Engineered for smart watch OEM/ODM manufacturers, wearable tech brands, and custom wearable accessory suppliers, our custom smart watch case molds are precision-machined to 1:1 match your 2D/3D drawings (CAD, STEP, IGES, DXF). Tailored for all mainstream smart watch types—square/round/rectangular cases, sports waterproof models, and luxury slim designs—they excel at producing thin-wall structures (1.0–2.5mm thickness, common in smart watches) with ±0.005mm tolerance, and deliver 12–15 day tooling to keep up with wearable tech’s fast product 迭代 (iteration) cycles.
Smart watch case production has unique pain points that generic molds can’t resolve—our design directly targets these to protect your product functionality and market timelines:
- Thin-Wall Deformation Ruins Fit: Smart watch cases rely on 1.0–2.5mm thin walls for lightweight wear, but standard molds cause 15%+ deformation (e.g., warped edges, uneven thickness) during injection—leading to cases that don’t fit watch cores (screens, batteries) or seal poorly;
- Micro-Structure Precision Gaps: Cases need tiny, aligned features (e.g., 0.8mm-thick side buttons, 1.2mm sensor cutouts, magnetic charging port grooves). Even 0.01mm deviation breaks functionality (e.g., buttons stuck, sensors blocked);
- Slow Tooling Misses Wearable Cycles: Wearable tech launches every 3–6 months—industry-average 20+ day tooling delays mean missing seasonal windows (e.g., holiday gift peaks) or falling behind competitors.
Heya solves these with thin-wall compatibility, ±0.005mm precision, and 12–15 day tooling—turning “wearable production hurdles” into “on-time, high-fit smart watch cases.”
We tailor every mold to your smart watch’s unique design and thin-wall needs, focusing on details that define wearable usability:
Our molds are engineered to balance thin-wall performance and speed, with specs that directly impact your production efficiency:

Our entire smart watch case mold production process—from drawing review, material selection, and thin-wall-focused machining to final precision inspection—strictly complies with ISO 9001:2015 standards. This ensures:
- Consistent Thin-Wall Precision: Every mold undergoes Zeiss CMM testing (±0.0005mm accuracy) to verify ±0.005mm tolerance and uniform wall thickness;
- Traceable Processes: Full records (material certificates, machining logs, thin-wall deformation test data) are provided for your supply chain audits;
- Reliable Problem-Solving: Clear protocols for adjusting thin-wall cooling or micro-feature alignment—no delays if minor tweaks are needed.
Note: We hold ISO 9001 certification—to keep our focus on delivering cost-effective, wearable-friendly molds for smart watch brands.
- Smart Watch OEM/ODM Manufacturers: For high-volume production of standard smart watch lines (e.g., 50k+ cases/month) where thin-wall compatibility and fast tooling cut long-term costs;
- Wearable Tech Brands: For launching custom smart watches (e.g., luxury designer models, rugged outdoor watches) where 3D drawing support ensures unique shapes (e.g., curved edges) are replicated perfectly;
- Custom Accessory Suppliers: For niche smart watch cases (e.g., eco-friendly resin, limited-edition designs) where ±0.005mm precision ensures compatibility with original watch cores.
