Plastic thermoforming is a versatile manufacturing process that has revolutionized the production...
Thermoforming is a widely used manufacturing process that involves heating plastic to a pliable forming temperature, shaping it into a specific form, and trimming it to create a usable product. The choice of which type of plastic resin is crucial in this process, as it directly impacts the characteristics and performance of the final product.
Thermoplastic resins offer various characteristics and applications, making them integral to numerous industries and products we encounter daily. Each type of resin brings its own set of advantages, allowing manufacturers to tailor their material selection to meet specific product requirements. At Vantage Plastics and our Lotis Technologies injection molding business unit, we also develop unique blends of thermoplastics to solve unique issues that are often encountered.
