At Yude Technology, manufacturing engineering bridges complex design intent and zero-defect mass production. We combine high-speed CNC mold making, automated LSR metering units, cleanroom processing, and SPC quality controls to deliver repeatable, high-tolerance components for medical, automotive, and high-tech industries.
Our multidisciplinary team of tooling designers, process engineers, and quality specialists ensures seamless scale-up from single-cavity prototype molds to high-cavity automated production cells.
In-house CNC toolroom equipped with high-speed milling spindles (24,000 RPM), mirror EDM, and slow-wire EDM cutting.
Closed-loop 1:1 ratio dosing pumps feeding high-shear liquid silicone rubber into temperature-isolated hot mold cavities.
Controlled cleanroom manufacturing environment for medical-grade devices, infant care products, and optical silicone lenses.
Specialized secondary operations to achieve pristine surface finishes and functional bonding characteristics.
Multi-shot injection techniques combining rigid engineering thermoplastics (PC, PA66, PBT) with soft elastomeric silicone.
Rigorous Statistical Process Control integrated into production lines to ensure zero defect delivery.
Key technical parameters and capabilities governing our precision mold making and injection molding operations.

Yude Technology operates under strict Quality Management System (QMS) protocols. From raw silicone material batch testing (rheometer viscosity & durometer hardness) to final packaging audit, every production lot is fully traceable back to raw material lot numbers and machine operating parameters.
Providing complete contract manufacturing solutions from molded component fabrication to retail-ready assembly.
High-precision fiber laser etching for permanent serial numbers, QR codes, company logos, and alignment indicators on silicone and plastic surfaces.
Automated multi-color screen and pad printing using medical-grade, abrasion-resistant silicone inks cured under infrared ovens.
Joining rigid plastic enclosures housing silicone seals using high-frequency ultrasonic horns or thermal heat-staking heads.
Cleanroom pouch sealing, blister packaging, custom barcode labeling, and master carton assembly ready for global retail distribution.
A: LSR has extremely low viscosity during injection and can flash into gaps as small as 5 microns ($0.005\text{mm}$). We prevent flash through ultra-precise CNC toolmaking, mirror EDM, active cold-deck thermal isolation, optical shut-off alignment, and rigid mold base construction with high clamping pressure.
A: Cryogenic deflashing freezes molded silicone parts using liquid nitrogen to make microscopic parting line flash brittle. The parts are then tumbled in a high-speed blast wheel with non-abrasive polycarbonate media, cleanly shearing off the flash while preserving part geometry and surface finish.
A: We utilize Statistical Process Control (SPC) software linked to automated optical measurement systems and CMMs. Critical-to-quality dimensions (CTQs) are sampled at fixed intervals, maintaining a $C_{pk} \ge 1.33$ baseline to guarantee zero out-of-spec parts reach shipment.
A: Our facility operates under ISO 9001 (Quality Management System) and ISO 13485 (Medical Device Manufacturing) certifications. All food-contact and medical-grade products are molded inside ISO Class 7 cleanrooms using FDA 21 CFR 177.2600 and LFGB compliant materials.
