Next, we’ll explain the characteristics of thick‑plate thermoforming.

　　1. Definition of thick-sheet thermoforming

　　 Thick-sheet thermoforming Also known as thick‑sheet thermoforming, this process uses raw materials thicker than 2 mm, which cannot be formed by fully automatic machinery; therefore, it requires the use of a semi‑automatic thermoforming machine specifically designed for thick sheets.

　　2. Thick-plate-absorbing plastic material

　　The materials primarily used in thick‑plate thermoforming include ABS, acrylic, PETG, PVC, PC, PP, PE, PS in various colors, as well as a range of modified plastics available in solid sheets, textured sheets, and transparent sheets.

　　3. The Practicality of Thick-Plate Thermoforming

　　 Thick-sheet thermoforming Molds can be used for the design and manufacturing of products such as TV rear covers, display components, medical equipment, textile machinery, automotive accessories, microelectronics, and cosmetics.

　　4. Thick-plate absorption-type products

　　Thick‑sheet thermoforming products include refrigerator inner liners, PS thermoforming, ABS thermoforming, housing thermoforming, blister‑molded shells, thick‑wall thermoforming, and PMMA thermoforming, among others. Our company’s thick‑sheet thermoformed products are widely used in medical equipment, food‑processing machinery, instrument housings, and electrical appliances, as well as in advertising light boxes and lighting fixtures. For the refrigeration industry, our thick‑sheet thermoformed components can replace injection molding, not only reducing costly mold expenses but also offering an alternative to conventional manufacturing methods. With refined production processes, rapid turnaround times, and superior quality, these products deliver exceptional performance.

　　5. Production Technologies and Processes for Thick-Plate Thermoforming

　　1. Mold fabrication and machining: Since each customer’s product has its own specific specifications, a plastic mold must be manufactured prior to production. In this case, the mold is typically made from plaster; among these options, plaster molds are the most cost‑effective, followed by copper‑plated molds, with aluminum molds being the most expensive. When fabricating the mold, it should be allowed to dry naturally or undergo artificial drying, and surface treatment should be applied according to the particular requirements of the product’s finish.

　　2. Once the mold is completely dry, place it on the iron plate at the top of the vacuum chamber. Then, according to the mold’s dimensions, position it in the appropriately sized fixture and insert paper into the heated wooden box to secure the machining process.

　　3. Place the softened plastic sheet and the wooden cabinet inside the vacuum chamber, then activate the suction switch to evacuate the air from the chamber. Once the plastic sheet has cooled, the mold takes shape.

　　4. Finishing: The finished product is refined and assembled into a complete item.
