Custom Machined Plastic Parts with ±0.005mm Tolerance and Small Batch CNC

Custom Machined Plastic Parts, Small-Batch CNC Machining, and Precision Machined Components

Shenzhen Hongsinn Precision specializes in the OEM/ODM manufacturing of precision non-standard components, providing custom machining services—including custom machined plastic parts, small-batch CNC machining, and precision machined parts—to clients worldwide.

We offer CNC turning, milling, drilling, tapping, and multi-axis machining capabilities for engineering plastics, metals, and composite structural parts, working from client-provided 2D engineering drawings, 3D CAD models, or physical samples.

We develop tailored machining solutions based on part geometry, material properties, dimensional tolerances, and operating environments—covering everything from prototypes during the R&D phase to small-batch pilot runs and subsequent mass production.

Engineering plastics are characterized by their light weight, wear resistance, corrosion resistance, insulating properties, and dimensional stability, making them widely used in mechanical, electronic, and automation equipment, as well as industrial products.

Hongsinn Precision offers CNC turning and milling services for various engineering plastics based on customer drawings.

For new product R&D, market testing, and small-scale production projects, customers often do not need to purchase large quantities of parts at once.

Hongsinn Precision provides small-batch CNC machining services, allowing for production runs tailored to specific project needs, thereby helping customers reduce upfront inventory pressure and development costs.
