The structure of this type of mould is relatively complex, making it difficult to remove some plastic parts such as caps and closures with detailed threads using standard knock-off methods. After the parts are moulded, they need to be carefully unscrewed from the mould to avoid damaging the threads. With over 15 years of experience in unscrewing moulding, we specialize in Inside Unscrewing Mould, Outside unscrewing mould, and unscrewing mould inside and outside. Therefore, we can design excellent unscrewing moulds to produce various unscrewing products. According to the types of different unscrewing products, we will choose two different demoulding methods: the first one is to use the elastic deformation of the material to forcibly eject the plastic part from the core through the unloading plate when the material allows, which is called Forced demoulding method. The other type is for plastic parts with deeper unscrewing, higher material strength, and higher thread accuracy requirements. We will use the rotational demoulding method. unscrewing injection mold design,auto unscrewing mould,unscrewing injection mould,injection mold unscrewing,Unscrewing Moulds Dongguan Hongke Plastic Precision Mould Co.,Limited , https://www.hongkemold.com
The 7th Golden Spider (Chengdu) Fastener Trade Fair will be held on May 25-26 this year. The Russian fastener industry will be held in a favorable environment. Russia is also actively preparing and issuing fastener standards to improve product quality and Industry competitiveness. In January 2011, Russia adopted a standard for high-strength bolts for bridges; in July of the same year, the Russian Timber Construction Association issued a new standard for connection design of screws and externally threaded screws for wood construction. Including "Connection Requirements and Test Methods for Nails, Screws, and Threaded Screws," and "Design of Timber Connections for Wood Construction Using Threaded Fasteners". In 2012, the RosMetiz Association of Russia issued the standard for the manufacture of nuts STO PM 1-1.003-2011. This standard is for threaded nuts with a diameter less than or equal to M16 and a strength rating of 8. "The current situation of the Russian government is 'to promote the upgrading of Russian fasteners in terms of variety and quality.' In order to expand the variety of Russian fasteners, Russian fastener manufacturers need to do a lot of work, and they are currently enhancing their execution. It's a lot of work."
It is reported that BelZAN, the largest automotive fastener manufacturer in Russia, has been providing fasteners for road construction since 2009 and plans to develop wind power equipment in the future to expand the variety of fasteners and achieve product diversification. The Russian Severstal-Metiz Group also passed the verification of high-strength fasteners for bridge construction. Many fastener factories currently plan to expand their mechanical plant.
Russia is the second largest export market for fasteners in China. The share of China’s fastener imports in the Russian market is also rising. In 2011, China’s exports of fasteners to Russia reached 216,393 tons, a year-on-year increase of 27.3%. The amount reached US$309,521,705, an increase of 47.1% year-on-year. The arrival of the new Putin era is also a good news for the fastener industry. Together with the official approval of Russia for accession to the WTO at the end of last year, tariffs are expected to be lowered and the trading system is more transparent. We think this will help. In China's fastener companies to further tap the Russian market opportunities. Open up the potential market, the most popular fastener professional media - Golden Spider media bravely pioneered, recently, Golden Spider Chengdu show debut in the latest issue of the Russian fastener magazine "Fasteners, Adhesives, Tools &..." (FATA for short) magazine).
