塑料模具所用的原材料
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 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 crushing and recycling, so don't use crushing and
recycling to make moulds on the market. The use of crushing and
recycling to make moulds has short service life, easy aging and
deformation. The surface is uneven, and 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. 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 prices too much. Buy 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,表面有很多黑點,渾濁不光亮,加力變形大。
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.
