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. Do not cut the plastic mold with weight, and compare the thickness of the product. Through the recovery of the comminuting material, after the pulverization, and always with the cement slurry powder, under the same steel mould injection molding, the products made are 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 be too to compare prices and buy 2 40 yuan mould is worse than a 50 yuan mould durable, make cement size stability, and nothing more than inflation, 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. The plastic molds made by the pulverized material, with many black spots on the surface, the turbidity is not bright, and the force deformation is large. 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。 4. The appearance of mould products should not have many flying side burrs, with the marks of knives and pins. The influence of the appearance of the product is the reason of the injection molding, the steel mould is not good, the quality of plastic mould is not much better. 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. 5. Customers buy special cement prefabricated plastic mold of the best to specializing in the production of plastic mold parts procurement, mostly in jiaxing, zhejiang, hebei baoding, compared with other regions agents.
