Frequently asked questions
What is STÅLFE’s relationship with Aquagroup?
Aqua Group is STÅLFE’s Approved Manufacturing Partner. STÅLFE provides the European commercial operations, technical project management, quality validation and international logistics coordination with Aqua Group foundries from RFQ to plant-gate delivery.
Does STÅLFE manufacture the castings?
Castings and precision machining are executed across partner foundry facilities. STÅLFE manages the industrial supply chain, commercial operations, engineering compliance and delivery to European clients.
Which materials can be sourced?
Grey and ductile iron, SiMo/Ni-Resist, carbon/alloy/stainless steel castings, plus non-ferrous brass, bronze, NAB and related alloys—subject to drawing and process fit.
What certifications support EU and automotive buyers?
Partner systems include ISO 9001, ISO 14001, ISO 45001, IATF 16949, PED and IRS (marine) as cited in partner materials. Project-specific certificates are confirmed per RFQ.
Can European buyers audit the foundry?
Plant visits and audits can be arranged through STÅLFE as part of qualification or serial-supply programmes.
How do lead times work?
Lead time depends on tooling status, alloy, machining scope and inspection depth. STÅLFE provides a programme plan after drawing review rather than a one-size quote clock.
How do I get the capability pack?
Request the authorized capability pack via the quote form with partner=aquagroup. Full presentation PDFs are shared with qualified European buyers on request—not published as open downloads.
Is Aquagroup only a pump company?
Aqua Group is known for pumps, but operates a multi-foundry casting division (iron, steel, non-ferrous) with captive machining—the scope STÅLFE coordinates for industrial component supply.
