一、高電壓 新能源汽車普遍工作在B級(jí)電壓范圍，因此要求高壓線束也需要滿足60V-1500V的工作電壓范圍要求，目前普遍的導(dǎo)線電壓要求根據(jù)GB/T 184384.3中對(duì)B級(jí)電壓的規(guī)定為AC30V-1000V，或DC60V-1500V。 二、大電流 新能源汽車高壓線束作為主要的能源傳輸通道，需要承受較大的……

中國信息通信研究院發(fā)布的《5G 經(jīng)濟(jì)社會(huì)影響白皮書》預(yù)計(jì)，到 2030 年 5G 將帶動(dòng)中國直接經(jīng)濟(jì)產(chǎn)出 6.3 萬億元、經(jīng)濟(jì)增加值 2.9 萬億元、就業(yè)機(jī)會(huì) 800 萬個(gè)。 今年兩會(huì)，新基建、拓展 5G 應(yīng)用話題成為關(guān)注熱點(diǎn)，其中，新型基礎(chǔ)設(shè)施建設(shè)（新基建）也包括了 5G 基建。 這意味著，加強(qiáng) 5G 基……

這可能是由以下原因引起的： 一、立式注塑機(jī)的原因 機(jī)器的塑化量或加熱速率不確定，應(yīng)選擇塑化量大、加熱功率大的機(jī)器；螺桿、氣缸或橡膠頭磨損導(dǎo)致返料，實(shí)際填充模量不足；由于熱電偶或加熱環(huán)；等加熱系統(tǒng)故障，料筒實(shí)際溫度過低，注射筒密封磨損，造成漏油或回流，達(dá)不到要求的注射壓力；噴嘴內(nèi)孔過小或噴嘴中心調(diào)整不……

In the plastics processing industry, Shenzhen Taiyou Vertical Injection Molding Machine is a kind of expensive injection molding equipment. The output of vertical injection molding products accounts for more than 30% of the total amount of plastic product

It is very common for vertical injection molding machines to fail because injection molding machines are mechanical. In the long-term operation of any machinery, there will be more or less fault behavior. Because the machine is composed of various parts,

Vertical injection molding machine manufacturers are one of the commonly used equipment in the plastics processing industry and usually require long hours of work. When the vertical injection molding machine is used for a long time, in order to ensure the

1. Obtain: Whether the "mold opening stroke" and "mold support stroke" are enough to take out the finished product depends on the mold and t……
