Korean Cycling Brand — Custom Housing for Wireless Bicycle Computer (CNC + Injection Molding)
Client Pain Points
- The client was launching their first bicycle computer product and lacked design-for-manufacturing experience, resulting in structural issues such as snap-fit interference, insufficient boss wall thickness, and button sticking.
- The housing required precise integration of two processes — CNC aluminum shell and injection-molded buttons — with a dimensional tolerance of ±0.05mm.
- Initial samples had assembly issues, delaying the overall development timeline.
- The client was concerned about potential mold failure costs and communication inefficiencies with the supplier.
MachMaster’s Solution
- Provided engineering support to optimize part design, including chamfers on aluminum parts, snap-fit tuning, and tightening tolerance zones.
- Adopted a hybrid manufacturing strategy: high-precision CNC machining for the aluminum body and injection molding for ABS buttons, all aligned with a unified assembly datum.
- Delivered CNC-milled prototypes within 5 days to validate fit and structure, while mold design was initiated in parallel.
- Assigned a dedicated project manager to oversee CNC, molding, and anodizing workflows — ensuring seamless communication and tight timeline control.
- Applied anodizing to the aluminum shell, with color variation controlled under ΔE < 1.5 for consistent aesthetics.
Final Results
- Functional prototypes delivered in 5 days; mold and mass production completed within 30 days.
- Assembly went smoothly; button feel and fit exceeded expectations — client called it “more professional than expected.”
- The client initiated two follow-up projects in the same product line and recommended MachMaster to their upstream bike brand partner.
- Established a complete cooperation loop from design optimization to production delivery, with plans for long-term strategic partnership.





American Pool Equipment Innovator — Hybrid Manufacturing for Leak-Proof ABS Seal Components
Client Pain Points
- O-ring groove surface at parting line caused micro-irregularities (<0.1mm), resulting in premature seal wear and >30% leakage
- Traditional solutions like metal machining were too expensive (+200% cost), while modifying the parting line would require full mold remanufacturing
- Client needed a reliable fix that didn’t break the budget or extend lead time
MachMaster’s Solution
- Re-engineered the mold to oversize the groove by +0.5mm, enabling precision CNC turning to fine-tune the sealing surface
- Applied CNC turning with ceramic tools at 3000 RPM, achieving Ra 0.8μm surface roughness
- Delivered 5 CNC-modified samples within 72 hours for real-world validation
- Implemented hybrid manufacturing: injection molding for body, CNC finishing for groove
Final Results
- Client verified 6-month continuous leak-free operation at 3m underwater
- Reduced per-unit cost by 39.5% and mold revision cost by 90%
- Client re-ordered 3 additional batches totaling 4,000 units
- Solution later applied in automotive, medical, and outdoor lighting products

Korean Electrical Enclosure Maker Resolves Riveting & Bending Conflict
Client Pain Points
- Stainless steel rivets couldn’t be pressed after bending
- Pressing them first blocked anodizing
- Design layout left no room for mechanical sequence adjustment
MachMaster’s Solution
- Switched to aluminum rivets (anodize-compatible)
- Rivets pre-installed before bending
- Problematic narrow sections redesigned and welded
- Ensured anodized surface integrity post-processing
Final Results
- Seamless fit and finish
- Avoided mold rebuild and reduced total cost
- approved for future batch orders
