•Complex geometries with undercuts and thin walls
•Insert molding and overmolding techniques
•Surface texturing and specialized finishes
•Color matching to precise specifications
Whether you need prototypes, small production runs, or high-volume manufacturing, our flexible production system scales to meet your specific requirements.
Mold Design
Our engineering team creates optimized mold designs using advanced CAD/CAM systems with mold flow analysis to prevent defects before production begins.

Quality Control
Comprehensive inspection protocols including dimensional verification, material testing, and functional validation ensure defect-free components
Tooling Development
In-house mold fabrication with precision CNC machining ensures tight tolerances and excellent surface finishes for your custom components.

Production
State-of-the-art injection molding machines with capacities ranging from micro-components to large parts, capable of handling high-volume production runs.
1
Design for Manufacturability (DFM) Analysis
Our engineering team reviews your designs to identify potential manufacturing challenges before production begins. We provide detailed recommendations for geometry modifications, material selection, and processing parameters to optimize quality while reducing costs.
2
Mold Flow Analysis
Advanced simulation software predicts material flow patterns, cooling rates, and potential defects, allowing us to optimize mold designs for consistent part quality and reduced cycle times.
3
Prototyping and Validation
Rapid prototyping capabilities enable quick iteration and functional testing before committing to full production tooling, reducing development risks and accelerating your time to market.
1
Polypropylene (PP)
Ideal for plastic caps and automotive interior components requiring chemical resistance and durability. PP offers excellent fatigue resistance and maintains structural integrity through repeated use cycles.
2
Delrin/POM
High-performance engineering plastic for precision bushings and rollers. Provides outstanding dimensional stability, low friction coefficient, and excellent machining characteristics.
3
Nylon (PA)
Superior strength-to-weight ratio for wheels, rollers, gears, and bushings. Nylon components offer exceptional wear resistance and self-lubricating properties, making them perfect for mechanical applications.
4
ABS
Versatile thermoplastic for housing components and enclosures. Offers good impact resistance, aesthetic surface finish, and excellent electrical properties for electronic applications.
Quality Assurance Systems
Quality is built into every step of our manufacturing process, from material seletion to final inspection. Our comprehensive qualtiy management system includes:
•Statistical Process Control (SPC) for real-time productioin monitoring
•Coordinate Measuring Machine (CMM) verification of critical dimensions
•Material certification and traceability documentation
•First Artical Inspection Reports (FAIR) for new production runs
•In-process and final quality checks with detailed inspection reports

SIGMA Hardware Taiwan quality assurance team utilizes precision measurement equipment to verify that all components meet exact specifications before shipment.
