Project Inputs
- + Electrical function, current path, connection method, and intended equipment
- + Drawing or mating-part dimensions with critical contact surfaces identified
- + Required copper grade, conductivity expectation, finish, and substitution limits
- + Current, temperature rise, environmental, and validation requirements supplied by the buyer
- + Prototype quantity, production forecast, packaging, and change-control expectations
Define Before Production
Control Points
- - Copper grade, material documentation, and lot identification where required
- - Critical diameters, threads, cross holes, flatness, and contact surface condition
- - Plating, masking, oxidation protection, and protected functional areas
- - Application-specific current, heat, and contact-resistance validation plan
- - Approved sample, drawing revision, inspection method, and change-control requirements
Final feasibility, material grade, tolerance, surface treatment, inspection method, MOQ, and lead time are confirmed after drawing and application review.
Decision Evidence
What Buyers Should Validate Before Approval
These are the practical evidence points that reduce sourcing risk before sample approval and recurring production.
Electrical Evidence
Define current path, contact surface, duty cycle, heat concern, and validation method before quoting.
Material Evidence
Confirm copper grade, substitution limit, conductivity expectation, and material documentation needs.
Surface Evidence
Identify contact zones, masking, plating, oxidation protection, and appearance criteria before samples.
Inspection Evidence
Control burrs, flatness, threads, critical diameters, and contact surfaces through project-specific checks.
Manufacturing Evidence
Proof to Request Before Releasing Custom Parts
Custom terminal projects need more than a product photo. Buyers should validate the drawing basis, process route, inspection points, and approval record before recurring production.
Factory and Process Media
CNC turning, copper or brass machining, insulation parts, plating preparation, assembly, and packing photos or short videos.
Inspection Records
Thread gauges, dimensional checks, appearance zones, fit checks, first-article notes, and project-specific QC sheets.
Material and Finish Proof
Material grade confirmation, plating requirement, visible and contact zones, sample approval reference, and finish acceptance criteria.
Project and Shipment Evidence
Approved sample records, revision history, packaging instruction, label scope, export packing, and repeat-order control notes.
Evidence Media
Factory, Inspection, Project, and Shipment Proof Points
Buyers should see how product claims connect to the workshop, inspection table, RFQ file, and repeat-order controls.
Electrical Evidence
Current path, contact surface, duty cycle concern, thermal load, and validation method.
Material / Machining Route
Copper grade, machined contact features, critical diameters, cross holes, and burr control.
Contact Area / Heat Path
Busbar contact area, cable lug interface, fastener stack, conductor path, and temperature-rise review.
Surface Evidence
Plating route, masking, oxidation protection, protected contact zones, and finish criteria.
Drawing and Specification Package
What Turns a Quote Into a Production Reference
RFQ quality improves when engineering, purchasing, and quality teams agree on the same drawing, inspection, and approval basis before samples move into production.
2D / 3D Definition
Drawing, STEP/IGES model, sample photo, mating part, panel layout, or dimensioned sketch used as the review basis.
Material and Finish Schedule
Metal grade, insulation material, plating route, visible zones, contact zones, color requirements, and compliance notes.
Inspection Checklist
Critical dimensions, thread fit, contact surface, insulation fit, assembly sequence, appearance standard, and packaging check.
Approval Record
Sample approval, revision reference, change-control note, packaging instruction, and repeat-order acceptance criteria.
RFQ FAQ
Questions to Resolve Before Quoting
Use these questions to prepare a clearer drawing package and reduce quotation back-and-forth.
When should a buyer choose copper instead of brass?
Choose copper when conductivity, contact area, thermal behavior, or product positioning matters more than machining cost or threaded hardware stability.
Can Axiterm review current or temperature-rise requirements?
The buyer should provide the electrical target and validation method. Axiterm can review geometry, material, finish, and inspection route against that requirement.
How should plating be specified for copper parts?
Define contact zones, appearance zones, masking, oxidation protection, and whether the finish is functional, cosmetic, or both.
What details reduce copper sample risk?
Send the drawing, mating hardware, current path, contact surfaces, burr-control requirements, finish, quantity, and validation schedule.
