Thermoforming is a versatile and cost-effective manufacturing method to create plastic parts and products. One key consideration in the process is choosing between heavy gauge and light gauge materials, which refer to the plastic sheet’s thickness. Both options have distinct benefits, contingent upon the specific project application and requirements. In this blog article, we will examine the distinctions between heavy and light gauge thermoforming. We will particularly explore their advantages and applications for which each is ideal. Heavy Gauge Thermoforming Heavy gauge thermoforming is a manufacturing process that involves heating a thick thermoplastic sheet until it becomes pliable. The sheet often ranges from 0.050” to 0.75” in thickness and can be made of various materials, including polycarbonate and acrylic. The process starts with a flat sheet of thermoplastic material loaded into a heating chamber and heated until it becomes soft. The softened sheet is then placed onto a mold or tool, which applies vacuum and/or pressure to form the plastic into the desired shape. Once the plastic has cooled and solidified, it is removed from the mold and trimmed to the final structure. Advantages Here are several benefits of utilizing heavy gauge thermoforming: Ability to produce less waste compared to injection molding or machining Capacity to make large, durable, and intricately shaped components Capacity to work with a variety of materials, such as high-temperature polymers and reinforced composites Ability to generate intricate geometry and detailed drawings Personalized surface finishes and hues Superior durability and impact resistance Comparatively low tooling costs to other manufacturing processes Applications Heavy gauge thermoforming is a versatile manufacturing process used in various applications across many industries. Its ability to produce large, complex, and durable parts with lower tooling costs makes it an attractive option for many applications, including the following: Aerospace components: interior and exterior parts for aircraft, including cockpit panels, cabin components, and outer covers Automotive parts: door panels, dashboards, exterior body panels, and interior trims Consumer products: electronics covers, appliances, toys, and recreational equipment Industrial equipment: enclosures and covers for industrial equipment such as air compressors, generators, and machinery Medical devices: protective covers, enclosures, and housings for medical devices like MRI machines, surgical equipment, and X-ray machines Light Gauge Thermoforming Light gauge thermoforming produces parts using thin plastic sheets typically ranging from 0.005” to 0.050” in thickness. Like heavy gauge thermoforming, it involves heating the plastic sheet until it is pliable enough to be shaped by the vacuum over or into a forming tool. The desired shape is formed and, once the part has cooled, excess plastic is trimmed away. It is a highly efficient and cost-effective process for producing large volumes of small to medium-sized parts with short lead times and lower tooling costs. In addition, the thin-gauge plastic used in the process is typically made from materials like polyethylene terephthalate (PET), polystyrene (PS), and polyvinyl chloride (PVC). Advantages The following are the advantages of light gauge thermoforming: High efficiency and cost-effectiveness for producing large volumes Wide range of customization options of parts for unique product dimensions and branding requirements Lightweight parts and products Short lead times and quick turnaround times Minimal material waste Applications The versatility of light gauge thermoforming allows it to produce plastic parts and products, such as trays, clamshells, lids, and blister packs. Here are other common applications of the process in various industries: Automotive parts: interior trim, door panels, and exterior appliques Consumer goods: packaging, toys / games, and household items such as storage containers and organizers Electronics: cases, covers, and enclosures for electronic devices such as smartphones, tablets, and laptops Food packaging: trays, cups, and containers Medical packaging: trays and containers for medical devices and supplies Choose Jamestown Plastics for Premium Custom Plastic Products At Jamestown Plastics, we take pride in consistently delivering superior plastic solutions that meet and exceed our customers’ expectations!
