Meaning
Thin-film transducers measure the distribution of pressure across the contact surfaces of a mould. A tactile sensor film is placed between the mould halves to map the clamping force and identify areas of uneven pressure. It changes colour or sends an electronic signal to show where the tool is touching and where it is not.
This tool is used during the setup phase to ensure that the parting line is sealing correctly.
Pressure Mapping
Visualizing the contact pattern allows the technician to see the high spots on the mould face. If the tactile sensor film shows light or missing areas, it indicates that the mould is not closing evenly.
Flash Prevention
Identifying poor contact before the resin is injected saves time and reduces scrap. By using the tactile sensor film, the moulder can adjust the clamp or the tool itself to achieve a perfect seal. This is especially useful for complex parting lines that are difficult to check with traditional methods.
Alignment Verification
Checking the squareness of the platens and the tool is another use for the material. A tactile sensor film can reveal if the machine is applying force more on one side than the other. This information is used to level the machine and ensure a long life for the mould and the press.
Correcting these imbalances reduces the risk of cracked plates or broken tie bars. Digital versions of the film provide quantitative data that can be stored for quality audits.
