Formed to a specific shape.
Thermoforming of blisters is a manufacturing process where a plastic sheet is heated to a pliable, forming temperature, formed to a specific shape in a mold, and then trimmed. The sheet, or “film” is heated in an oven to a high-enough temperature that is then stretched into or onto a mold and cooled.
In its simplest form, a small tabletop or lab size machine can be used to heat small cut sections of plastic sheet which are then stretched over a mold using a vacuum process. This method is often used for sample and prototype parts.
In complex and high-volume applications, very large production machines are utilised to heat and form the plastic sheet and trim the formed parts from the sheet in a continuous high-speed process. This method can produce many thousands of finished parts per hour depending on the machine and the mold size.
Our in house mold designing and vast experience in field of blister forming has fetched numerous awards and recognition to us.
