Design considerations
Real engineering notes from the press line.
- ! Designs must avoid sharp internal corners in load paths - heat cycling causes stress concentration at sharp corners, leading to fatigue cracks.
- ! Latch spring force typically 8-15 N for hand-operated doors - specify on drawing.
- ! Blackening (vs plating) is preferred for heat applications because plating can flake at elevated temperatures.
Common applications
Frequently asked questions
Why blackening instead of plating for high-heat parts?
Zinc plating starts to discolor at 200 C and flakes above 350 C. Black oxide (Fe3O4) is stable to 600 C and provides mild corrosion resistance plus a low-reflection finish preferred for stove applications.
Do you supply the spring pins that go with the latch?
Yes - we stock spring pins (ISO 8752 / DIN 1481) in 3-10 mm diameters. Add as a kit item on your RFQ.
Can you make a prototype latch from my sketch?
Yes - send a sketch or even a sample part. We provide DFM feedback within 1-2 business days and can quote reverse-engineered tooling based on an existing part for -200.
