PHILOSOPHY INJECTION MOULDING
INDUSTRIAL PIPING SYSTEM
PHILOSOPHY INJECTION MOULDING CENTRAL INJECTION MOULDING GATE
High dimensional accurancy of the fitting
No joint lines (source of weakness!)
Low internal stresses
Same flow distance for all flow paths
High long time properties (internal pressure test):
- Requirements for the standards: 165h
- AGRU fittings reach more than 1.500h upto 10.000h higher safety
