TIANJAN DESIGNMECHANICAL DESIGN STUDIO
PRODUCT STRUCTURE DESIGN

Structure that survives tooling, assembly and the first drop test

We design the inside of the product as carefully as the outside: wall thickness and ribs, snap fits and screw bosses, PCB mounting and heat paths, sealing, tolerance chains and the mould or bending strategy that will actually make the part.

Process-specific design

One geometry, three very different rule sets.

INJECTION

Plastic housings

Parting lines, draft ≥ 1°, uniform wall thickness, rib-to-wall ratios, sink-mark control, inserts and slider / lifter review with the mould maker.

SHEET METAL

Chassis & cabinets

Bend allowance and K-factor, bend radius vs thickness, welded / riveted assemblies, flat patterns, grounding and IP-rated sealing.

MACHINING

CNC parts

Datum scheme, fixturing access, tolerances and surface treatments (anodising, plating, bead blast) called out on the drawing.

Integration work usually included

The parts that get forgotten until the prototype stage.

Have a PCBA or an industrial design to package?

Send the envelope constraints and we will propose a part-splitting and assembly approach.
