Explaining Compression Molding

by Nice Rapid | Feb 10,2021 | Compression Molding

One of the many means of manufacturing procedures out there is compression molding. The process consists of creating products using heated molds on molten materials. The charge of material could be anything, from metals to plastics. Today we will explain how this works and the best projects where we can apply this technique.

Step-by-step Compression Molding

The first step you need to work on is creating the mold. The tooling can be done using machining procedures or modern 3D printing techniques. After that, you need to set up the equipment that will create the product. The data that needs to be used here regulates the mold's heat, the time it takes to place a full charge, and more.

When you are finally done with that part is time to choose the material you'll be working with, as well as the amount you'll need to bring your idea to life. The setting of this stage is crucial to avoid mistakes such as flashes. When the charge is ready, it needs to be placed at the bottom of the mold, and then you can begin to compress.

Now you finally have a finished product in your hands. But the work is far from finished. After you release the part from the mold, you will have to clean it. Not getting rid of the flash means the part won't work. If you are working on a multilayered product that requires assembly, this is crucial. After that, you can go to the application stage.

Industrial Applications of Compression Molding

Application is just another way of saying "putting our product to work." The applications of compression molding have a wide range of use in many industries around the world. Although we mentioned metals earlier, the fact is that modern manufacturing is centered on working with various plastic resins since they have proven to be more reliable and effective.

You can see compression molded parts in action in many vehicles such as cars, planes, and boats. Most of these are entirely made of industrial fibers and high-end polymers these days, from their control panels to specific sections of their inner machinery. You will notice tons of applications in toys, computer equipment, keypads, gaming controllers, smart devices, and more.

Everyday Applications of Compression Molding

When it comes to everyday utensils, we can pinpoint that nearly 80% of the items in any kitchen are compression molded. Things like bowls, plates, cups, and glasses can achieve a very high-end look with this manufacturing procedure rivaling in practicality the finest silverware out there. We can also affirm that the safety industry pursues these types of products in high quantities.

It makes sense when you consider the functional properties and the insulation capacities of many plastic resins. Technicians always use implements such as faceplates, gloves, boots, switches, sockets, and more, and they have a short lifespan for the people who make a living in these industries.
