Machining around the part
CNC milling, turning and supporting equipment are selected around geometry, workholding and tool access.
Explore manufacturing capabilitiesFrom Shenzhen, Changsha and Dongguan, SANHE supports your custom components from prototype development to repeat production.

Shenzhen Sanhe Innovation Technology Co., Ltd. provides custom manufacturing services for metal and engineering-plastic components. Our CNC scope covers milling, turning, mill-turn and Swiss-type machining, supported by prototype development, small batches and repeat production.
Our work includes complex aluminum housings, mounting components, precision structural parts and large frames. Sheet metal, moulds, tooling and surface finishing extend the scope around the assembly and delivery requirements of each project.
From the drawing revision to the finished part, we bring process planning, inspection and packaging requirements into the same project conversation.

Explore manufacturing capabilities
Connect datums, critical features and surface requirements to measurement methods and project records.
Explore quality & inspectionWe support components for industrial automation, machinery, medical equipment, financial equipment, smart-home products and rail transport. Share the application and acceptance requirements so the manufacturing scope can be reviewed around the part.
For overseas projects, we coordinate drawing revisions, first-piece feedback, finishing, inspection records, part identification and protective packaging. Delivery arrangements and trade terms are agreed with the order, with Lewis Liu as the project contact.
Read our FAQsKeep drawings, manufacturing decisions and inspection requirements aligned as your project develops.

Send drawings or samples with material, quantity and intended use. Discuss an NDA before exchanging confidential files.
Review critical features, workholding, finishes and inspection methods, with the quotation scope and drawing revision.
Agree first-piece requirements and approval points, then organise the batch around the confirmed specification.
Coordinate identification, surface protection, packaging and documents. Check revisions again for repeat orders.
