  Polypropylene, also known as pp, is a thermoplastic polymer. It can produce various molecular weights by changing the polymerization conditions during production. They are usually used in the manufacture of other items in the form of powders, fibers and granule. Products made of thermoplastics usually use polypropylene granule as input raw materials. The polypropylene granule are simple thermoplastics, made into granular materials with a diameter of about 3 mm. These polypropylene granule are then melted for use by manufacturers of various products. But do you   know abou t it?                                             Polypropylene Granule The Important Features of  Polypropylene Granule Chemical resistance: Diluted alkali and acids are not easy to react with polypropylene, which makes it an ideal choice for containers containing...

  Aluminium Flip Off Seals Molding process plan of aluminum plastic cover: The forming process principle of the easy-open lid finished product. In this process, the tinplate cover ring is sent from the feeding device to the positioning station, and the indexing mechanism turns the tinplate cover ring to the punching and hot pressing station; at the same time, the aluminum-plastic film coil is fed intermittently by the uncoiling mechanism. In the punching and hot pressing station, the punching knife rises to punch the aluminum-plastic film in a punching manner, and then the mechanism continues to rise, directly pressing the punched aluminum-plastic cover sheet onto the tinplate cover ring for two The person performs hot-pressing sealing. The heating device of the station is arranged above the tinplate cover ring. The semi-finished product after hot pressing and sealing is embossed and unloaded in turn by the indexing mechanism to obtain the finished product. Our company also has...

  As an   Aluminium Flip Off Seals Manufacturer , share with you. The aluminum-plastic cover is composed of a tinplate cover ring and an aluminum-plastic composite film cover sheet. The corresponding molding equipment must complete the molding of the aluminum-plastic composite film cover sheet, the hot pressing bonding of the cover sheet and the tinplate cover ring, and the embossing process. In view of the past analysis of the schemes adopted for die-cutting and hot-pressing processes of aluminum-plastic cover sheets. The new forming process of aluminum-plastic cover sheet adopts the method of punching and hot pressing. That is, the punching station and the hot pressing station are combined into one, which can well solve the problems of die cutting points and the recycling of leftover materials in the traditional process. Aluminium Flip Off Seals Molding process plan of aluminum plastic cover: The forming process principle of the easy-open lid finished product. In this proces...
