2021-11-11
Thermoforming is a prevalent manufacturing process utilized across a variety of plastic disposable cup applications for full-scale designs and shorter production runs. The process involves a tool or molds. Starting with film heating, product forming, tool cooling, through stacking with downstream automated carton packaging. The thermoforming cup mold is precisely machined to form, punch, cut, trim and stack the features of the desired cups. The precision designed cup thermoforming tool or mold, with maximized mold layout, is critical to optimize the product output and reduce scrap rate while offering high-speed and precise cutting tolerance during thermoforming cup mass production.

Types of Thermoforming Tools for Cups

The most common type of forming tools used for plastic disposable cups is In-Mold Cutting. It is also known as Cut in place molds or trim in place molds - integrating forming and cutting (or trimming) into a single station. Using cut in molds, you not only achieve accuracy in the cutting alignment, but also enhance stability for each cup weight. Besides plastic disposable cups, dairy containers also require close cutting tolerances, high product quality and fully automated processes.
