Thick sheet thermoforming Similar to thin sheet thermoforming, this process involves heating a positioned sheet to a softened state in an oven. A thermoforming mold then creates a sealed space around the sheet, and the air inside the mold cavity is instantly evacuated. This causes the sheet to adhere tightly to the mold surface, cooling and setting to produce the finished product. So, what are the advantages of thermoformed parts? Let's take a brief look!
I. Engineering Economy
In the packaging manufacturing industry, unless you're using cardboard, thick sheet thermoforming technology is unmatched by other processing methods. Products made from composite sheets, foamed sheets, and printed sheets can be produced by simply changing the mold instead of changing the thick sheet thermoforming machinery. Products with very thin walls can be produced using high-melt-viscosity sheets, while injection molding of the same wall thickness requires low-melt-viscosity granules. For small quantities of plastic parts, favorable mold costs are Thick sheet thermoforming another advantage of processing, while for large quantities of parts, the ability to achieve very thin wall thicknesses and the high output of thermoforming machines are very advantageous.
II. Wide Range of Processable Materials
Thick sheet thermoforming The process can produce very small parts, such as packaging for pills or watch batteries, as well as very large parts, such as garden ponds 3-5m long. The thickness of the molding material can range from 0.05 to 15mm; for foamed materials, the thickness can reach 60mm. Any thermoplastic or material with similar properties can be thermoformed.
