I believe everyone knows bottle caps, so do you know how to make bottle caps? Today, Savi, the manufacturer of upper and lower cap assembly machines, will tell you about bottle caps.
The hydraulic compression molding technique for making urea\/phenolic caps is to place a thermoset material into the cavity of a preheated mold and press it between 2 platens. The combined action of heat and pressure results in cross-linking in the material and the formation of small molecules, which causes the compound to fill the mold cavity and harden. After a period of time, the mold is opened and the molded product is removed.
1. Fix the necessary mold on the die head. 2. Load the raw material into the hopper. 3. Inject the molten material into the mold. 4. Open the mold after cooling. 5. Injection parts. 6. Organization.
The bottle cap can be made of thermosetting material (urea-formaldehyde resin, phenolic resin) or thermoplastic material (polypropylene, high impact polystyrene, high density polyethylene, etc.).).Plastic bottle caps are widely used for packaging liquid bottles. For decades, the plastics market has been growing and rising, becoming the foundation of great powers. The industry itself is growing rapidly, as is per capita consumption. Compared to the previous decade, plastics have increased in many ways. There is no No doubt, plastic is important in all fields of activity. It helps to replace and save scarce natural resources, which is an integral part of our daily life.
