QA & QC Process at Marcus Hi-Tech Engineering
At Marcus Hi-Tech Engineering, quality is engineered into every stage of our precision manufacturing process, rather than inspected in at the end.
Our dedicated Quality Assurance (QA) and Quality Control (QC) systems ensure every die-cast, machined, and assembled component meets the highest international standards of precision, durability, and compliance.
We follow globally recognized automotive and aerospace quality systems, integrating advanced inspection technologies and rigorous process validations to deliver zero-defect, high-performance components.
Solutions & Benefits
Quality Assurance (QA) – Preventive Systems
Our QA approach ensures that defects are prevented before production begins by:
- Design for Manufacturability (DFM): Early-stage optimization of part designs
- APQP (Advanced Product Quality Planning): Customer-approved process planning framework
- PPAP (Production Part Approval Process): Demonstrating product & process validation before start of mass production
- Prototyping & Trials: T0/T1 runs to validate tool performance & manufacturability
- Process Control Plans: Documented preventive systems for every manufacturing stage
Quality Control (QC) – Inspection & Testing
Our QC process verifies precision & consistency during production:
- In-line Inspection – Continuous monitoring by operators and machines during runs.
- CMM (Coordinate Measuring Machine) – High-accuracy dimensional inspection
- Optical Emission Spectrometer (OES) – Material chemistry validation
- Leak Testing Systems – Ensuring pressure-tight castings
- Air Plug Gauges & Receiving Gauges – Real-time component verification
- FAIR (First Article Inspection Reports) – Certification of initial parts meeting all specifications
- Sampling Inspections – Random checks during production to maintain ongoing compliance
Continuous Improvement Programs
- Kaizen & Lean Initiatives: Enhancing efficiency and reducing waste
- CAPA (Corrective and Preventive Action): Systematic resolution of root-cause issues
- Training & Skill Development: Regular team training on QA/QC tools and methodologies.
- Customer Feedback Integration: Closed-loop system for continuous improvement and manufacturing excellence
Why Marcus QA & QC Stand Out
Testimonial
"Marcus Hi-Tech's hot chamber capabilities allowed us to miniaturize our connectors without losing strength. The zinc castings are incredibly precise." —
David Chen
Product Architect, Consumer Electronics
"Speed was our priority. Their hot chamber machines pump out our lock housings faster than any supplier we've used before, and the tolerances hold up perfectly." —
Roberto Ricci
Supply Chain Director, Automotive Security
"We switched to magnesium hot chamber casting for our drone chassis parts. Marcus Hi-Tech delivered the weight savings we needed with zero porosity issues." —
Sarah Jenkins
Lead Engineer, UAV Systems
"The surface finish on our medical casings is mirror-like right out of the mold. It makes the plating process so much cheaper and easier." —
Dr. Alan Grant
Procurement Head, Surgical Devices
"For high-volume decorative hardware, Marcus is the best. Their multi-cavity dies last forever, and the unit cost is unbeatable." —
Jessica Wu
Sourcing Manager, Luxury Luggage Brand
