Equipment & Production Lines
Capacity is less about machine count than about whether the steps connect. We keep extrusion, skiving, CNC machining and finishing under direct control, which cuts the back-and-forth of subcontracting: third-party jobs cannot push our schedule around, and a quality issue can be traced straight to the step that caused it.
One connected process chain
- Extrusion: profiles run on new dies to the section drawing or on existing dies, cooled inline, straightened and cut to length.
- Skiving: fins are shaved directly out of the aluminum base, one piece with no interface resistance.
- CNC machining: 3-axis and 4-axis milling and turning, with fixture design, first-article trial cuts and tolerance stack-up review.
- Drilling and tapping: multi-hole production runs with dedicated tooling for consistent hole spacing.
- Finishing: anodizing, sandblasting, brushing and chromate conversion, colour matched to coupon and sample.
- Inspection and packing: first-article checks, outgoing sampling and packing designed per part type.
Key processes and where they apply
| Process | Typical use | Confirm up front |
|---|---|---|
| Profile extrusion | Machine frames, rails, heat sink bodies, structural profiles | Section drawing, alloy and temper, cut length |
| Skiving | Dense-fin heat sinks, high-power module base plates | Base thickness, fin height and pitch, heat load and airflow |
| CNC milling | Housings, end plates, flanges, parts with holes and steps | 3D model or 2D drawing, critical tolerances, datums |
| CNC turning | Shafts, sleeves, connectors, rotational parts | Concentricity and roundness, thread specification |
| Surface finishing | Cosmetic parts, areas needing corrosion or electrical isolation | Coating thickness, colour and appearance standard |
| Assembly and packing | Structural and hardware parts supplied as kits | Assembly relationship, packing and marking |
How we schedule
Order mix and lead time constantly pull against each other. Our rule is to run long lengths and small parts on separate lines, keep cosmetic parts and structural parts on separate handling routes, and schedule the parts of one project in assembly order so nothing is missing when the line builds. Rush orders get a bottleneck review before we answer — we do not say yes first and work it out later.
Capacity, stated honestly
Capacity moves with order mix and scheduling, so we do not publish a fixed daily output and we do not present an optimistic peak as the normal rate. Each project gets a schedule review against the drawing, quantity and finishing requirements.
Subcontracting and where it stops
When a special process is needed — a specific coating, heat treatment or third-party testing — we say so and quote the step and its lead time. We do not dress a subcontractor up as in-house capability. Critical steps stay with us; what we can control, we keep.
