1.Part Number & Identification
DMS QZK 40
2. Material
ZL101 aluminum alloy casting – lightweight yet strong, ideal for high‑cycle clamping applications.
3. Unit Weight
0.719 KG
4. Blank Condition
Supplied as aluminum casting, ready for precision machining.
5. Critical Dimensions
Perpendicularity: ±0.02 mm
Hole spacing: ±0.02 mm
These tight tolerances ensure flawless assembly and consistent performance.
6. Machining Process & Fixturing
All operations are performed on 4‑axis CNC machines in a single setup, enabling multiple faces to be machined simultaneously.
This approach drastically improves efficiency and guarantees dimensional stability.
Key advantage: any left‑half housing can be perfectly paired with any right‑half housing – a level of interchangeability that many competitors cannot achieve (mismatched pairs often degrade performance).
7. Surface Finish & Deburring
Bright, glossy appearance – standard for all housings.
Mechanical deburring** is applied throughout, delivering clean edges, uniform aesthetics, and consistent quality. (We can provide before‑after photos comparing manual vs. mechanical deburring upon request.)
8. Inspection & Quality Documentation
Every batch is accompanied by a 3D inspection report, plus measurement videos or photos for full traceability.
We design our own specialised gauges– a capability born from deep product knowledge.
As one of the earliest manufacturers of such housings in China, we possess unparalleled understanding of application, production, and real‑world usage.
9. Packaging & Protection
Housings are securely placed in custom cardboard cartons, with photos showing the arrangement.
For bulk shipments, wooden pallets are used to prevent damage and ensure safe transit.
10. Application Scenarios
Lightweight design with a high‑strength, fully enclosed aluminium housing.
Fits cylinder bore Ø40 mm – ideal for automotive welding, assembly lines, and harsh industrial environments where reliability is critical.
11. Market Positioning & Competitiveness
We engineer our housings to perform on par with global leaders – TUNKERS (one‑piece aluminium shells), SMC (lightweight aluminium bodies), Destaco (enclosed aluminium frames), and Festo (forged aluminium housings). All share the same core requirement: high‑precision machining of high‑strength aluminium.
Our products are fully compatible with TUNKERS V40/50/63/80 series, SMC CKZ/CKQ, Destaco 82M, and Festo CLR/DW platforms. We deliver the same level of precision and quality control, yet at a competitive cost – making us the preferred partner for cost‑effective domestic alternatives and customised solutions.
