Have you ever tapped your fingertips on an object to be sure whether it is glass or plastic? Some plastics are so seductive, they have the appearance of glass mastered. You can see right through, with clarity, these glorious products. Injection molding plastic allows for a versatility in material choice. Plastic resins such as polycarbonate, acrylic, nylon, ABS, K-resin, and more can all give your product the clarity it needs.
Which Clear Plastic Resins is Right for Injection Molding?
Nylacarb is home to expert engineering that can help choose the perfect material, mold, and molding process to ensure the outcome of a beautiful clear product; free of yellow tinting or fogginess. Finding the best material requires an analysis of many aspects, including but not limited to:
- Chemical resistance
- Temperature durability
- Strength needs
- Aesthetic needs
- FDA, or medical grade requirements
Clear Plastic, Like Acrylic
Let’s take acrylic as an example of a clear resin that is great for transparent products. Acrylic is often used as a scratch resistant, durable, glass alternative. You will find it in places like refrigerator doors and lenses. Although more durable than glass, if you are looking for a stronger and transparent plastic, a better option might be polycarbonate. When working with acrylic, sharp edges should be avoided. We talked about in designing all corners with a radius (link to blog) in our last blog, this will help in increasing the strength of the plastic part.
Molding Plastic for a Crystal Clear Finished Product
When it comes to molding clear plastic, mold conditions need to be optimal. Exceptional mold processing reduces common clear plastic hiccups. These hiccups include air bubbles, silver streaking, yellow-tinting, and flow marks. All of these potential problems are foreseeable and preventable with perfecting the mold and the injection mold process. Our team is equipped, and experienced. We have made mistakes, and are familiar with how to prevent them from occurring. We have over 100 years of combined experience in the plastic injection molding industry.
