Key Advantages
- Turned structures are suitable for small-diameter, multi-step, threaded, and inner-hole copper parts with stable batch assembly dimensions.
- Copper-alloy materials balance conductive contact and mechanical connection strength for terminals, contact pins, and connector sleeves.
- Nickel, tin, or copper plating can improve conductive contact, oxidation resistance, and soldering compatibility.
- Chamfering and deburring reduce jamming during insertion, crimping, and assembly.
Materials and Construction
Precision Turned Copper Parts are made from brass, red copper, or copper alloy, depending on the required conductivity, wear resistance, thread strength, and assembly fit. Common shapes include external or internal threads, stepped shafts, through holes, blind holes, knurled areas, grooves, and chamfered edges. Surface options include nickel plating, tin plating, copper plating, polishing, or anti-oxidation treatment.
Customization Options
Customization supports outer diameter, inner hole, thread, step length, chamfer, knurling position, surface plating, and packaging method based on drawings. Customers can provide CAD drawings, samples, material requirements, electroplating requirements, key dimensional tolerances, and assembly applications.
Quality Control
Precision Turned Copper Parts are inspected according to drawing dimensions, ISO 2768, and DIN/ISO machining tolerance. Inspection focuses on material condition, outer diameter, inner hole, step length, thread go/no-go, coaxial assembly position, chamfer burrs, plating appearance, and cleanliness of conductive contact surfaces.
Frequently Asked Questions
Q: What information is needed to quote Precision Turned Copper Parts?
-
A: Please provide drawings, material grade, outer diameter, inner hole, thread specification, surface treatment, key tolerance, quantity, and application description.
Q: Can samples be arranged before mass production?
-
A: Yes. Samples can be used to confirm dimensions, threads, holes, surface treatment, contact surface cleanliness, and assembly fit before mass production.
Q: What is the MOQ for Precision Turned Copper Parts?
-
A: MOQ is confirmed according to the product version, material, tooling status, packaging method, and order quantity. No fixed MOQ is added unless it is confirmed in the order documents.
Q: How is the lead time arranged?
-
A: Regular machining orders take about 15–30 days. Orders with special plating, complex structures, or large quantities usually take about 15–45 days.
Q: How is the product packed for shipment?
-
A: Small copper parts can be shipped in bags, trays, or compartment packaging, with labels identifying model, material, quantity, and surface-treatment version.
