Services
Medical Device Pad Printing
Specialized pad printing for medical devices in ISO Class 7 cleanroom environments. Utilizes Class VI biocompatible inks with USP testing documentation. Capable of printing on critical components like syringes, catheters, and diagnostic equipment with tolerances to 0.025 inches. Services include pretreatment (corona/flame), heat curing, and full regulatory compliance documentation.
Industrial Pad Printing
Precision decoration of industrial components including aerospace parts, electronic housings, and automotive assemblies. Handles complex geometries from 1mm resistor shells to 18-inch enclosures. Offers multi-color printing with racetrack/rotary systems and durable adhesion for harsh environments. Supports substrates like ABS, polycarbonate, metal, and glass with in-house tooling fabrication.
Screen Printing
High-resolution screen printing for flat, curved, or cylindrical surfaces requiring broad coverage. Utilizes vector-based imaging for exact registration on components like control panels and display bezels. Specializes in industrial applications needing thick ink deposits and UV-resistant formulations for long-term durability in outdoor environments.
Prototype Decorating
Rapid-turnaround decorating solutions for product development stages. Offers digital printing for design validation and small-batch production. Capable of executing complex color schemes and artwork iterations with 1-3 day lead times. Supports material testing and process validation for subsequent high-volume manufacturing.
Cleanroom Printing
Certified ISO Class 7 cleanroom operations for contamination-sensitive applications. Features HEPA-filtered air circulation and dedicated workflow protocols. Ideal for implantable device components, surgical instruments, and pharmaceutical equipment requiring particulate-free surface decoration and validated process controls.
Questions
What medical device printing certifications do you hold?
We maintain ISO 9001:2015 certification and operate an ISO Class 7 cleanroom. All medical-grade inks meet USP Class VI biocompatibility standards with full documentation available.
Can you print on complex surface geometries?
Yes, our silicone pad technology handles compound curves, recessed areas, and textures. We routinely print on parts with tolerances down to 0.025 inches and surfaces as small as 1x2mm.
What industrial substrates do you support?
We print on ABS, polycarbonate, polypropylene, nylon, Delrin, metals (including plated/anodized), glass, and ceramics. Specialized pretreatment processes ensure adhesion on challenging materials.
How do you ensure print durability?
We employ corona discharge, flame treatment, and heat curing methods to optimize ink adhesion. Printed parts undergo rigorous testing to ensure longevity exceeding product lifecycle requirements.
What quality control measures are in place?
Dual-level QC includes fixture fit verification for 100% part inspection and supervisor-led daily print quality audits. Production documentation and certificates of compliance are available upon request.
What are typical lead times?
Standard production runs take 14-21 days. Prototypes often complete within 3 business days. Expedited options available depending on machine capacity and required post-treatment processes.
