Advantages of TPE Injection Molding
Reasons to Use TPE Injection Molding
-
Free-form Design
Users have a great deal of design freedom when using TPE injection molding. TPEs can be formed into complex structures, such as undercuts, thin walls, and complex geometries, without the need for additional processing.
-
Soft-touch Experience
TPEs are perfect for applications where tactile qualities are critical since they provide a soft, rubber-like feel. TPEs’ elasticity offers a cozy and ergonomic user experience, increasing the allure of the product.
-
Capability for Overmolding
Overmolding, or encasing one material inside another, is possible using TPE injection molding. By combining stiff and flexible materials in a single component, this approach enhances functionality and boosts product performance.
-
Chemical Defense
TPEs are suited for applications involving exposure to oils, greases, solvents, and other chemicals because they have great chemical resistance.
-
Versatility
TPEs, which combine elastomer and thermoplastic properties, are renowned for their versatility.
-
Cost-effectiveness
When compared to other procedures, TPE injection molding is more affordable. Because of its high efficiency, the injection molding technique enables quick production cycles, which lowers overall manufacturing costs.
-
Reduction of Secondary Operations
Since the parts may be molded to their final shape, TPE injection molding reduces the need for additional procedures like trimming, cutting, or machining.
-
Excellent Aged Properties
TPEs have exceptional aging characteristics, maintaining their functionality and morphological characteristics throughout time.
- Material Types of TPE
| Type of TPE | Shore Hardness Scale | Temp. Use Permanent. Limit |
| TPV | 50D to 40A | 135℃ |
| TPU | 80D to 65A | 120℃ |
| TPO | 80D to 75A | 120℃ |
| SBC | 50D to 15A | 110℃ |
| COPE | 80D to 90A | 140℃ |
| PEBA | 75D to 80A | 170℃ |

Comparing TPEs to TPUs, it can be said that TPEs are often softer and more flexible. TPU is also a simpler material to print with because it is harder while still remaining flexible.
Though, due to its longer presence on the market, TPE is more widely used. As contrast to TPU, TPE is typically more affordable.
NDDMold, TPE have also been given the GRAS (Generally Recognized as Safe) designation by the FDA.
Yes!
These are commonly utilized in applications for waterproof electronics.
