Thermoforming and Vacuum Forming

Thermoforming and vacuum forming are fast and inexpensive technologies for manufacturing versatile products by shaping hot thermoplastic sheets around a mold. Once the sheets are drawn onto the mold, any remaining air is sucked out of them, pulling the material tightly against the mold to ensure consistent definition in the final product. Once the product is taken off the mold, the excess plastic is trimmed off and recycled.

It requires less lead time and tooling costs than traditional manufacturing techniques like injection molding or machining while also offering a lower part cost than 3D printing. Although thermoforming has more design limitations than these technologies, it offers excellent value for compatible projects.

With bed sizes up to 4’ x 4’, our thermoforming services are ideal for a range of products, from custom trays and packaging to large panels, displays and housings.

Durable Thermoplastics

Real thermoplastics are strong, durable and inexpensive compared to 3D printed materials. RapidMade offers an extensive range of plastics for thermoforming, such as PETG, HIPS, ABS, Styrene, PC, Acrylic and many more, in thicknesses ranging from 0.020" to 0.250" (0.5 mm to .6.5 mm).

With so many material options, thermoformed products are able to meet a host of mechanical and aesthetic demands, from conductivity and heat resistance to FDA food-grade certifications. Thermoformed parts can be rigid, flexible, translucent or opaque. This versatility has led to applications in a variety of industries, including food, medical, electronics and manufacturing industries.

Thermoforming and 3D Printed Tooling: Better Together

Traditionally, thermoforming molds are milled from urethane or aluminum. This can be expensive, especially for small- to medium-sized parts, and can take 1-3 weeks to produce. By using 3D printed molds made with the HP Multi Jet Fusion (MJF), however, RapidMade can create durable molds for thermoforming in under 48 hours at a savings of up to 50% when compared to machining.

With a relatively high temperature resistance, the Nylon PA-12 used by MJF printing is excellent for thermoforming. It doesn’t bond with other materials and MJF molds do not require additional finishing for opaque parts. Molds for translucent parts may need a minimal amount of filling and sanding, though they will still offer substantial time and cost savings over machining in most cases. Moreover, 3D printed molds can easily produce undercuts and other complex shapes that would be difficult or impossible to machine.

Not only does this allow us to produce parts faster, it also makes it easy to prototype your product. Once prototypes are made, adjustments are cheap and quick, allowing you to get more iterations during your product development cycles. The time and cost savings of 3D printed molding allow thermoforming to be an economical option in an even wider range of situations throughout your product life cycle. Click here to find out more!

RapidMade can quickly create inexpensive custom branding or visual textures for signs, packaging, retail displays and more by printing high-resolution 2D images onto sheet plastic and calibrating 3D tooling to match.


Thermoforming Materials and Applications

Thermoforming is compatible with a variety of materials that can achieve a wide range of thermal, mechanical and chemical properties. Below, we’ve put together a little guide to the materials we commonly use for thermoforming and some of their ideal applications. Though we provide some examples here, these materials can be used for many different products. If you’d like more information about any of the materials listed below, reach out to us at info@rapidmade.com or at 503-943-2781.

 

HIPS (Polystyrene)

Our most commonly-used material. Inexpensive, functional material that is food safe at room temperature but can be brittle at low temperatures and can off-gas at higher temperatures. Used for packaging trays, covers and light-duty structural pieces.

HIPS Data Sheet

PETG (Polyethylene Terephthalate) (Polyester)

Moderately inexpensive material with good water and oxygen barriers. Able to stand up to substantially lower temperatures than HIPS. Often used for food-safe applications, freezer packaging and water bottles.

PETG Data Sheet

ABS (Acrylonitrile Butadiene Styrene)

Medium-cost impact-resistant engineering plastic which can be flame retardant or UV resistant when blended with other materials. Used for high-end packaging and moderate-load structural components.

PC (Polycarbonate)

Medium- to high-cost engineering plastic with high impact and temperature resistance, plus options for UV and scratch resistance. Often used for glass replacements on phones, TVs, lights or glasses. Applicable in a wide range of high-temp situations.

PC Data Sheet

PE, HDPE or LDPE (Polyethylene)

Moderately hard, inexpensive plastic with high chemical resistance. Does not off-gas at high temperatures. Chemical and thermal durability makes it well-suited for chemical-resistant containers.

PE Data Sheet

PP (Polypropylene)

Moderately-priced alternative to PE which improves thermal and mechanical properties but decreases chemical resistance. Can be used as an engineering plastic. Used for chemical- and thermal-resistant applications, including food contact.

PP Data Sheet

 

PVC (Polyvinyl Chloride)

Hard engineering plastic with strong mechanical properties as well as high chemical and electrical resistance. Can be made rigid or flexible. Used for chemical-resistant and food-grade containers.

PVC Data Sheet

Acrylic

An inexpensive, rigid and brittle plastic with relatively high UV resistance. More difficult to form than other plastics. Not intended for tight bends or details. UV resistance makes it well-suited to outdoor applications.
