Benefits of Dimensional Testing in Plastic Injection Molding
A coordinate measuring machine (CMM) is a device that measures the physical geometric characteristics of an object, and in our manufacturing application—plastic parts. This device is commonly used in manufacturing processes to qualify or test a part against the design intent.
The machine can be operated manually by an operator or automated for computer control. Measurements are collected by a probe attached to the moving axis of the machine. By recording the coordinates of the object, points are generated and analyzed to construct a part’s features. These points are gathered and can be measured repeatedly to test identical parts, and then analyzed by technicians.
What are the benefits of CMM Dimensional Testing?
CMMs are unique technology that can save plastic injection molding customers valuable time to market and reduce costs. As parts grow more complex, the need for precise measurement and consistent results across all quantities of parts becomes essential. Using an injection molder that utilizes CMM dimensional testing capabilities will help deliver the results your company and products need. By verifying product quality, 3D inspections, tool certification, CAD comparison, reverse engineering, and dimensional analysis, CMM offers unparalleled assurance you can trust.
Other benefits of CMM dimensional testing include:
- Increased measurement efficiency by staging multiple parts, programming offline, and reducing part orientations
- Improved accuracy on challenging part geometries
- More data points on complex curves, surfaces, and profiles that are common in the industries PCI serves
Plastic Components Inc. uses the Hexagon 7.10.7 CMM dimensional testing machine. This machine features the most advanced metrology software and an intuitive graphical user interface that guides technicians through part programming and inspection.
The option for offline programming allows technicians to develop inspection routines while the machine is available for measuring. Geometry can be selected and parameters defined by reviewing the CAD model. Since data is automatically extracted from the CAD model, time is saved and costly errors are eliminated.
The key features of PCI’s CMM dimensional testing system are:
- Large work zone
- Motorized head
- Active scanning probe
- Automatic probe changeover
- Offline parametric 3D programming
Quality control in plastics manufacturing can present challenges. However, using CMM dimensional testing provides an innovative solution that guarantees highly repeatable results and dimensional reports for customers.
PCI has the most advanced technology and equipment, as well as the technical expertise and experience to successfully produce the highest quality plastic parts for your unique application.
