High-precision inspection of injection molded components
MABRI.VISION builds and develops high-quality machine vision solutions and modular inspection systems for your production processes. In the production of injection molded components, errors often occur that lead to defective components. Our modular inspection systems for plastic and injection molded parts reliably detect defective components and sort them out.
What do we inspect?
Incompletely filled molding
We use 2D and 3D inspections to determine the completeness of molded parts in critical areas, such as thin areas or points remote from the sprue. We offer inline-capable inspection solutions even for the smallest structures on precision molded parts.
Sink marks and demolding problems can negatively affect the appearance and function of molded parts. With high-precision surface inspection methods, our inspection systems detect the smallest form deviations in the process.
Depending on the process, burrs and webbing can occur during molding processes. In the case of multi-component processes in particular, these effects can interfere with the function. With our inspection systems, we record critical contours and can thus identify burr formation in the process at an early stage.
Shape inspection, dimensional accuracy
MABRI.VISION offers solutions for 100% inline component measurement of complex molded parts. In particular, components with pins for electronic contacting must be inspected for dimensional accuracy for automated assembly processes in terms of shape and position.
Even if the shapes are subject to little variance in injection molding processes, even the smallest changes can have a major effect on the function. With our inspection systems, we record structural parameters, such as channel widths for in-vitro diagnostics, in order to minimize variances in flow properties and volume.
A large number of factors, such as inclusions, diesel effect, dark points, weld lines and streaks, can have a direct influence on the functional elements of the molded parts. Depending on the inspection task, we record the surfaces and evaluate the data with classic and AI-based vision tools in order to detect the smallest defects.
If the dimensional accuracy of forms, functional surfaces or contact points in 3D space has to be checked, MABRI.VISION offers inspection systems with high-precision profile section sensors. Thanks to the short-wave blue laser, the measuring process achieves repeatability of up to 0.3 µm. Almost any material and surface texture can be inspected in this way.
Silicone has many applications in medical technology due to its material properties: highly flexible, long service life and biologically well-tolerated. This poses many challenges for manufacturing technology. With our computer vision system we check silicone components for micro defects, shape and inclusions.
2D code, data matrix
A large number of 2D codes, e.g. Capturing data matrix codes at different working distances can be challenging for classic readers. MABRI.VISION has developed a platform for 2D codes (QR code, data matrix code) that is optimized for throughput and reading rate.
If downstream production processes or product quality are dependent on the cavity, the cavity number must be recorded at crucial points. MABRI.VISION offers vision solutions that can reliably record the cavity number through smart lighting concepts and deep learning.
Our solutions for the inspection of injection molded components
MABRI.VISION has specialized in the development and implementation of complete vision solutions for use in production and research. Whether 100% inspections directly on the goods carrier system or in the clean room: by combining different high-performance optics, we meet your individual inspection requirements.
Inspection on the goods carrier system
Combination of 2D and 3D inspections for a comprehensive 100% inline component measurement on the goods carrier.
Inline high-speed microscopy
Our high-speed microscopy platform enables the smallest injection-molded structures to be inspected in the process cycle.
Computer vision 2D / 3D
Are you looking for a solution that should be integrated into your process? We offer a wide range of vision solutions.
Testing on the rotary clock
Our rotary clock inspection system enables a large number of inspections in the smallest of spaces, with manual or automatic assembly.
Applications and implementations for injection molded parts
Microstructures in vitro diagnostics
On injection-molded components for in-vitro diagnostics (digital PCR), we use our high-speed microscope to inspect duct closures, duct structures, patency, filling points, defects, particle entry and evenness at up to 1 million inspection points per component.
Plug connections and contacts
In the process (high speed) we inspect connector housings for possible defects with telecentric matrix cameras. Furthermore, we record the presence, wobble and the position of contacts in time. For products with variants, we inspect the coding and locking devices.
3D component testing | Medical technology
With high-precision profile section sensors, we record the 3D shape of medical components in the process and check for micro-defects and the smallest form deviations.
Micro defects in silicone sealing rings
The sealing properties of silicone rings can be impaired by defects and process-related errors such as burr formation. With a combination of 3D profile cutting and camera technology, we check silicone rings for micro-defects and dimensional accuracy in the process.
Registration of cavity numbers
Due to the tool or the material, the cavity numbers can be very weak and therefore difficult to read. With optimized lighting and AI, our vision system reliably reads the number of cavities in the process, even with the slightest contrast differences.
