Specification basis
Standard items are linked to complete part numbers and required configurations. Custom parts are linked to drawing numbers, revisions and technical requirements. Critical requirements are associated with the relevant order lines.
Quality management
Quality requirements tied to every line item.
Within ZOFANG’s integrated transmission-component supply, standard parts, customer-specified brands and custom parts keep their distinct acceptance criteria. Specifications, drawing revisions, inspection scope, accompanying documents and issue handling are linked to the project item list.
Quality starts with an agreed purchasing basis
Acceptance scope
Inspection points, sampling or full-inspection scope, acceptance criteria and record formats are agreed for each project, reflecting the requirements of the individual products.
Document requirements
Material, treatment and inspection records are defined and checked for availability as part of the order. Available documentation varies by product, brand and supply source.
Custom-part quality follows the approved drawing
Critical features
Assembly references, mating dimensions, threads and geometric requirements are reviewed in relation to the application. Ambiguous or conflicting drawing requirements are resolved before work begins.
Materials and treatments
Material grades, heat treatment and surface treatment follow the agreed requirements. Supporting records or specialized verification are defined during quotation and order review.
Samples and production batches
Where sample approval is part of the project, sample validation is distinguished from batch acceptance. Subsequent supply follows the confirmed drawing and order requirements.
Linked records
Dimensional or inspection records agreed for the project are linked to the drawing, revision and delivery batch. A drawing change triggers review of the affected requirements.
Complete identification for specified brands
Full designation checks
Brand, model suffixes and grade or configuration markings are matched to the order. Labels, packaging and accompanying documents are reviewed to the agreed project requirements.
Separate approval for alternatives
A change of brand, model or configuration is identified and approved before proceeding. Similar appearance or part-number wording does not establish technical compatibility.
Documentation and traceability scope
Supply records and accompanying documents follow the particular source and project agreement. Additional origin, material or inspection records are limited to the scope confirmed as available before ordering.
Issue handling informs future supply
Identify the issue
The order, item, quantity and batch establish the reference. Photographs, measurements and operating information help distinguish the nature of the issue.
Agree a response
Rechecking, rework, replacement supply or returns are considered as appropriate to the circumstances. Scope, responsibilities and timing are agreed between the parties.
Record the outcome
Confirmed issues and their resolution inform subsequent supply requirements. Drawings, acceptance points or packaging requirements are updated where needed.
Review repeat orders
Repeat purchases refer to the agreed technical basis, with a check for changes to revisions, brand configurations and acceptance requirements before the next order proceeds.
Clear specifications support consistent supply.
Quality requirements follow the project list, from a single branded component to a coordinated package of standard and custom parts.
