Engineered exclusively for mobile phone case OEM/ODM manufacturers, consumer electronics brands, and custom accessory suppliers, our custom mobile phone case injection molds are precision-machined to 1:1 match your 2D/3D drawings (CAD, STEP, IGES, DXF formats). Tailored for all mainstream phone case types—slim hard cases, shockproof soft cases, clear cases, and branded custom cases—they deliver ultra-tight ±0.005mm tolerance, use corrosion-resistant S136 steel, and ensure 10–12 day fast lead times to help you launch new phone case designs ahead of market competitors.
Mobile phone case production faces 3 critical pain points that generic molds can’t solve—our design directly addresses these to protect your product quality and time-to-market:
- Mismatched Drawings Cause Fit Issues: Off-the-shelf molds often deviate from custom case designs (e.g., camera cutout misalignment, button hole offset), leading to 15%+ scrap rates or phone cases that don’t fit device bodies;
- Slow Lead Times Miss Launch Windows: The consumer electronics cycle moves fast—delays of 20+ days (industry average) mean missing new phone release peaks, costing you market share;
- Weak Materials Shorten Mold Life: Standard steel molds wear out after 100k cycles, but phone case production needs 200k+ runs for popular models—forcing unplanned mold replacements and downtime.
Heya solves these by building molds exactly to your drawings with S136 steel and 10–12 day lead times—turning “production delays” into “on-time, high-quality case output.”
We tailor every mold to your phone case’s unique design and production needs, with a focus on details that matter for consumer appeal:

Our molds are engineered to meet the fast, precise demands of consumer electronics, with specs that directly impact your bottom line:
Our entire mold production process—from drawing review and material selection to machining, inspection, and delivery—is ISO 9001:2015 certified. This ensures:
- Strict adherence to your drawing specifications (no unauthorized deviations);
- Consistent quality across every mold (each undergoes dimensional testing with Zeiss CMM tools);
- Traceable production records (material certificates, inspection reports) for your supply chain audits;
- Clear processes for addressing any quality concerns (fast resolution to avoid production delays).

We only hold ISO 9001 certification—no other industry-specific certifications—to keep our focus on delivering reliable, cost-effective molds aligned with consumer electronics standards.
- Mobile Phone Case OEM/ODM Manufacturers: For high-volume production of branded or white-label cases, where S136 steel durability and fast lead times cut costs and meet retailer deadlines;
- Consumer Electronics Brands: For launching custom cases alongside new phone models (e.g., brand-logoed cases for flagship devices), where ±0.005mm precision ensures brand consistency;
- Custom Accessory Suppliers: For small-batch or niche cases (e.g., eco-friendly materials, limited-edition designs), where 1:1 drawing alignment brings unique concepts to life.
