Common Testing Instruments in Injection Molding
In the injection molding process, various testing instruments inspect and control molds, finished products, and raw materials to ensure product quality and production efficiency.
Dimensional and Geometric Measurement Equipment
1. Coordinate Measuring Machine (CMM)
Measures the three-dimensional dimensions, shapes, and positional accuracy to ensure alignment with design drawings.
Ideal for inspecting complex geometries and parts with high precision requirements.
2. Micrometers and Vernier Calipers
Used to measure the outer diameter, inner diameter, thickness, and length of parts.
Suitable for simple dimensional measurements.
3. Height Gauges
Measures the height, depth, and vertical distances of products.
Useful for inspecting planar dimensional accuracy.
4. Profile Projectors
Inspects product contours and shapes by magnifying fine features.
Suitable for evaluating curves and small components.
Surface Quality Testing Equipment
1. Optical Microscopes
Detects tiny defects, surface textures, and cracks in products.
Ideal for high-standard quality inspections.
2. Laser Scanners
Non-contact detection rapidly scans product surfaces to generate three-dimensional point cloud data.
Useful for analyzing surface characteristics.
Mechanical Performance Testing Equipment
1. Hardness Testers
Measures the surface hardness of products.
Common types include Rockwell hardness testers and Shore hardness testers.
Physical and Chemical Performance Testing Equipment
1. Melt Flow Rate Tester (MFR)
Measures the melt flow rate of injection molding materials.
Analyzes material flow properties and processing suitability.
2. Colorimeters
Detects whether the color of injection-molded products matches standard colors.
Used for color quality control.
Process Monitoring Equipment
1. Temperature and Humidity Sensors
Monitors injection molding environmental conditions in real-time.
Ensures stable processing conditions.
2. Online Dimensional Inspection Systems
Installed production lines to monitor dimensional deviations
Suitable for mass production.
3. Pressure and Flow Sensors
Detects injection pressure, mold cavity pressure, and flow state in injection molding machines.
Optimizes the production process.
