BKT QA: Error minimization, process stability and permanent control.
Some call it a „continuous improvement process“ or „lean management“ or „six sigma method“... For us, it is simply common sense that tells us to produce as little waste as possible, to make work steps as efficient as possible and to ensure that we deliver consistent product quality
Our QA ensures the consistent production of consistently high-quality components. How? It takes all measures to minimize errors, ensures continuous process stability and constantly checks that the requirements for precision, functionality and aesthetics are met.
QA quick overview
- Separate QA room
- In-house measuring laboratory with Zeiss Inspect
- All common measuring equipment available
- Tactile and optical measurement “Keyence”
- Measurement control using coordinate measuring machines
- Color measurements
- Initial sample test reports
- Series-accompanying measurements: continuous monitoring of production parameters (temperature, pressure, cooling, injection speed, etc.)
- Surface inspection for burrs, sink marks, discoloration and scratches
- Load tests: testing mechanical properties such as tensile strength or tightness
- 3D scans possible
- Quality management according to DIN EN ISO 9001
Core quality assurance measures
- Incoming material inspections
For example, checking the plastic pellets for moisture, impurities or batch differences. - Process monitoring and control
For example, real-time monitoring of process parameters such as temperature (mold, melt), pressure, injection speed, cooling time, etc. using sensors. - Tool and machine maintenance
For example, regular cleaning and inspection of the molds for wear, contamination or damage as well as regular inspection of the clamping units and injection units. - Component testing
Dimensional checks using coordinate measuring machines and optical scanners. Surface inspection for burrs, sink marks, discoloration or scratches. Functional tests by checking mechanical properties such as tensile strength or tightness.
Extended QA measures
In addition to the core QA measures, we also carry out extended QA measures. These include the relentless root cause analysis of errors, including their correction, as well as documentation of production processes and ensuring traceability.
Error analysis and corrections
Binding, injection points, warping or incomplete filling are typical defects in plastic injection molding. With our ruthless root cause analysis, we do not look for the culprit, but rather for a solution to eliminate the defect.
Documentation and traceability
We log all process parameters as standard so that we can effectively determine when an error, defect or flaw has occurred and thus rectify the cause directly. Regular test results and batch information enable traceability.
