Thermoforming, a stalwart in the realm of plastics manufacturing, often doesn’t get the recognition it deserves. Let’s change that narrative and delve into the fascinating world of thermoforming.
Thermoforming Process: A Comprehensive Overview
The Power of Thermoforming
Thermoforming is a versatile process that can be used to create everything from lightweight, thin-wall packaging to heavy-gauge panels and parts for a plethora of industries, including automotive, agriculture, construction, medical, and aerospace.
Vacuum Forming vs. Pressure Forming
In vacuum forming, a heated, pliable plastic sheet is drawn against the mold contours by vacuum pressure, ideal for simple designs. On the other hand, pressure forming, involving additional air pressure, allows for rich textures and complex part geometry. The choice depends on your part requirements.
The Evolution of Thermoform Tooling
Thermoform tooling has evolved significantly over the years, costing roughly a quarter of injection mold tooling. This offers a substantial economic benefit, particularly for short-run jobs.
Heavy-Gauge Thermoforming in Industries
The medical plastics sector has become a significant market for heavy-gauge thermoforming, producing items like monitor covers and equipment panels. Industries like recreational vehicles, boats, and agricultural and construction equipment appreciate the durability and light weight of plastic panels compared to metal.
The Future of Thermoforming
The Rise of Pressure Forming
Industry veteran Jay Waddell believes that pressure forming is currently underestimated and is gradually encroaching on injection molding markets, especially for shorter runs. The process offers a lot of design freedom, and there’s a notable increase in firms now embracing pressure forming.
Regional Nature of Heavy-Gauge Forming
Since heavy-gauge forming creates large parts that are costly to ship, the companies serving these markets tend to be more regional. They usually serve local customers with production runs ranging from 500 to 10,000 parts. Heavy-gauge competes primarily with processes such as rotational molding, structural foam, and metal forming.
