Plastic Injection Molding for Windows and Doors Industry

Plastic Injection Molding for Windows and Doors Industry Injection molding has shaken up the manufacturing industry. Now, numerous mechanical part scan be produced at a high-quality and relatively lower cost.

What are injection molded plastics?Basically, injection-molded plastics are produced by the injection of molten plastic into a mold cavity. After which the molten plastic on cooling takes the shape of the mold.

How it Works The plastic injection molding machine consists of three main work units; the injection, clamping and mold units. The production process is quite straightforward. Plastic pellets are passed into the injection unit and then heated to a certain high temperature. At this point, the solid pellets; which are now molten due to the high temperature are injected into a mold cavity similar to the shape of the required window or door plastic part. At this stage, the clamping unit holds the molten plastic pellets into the mold as it cools. In order to ensure uniformity, a “dwelling period”is employed to ensure that the molds are completely filled up before the cooling process begins. With this technique, tons of window and door products and parts are often produced within a short period of time.

Three Major Types of Injection Molding Machines Though these machines have a similar mode of operation, they differ in the size of plastic parts each can produce, and also the efficiency of production.

All Electric Machine Best for short plastic injections. That is, it is most efficient in the production of small molded plastic parts.

Fully Hydraulic Machines This machine uses a very high clamping force which is efficient in the production of larger plastic parts.

Hybrid Machines They have higher energy efficiency and can be used in the production of different sizes of plastic parts.

Advantages of Plastic Injection Molding in the Window and Door Industry  Plastic injection molding ticks both boxes of precision and efficiency - which are major factors to consider in window and door production.  Parts such as latches, window stops, locks, and other window and door parts can bemass-produced with the same mold through injection molding.

 Unused or excess plastic pellets can also be saved for future use making sure of zero wastage.  Through injection molding, shapes and symbols which are otherwise too costly or complex to machine individually can be easily produced.  Higher production of plastic parts at a relatively lower cost.

Conclusion

It's no news that the injection molding industry is constantly evolving. This is due partly to increasing demand for molded parts,and also the favorable cost efficiency of production.
