Withstand extreme loads in injection moulding

In injection moulding, sensors need to withstand tremendous loads. If they fail early on, the downtime comes at a high price. High-quality Balluff sensors such as displacement transducers, high-pressure-resistant and temperature-resistant capacitive sensors and pressure sensors ensure continuity. Balluff sensors are continuously optimised in our accredited in-house laboratory through Highly Accelerated Life Tests (HALT). We expose the products to extreme loads during the development phase to eliminate possible weaknesses. The durable and extremely precise technology of our sensors optimises the availability of your systems by eliminating downtimes. Its precision makes products of the highest quality possible.

Application examples

  • High-precision displacement transducers for a gentle mold closure

    High-precision displacement transducers for a gentle mold closure

    With the help of a high-precision magnetostrictive linear position sensor from Balluff you can precisely monitor the closing motion of the platen. A gentle mold closure reduces wear and extends your mold's useful life.

    Features

    • Contact-free and therefore wear-free
    • No homing necessary, immediately ready
    • Resistant to vibration, moisture and dust

  • Detecting the injection process

    Detecting the injection process

    Our BIW inductive positioning system ensures that your molds are quickly filled because the high sampling frequency and repeat accuracy measure the travel of the injection axis precisely and reliably. You can exactly calibrate the injection profile, for example, to produce high-quality, thin-wall parts.

    Features

    • Fast: High measuring frequency of 32 kHz
    • Non-contact position detection
    • High repeat accuracy

  • Continuous monitoring with inductive sensors

    Continuous monitoring with inductive sensors

    Inductive distance sensors from Balluff ensure continuous monitoring of the tie bar extension in the process. They are insensitive to contamination and provide optimal linearity as well as high repeat accuracy.

    Features

    • Distance-proportional, analog output signal
    • Measuring ranges from 0.5 to 50 mm
    • Measuring speed up to 40 m/s

  • Detect the position of core pulls

    Detect the position of core pulls

    To optimally adjust core pulls our magnetic field sensors in the mini-format are ideal. They ensure that the core pull is at the required end position and they detect the position directly at the hydraulic block cylinder. Alternately, you can use high-temperature rated sensors.

    Features

    • Designed for tight mounting locations
    • Can be fully integrated
    • Low weight
    • Wear-free position detection
    • Two teachable switching outputs via IO-Link for up to eight switchpoint
    Detect the position of core pulls

  • Continuous pressure monitoring with IO-Link

    Continuous pressure monitoring with IO-Link

    Perfect closure of the clamping plates requires the correct pressure. Reliable pressure monitoring in the hydraulic cylinder is handled by a rugged pressure sensor in a stainless steel housing. Equipped with IO-Link, the pressure sensors relay their values directly to the controller and therefore,thus let it readjust with precision.

    Features

    • Extended temperature range up to 125 °C
    • Up to 600 bar
    • Process-oriented installation

  • Measuring mold filling in RTM (Resin Transfer Molding)

    Measuring mold filling in RTM (Resin Transfer Molding)

    Our high-pressure and high temperature rated capacitive sensors reliably check whether the cavity is fully filled and the RTM is completed. They offer great mechanical stability, e.g., for lightweight construction and can be integrated directly in the tool. Their specially polished surface prevents plastics and composites from sticking.

    Features

    • Pressure rated to 150 bar
    • Temperature-resistant up to 180°C
    • Flush-mounted
