射温度的影响大于注射压力，但注射压力的增加有助于提高产品的收缩率

（2）PMMA为非晶态聚合物，熔点大于160℃，分解温度为270℃，无明显熔点

注射温度范围宽，因此材料温度调节范围宽，可制造性更好。因此，可通过注射温度改善流动性。耐冲击性差，耐磨性差，易划伤，易脆化，所以模具温度应该提高，冷凝过程应该改进，而

（3）PMMA注射温度可以通过熔融空气注射法进行观察和判断。熔体应明亮透明，无气泡，温度应尽可能低，同时满足产品要求

PMMA spoon molding characteristics:

(1) PMMA occupies a large degree, its fluidity is worse than PS ABS, and the melt viscosity is more sensitive to temperature changes.

During the process, the melt viscosity is mainly changed from the injection temperature. Therefore, injection molding with high material temperature and high injection pressure is necessary.

Among them, the influence of injection temperature is greater than injection pressure, but the increase in injection pressure helps to improve the shrinkage rate of the product.

(2) PMMA is an amorphous polymer, the melting temperature is greater than 160C, the decomposition temperature is 270C, and there is no obvious melting point.

The injection temperature range is wide, so the material temperature adjustment range is wide, and the manufacturability is better. Therefore, the fluidity can be improved from the injection temperature

Proceed. Poor impact resistance, poor wear resistance, easy to scratch, easy to brittle, so the mold temperature should be increased, the condensation process should be improved, and the

Take these shortcomings.

(3) PMMA injection temperature can be observed and judged by the melt-to-air injection method. The melt should be bright, transparent,

No bubbles, the temperature should be as low as possible while meeting the requirements of the product.
