Thermoforming
Thermoforming or vacuum molding, produces strong, semi-flexible, seamless (leak-proof) inserts in a range of thicknesses designed to withstand the rigors of our customers' most demanding applications.
CDF's expertise in deep-draw thermoforming allows us to produce parts up to an unprecedented 40" deep in a variety of shapes. We use a variety of mold designs that produce cylindrical, tapered or rectangular-shaped products.
CDF thermoforms FDA-approved LDPE and HDPE for routine applications, but we also work with:
- Polypropylene for high temperature resistance
- Anti-static polyethylene for use with volatile materials
- EVOH for oxygen resistance
- Other materials upon request
CDF employs a full range of thermoforming technologies, including rotary, in-line and shuttle systems. We work closely with our customers to choose the technology that best fulfills their needs.
Why choose CDF?
CDF has been providing thermoformed plastic packaging since 1971. We have carefully refined our technique for creating a uniform thickness over an incredibly deep draw, a feat unmatched by any competitor over such a wide range of products.
Additionally, CDF prides itself on our ability to work closely with our customers to provide cost-effective, customized thermoformed plastic packaging.
How does Thermoforming work?
In thermoforming, sheets of plastic are carefully heated to soften the material. The sheets are then pressed into a mold and a vacuum is drawn to force the plastic into the shape of the mold. It is critical to maintain an even distribution of material during this process.
Thin and thick gauge Thermoforming
There are two general thermoforming process categories. Sheet thickness less than 1.5 mm (0.060 inches) is usually delivered to the thermoforming press in rolls. Thin-gauge, roll-fed thermoforming applications are dominated by rigid or semi-rigid disposable packaging. Sheet thickness greater than 3 mm (0.120 inches) is usually delivered to the forming press cut to final dimensions and stacked on pallets. Heavy- or thick-gauge, cut sheet thermoforming applications are primarily used as permanent structural components.
