How to Prepare a CNC Drawing for Quotation
A drawing that quotes cleanly shows material, critical tolerances, finish and quantity up front.
CNC Machining
CNC Prototype vs Production: What Changes?
The part may look the same, but the manufacturing route, tolerance strategy and cost drivers change with volume.
Materials
Aluminum 6061 vs 7075 for Machined Parts
A practical comparison of the two most common machined aluminum alloys by strength, machinability, corrosion and cost.
Robotics & Autonomous Systems
What Matters When Machining LiDAR Housings
Sensor housings combine optical, thermal and mechanical requirements in one part — and those interact.
Thermal Management
Cold Plate Manufacturing: Key Design Considerations
Sealing, flatness, flow path and joining decide whether a cold plate performs and stays leak-free.
Brazing / Soldering / Welding
Brazing vs Soldering vs Welding
The three processes differ mainly by temperature and by whether the base metal melts — and that changes the design implications.
Brazing / Soldering / Welding
How to Select a Brazing Alloy
Base metal, joint clearance, service temperature and atmosphere decide the alloy — not price alone.
Design for Manufacturing
What Information Should Be Included in an RFQ?
A short checklist that turns a vague enquiry into a quotation a supplier can actually commit to.
