The power supply plastic shell has been quite active in our life. Take our common mobile phone charger shell as an example, its main material is made of plastic. A very common feature is that it plays an insulating role. For example, our notebook power supply plastic shell or electric ve…… MORE
At present, the proportion of plastic mold in the whole mold industry is about 30%, and the proportion in mold import and export is as high as 50-70%. In recent years, plastic molds have developed rapidly in China, and plastic products are more and more widely used, providing a broad mar…… MORE
What are the structural design ideas of plastic shell mold? Nowadays, with the continuous improvement of people's aesthetic concept, multi-color plastic shell mold has become a very popular plastic shell mold product. What are the processes of two-color injection molding? 1、 Process anal…… MORE
The mold processing of precision injection molded parts involves many processing procedures, and the quality of each process affects the final mold processing quality of precision injection molded parts. Therefore, we need to pay attention to all aspects in the mold processing of precisi…… MORE
In the process of injection molding, due to the uneven cooling and shrinkage of plastic in the mold cavity and the unreasonable structural design of injection molded parts, it is easy to cause various defects of products: shrinkage, weld marks, pores, deformation, galling, top injury, fl…… MORE
The accuracy of plastic injection mold processing determines the accuracy of plastic parts, so it is very important to control the accuracy of plastic injection mold processing. So how should we control the accuracy in the process of mold processing? 1. Optimize the processing technology…… MORE

In the process of processing medical device shells, the first thing to do is to blanking them. When good blanking is achieved, the next process needs to be carried out. In this process, it needs to bend it. Bending accuracy can reflect the process accuracy of sheet metal processing and t…… MORE
Our friends in the production line know that there are some operating rules for injection molding, and we should know that safety is the primary productivity. Injection molding machine is a complex machine with high temperature, high pressure and fast operation. The operator often neglec…… MORE
在注塑模具加工中模具鑲件的應(yīng)用較為廣泛，不只在前模和后模中可以看到鑲件的應(yīng)用，而且在滑塊和斜頂中也可以應(yīng)用到鑲件。那么鑲件在注塑模具加工中到底有什么樣的作用呢？1、便于注塑模具的加工和維修注塑模具的制造工藝相當(dāng)比較復(fù)雜，在加工過程中，經(jīng)常會遇到一些結(jié)構(gòu)復(fù)雜、形狀特殊的零件，這些零件加工較為困難，并且不容易維修。對于這些……
MORE我們在加工塑膠外殼的時候，經(jīng)常會出現(xiàn)一些問題，其中之一就是開裂。眾所周知，開裂的主要原因是應(yīng)力變形，而應(yīng)力主要可以分為殘余應(yīng)力、外部應(yīng)力和外部環(huán)境引起的應(yīng)力變形。因此，要解決塑膠外殼加工中的開裂問題，注塑模具廠需要從解決應(yīng)力入手。1、殘余應(yīng)力引起的開裂殘余應(yīng)力主要由以下三種情況引起，即過充、脫模推出、金屬鑲嵌。對于注塑……

一．塑膠料的特征1.塑膠料具有質(zhì)輕、比強(qiáng)度高、不銹蝕、絕緣性好、加工性好、加工本錢低、適合大批量消費(fèi)等優(yōu)點(diǎn)，塑膠料在家用電器中的應(yīng)用有著非常重要的作用。2.據(jù)報道，近年美國度電的塑料耗費(fèi)量占其總塑料耗費(fèi)量的4.7%，而日本家電塑料耗費(fèi)量更占到其總塑料耗費(fèi)量的12.3%。我國由于是家電大國，比例更好。3.家用電器中應(yīng)用的……

塑膠外殼披鋒又稱飛邊、溢邊、溢料等，大多發(fā)作在塑膠外殼模具的分合位置上，如：模具的分型面、滑塊的滑配部位、鑲件的縫隙、頂桿的孔隙等處。溢料不及時處理將會進(jìn)一步擴(kuò)展化，從而壓印塑膠模具構(gòu)成部分陷塌，形成永世性損傷。塑膠模具鑲件縫隙和頂桿孔隙的披鋒還會使塑膠外殼品在模上，影響脫模。塑膠外殼披鋒本質(zhì)上是塑膠原料進(jìn)入塑膠模具配……
