路沿石模具材質材料分析
發布人:管理員   發布時間: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。
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.

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 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. 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 is turbid and not bright, and has large deformation after force application.


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、 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.客戶購買水泥預制件專用的塑料模具****到專業生產塑料模具密集的地區采購

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