Injection mold processing is to add the plastic mold, and mold along two vertical axis rotation and heating, a mould of plastic under the effect of gravity and thermal energy, evenly coated, gradually melt adhesive on the entire surface of the cavity, forming the shape of the required, to made by cooling.
Compared with the traditional blow molding and injection molding processes, the rolling molding process has the following advantages:
1. Cost advantage: in the rolling molding process, only the strength of the frame is required to support the weight of materials, molds and the frame itself, so as to prevent material leakage.And materials in the molding process, in addition to the natural gravity, almost not affected by any external force, thus fully with the tools and processing manufacturing convenience, short cycle, low cost advantage.
2. Quality advantage.The quality and structure of the products are more stable because of no internal stress during the whole production process.
3. Flexible and changeable advantages.The machine mould of roll molding process is easy to manufacture and the price is low.
4. Advantages of personalized design.Roll forming process of the product is easy to change color, hollow and can do no welding (seamless), can be done on the product surface treatment pattern, the effect of wood, stone and metal, meet the personalized needs of consumers for goods in modern society.
The products produced by this process are: fuel tank, water tank, mechanical shell, fender, etc.The main alternatives are metal and fiberglass products.
Injection molding is a process based on micro-manufacturing techniques such as LIGA, and there are many other methods.And journalist on a injection molding process is Mr Output required by the model, which is commonly known as the "mold", then liquid plastic perfusion in the mould, the last in the separation of the end products you need.For example, some plastic toys, too many products.
