CNC Machined Brass Bushing

The CNC machined brass bushing comes with smooth surfaces free of burrs. We hold tight dimensional tolerance within +0.002~±0.005mm during production. The material delivers solid wear resistance, good electrical and thermal conductivity, plus strong anti-corrosion performance.

Tuoyuan Metal brass sleeves and molded inserts are widely used across electronics, precision machinery, auto spare parts and plastic injection molding industries. We supply reliable, long-lasting threaded connection and bearing support solutions for clients all over the world.

Product Introduction

1. Knurled Brass Molding Inserts

This knurled CNC machined brass bushing features vertical outer knurls. The textured surface locks tightly with plastic substrates to stop rotation and pull-out after long-term disassembly. It is widely embedded in consumer electronics plastic shells, power chargers and small communication device housings.

2. Single Hex Step Brass Bushing

The single hex shoulder of this brass bushing acts as a positioning stop during injection molding. It avoids sinking or shifting inside thin plastic parts, ideal for miniature smart home equipment and portable medical instrument plastic casings.

3. Double Hex Through Brass Bushing

Dual hexagon ends provide dual limiting performance for this heavy-duty brass bushing. It delivers higher pull-out strength and load capacity, perfectly matching automotive interior plastic brackets and new energy storage plastic base components.

Advantages of the CNC Machined Brass Bushing

All CNC machined parts from Tuoyuan Metal maintain stable mechanical performance for long-term service. We offer complete specifications covering furniture brass knobs, hexagonal threaded inserts and multi-step brass shaft fittings. Supported by over ten years of precision processing experience, every drawing is reviewed strictly before production, so buyers can place bulk orders without worrying about inconsistent size or short service life of the brass bushings.

We provide diversified surface finishing processes for custom CNC machined parts. Available treatments include polishing, sandblasting, electroplating, wire drawing, paint spraying and laser engraving. Customers can pick matching surface crafts based on application scenarios, whether they need a bright mirror finish or matte anti-abrasion surface for the brass bushing components.

Our CNC machined brass bushing features smooth, flawless surfaces and precise standard threads. Advanced CNC turning and dedicated surface treatment equipment guarantee neat thread teeth and flat inner holes. Each brass bushing undergoes strict dimensional inspection before delivery to eliminate burrs, uneven surfaces and thread tolerance errors.

FAQ

Q1: How much torque and pull-out force can these brass bushings withstand during injection molding?

A1: The exact values rely on the exterior configuration of the bushing (such as knurling depth and groove width) and the specific plastic resin used.

Q2: Which countries do you export brass bushing to?

A2: Our CNC machined brass bushing mainly exports to North America (60%), Russia, Germany, Middle East and Southeast Asia, covering more than 20 global regions.

Q3: What surface finishes can you provide for brass bushings?

A3: Mirror polishing is the standard finish for our brass bushing. Electroplating treatment can be added if you need stronger anti-rust performance.

Q4: What materials are available for these threaded insert bushings?

A4: We primarily manufacture these components using high-quality brass for excellent machinability, corrosion resistance, and thermal conductivity. We can also produce them in stainless steel, aluminum, or carbon steel upon request.

Q5: What is the main application for the hexagonal flange/head design?

A5: The hexagonal head prevents the insert from rotating during tightening or operation, making it ideal for injection molding into plastics, press-fitting into wood, or securing within metal housing assemblies.
