At KT, we combine rapid tooling with injection molding to deliver production-quality plastic parts in a fraction of the time and cost of traditional hard tooling. For this device housing project, we used our shared mold base system and CNC-machined inserts to create a functional mold, enabling hundreds of molding cycles. Our DFM optimization ensures parts like this housing have minimal warpage, consistent wall thickness, and reliable assembly features.
🛠️ Production Workflow
- DFM Analysis & Mold Design: Our engineers analyze the housing design to optimize wall thickness, draft angles, and rib placement, ensuring moldability and reducing risks like sink marks or warpage. We design the mold to include ejection features and runners tailored to the part’s complex structure.
- Rapid Tooling Fabrication: Using high-speed CNC machining, we create precision steel mold inserts for the housing. Combined with our shared mold base system, this cuts tooling lead time and cost by 30–50% compared to conventional hard tooling.
- ABS Injection Molding: Black ABS material is melted and injected into the mold under controlled temperature and pressure. The process is optimized to maintain consistent part quality across the housing’s ribs, bosses, and large cutouts.
- Post-Molding Finishing: Parts are trimmed, degated, and cleaned. All surfaces are inspected for burrs, warpage, or cosmetic defects to ensure they meet fit and finish requirements.
- Fit & Function Validation: The housing is assembled with internal components (circuit boards, displays, fasteners) to verify screw boss alignment, snap-fit functionality, and overall dimensional accuracy.
