Share the available drawing, specification, conductor or cable dimensions, installation dimensions, quantity and application. We use those inputs to identify the relevant product route and the key points that still need confirmation.

A complete BOM is not required for the first discussion. Send a partial list, tender file, old model or site photo. We can separate confirmed items from missing dimensions, quantities, standards and application details so you know exactly what needs clarification before quotation.

Yes. SUNENG provides one-stop supply for equipment, components, accessories and custom parts. Send your product list so we can confirm specifications, quantities, inspection requirements and delivery arrangements together.

We compare the application, mechanical dimensions, electrical ratings, material, interfaces and installation conditions against the requested specification. A similar name or appearance alone does not establish equivalence; any proposed substitute should be reviewed against the project requirements and approved by the customer before ordering.

For eligible parts, development can start from parameters, installation dimensions, a drawing, an old component or a reference sample. We then review feasibility, process route, tooling, sample approval and small-batch production.

Before order confirmation, agree the critical dimensions, inspection scope, required records, packaging marks and delivery milestones. Lead time is confirmed after product scope, quantities, drawings or samples, approvals and production slots are clear. Inspection may cover materials, dimensions, appearance, assembly or applicable tests; split shipments can be planned around project priorities.
