盖板模具是以特定的结构形式通过一定方式使材料成型的一种工业产品，同时也是能成批生产出具有一定形状和尺寸要求的沟盖板的一种生产工具，那么哪些因素是和盖板的质量有关呢？,一是盖板模具的材料和质量,二是盖板本身的材料和配比。
The cover plate mold is an industrial product which can make the material form by a certain way with a specific structure. It is also a kind of production tool that can produce groove cover plate with certain shape and size requirements in batch. What factors are related to the quality of the cover plate? One is the material and quality of the cover plate mold, the other is the material and proportion of the cover plate itself.

在盖板模具材料方面,有的客户认为用聚丙烯的原料生产盖板模具价格相对来说便宜,而且还亮度好,还有一些人认为ABS制作出来的比较好,更加耐用。面对ABS和PP这两种材料,其实都有自己的优劣。
In terms of cover mold materials, some customers think that the price of flat mold made of polypropylene is relatively cheap, and the brightness is good, and some people think that ABS is better and more durable. In the face of ABS and PP, both of them have their own advantages and disadvantages.

ABS塑料综合性能较好,冲击强度较高,化学稳定性,电性能良好,熔接性良好,且可表面镀铬,喷漆处理,有高抗冲、高耐热、阻燃、增强、透明等级别。PP塑料密度小,强度刚度,硬度耐热性好,但低温时变脆,不耐模易老化。
ABS plastics have good comprehensive properties, high impact strength, chemical stability, good electrical properties, good fusion, and can be surface chrome plated, spray paint treatment, with high impact, high heat resistance, flame retardant, reinforced, transparent and other grades. PP plastic has low density, strength, rigidity, hardness and good heat resistance, but it becomes brittle at low temperature, not resistant to mold and easy to aging.

而盖板材料和配比方面,是否符合国家标准也是很重要的,设备压力的大小会直接影响到盖板模具,不同压力设备生产的盖板密度有着很大的差别,一般情况下,设备的压力越大生产出的盖板密实度越高、抗折性、抗压强度也就越好。
In terms of cover material and ratio, it is also very important whether it meets the national standard. The size of equipment pressure will directly affect the quality of cover plate. The density of cover plate produced by different pressure equipment has great difference. In general, the greater the pressure of the equipment, the higher the density, bending resistance and compressive strength of the cover plate are.
