At QCI Hills Laser Marking, precision isn’t just a metric—it’s the core of everything we do. For over four decades, our team has partnered with leading manufacturers, engineers, and procurement managers across the aerospace, defense, medical, industrial, and commercial sectors to deliver flawless part identification and custom product branding.
Whether you need permanent barcode traceability on a critical aerospace component or high-contrast graphics silk-screened onto custom enclosures, accurate identification is essential for quality assurance, compliance, and product longevity.
We created this blog as a resource for engineers, project managers, and buyers navigating the complexities of part marking, surface finishes, and military/aerospace compliance.
40+ Years of Craftsmanship & Technology
Since our founding, manufacturing technology has evolved drastically, and so have we. By combining traditional craftsmanship with modern laser technologies, we’ve built a reputation for handling complex geometry, strict tolerances, and diverse materials with unmatched reliability.
Our full suite of specialized identification services includes:
- Laser Marking & Engraving: Ideal for permanent, high-precision surface marking without compromising structural integrity. Perfect for serial numbers, 2D Data Matrix codes, logos, and fine text.
- Silk Screening: Designed for sharp, vibrant, high-contrast text and artwork across large or irregular surface areas using custom artwork or blueprints.
- Ink Stamping & Direct Part Marking (DPM): Versatile, cost-effective marking solutions for both standard and specialized industrial applications.
Marking Across Any Substrate
No two projects are identical, and choosing the right marking process depends heavily on your material. Over the past 40+ years, we have refined our processes to handle a wide range of substrates, including:
- Metals: Stainless steel, titanium, aluminum (raw or anodized), brass, copper, and specialized alloys.
- Plastics & Synthetics: ABS, polycarbonate, acrylic, Delrin, and high-density polymers.
- Specialty Materials: Ceramics, glass, coated surfaces, and wood.
Built for Strict Quality & Compliance
In critical industries like defense and aerospace, a part mark isn’t just visual—it’s a matter of regulatory compliance. Our internal quality control system is structured to ensure every part leaving our shop meets your exact engineering blueprints and industry specifications, including MIL-STD-130 and AS478 standards.
Every job undergoes rigorous inspection to verify:
- Legibility & Contrast: Crisp lines, clear barcodes, and readable text under standard inspection conditions.
- Dimensional Accuracy: Exact placement verified against your technical drawings.
- Durability: Resistant to wear, environmental exposure, and severe operating conditions.
