🔄 From sprue back to production!
At BJB, sprues from our injection moulding process get their next use right here in our factory. ⚙️
How does it work? The sprues are fed into the bottom of our grinding machines, conveyed upwards and then ground. The resulting regrind is mixed with virgin material and returned to production. ♻️
We reuse 100% of the regrind we generate. This allows us to use material already in our process to manufacture further components.
The proportion of regrind added varies depending on the component, applicable requirements and customer specifications. We adjust this proportion to meet customer requirements while ensuring that all specified product properties, relevant regulations and customer specifications are maintained.
