Quality Control
Quality control stands at the core of every successful mica fabrication project. Manufacturers implement strict inspection protocols to detect and address defects before parts reach customers. The table below outlines :
Defect | Description & Detection Method | Causes | Remedies & Prevention |
---|---|---|---|
Delamination | Surface layers peel or flake off; detected visually by surface flaking | Contamination, incompatible materials, excess release agents, moisture | Pre-dry materials, ensure clean resin, redesign mold, control release agents |
Discoloration | Color streaks or spots visible on surface; detected visually | Residual pellets, unstable colorants, uneven mixing | Clean equipment, use stable colorants, ensure uniform mixing |
Short Shot | Incomplete filling of mold cavities; detected by missing part sections | Blocked gates, low pressure, trapped air, cold mold, high viscosity | Redesign gates, increase pressure, raise mold temperature, improve venting |
Burn Marks | Dark or discolored spots; detected visually and by odor | Overheated air, poor venting | Clean mold, improve venting, adjust injection speed |
Splay | Silver or mica-like streaks on surface; visible visually | Excess moisture, overprocessing | Dry materials, optimize processing temperature and time |
Knit Lines | Seams where flow fronts meet; visible as weak lines or seams | Mold design, flow front meeting points | Relocate gates, improve venting, allow overflow at knit lines |
Sink Marks | Small depressions on surface, especially near ribs or bosses; visible visually | Thick projections, insufficient material injection | Redesign part thickness, add material carefully, use foaming or gas-assist molding |
Warping | Distortion of part shape; detected visually | Non-uniform cooling, filler shape | Adjust cooling, change filler type |
Marbling | Color inconsistency or streakiness; visible visually | Poor additive dispersion, undermixing | Increase mixing time, adjust screw speed and back pressure, reformulate colorants |
Advanced equipment, such as automated inspection systems and AI-driven quality control, further enhance precision and reduce waste. Manufacturers also use rapid prototyping to accelerate development and refine designs, ensuring high quality and reliability.
Tip: Mica’s , along with its resistance to heat, moisture, and chemicals, helps maintain the integrity of finished parts even in harsh environments.
