Thermoforming transforms thermoplastics through a series of processes, including heat, vacuum, and pressure, applied to a plastic sheet material. It utilizes a variety of machines to produce plastic products, including high-speed in-line thermoforming lines with robotic automation, light-gauge roll-fed machines, and larger sheet-fed machines for heavy-gauge products. This process allows parts to be produced with lower production costs and may not require additional machining or tooling. It is a popular option for manufacturing components such as clamshells, blisters, automotive appliques, cases, reusable totes/trays, bumpers, and covers. Thermoforming is also an efficient way to create intricate shapes from plastic sheet while keeping costs low. The Thermoforming Process Thermoforming begins with plastic sheet, typically from .005” to .750” thick, that is heated and formed into the desired shape. This is done using a vacuum, air pressure, or mechanical force. After the plastic has cooled, it is trimmed, and any additional features (such as holes) are added using specialty tools such as high-speed CNC machining, high-precision robotic trimming, and routers. In many cases, with light-gauge inline thermoforming, the parts are finished and ready to use when they come off the machine. For heavy-gauge applications, the part can be used in its application once the desired modifications have been made. In either case, the same process can be repeated multiple times to produce batches of parts with identical shapes and sizes. Thermoforming Equipment Thermoforming requires specialized equipment to heat and form plastic sheet. At a minimum, this includes an oven, a vacuum source, and a forming tool. The oven is used to heat the thermoplastic until it is malleable enough to be shaped by the vacuum over or into the forming tool. Thermoforming Materials Thermoplastics are known for their durability, strength, and resistance to heat and chemicals, making them ideal for many applications. Thermoforming is often used with different types of thermoplastics, including variations of ABS (Acrylonitrile Butadiene Styrene), HIPS (high impact polystyrene), PET (polyethylene terephthalate), and PVC (Polyvinyl Chloride). These materials are available in various colors and can be modified to meet specific requirements. Thermoforming Applications Thermoforming is used in various industries, including medical, automotive, consumer products, and aerospace. This process offers them great flexibility in terms of shape and design possibilities. Here are thermoforming’s most common applications per industry: Medical: medical device trays, unit dose packaging, blisters, and transport trays. Automotive: interior and exterior appliques and trim components, mud flaps, and dunnage/tray systems. Consumer products: clamshell and blister packaging, gift sets, warehouse club packs, and Point-Of-Purchase (POP) displays. Electronics: ESD packaging, assembly systems, handling trays, inventory control systems, and Radom or cellular antenna components. Thermoforming continues to evolve with advances in technology and materials science. As new thermoplastics become available, manufacturers can create more intricate shapes while keeping production costs low. It’s an efficient way to create complex products from plastic sheet and will continue to be an important process serving many industries. Advantages of Thermoforming Thermoforming has become a popular choice for manufacturing many products, serving a variety of industries. This is because the process offers several advantages compared to other forming techniques. Cost-Effective With shorter design and tooling lead times and less expensive tooling, thermoforming can be a cost-effective solution for manufacturers. Versatile Thermoformed parts can be created in almost any shape with a wide range of materials and colors. This makes it ideal for applications that require complex shapes or unique finishes. Durable Thermoplastic materials are known for their strength and resistance to heat, chemicals, and impacts. This makes them suitable for use in harsh environments where other materials may not hold up over time.
