Future of safety

PHASA have produced many machines over the last 25 years to process various safety critical parts, and have recently worked with 2 European Automotive manufactures on assemblies for the new Volvo XC90. Phasa supplied a 40/80 machine to Estonia to assemble PC/ABS Seat backboards with polypropylene map pockets and a 20/80 machine to C&C Plast, Czech Republic for PA6GF Plastic roof components.

The new Volvo XC90


The Volvo XC90 is the first car to be built on the new SPA system, it is a glimpse of the future of Volvo. SPA, standing for Scalable Product Architecture, is set to be moving us towards a ‘crash free future’ with a superior strength safety cage.

This SPA architecture also includes ground breaking electrical architecture, making the car more intelligent by operating as a single system where 4 masters, vehicle dynamics, safety, car body and infotainment, can control everything within the car meaning as they all communicate they can respond to the specific situation of the driver, whether that’s sitting in traffic and using the autonomous steering feature while the driver is able to interact with the ‘infotainment’ system or the sensors and detectors seeing a pedestrian or large animal and activating the auto brake features of the car.

SPA also allows for far more flexibility inside the car. The new XC90 features innovatively designed seats that free up interior space for passengers in the second and third rows, helping make the new XC90 a genuine seven-seater.

Being the first car built on SPA and with the emphasis on safety it is really important that every element of the car is as safe and secure as it possibly can be, that’s why they have trusted PHASA equipment to assemble the selected parts of the new car. The PHASA process offers a tight and secure assembly that won’t become loose over time or in extreme conditions of temperature or vibration.

The strength of the plastic stakes joining the parts must not be weakened when they are processed, this happens with other contact processes where reforming creates stress which is released over time making the fixture less secure. 

This isn’t the case with the PHASA process, using non-contact hot air to precisely heat the stake, followed by a cold former tool which clamps the heated stake under pressure as the stake cools it contracts further actually pulling the assembly tighter together. And as the process is essentially a re-moulding of the original plastic there is no stress or memory within the new form, meaning it stays tight and secure eliminating any loosening over time or squeak and rattle making it the perfect choice where safety is priority.
