Open PDFOur ISO 9001:2015-certified system covers every phase, using automated tools and controlled environments to guarantee high-standard, production-ready products.
Incoming materials are inspected and fully traced throughout production; standardized, risk-based protocols guide every step, while automated equipment performs precise measurements and tests. Final verification includes full functional checks, and products are released only after meeting all acceptance criteria. When required, deliveries can be accompanied by a detailed certificate of conformity.
Every stencil, screen, and film is engineered, inspected, and documented to deliver repeatable performance and full audit-ready traceability.
Tight tolerances and controlled geometries for demanding SMT and industrial printing.
Achieve tolerances as tight as ±4 microns for fine-pitch SMT stencils and high-density industrial screens, validated against strict dimensional and geometric criteria.
Full visibility from raw material to final inspection.
Material batch control, process parameters, inspection data, and verification records every product can be shiped with a certified conformity report for complete, audit-ready traceability.
Checks at every critical step to minimize non-conformities.
Automated measurements, visual and microscopic checks, mesh tension analysis, pinhole detection, and functional tests ensure stable, repeatable performance over the full stencil or screen lifetime.
Innovation focused on print quality and lifetime.
Ongoing work on mesh technologies, emulsions, laser imaging, and materials to enhance print quality, extend stencil and screen life, and support next‑generation manufacturing requirements.
A consistent checklist applied to 100% of outgoing products.
Material traceability, dimensional and thickness verification, geometric and aperture accuracy, mesh tension and stability, optical density and resolution, registration and alignment, surface cleanliness and defect inspection, final conformity release, and ongoing process audits.
