路沿石模具采用工程pp(聚丙烯)原料
路沿石模具采用工程pp(聚丙烯)原料,材料具有良好的可鍛性、切削加工性、淬硬性、淬透性及可磨削性、還具有小的氧化、脫碳敏感性和淬火變形開裂傾向。
The molds for curbstone are made of Engineering PP (polypropylene) material, which has good malleability, machinability, hardenability, hardenability and grindability, and also has small oxidation, decarburization sensitivity and quenching deformation cracking tendency.
所有的塑料模具所用的原材料都是一級新料,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壽命短,容易老化,變形.表面不平整,水泥件不容易脫模.購買請慎重.
All the raw materials used in plastic moulds are first-class new materials, without grinding and returning materials, so do not use the moulds made of grinding and returning materials on the market. The moulds made of grinding and returning materials have short service life, are easy to 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,切割開塑料模具可以比較一下產品壁厚。通過回收來的粉碎回料,經過粉碎后始終還帶有水泥漿粉,在同樣的鋼模注塑成型下,做出來的產品只有重,不會輕.
1、 Do not compare the weight, cut the plastic mold to compare the product wall thickness. After crushing, the crushed material still contains cement slurry powder. Under the same injection molding of steel mold, the product is only heavy, not light
二.不要過于比較價格,買2個40元錢的模具還不如1個50元錢的模具耐用,做出來的水泥件尺寸穩定,又不外膨脹,不存在產品不合格的風險。
2、 Don't compare the price too much. Two 40 yuan molds are not as durable as one 50 Yuan mold. The size of the cement parts made is stable, but not inflated, and there is no risk of unqualified products.
三、粉碎回料做的塑料模具,表面有很多黑點,渾濁不光亮,加力變形大。
3、 There are many black spots on the surface of the plastic mold made by crushing and returning materials, which are turbid and not bright, and have large deformation due to force.
四、模具產品外觀不要有很多飛邊毛刺,有刀銷的痕跡。影響產品外觀是鋼模注塑的原因,鋼模開不好,塑料模具質量也好不到哪里去。
4、 The appearance of the mould product should not have many flash burr and the trace of the cutter pin. The influence of product appearance is the reason of steel mold injection. The poor opening of steel mold and the quality of plastic mold are not so good.
五.客戶購買水泥預制件專用的塑料模具最好到專業生產塑料模具密集的地區采購,大部分集中在浙江嘉興,河北保定,其他地區以代理商比較多.
5、 The best way for customers to purchase the special plastic mold for cement prefabrication is to purchase the plastic mold in the area with intensive production of plastic mold, most of which are concentrated in Jiaxing, Zhejiang and Baoding, Hebei. There are many agents in other areas
