| 路沿石模具材质 The material of the road along the stone 路沿石模具采用工程pp（聚丙烯）原料，材料具有良好的可锻性、切削加工性、淬硬性、淬透性及可磨削性、还具有小的氧化、脱碳敏感性和淬火变形开裂倾向。 The PP (polypropylene) material has good Forgability, machinability, hardenability, hardenability and grindability, and has a small oxidation, decarburization sensitivity and quenching dehiscence tendency. 所有的塑料模具所用的原材料都是一级新料,不加粉碎回料,所以不要市面上用粉碎回料做的模具,使用粉碎回料做的模具使用寿命短,容易老化,变形.表面不平整,水泥件不容易脱模.购买请慎重. All the raw materials used in plastic moulds are grade 1 new material, not comminuted back material, so do not use comminuted mold on the market, using comminuted feed back for short life, easy aging, deformation. The surface is not smooth, the cement is not easy to die. Please buy carefully. 一.不要比重量,切割开塑料模具可以比较一下产品壁厚。通过回收来的粉碎回料,经过粉碎后始终还带有水泥浆粉,在同样的钢模注塑成型下,做出来的产品只有重,不会轻. First, do not cut the plastic mold to compare the thickness of the product. After crushing and recycling, the cement powder is always used after crushing. Under the same steel mould injection molding, the product is heavy and light. 二.不要过于比较价格，买2个40元钱的模具还不如1个50元钱的模具耐用，做出来的水泥件尺寸稳定，又不外膨胀，不存在产品不合格的风险。 Two. Do not compare the price too much, buy 2 40 yuan die is not as good as 1 50 yuan die durable, the cement parts to do the stability, and not to expand, there is no product unqualified risk. 三、粉碎回料做的塑料模具，表面有很多黑点，浑浊不光亮，加力变形大。 Three, crush the plastic mold made of recycled material, there are many black spots on the surface, turbidity is not bright, afterburner deformation is big. 四、模具产品外观不要有很多飞边毛刺，有刀销的痕迹。影响产品外观是钢模注塑的原因，钢模开不好，塑料模具质量也好不到哪里去。 Four, the appearance of mold products do not have many flash burrs, there are traces of knife. The influence of the appearance of the product is the reason for the injection of the steel mould. The mould is not well opened, and the quality of the plastic mold is not good. 五.客户购买水泥预制件专用的塑料模具最好到专业生产塑料模具密集的地区采购,大部分集中在浙江嘉兴,河北保定,其他地区以代理商比较多. Five. Customer purchase of concrete prefabricated plastic moulds is best to be purchased in the area of specialized production of dense plastic moulds. Most of them are concentrated in Jiaxing, Zhejiang, Hebei, Baoding, and other areas with more agents. |
