Diverse Materials Tailored to Your CNC Requirements
DEK has machined metals and plastics in its own Shenzhen factory since 2002. Stock is bought with mill certificates and every grade is cut on in-house 3-, 4- and 5-axis machining centers, CNC lathes, EDM and grinding equipment, never sent to a supplier network.
Choose a material family below to see the grades we machine, their properties and typical parts. If a grade is not listed, send the drawing: an engineer will confirm machinability, stock availability and lead time with the quote.

Engineering Support from Start to Finish
Our engineering team works alongside your designers from day one, identifying potential manufacturing issues before they become production problems.
-
Material & Spec Consultation
Guidance on material selection, heat treatment specifications, and surface finish requirements based on real-world machining experience.
-
DFM Review Before Machining
Engineers check wall thickness, tool access, tolerances and material choice on your drawing and send DFM notes with the quote, before any metal is cut.
-
Inspection & Documentation
In-process and final inspection on CMM, with inspection reports, FAI reports and material certifications supplied on request.
From Material Choice to Finished Part
The same engineer-led workflow applies to every material, from a single prototype to a production batch.
