Materials and Compliance Standards

Base Metals

H62 / C26800 brass for solid mechanical strength, H65 / C27000 brass for optimal bending and crimping performance.

Electrical Standards

Manufactured in accordance with AS/NZS 3112 dimensional, insulation, and temperature rise requirements.

Environmental Compliance

Fully compliant with RoHS and REACH regulations, eliminating restricted heavy metals in electrical contact components.

industry applications

Mating Tip

Precision-chamfered edges to prevent socket damage and reduce insertion force during repeated connection cycles.

Insulation Sleeve Zone

Specifically dimensioned upper shaft sections designed to securely retain partial thermoplastic insulation sleeves required by AS/NZS 3112.

Crimp / Wire Connection Zone

Engineered with barrel ears, open wire grips, or internal threads matching specific wire gauge crimping methods.

Anchor Feature

Includes barbs, knurled sections, or shoulder stops molded securely into plastic plug bodies to stop axial pull-out or twisting under strain.

Surface Finishes

Finish Type	Thickness / Spec	Primary Function
Electroplated Nickel	3.0 - 5.0 um over copper strike	Prevents surface oxidation and adds wear resistance during insertion and withdrawal.
Electroplated Tin (Bright/Matte)	3.0 - 8.0 um	Optimizes wire soldering efficiency and provides good corrosion protection.
Bare / Anti-Tarnish Passivated	Chemical protective film	Maintains raw brass conductivity for internal secondary overmolding applications.

Application Scenarios

Consumer electronics chargers and power adapters for the Australian and New Zealand markets.
Household appliance detachable and molded power supply cords.
Industrial extension cords, power distribution units, and portable electrical tools.
Commercial office equipment and IT power distribution cables.

OEM Customization Capabilities

Drawing Execution

Production built strictly from customer CAD drawings, step files, or physical master samples.

Dimensional Changes

Custom pin lengths, varying slot depths, specialized barrel crimp geometries, and exact angular tolerances.

Material Papers

Mill test certificates provided for copper alloy chemical makeup and hardness ranges (HV 120-150).

Manufacturing Capability

High-Speed Stamping

25T to 125T high-precision presses with multi-station progressive dies for high-volume flat pin and angled blade production.

Automatic Lathe Machining

CNC sliding-head lathes for round ground pins, hollow tubular pins, and threaded terminal inserts down to $\pm 0.01\text{ mm}$ tolerances.

In-Line Production

Automated deburring, ultrasonic cleaning, and barrel plating lines to maintain clean surfaces and consistent coating thickness.

Dimensional Checks

2.5D optical image projectors and digital micrometers checking pitch, width, thickness, angle accuracy, and pin straightness.
Plating Checks

X-ray fluorescence coating thickness testers measuring micro-inch levels of nickel and tin.
Mechanical Testing

Push-pull force testers checking terminal retention strength inside molded housings and insulation sleeve pull-off limits.
Traceability

Batch lot controls linking raw material mill sheets to final shipping inspection reports.

What to Specify When Ordering

Standard Reference: AS/NZS 3112 type code or custom engineering drawing number.

Dimensions: Overall length, pin thickness, diameter, width, angle configuration, and crimping section size.

Material Grade: Specified brass alloy (H62, H65) or conductivity needs.

Surface Treatment

Nickel plating, tin plating, or unplated bare brass.

Insulation Requirement

Inclusion or specification for AS/NZS compliant partial insulation sleeves.

Packaging

Bulk bagged, carrier tape-and-reel, or anti-rust paper layers.

Order Volume

Yearly forecast or per-lot quantity needs.

Q: What brass alloy materials do you use for AU standard plug pins?

A: We use H62 (C26800) and H65 (C27000) brass strips and rods, offering balanced electrical conductivity and mechanical rigidity.

Q: Do your plug pins comply with AS/NZS 3112 standards?

A: Yes. Our parts are made strictly to AS/NZS 3112 dimensional, angular, and safety rules. We supply complete material test reports and inspection sheets with every commercial order.

Q: Can you supply pins with the required partial insulation sleeves?

A: Yes. We manufacture flat active and neutral pins engineered to accept or integrate the thermoplastic partial insulation sleeves mandated by AS/NZS 3112 standards.

Q: Can you make custom AU plug pins from our engineering drawings?

A: Yes. Over 70% of our work supports custom OEM designs. We check customer CAD files (STEP, IGES, PDF) to build progressive stamping dies or CNC machining setups for your exact specs.

Q: What is the standard plating thickness for nickel or tin-plated pins?

A: Nickel plating ranges from 3.0 to 5.0 micrometers over a copper flash. Tin plating ranges from 3.0 to 8.0 micrometers. Thickness can be adjusted to meet salt spray corrosion goals.

Q: What is your typical production lead time for bulk orders?

A: Standard production for existing tools takes 15 to 20 business days. New custom tool builds and sample approvals take 25 to 30 days depending on die complexity.

Q: How do you pack plug pins to prevent rust during ocean shipping?

A: Pins are packed in moisture-blocking polybags with desiccants, sealed boxes, or vacuum carrier tapes. For bare brass items, anti-tarnish paper or film is used to stop surface discoloration in transit.

Q: What is your minimum order quantity for custom plug pins?

A: For custom stamped or machined parts needing special tooling, the minimum order starts at 10,000 to 50,000 pieces per run, depending on material setup and part size.
