Thermoplastic injection molding is a common process used for the mass production of parts by using specialized machines. The technique works by injecting molten thermoplastic resin into a mold under high pressure, where it is held until cooled into solid form. If you have ever been curious to learn more about this important process, then you are in luck! Read through this guide and discover what is possible with thermoplastic injection molding.
You’ve designed your part, created the tooling, and are ready to begin the plastic injection molding process. But then, there is a change of plans. Rather than using ABS plastic, you will now be making the parts out of nylon. No problem. Just have some nylon shipped to the manufacturer and you’re good to go, right?
If you’ve ever flipped open a bottle of ketchup or tube of toothpaste, you’ve used a living hinge. A living hinge is formed as an extension of the base and cap material, which in many cases is polypropylene plastic. This thin piece of material between the base and cap is flexible, allowing the cap to be bent out of the way as the contents of the container are dispensed and then returned to the closed position. Living hinges can be created in a number of ways, but one of the most cost-effective methods is plastic injection molding.
In order to put out high-quality products, you need high-quality small plastic parts. As a leading small plastic parts manufacturer in Denver for more than two decades, we know what companies can and should expect from their provider. We also know that accepting anything less than the best means you may be sacrificing the quality of your finished product. So we'll point out a few things to look for as you begin your next project.
Design for manufacturing (DFM) is an approach to product development that emphasizes the importance of designing a product in such a way that it is easy to manufacture. Also known as design for manufacturability, it is used in a wide range of engineering disciplines, including the injection molding of small plastic parts. Through the smart application of DFM principles to everything from the raw materials used to dimensional tolerances to the number of components in a finished part, companies can often produce more parts faster and at a lower cost.
One of the keys to the accurate and efficient creation of small plastic parts is having a mold that is perfectly designed for the task at hand. There was a time when toolmakers were generalists who could create a mold to meet any specs. Today, however, with advances in everything from the design of parts to the materials used to make them, that’s no longer the case.
