Micro Injection Moulding Companies

What is Micro Injection Moulding?

Micro injection moulding is a specialised moulding process used to manufacture small and intricate products weighing less than a few grams, with tolerances in the range of 10 to 100 microns. The process uses specialised micro injection moulding machines with precise shot control, advanced heating systems, and ultra-precise clamping mechanisms to handle the unique challenges of manufacturing these miniaturised components.

These ultra-precise components require exceptional control in temperature management, material handling, and mould design to achieve consistent quality at such demanding tolerance levels. Micro moulding combines traditional injection moulding principles with advanced micro-manufacturing techniques to produce parts for medical devices, electronics, and precision instruments where dimensional accuracy is critical.

Benefits of Micro Injection Moulding

Micro injection moulding offers several key advantages for ultra-precise, miniaturised plastic components, including:

• Exceptional Dimensional Accuracy - Micro injection moulding can achieve tolerances as tight as ±0.005mm on critical dimensions, with surface finishes measured in nanometers. This precision is essential for miniaturised components where even microscopic variations can affect functionality.
• Consistent Micro-Scale Repeatability - Advanced process control systems ensure part-to-part consistency at the micro level, critical for applications where components must fit and function reliably in miniaturised assemblies and devices.
• Complex Micro Geometries - Intricate features such as micro channels, tiny bosses, thin-walled structures, and precision-moulded threads can be produced with exceptional accuracy, enabling sophisticated functionality in compact designs.
• High-Volume Production Capability - Once optimised, micro injection moulding can produce thousands of tiny components per hour with consistent quality, making it economical for high-volume medical device and electronics applications.
• Material Versatility at Micro Scale - Wide range of materials can be processed including engineering plastics, biocompatible polymers, and speciality compounds, each requiring specific optimisation for micro-scale processing.
• Integrated Micro Assembly - Multiple micro features can be moulded simultaneously, reducing the need for secondary assembly operations that would be extremely difficult at such small scales.

Applications of Micro Injection Moulding

Micro injection moulding serves industries requiring ultra-precise, miniaturised components with exceptional quality and functionality, including:

• Medical Devices - Micro catheters, drug delivery components, surgical instruments, diagnostic devices, and implantable components requiring biocompatibility and precision at the cellular level.
• Electronics and Telecommunications - Connector components, micro switches, fibre optic parts, sensor housings, and precision electronic components where miniaturisation and electrical performance are critical.
• Automotive Electronics - Micro sensors, precision connectors, electronic control components, and miniaturised parts for advanced driver assistance systems and vehicle electronics.
• Optical and Photonics - Micro lenses, optical components, laser device parts, and precision optical assemblies requiring exceptional surface quality and dimensional accuracy for light transmission applications.
• Laboratory and Analytical - Microfluidic devices, lab-on-chip components, analytical instrument parts, and precision laboratory equipment requiring accuracy at the microscopic level.
• Aerospace and Defence - Miniaturised components for avionics, precision instruments, sensor systems, and electronic warfare equipment requiring reliability in extreme conditions.
