Protective & Instrument Cases manufacturers in China
Hard-shell protective cases are the most specified and most mis-specified product in this index. A working case is a system: an injection-moulded ABS or PP shell, a compression gasket, latches that hold under vibration, a hinge that does not creep, an optional pressure-equalisation valve, and a foam liner cut to the payload. Buyers who quote only "IP67 case, 400x300 mm" get non-comparable offers, because the differences hide in the gasket design, the wall thickness and who cuts the foam.

The specification that matters
A working case is a system: an injection-moulded ABS or PP shell, a compression gasket, latches that hold under vibration, a hinge that does not creep, an optional pressure-equalisation valve, and a foam liner cut to the payload
Put these on the drawing
- Shell material and wall thickness (ABS vs PP; virgin vs regrind content)
- Gasket type: moulded-in-place, injected foam (FIPFG) or pressed strip, and its compression set
- Latch and hinge material, and whether they are metal-reinforced
- Pressure-equalisation valve fitted or not, and its membrane type
- Liner construction: layered pluck foam, CNC-cut EVA/EPE, or PU bonded
- Test basis for any IP, drop or vibration claim, with the standard and report number
- Colour, texture and marking method (in-mould, pad print, label)
Ask this before you compare prices
Ask which of those items the factory makes in house. A plant that moulds its own shells but buys gaskets and latches from a named sub-supplier is normal and workable; a plant that cannot name them is reselling someone else’s case.
FAQ
Are all "waterproof" cases IP-rated?
No. On most B2B listings "waterproof" describes a gasketed lid, not a tested ingress rating. Ask for the test report against IEC 60529 with the sample serial and date, or treat the claim as a design intent.
What actually fails in the field?
The gasket and the latch, not the shell. Compression set in a cheap strip gasket, or a plastic latch that creeps open under vibration, accounts for most returned "failed" cases.
Can a case be certified later?
You can test a production sample at your own cost with an accredited lab. Certification of the design is separate and rarely needed for B2B shipments; what buyers usually want is a test report on the delivered lot.
