While there are many options available for injection molding, the most solid and dependable for quick, sturdy, safe and precision molding is still thermoplastic elastomers. There are many reasons why thermoplastic injection molding is still the go-to, if you need precise but large-scale continuous output for production, with a decreased margin of error.
- Versatility! Having the ability to combine multiple parts and types of plastics, it is one of the most reliable materials to work with. The bonus of co-injection of other plastics can add to the end product’s resilience. It is also possible to use filler in plastic injection molding, which is not possible with other methods. These fillers enhance strength and long-term durability. Currently, many companies in the automotive industry are opting for lightweight plastics over metal for various car parts, with almost no difference in strength and longevity.
- Detail and Consistency! The pressure levels during thermoplastic injection molding are one of the highest of any other material. During this process, the plastic is pressed the hardest against the mold, which allows for fine precision designs to come out correctly and the same every time.
- Automation! Majority of the injection molding process is performed by machines and programmed robotics, which one operator can easily watch over. This considerable labor cut allows for reduced overhead and a largely hands-off assembly line of production. Assistance from design programs like CAD, the machines can help monitor the internal precision during the injection process.
- Reduced Waste and Bottom Line! Thermoplastics create much less waste, and any excess parts left over after the injection process are ground up and reused. This creates a cycle of continuously reusable base product material without the issue of deterioration. At the end of the injection molding process, the end product has a finished appearance due to the thermoplastics. This means that there is virtually no work required after the injection molding process is complete.
There are many materials available for injection molding, and they all have their strengths and weaknesses. Be aware of your company’s needs and what material creation process will work best for your product.
