Manufacturing Process Insight

Production utilizes our advanced Swiss-style CNC Lathes (Sliding Headstock).

One-Setup Machining

Turning, facing, threading, and knurling are completed in a single operation to guarantee varying concentricity within 0.01mm.

Precision Knurling

Unlike standard rolling, we use a cut-knurling process to create sharp, well-defined diamond patterns that provide superior grip without flaking.

Thread Protection

Automated thread checking during production ensures every part meets the Go/No-Go gauge standards before leaving the machine.

Key Features & Benefits

Material Excellence

Material Excellence

Machined from Brass C36000, offering excellent corrosion resistance and natural antimicrobial properties.

Tactile Grip

Tactile Grip

The deep diamond knurling allows for tool-free assembly and disassembly, ideal for maintenance-heavy environments.

Leak-Proof Design

Leak-Proof Design

High-precision threads (M20 standard or custom pitch) ensure a tight seal against gas or liquid leakage.

Surface Finish

Surface Finish

Parts are degreased and passivated, resulting in a bright, oxidation-resistant gold finish.

Technical FAQ

Q1 Can you customize the thread type?
Yes, we support Metric (M), NPT, BSPP, and BSPT thread standards based on your specific requirements.
Q2 What is the minimum order quantity (MOQ) for turned parts?
We are flexible. We handle low-volume prototypes (1-10 pcs) via CNC and high-volume production runs (10,000+ pcs) via automated lathes.
Q3 How do you handle raw material verification?
We provide Material Mill Test Reports (MTR) for every batch of brass used to verify chemical composition and mechanical properties.
Q4 What surface treatments can be applied to brass connectors?
We offer electro-less nickel plating, chrome plating, zinc plating, passivation, and clear lacquering to meet your aesthetic and corrosion-resistance needs.
Q5 What inspection equipment is used to guarantee precision tolerances?
Our quality control lab utilizes CMM (Coordinate Measuring Machines), optical comparators, thread plug/ring gauges, and roughness testers for 100% compliance.
