Medical plastics deliver a pharmaceutical compound to its target site. Therefore, they’re vital to human health in everyday life and must guarantee functionality and achieve their desired therapeutic effect. In ensuring proper production and complying with a variety of industry norms, you have to perform quality control on large volumes, process small features and non-standard geometries, and correctly handle plastics that may be transparent, sensitive, or prone to bending.
Also known as medical combination products, medical plastics either comprise multiple components, combine multiple products, or may only be used together with a specific separate drug or device. ZEISS therefore helps you run fast checks on multiple components simultaneously, undertake multisensory inspections of flexible and soft parts, and perform freeform analysis to achieve optimum function and design of assemblies.
For basic plastic components such as the housing of an inhaler the challenge is particularly to ensure the quality of large production runs and GD&T.
The challenge with multiple plastic pieces as assembly is to capture small features of freeform parts. In most cases, the parts must be within tight tolerances to ensure the mechanical function while being produced in large batches. For example, syringes, insulin pens or various flow control (single use) parts are assembled from different plastic components.
Self-infusion pumps, blood tests, and asthma inhalers with display are examples for complex plastic pieces with electronic components. These products often have sensitive surfaces and consist of thin bending or transparent plastics. Furthermore, there is also the challenge of a fast check with multiple components and materials.
Tool manufacturing should involve as few iteration loops as possible while ensuring accuracy and minimizing waste. Beginning with PMI-based inspection plans and extending through to the comparison of CAD models, this workflow has to ensure flawless handling of external influences such as electrodes.
By promoting much faster and more cost-effective correction of high-precision tools, ZEISS solutions enable you to optimize your operations accordingly.
- Creation and implementation of inspection plans must be made less costly and time-consuming
- Avoid potential errors and lost time caused by transferring dimensions from the drawing to the inspection software via manual copying
- PMI-Based Inspection Plans - Transfer PMI characteristics from CAD software to inspection software
- Import and export of a wide range of data formats
- Eroding, manual alignment of electrodes, and performing measurements directly on the EDM machine
- Electrode Inspection on CMM and 3D scanning systems
- Profit from shorter machine setup times, higher accuracy and much higher productivity
- Tool correction process was previously known for being time-consuming, unreliable, and heavily dependent on expertise of individual user. Corrections then required multiple iterations
- Ensure alignment of mold halves to reduce flashing
- CAD Model Comparison with ZEISS REVERSE ENGINEERING
- Tool correction process with fewer iterations saves time, boosts efficiency, and lends a competitive edge
The structure of the manufacturing process enables highly efficient production of plastic components in large batches. Part design and requirements may vary considerably, however, with rotation capacity, elasticity, and compatibility with materials such as metal just some of the potential factors.
It is of course essential to assess the raw material properties at the start of the process, both to detect impurities and to safeguard the desired product performance. And through the use of ultra-modern machines and systems based on optical technologies and computed tomography, it is now possible for very small parts featuring complex geometries to be manufactured with great precision – and evaluated via non-destructive checks.
- Perform quick and easy imaging and analysis of stock before production begins for more reliable products
- Impurity Detection and Classification - correlative workflow for light microscopes and scanning electron microscopes
- Images can be captured in ZEISS ZEN core, which features a GxP module to establish an auditable trail for each product or batch
- A final check has to be performed on produced parts to ensure accuracy of dimensions and tolerances so that individual components fit together seamlessly in the assembly
- As the surface of plastic components is particularly sensitive to tactile measurement, optical solutions and CT solutions are preferred for this purpose
- Create a fullfield 3D scan of your part for inspection or even scan multiple parts at the same time
- X-ray technology for volume visualization and inspection of internal defects
- Detect particle contamination in line with the exacting standards of the medical industry
- Minimize maintenance costs via swift measurement and analysis of critical particles
- ZEISS Technical Cleanliness Analysis is a solution for light microscopes that ensures important settings are always correct and supports automatic image analysis in ZEISS ZEN core
- Correlative Automated Parts Analysis represents an extension of Technical Cleanliness Analysis by combining your data from both light and electron microscopes in a single workflow. This approach enables you to characterize process-critical particles and identify contaminating particles in next to no time
- Non-destructive checks have to be performed on aspects such as mating surface contact, adhesion of components, and internal surfaces
- Various computed tomography (CT) hardware options including ZEISS METROTOM and ZEISS VoluMax enable you to see inside parts, even down to the powder or medication packaged within a given device.
- Their non-destructive approach is quick and holistic, making it possible to perform full-scale inspections and pinpoint any potential errors.
