Some problems in thermoforming are color changes and bad heating. Knowing about these problems can help stop issues when making cups.
Thermoforming is a common way to make cups and food packaging. This method uses heat and pressure to shape plastic sheets. Factories like this process because it makes strong and light products fast. There are several main steps in making cups with thermoforming:
Plastic sheet extrusion: Workers change plastic resins like PP or PET into flat sheets.
Heating: Machines warm the sheets until they bend easily.
Forming: The warm sheets are shaped into cup molds by vacuum, pressure, or force.
Cooling: The cups are cooled so they keep their shape.
Trimming: Machines cut off extra plastic for smooth edges.
Stacking and packaging: Finished cups are stacked and packed for shipping.
This process lets factories make lots of cups that look the same.
Picking the right material is very important in plastic thermoforming. Each material has special features that change how the cup turns out. Some plastics can handle heat better. Others are more bendy or clear. The right material makes cups stronger, better looking, and safer for food.
Hengfeng’s machines work with many types of thermoforming materials like PE, PP, PET, and PLA. This helps companies switch materials easily and meet different needs. Hengfeng’s equipment fits with other machines, making work faster and more exact.
Factories need to think about cost, strength, and how the material acts when heated and shaped. Bad choices can cause problems like color changes, burning, wrinkles, or misshaped cups. Some common problems in thermoforming are:
Discoloration
Scorching
Wrinkling
Distortion
White corners
Incomplete formations
The table below lists some usual problems and why they happen:
