路沿石模具材质材料分析
发布人:管理员   发布时间:2020-7-3

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。
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.

Engineering PP (polypropylene) is used as raw material for curbstone mould. The material has good malleability, machinability, hardenability, hardenability and grindability. It also has small oxidation, decarburization sensitivity and quenching deformation cracking tendency. The raw materials used in all plastic molds are first-class new materials, without crushing and returning materials. Therefore, do not use the molds made by crushing return materials on the market. The molds made by crushing return materials have short service life, easy aging and deformation. The surface is uneven, and the cement parts are not easy to demould. Please be careful when 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、 Do not compare the weight, cut the plastic mold can compare the product wall thickness. After crushing, the recycled material still contains cement slurry powder. Under the same steel mold 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 compare the price too much. If you buy two 40 yuan molds, it's not as durable as a 50 Yuan mold. The size of the cement parts made is stable, and 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、 There are many black spots on the surface of the plastic mold made by crushing and returning materials, which is turbid and not bright, and has large deformation after force application.


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、 There should be no flash, burr and trace of knife pin on the appearance of mould products. The influence of product appearance is the reason of steel mold injection. If the steel mold is not opened well, the quality of plastic mold is not much better.

五.客户购买水泥预制件专用的塑料模具****到专业生产塑料模具密集的地区采购

5、 It is best for customers to purchase special plastic moulds for cement prefabricated parts in areas with intensive production of plastic moulds
