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 therefore expose the products to extreme loads during development and 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.
With the help of a high-precision Balluff position measurement system, you can monitor the closing stroke of mould plates in a targeted manner. A gentle mould closure reduces wear and extends your mould's useful life.
The flat design of our BTL PF profile magnetostrictive linear position sensors, which measure without contact, is perfect for tight installation conditions on the injection moulding machine. The contact-free, unguided position encoder enables rapid unit changeovers without the need for re-alignment.
Balluff inductive distance sensors continuously monitor the tie bar extension during the process. They are insensitive to contamination and provide optimal linearity as well as high repeat accuracy.
Balluff inductive mini sensors are perfectly suited for the optimum alignment of core pulls: These ensure that the core pull is at the required end position. High-pressure resistant versions of the sensors scan the end positions directly in the hydraulic cylinder. If necessary, alternatives that are resistant to high temperatures can also be used.
Perfect closure of the clamping plates requires the correct pressure. A solid pressure sensor in a stainless steel housing from Balluff enables reliable pressure monitoring in the hydraulic cylinder. Equipped with IO-Link, the pressure sensors relay their values directly to the controller and thus let it readjust with precision.
Is the cavity completely filled with the mould material? Our high-pressure-resistant and temperature-resistant capacitive sensors reliably answer this question. They offer a great deal of mechanical stability and can be integrated directly into the mould. Thanks to their specially polished surface, the plastic does not stick.
