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
