| 材质 Texture of material 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 engineering PP (polypropylene) material is used in the roadside stone mould. The material has good malleability, cutting machinability, hardenability, hardenability and grindability. It also has small oxidation, decarbonization sensitivity and tendency of quenching deformation and cracking. 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 first-class new materials, without crushing and recycling, so don't use crushing and recycling moulds on the market. The moulds made with crushing and recycling have short service life, easy aging and deformation. The surface is uneven, and the cement parts are not easy to demould. Please be careful in purchasing. 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. 1. Don't compare the weight. Cut the plastic mould to compare the wall thickness of the product. The recycled crushing material always contains cement slurry powder after crushing. Under the same steel injection moulding, the product is only heavy, not 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。 2. Don't compare prices too much. Buying two 40 yuan moulds is not as durable as one 50 yuan moulds. The size of the cement parts made is stable and expands. There is no risk of unqualified products. 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。 3. Plastic moulds made of crushing and recycling materials have many black spots on the surface, which are cloudy and not bright, and have large afterburning deformation. |
