Heavy Gauge Thermoforming

Thermoforming Process

Thermoforming is a manufacturing process where a plastic sheet is heated to a specific pliable forming temperature based on plastic thickness, sheet size and mould complexity.

The machine then takes it from the oven, lowers the heated plastic sheet onto the mold, and applies a vacuum pressure through holes in the mold to cause the plastic to form and take on the shape of the mould. Once cooled, it is removed from the mold, trimmed to create a usable product.

The remaining sheet material is recycled for reuse. The process is then repeated with the next sheet.

Thermoforming vs Injection

Qualiplast works with customers to make sure that the technology, production processes and materials are right for each individual job. After initial discussions about your project we will provide general guidelines for selecting the appropriate process, comparing the thermoforming process with plastic injection moulding with economics in mind.

Thermoforming is considered to be one of the most versatile methods for the production of packaging materials. Thermoforming is typically used for production quantities of 250 to 3000 annually, offering reduced tooling costs/turnaround, rapid product development cycles, and parts with color, texture than can even include your company logo!

Thermoforming enables the manufacture of a wide range of custom-made products, but is especially suited for bigger objects. This process meets the requirements of companies that demand highly specific dimensions and that are quite adaptive to the wider design scope and needs of customers.

The costs involved in tooling and engineering are lower, which makes it ideal for prototype development and for low to medium production volume parts which would not be economically feasible to injection moulding which, in some cases, can have prohibitive tooling costs. As the size of the part increases, so does the disparity in tooling costs between thermoforming and injection moulding increasing the economics advantages of thermoforming.

For thermoforming, the typical tooling time is 0-8 weeks, and first production typically happens within 2 weeks. With injection moulding, tooling usually takes 12-16 weeks with up to four more weeks for production.
