Thermoforming is a versatile process used in many industries, from food packaging to aerospace and auto parts manufacturing. Since most industries work with thermoplastics at some point, understanding thermoforming is essential.

There are two main types of sheets: thin-gauge and thick-gauge. Thin-gauge sheets are commonly used for rigid, disposable packaging, while thick-gauge sheets have broader applications. These include durable surfaces for automobiles, window enclosures, building products, signs, and electronic equipment.

The possibilities for thermoformed plastic products are vast, but the process is not one-size-fits-all. The right material, techniques, and expertise are key to creating optimal results for each application.

Recent developments in thermoforming include advancements in non-composite sheets that add value to specific industries. Additionally, thick sheets are sometimes converted into composite sheets, resulting in thinner-walled parts that are ideal for weight-sensitive applications.

Excelite’s plastic fabrication center is located in Suzhou, China, supplying a wide range of polycarbonate sheets and offering plastic fabrication services globally, including to the USA, Mexico, Chile, UAE, France, Germany, and Singapore. We also have an overseas branch in Victoria, Australia, and provide polycarbonate sheets with nationwide shipping across the country.

People often ask which plastic is best for vacuum forming. Typically, vacuum forming uses thermoplastics, which become flexible at certain temperatures and solidify once cooled. One commonly used material is high-impact polystyrene (HIPS), known for its flexibility and ability to be molded into almost any shape.

Polycarbonate (PC) is another popular choice for vacuum forming. It’s extremely tough and resistant to flames, chemicals, and water, making it ideal for medical equipment and food manufacturing machinery. It’s also easy to mold, trim, and fabricate.

Acrylic (PMMA) is another widely used plastic for vacuum forming and thermoforming due to its versatility and ease of use.

One of the key advantages of vacuum forming is its cost-effectiveness. While the initial machinery investment may be significant, it is highly versatile and can produce a wide variety of products. Additionally, once molds are made, they can be reused repeatedly for mass production, making vacuum forming one of the most affordable methods of plastic fabrication.

Pressure forming provides a contrast to vacuum forming. The use of high pressure to push and pull the plastic tightly against the mold allows for greater precision, detail, and sharpness, while still being suitable for forming large plastic parts with ease.
