What is your minimum order quantity for custom parts?

We support single-piece prototypes and low-volume runs through CNC machining, 3D printing and urethane casting, and scale to mass production through die casting, injection molding and stamping. Share your target quantity and our engineers will recommend the most cost-effective process.

What tolerances can Sunmy Hardware hold?

Standard CNC tolerances are ±0.01 mm, and critical features can be held down to ±0.005 mm. Dimensions are verified with CMM inspection and documented in FAI reports before shipment.

How do you protect my drawings and intellectual property?

We sign a Non-Disclosure Agreement with you by email before collecting any 3D or CAD files. You work directly with the factory, so your data is never handed off to brokers.

Which quality documents are available with shipments?

Material certificates, RoHS compliance documents, First Article Inspection (FAI) reports and CMM dimensional reports can be supplied per project.

Which manufacturing processes are done in-house?

CNC machining and stamping are performed in our own facilities. Casting and surface finishing are completed by audited partners. All final quality control, CMM inspection and FAI are executed in-house by Sunmy engineers before global shipping.

Which CAD file formats do you accept?

We accept STEP, IGES, STL, DWG/DXF and PDF 2D drawings. Physical samples can also be reverse-engineered.

Product Description

Product Overview

At Shenzhen Sunmy Hardware Co.,Ltd., we specialize in manufacturing high-precision connector components. Our Custom Gold-Plated Brass Spring Pogo Pins are engineered for reliable electrical connections on PCBs and intricate electronic devices. As experts in Precision Turned Parts, we offer fully customized solutions, adjusting material, plating thickness, force, and dimensions to meet your exact specifications. This product is designed for applications where high reliability, smooth mating, and consistent force are non-negotiable.

Process & Manufacturing Insights

Our Pogo Pins are produced using advanced Precision Turned Parts technology, often utilizing Swiss-type CNC machines for the highest concentricity and tightest tolerances. This process ensures exceptional dimensional accuracy, often achieving tolerances as tight as +/- 0.005mm. The rotational nature of turning allows for the creation of the complex, segmented body with a highly concentric and polished surface finish. This polished surface is critical for smooth spring action and optimal plating adhesion, preventing premature plating wear. We maintain a strong development capability to design tooling and program machines for any unique pin geometry you require.

Main Features & Advantages

Exceptional Precision & Surface Finish Our CNC turning capabilities and post-process polishing result in precise segmented bodies and a smooth, low-friction surface. This ensures optimal spring performance and consistent electrical contact with minimal plating wear.
Reliable High-Cycle Electrical Connection Engineered for stable force, high cycles, and low contact resistance, crucial for PCB applications, power transfer, and signal transmission. The gold plating ensures long-term corrosion resistance and excellent conductivity.
100% Full Customization is Our Strength As your solutions provider, we do not limit you to catalog parts. Every dimension, material choice (various brass grades, CuBe, music wire for internal parts), pin geometry, internal spring force, and plating thickness is customized. We turn your concepts into real products.
Rapid Prototyping & Scalability Leveraging our strong development capability, Sunmy can provide rapid prototyping to validate your design, followed by mature scale-up to high-volume production, ensuring competitive lead times and quality.

Technical FAQ

Can you accommodate extremely tight tolerances?

A: Yes. Leveraging our advanced Swiss-type precision lathes, we can maintain tolerances of critical dimensions down to +/- 0.005mm.

What material options do you provide for the internal spring?

A: While the body and plunger are typically turned from brass with gold plating, we can use music wire, stainless steel (SUS301/304), or Beryllium copper (CuBe) for the spring, depending on the required force and environment.

Can you provide customized internal force measurements?

A: Absolutely. The internal spring force (preload, working force, full compression) is a key parameter we can calibrate based on your specific application requirements.

Does Sunmy provide engineering design assistance?

A: Yes. Our development team can review your connector design to ensure manufacturability via precision turning and suggest optimizations for cost and performance.

Frequently Asked Questions

FAQ What is a Pogo Pin and how does it work?

A Pogo Pin is a spring-loaded electrical connector consisting of a plunger, barrel, and internal spring. When compressed against a contact pad, the spring maintains consistent pressure, ensuring a reliable and low-resistance electrical connection. They are widely used in PCBs, test fixtures, wearables, and charging interfaces.

FAQ Why is gold plating used on Pogo Pins?

Gold plating provides superior corrosion resistance, excellent electrical conductivity, and long-term surface stability. Applied over a nickel undercoat, it prevents oxidation and ensures consistent low contact resistance throughout the product's lifecycle — especially critical in high-cycle or high-reliability applications.

FAQ What is the minimum order quantity (MOQ) for custom Pogo Pins?

Our MOQ is flexible and depends on the complexity of the custom design. We support both small prototype runs and large-volume production orders. Please contact our team with your specifications and we will provide the most suitable production plan and pricing for your volume.

FAQ How long does it take to receive a prototype?

Typical prototype lead times range from 7 to 15 business days depending on design complexity and material availability. Our engineering team will conduct a DFM (Design for Manufacturability) review before production begins to minimize revision cycles and shorten your overall development timeline.

FAQ What file formats do you accept for custom orders?

We accept all standard engineering file formats including DWG, DXF, STEP, IGES, and PDF technical drawings. If you only have a concept sketch or dimensional requirements, our engineering team can assist in converting them into production-ready specifications.

FAQ How do you ensure quality consistency across large production runs?

We implement rigorous in-process quality control at every production stage, including dimensional inspection using CMM and optical measurement tools, plating thickness verification, and spring force testing. Each batch is traceable, and we provide inspection reports upon request to ensure every shipment meets your exact specifications.
