Our Quality Promise: Precision in Every Die-Cast Component
AMZ Weissenseer Präzisionsguss GmbH stands for reproducible quality in aluminium and zinc die casting. Our quality management accompanies every project – from component development and tool design through in-process inspection to final inspection. This is how we ensure that castings, assemblies and machined components reliably meet the agreed customer specifications.
Quality and customer satisfaction
At AMZ Weissenseer Präzisionsguss, quality does not begin at final inspection – it starts with supporting the development of the customer-designed component, the design of the die-casting tool and the definition of the inspection strategy. Our goal is a stable, traceable and cost-effective manufacturing process – from the first sample part to series delivery.
Our in-process quality assurance uses state-of-the-art testing equipment and documented inspection procedures to detect deviations early, adjust processes in a targeted manner and reliably keep components within customer specifications.
In doing so, we combine decades of die-casting experience with precise metrology, non-destructive testing, material analysis and traceable documentation. Technical buyers, quality managers and development departments thus receive a reliable basis for supplier qualification, series approval and long-term cooperation.

3D Coordinate Metrology with ZEISS CONTURA G2
For the precise dimensional inspection of complex die-cast parts, AMZ uses a ZEISS CONTURA G2 700 aktiv with VAST-XT scanning sensor and ZEISS CALYPSO measuring software. 3D coordinate metrology supports initial sample inspections, in-process measurements and customer-specific inspection reports. Especially with tight tolerances, complex geometries and function-critical component areas, tactile measurement provides a reliable basis for process and component approvals.
Non-Destructive Testing: Industrial X-Ray Inspection
Using the BOSELLO SRE MAX 70-120 160/225 kV X-ray system, AMZ performs non-destructive testing of die-cast parts to assess internal quality characteristics. X-ray inspection is particularly suited to evaluating shrinkage cavities, porosity, inclusions and microstructure – without damaging the component. This makes it a key element of quality assurance for safety-, function- or leak-tightness-critical castings.
Spectral Analysis for Material Testing of Aluminium and Zinc
Spectral analysis with the AMETEK SPECTROMAXx is used to verify alloy composition. This ensures that aluminium and zinc alloys meet the defined material requirements. Material analysis is particularly relevant when components must fulfil mechanical, thermal or surface-related requirements.
Leak Testing, Surface Roughness and Coating Thickness Measurement
Depending on the drawing, function and customer specification, AMZ complements dimensional and material testing with leak tests as well as surface roughness and coating thickness measurements. This allows function-relevant features to be inspected – such as sealing surfaces, machined surfaces and areas with defined coating thickness – particularly for ready-to-install die-cast components and assemblies.
Mechanical Testing with ZwickRoell Z010 RetroLine
The ZwickRoell Z010 RetroLine tensile/compression testing machine with testXpert3 software enables mechanical testing of materials, specimens or component-related features. Software-based evaluation delivers traceable test results and complements our geometric, non-destructive and material-analytical quality assurance.
Certified Processes: DIN EN ISO 9001:2015 & AIRBUS Audit
AMZ Weissenseer Präzisionsguss GmbH has been certified to DIN EN ISO 9001 by TÜV Rheinland Cert GmbH since 26 November 2009. Our current certification to DIN EN ISO 9001:2015 confirms our quality management system under certificate registration no. 01 100 6011.
The certified scope covers process development, production and sales of ready-to-install components and complete assemblies manufactured by die casting in aluminium and zinc. Our quality management is therefore not limited to individual inspections, but is integrated across the entire value chain.
You can find out more about our manufacturing focus on the pages Aluminium Die Casting, Zinc Die Casting and Industries / Customers.
From 26 November 2009 to 23 November 2023, AMZ was additionally certified to IATF 16949:2016. Due to the considerable economic effort required for the formal implementation of the IATF standard, AMZ now focuses on certification to DIN EN ISO 9001:2015.
The quality standards and process-oriented working methods introduced under IATF 16949 remain an integral part of our approach to quality.
Our Quality Management System: From Goods Receipt to Shipping
Our quality management system covers the entire production process. This includes:
- Incoming inspection of materials and purchased parts
- Verification and approval of relevant material and process data
- Process monitoring during die-casting production
- Initial sample inspection and in-process dimensional inspection
- X-ray inspection, spectral analysis and mechanical testing as required
- Final inspection of ready-to-install components and assemblies
- Documentation of test results according to customer and project requirements
- Traceability through defined markings and process data
This turns certification into an operational quality process: measurable, documented and geared to the requirements of industrial customers.
Quality Metrics and Continuous Improvement
AMZ manages quality and delivery performance using key metrics such as external complaint rate, internal scrap rate, on-time delivery (OTD) and First Pass Yield (FPY). Since PPM figures fluctuate significantly for small and medium production runs, we additionally evaluate performance – depending on lot size and customer requirements – using percentage-based metrics and rolling time periods.
Our current figures and targets:
- External complaint rate: approx. 1% of goods delivered (target: < 3%)
- Internal scrap rate: < 0.5% of production volume
- On-time delivery: approx. 98% OTD
- First Pass Yield: > 95% (depending on component and inspection requirements)
These metrics feed into our continuous improvement process (CIP) for manufacturing, inspection and delivery processes and provide a solid basis for supplier evaluations and series production projects.
Reference Audit: Aerospace Quality Requirements
In an audit conducted by our customer AIRBUS in 2007, AMZ WPG was certified as successfully operating a comprehensive quality management system for aerospace industry suppliers in accordance with DIN EN 9100.
This audit is a particularly strong signal of trust for us: the aerospace industry places exacting demands on process reliability, documentation, traceability and supplier quality. The successful audit underlines that AMZ is able to meet even the most demanding industrial quality requirements in a structured manner.
