Heya Custom Electroformed Mold Cavities & Cores | CD Pattern Keyboard Switches
With over 15 years of expertise in precision electroforming, Heya specializes in custom electroformed mold cavities, cores, and CD pattern keyboard switches—serving industries including automotive, consumer electronics, medical devices, and home appliances. Our products combine micron-level precision, durable performance, and aesthetic appeal, trusted by clients such as electronics manufacturers and mold makers.
Our electroformed mold cavities and cores are meticulously engineered to deliver unparalleled precision and durability—critical for high-quality injection-molded parts:
-
Micron-Level Precision: Using advanced electroforming technology, we achieve dimensional tolerance of ±0.005mm and surface roughness of Ra ≤0.01μm. This ensures injection-molded components perfectly replicate intricate details, such as fine textures, small holes, and complex curves—vital for products like medical device components and electronic connectors.
-
Superior Material Performance: High-purity nickel and nickel-cobalt alloys offer exceptional wear resistance, enabling mold cavities and cores to withstand ≥500,000 injection cycles without significant wear. They also maintain stability during continuous operation at 180°C, making them suitable for high-temperature injection molding of engineering plastics like PEEK and LCP.
-
Customization for Diverse Molds: We provide fully tailored solutions based on client drawings (CAD/STEP files), including various sizes (5mm to 500mm), shapes (irregular, curved, stepped), and surface treatments (polished, textured). Whether for small precision molds or large automotive molds, we meet specific requirements.
Our CD pattern keyboard switches stand out for their unique visual appeal and reliable performance, making them ideal for enhancing product usability and brand image:
-
Exquisite CD Patterns: CD patterns feature precise line spacing of 0.1-0.5mm, created via advanced electroforming and machining processes. These patterns not only add a premium metallic aesthetic to keyboards but also improve grip, preventing slippage during operation.
-
Durable & Responsive: Keyboard switches are made from high-quality materials such as PMMA, PC, and electroformed nickel-plated ABS, boasting a long lifecycle of ≥1,000,000 presses. They offer excellent key travel consistency (tolerance ±0.02mm), ensuring a smooth and responsive user experience.
-
Weather & UV Resistant: Switch surfaces undergo special coating treatment for weather resistance and UV protection. They retain color and performance, with no yellowing even after 5,000 hours of sun exposure—suitable for indoor and outdoor applications like automotive dashboards and outdoor control panels.
-
Comprehensive Customization Support: From design optimization to prototyping and mass production, we offer one-stop customization services. Our engineering team provides DFM (Design for Manufacturability) analysis to ensure products are suitable for electroforming and meet required performance standards.
-
Rapid Turnaround: We understand the importance of time-to-market. For custom mold cavities and cores, prototypes can be delivered in 7-10 business days, with mass production in 20-30 days. For CD pattern keyboard switches, sample production takes 5-7 business days, with mass production in 15-25 days.
-
Strict Quality Control: Certified to ISO 9001 and IATF 16949, we implement rigorous quality inspection processes. Every product undergoes 100% dimensional testing (using 3D measuring machines with ±0.001mm accuracy) and performance testing to meet client specifications and industry standards.


Heya is committed to delivering high-precision, custom electroformed products to meet diverse client needs. Whether you require mold cavities and cores for injection molding or CD pattern keyboard switches for electronic devices, we have the expertise and capabilities to provide reliable, high-quality solutions.
