Thermoforming, a technique utilized for shaping plastic sheets, makes use of a selection of molds, which includes cast aluminum molds, composite molds, machined aluminum molds and wood patterns. This is a ten billion dollar market in North America, the continent that consumes one hundred million pounds of plastics annually, or one third of the entire world’s plastic consumption.

The first kind, composite molds are durable with an extended shelf life, are a less pricey selection and are able to produce higher quality pieces. These molds are not temperature controlled, so are very good in most circumstances except when higher volume production is desired. Composite molds are typically made with liquid resins that are solidified.

The next kind, cast aluminum molds, are a high-priced selection but supply temperature management options. This type is produced at a foundry and usually come equipped with temperature control lines. These lines are utilized to control the heat of the plastic, which can speed up production.

Machined aluminum molds are one more kind employed in thermoforming. This mold, created from a block of aluminum, is helpful for shallow or thin parts such as trays or some packaging. Similar to cast aluminum molds, this type is also a somewhat more pricey choice.

The final type of mold is wood patterns. This selection is inexpensive and usually utilized in the early stages of the process of thermoforming. This kind allows the design to be tweaked easily and checked for performance and quality. Once the producer is happy with the results, the wood pattern is sent off to be made into one of the other kinds of molds for production.

The process of thermoforming was initially utilized by the Romans a long time ago to make food utensils. These individuals did not have the thermoformed plastics we have right now, but instead heated tortoise shells with hot oil and shaped them to desired end items. This approach has been developing over the years and will continue to be utilized in many years to come.
