About Us
An aluminum and hardware custom manufacturer in Shishan, Foshan: four product lines, seven in-house processes, eight industries served — from a drawing to repeat production.
Foshan Chuangrongyao Metal Products Co., Ltd. (CRYJT METAL) is based in Shishan, Nanhai, Foshan — a custom manufacturer built around aluminum processing, with precision hardware alongside it. Four product lines — skived aluminum heat sinks, extruded aluminum profiles, CNC-machined aluminum parts and precision hardware — run through one manufacturing and inspection system that covers extrusion, skiving, CNC milling and turning, drilling and tapping, surface finishing, assembly and packing. Domestic engineering customers and overseas OEM/ODM buyers get one route from drawing review to repeat production.
Four product lines, one manufacturing network
- Skived aluminum heat sinks: fins are shaved out of a solid aluminum base, so fin and base are one piece with no interface resistance — suited to dense fin arrays and concentrated heat loads. Base size, fin height and pitch follow the drawing.
- Extruded aluminum profiles: standard sections run on existing dies, custom sections are tooled to drawing, with cutting, drilling, tapping, bending and secondary machining in the same flow. Used for machine frames, guide rails, heat sink bodies and structural parts.
- CNC-machined aluminum parts: 3-axis and 4-axis milling and turning for housings, flanges, end plates and connectors, including fixture design, first-article trial cuts and tolerance stack-up review.
- Precision hardware: brackets, clamps, standoffs, panels and adapters, supplied as a matched kit against the assembly drawing so buyers are not stitching together several suppliers.
All four lines share one process-review and inspection flow. Send an assembly drawing and we break it into thermal, structural and connecting parts, schedule them together and deliver in the order the line assembles.
What we can take on: blank to finished surface
| Process | Scope | What we need from you |
|---|---|---|
| Extrusion | Existing dies for standard sections, new dies to drawing; straightening and cut-to-length | Section drawing, alloy, length and quantity |
| Skiving | Dense fin skiving; pitch, fin height and base thickness reviewed against the drawing | Base size, fin requirements, heat load and mounting method |
| CNC milling / turning | 3-axis and 4-axis work with fixture design and first-article trial cuts | 3D model or 2D drawing, critical tolerances, datums |
| Drilling and tapping | Multi-hole production runs with dedicated tooling | Hole pattern, thread spec, counterbore and chamfer notes |
| Surface finishing | Anodizing (clear, black and others), sandblasting, brushing, chromate conversion | Coating thickness and appearance requirements, color sample |
| Inspection | Full first-article dimensions, sampling on key items, records with the shipment | Critical dimension list and acceptance criteria |
| Assembly and packing | Kitting against the assembly drawing, packing designed per part type | Assembly drawing, packing method and marking |
Industries we serve: more than heat sinks
From thermal management for a single board to structural and connecting parts for the whole machine, our parts go into:
- Energy storage and solar: PCS, inverters, battery pack heat sink bodies and structural parts
- Industrial control and power electronics: servo drives, VFDs, IGBT module heat sinks
- LED and lighting: high bay, stage and grow light heat sinks and housings
- Telecom and RF: base station power amplifiers, RRUs, router heat sinks and shields
- Medical and instrumentation: analyzer and imaging equipment structures and thermal parts
- Automotive and rail: on-board power, EV chargers, electronics heat sinks and brackets
- Automation equipment: profile frames, rail mounts, fixtures and adapters
- Appliances and consumer electronics: high-power supplies, audio and projector structures and heat sinks
Three ways to work with us
- Sampling from drawing: send the drawing and expected volume; we review feasibility, propose a sampling route and build samples. Volume starts only after the sample is approved.
- Small-batch pilot: validates assembly, thermal behavior and finish consistency, with inspection criteria and packing fixed during the pilot.
- Repeat production: scheduled to your order rhythm with inspection records, batch traceability and packing; long-term programs can discuss buffer stock and rolling schedules.
Domestic customers reach us by phone or WeChat; overseas buyers send drawings by email or WhatsApp. Process feedback and quotation direction usually come back within 1–2 working days. Quotations are costed on drawing, alloy, finish and quantity — no loss-leader pricing to win the order.
Quality and traceability
Critical dimensions are fully checked on the first article, key items are sampled in production, and inspection records ship with the parts. Aluminum is checked against the material certificate per batch; finish and material batches stay traceable. Fin geometry and roots are checked after skiving, flatness after milling, coating thickness and appearance after anodizing — controls sit in the process, not only at the door.
Working with overseas buyers
English drawings and specifications are handled directly. Material certificates, inspection records and shipping marks are provided as the project requires; factory visits and sample shipments are supported, and shipments follow standard terms such as FOB or CIF. Technical questions are answered by the engineers who run the process, not relayed through layers of sales.
Where we draw the line
No claims we cannot back up: tolerances, capacity and lead time are confirmed against the drawing and order quantity, and certificates or test reports are provided per project rather than advertised in general terms. Saying clearly what we can do — and what we cannot — is what keeps a supply relationship working.
