Parts we make

Part families, not a catalogue

These are the shapes we quote most often. Every one is made to a customer drawing — the notes below describe what usually decides whether the part passes, which is also what we ask about before quoting.

CNC machined parts

Housings, brackets, heat sinks and plates milled from solid or from profile.

CNC machined heat sinks

Thin fins, deep slots and a large flat base — the combination that makes heat sinks the most deformation-prone part in milling.

Materials
6061-T6, 6063, 1050/1070, C1100 copper
Typical use
Power devices, LED drivers, motor controllers, cavity covers that also act as the heat path.

CNC machined brackets

Simple shape, difficult job: hole positions on several faces and one consistent datum for every set-up.

Materials
6061-T6, 5052, SUS304, SPCC
Typical use
Internal mounting plates, sensor mounts, motor and module adapters, optical bench supports.

Flashlight housings

A cylindrical shell where the coaxial relationship between knurled body, thread section and assembly shoulder matters most.

Materials
6061-T6, 7075, brass H59
Typical use
Handheld lighting, portable instruments, cylindrical housings with O-ring sealing.

CNC machined enclosures

A visible part: besides dimensions, surface texture, edge condition and the gap at the joint line decide whether it passes.

Materials
6061-T6, 5052, ABS/POM
Typical use
Consumer electronics and instrument housings, handheld devices, panels and decorative covers.

Camera base plates

A thin-walled turned part where the concentricity of the inner shoulder and the mounting face sets the optical alignment.

Materials
6061-T6, SUS303, brass
Typical use
Camera and lens module bases, optical interface rings, imaging module mounts.

Precision components

Couplings, stems, optical baffles and small housings with tight fit requirements.

Precision couplings

A torque-carrying rotating part: the coaxiality of the two bores matters more than the outside diameter.

Materials
6061-T6, SUS303/304, 45# steel
Typical use
Servo-to-ballscrew connections, encoder drives, automation power shafts, test benches.

Connecting stems

A slender rod where straightness and the coaxiality of both threaded ends are the two things that decide fit.

Materials
SUS303/304, 4140, 6061
Typical use
Linkages, fixture pull rods, adjustment screws, sensor extension rods, cylinder fittings.

Aluminium profile parts

Second-operation work from extrusion or plate, where datum choice and the anodising dimension chain are the risk points.

Materials
6063, 6061, 6082
Typical use
Frame beams, mounting rails, heat-spreader plates, panels and brackets, module end caps.

Earphone housings

Small, thin and curved: cosmetic consistency and the assembly shoulder are where parts usually fail.

Materials
6061-T6, brass, titanium, PC
Typical use
In-ear and over-ear cavities, acoustic module housings, portable audio shells.

Optical light baffles

An optical part: internal matt finish, sharp edges and stray-light control matter more than the outer profile.

Materials
SUS304, 6061, black anodised aluminium
Typical use
Camera and lens modules, optical inspection equipment, sensor windows, laser and imaging systems.

Turned components

Motor housings, flanges, connectors and long rods turned and milled in one set-up.

Connector components

A ring-shaped turned part with slots: bore fit and slot indexing are more critical than the outside diameter.

Materials
6061-T6, brass H62, SUS303
Typical use
Cable and hose connectors, sensor mounting rings, rotation locating rings, locking rings.

Motor housings

A thin-walled cylinder where bore coaxiality and face squareness determine how the rotor fits.

Materials
6061-T6, 45# steel, pure iron
Typical use
Servo and stepper motor shells, gearbox end caps, pump bodies, encoder housings.

Long connecting rods

A slender tubular rod: straightness, bore alignment at both ends and end threads are the three control points.

Materials
SUS304, 6061, 4140
Typical use
Equipment tie rods, adjustment linkages, sensor support rods, fixture connectors.

Precision flanges

A disc-shaped connector: bolt-hole indexing and the flatness of the sealing face are what the drawing really asks for.

Materials
SUS304, 6061-T6, 45# steel
Typical use
Pipe connections, motor and gearbox interfaces, vacuum chamber flanges, docking plates.

Pen barrels and grips

A long, thin cosmetic part: surface consistency, concentricity and weight distribution decide the feel.

Materials
SUS303, brass, 6061, titanium
Typical use
Metal pens and tool pens, instrument grips, stylus housings, precision sleeves.

CNC lathe service

Turning capacity offered as a service, including second operations and finishing.
