Precision CNC Machining Parts with ±0.005mm Tolerance and Customized Color for OEM/ODM Service

Shenzhen Hongsinn Precision offers custom machining services for POM, PTFE, and brass parts, supporting OEM/ODM production based on customer 2D engineering drawings, 3D CAD models, or samples.

We employ processes such as CNC milling, CNC turning, drilling, tapping, chamfering, and precision profiling, tailored to the specific mechanical properties and operating environments of each material. POM is ideal for mechanical parts requiring low friction, wear resistance, and high dimensional stability; PTFE is suitable for components demanding low friction, chemical resistance, and suitability for specialized environments; and brass offers excellent machinability and electrical conductivity.

Hongsinn Precision develops customized machining solutions based on part structure, material, dimensional precision, and order volume, supplying precision components to sectors such as industrial equipment, automation, electronics, electrical engineering, and machinery manufacturing.

POM is an engineering plastic characterized by excellent mechanical properties, wear resistance, and dimensional stability, making it ideal for mechanical parts that require low friction and precision fits.

CNC machining enables the production of complex POM parts based on customer drawings, suitable for prototyping, small-batch runs, and mass production.
