Clear answers for manufacturing enquiries and project planning.

Yes. Projects can be reviewed for prototypes, engineering samples, bridge quantities, low-volume production, and repeat orders. The suitable route depends on geometry, material, quantity, finish, and validation requirements.

Yes. A project can combine machining, molding, sheet metal fabrication, casting, finishing, inspection, simple assembly, and packaging when the requirements are defined and each process is technically suitable.

Questions are tied to the drawing, model, revision, and requirement being reviewed. Clear written confirmation is preferred for material, finish, tolerance, cosmetic, inspection, assembly, and delivery decisions.

Provide the 3D model, a controlled 2D drawing, material grade, quantity, finish, critical dimensions, threads, surface roughness, inspection needs, and intended delivery requirement.

Common aluminum and stainless grades, brass, copper, tool steel, and engineering plastics such as POM, nylon, and PEEK can be reviewed. Final suitability depends on the drawing and application.

Yes. Finishing, masking, thread protection, inserts, and simple assembly can be included in the manufacturing plan when they are identified before quotation and production release.

Yes. A molding review can cover wall transitions, draft, ribs, bosses, undercuts, gates, ejection, parting lines, cosmetic zones, material behavior, and assembly interfaces before tooling decisions are finalized.

Trial stages are used to evaluate filling, dimensions, appearance, ejection, assembly, and process stability. The exact stage naming and approval plan should be agreed for the project rather than assumed.

Yes. The review should include insert or substrate material, retention geometry, adhesion expectations, shutoffs, flash limits, sealing surfaces, loading orientation, and any pull or functional test requirements.

Typical projects may include laser cutting, punching, bending, welding, riveting, PEM hardware insertion, brushing, powder coating, painting, marking, and simple assembly, subject to drawing review.

They influence formability, cracking risk, flat-pattern development, corner condition, and dimensional repeatability. The selected material, thickness, grain direction, and tooling all affect the result.

Identify the hardware standard, installation side, stand-off or thread requirement, weld location, weld appearance, distortion-sensitive areas, and any surfaces that must remain clear for assembly or grounding.

Kewei can compare manufacturing implications and common material characteristics, but the customer should approve the final grade against strength, temperature, chemical, regulatory, electrical, optical, and end-use requirements.

A substitution should never be assumed. Any alternative grade must be reviewed and approved against the drawing, functional requirements, documentation needs, finish compatibility, and supply condition.

Documentation support can be reviewed during quotation. State the required document type, grade, specification, traceability scope, and whether the requirement applies to every shipment or only selected orders.

Start with the base material and required function: corrosion protection, wear, conductivity, appearance, texture, color, cleanability, or marking. Then define cosmetic zones, masking, and measurable acceptance criteria.

Many coatings and plating processes add thickness, while preparation processes can remove or texture material. Fits, threads, sealing faces, electrical contacts, and tight dimensions should be reviewed with finish buildup and masking in mind.

Reference samples or controlled color information can support review, but material, texture, process batch, geometry, and lighting influence appearance. The acceptance method should be agreed before production.

Inspection documentation support is available when requested and agreed during quotation. The drawing should identify critical characteristics, sampling expectations, report format, and any required material or finish records.

Critical dimensions should come from function, fit, sealing, alignment, safety, assembly, and process risk. Mark them clearly on the controlled drawing instead of relying on an informal message or blanket tight tolerance.

Depending on the feature, support may include calipers, micrometers, height gauges, pin or thread gauges, optical measurement, CMM inspection, and appearance review. The method must suit the tolerance and geometry.

Lead time depends on process, material, quantity, tooling or setup, finishing, inspection, packaging, and delivery requirements. Timing is reviewed with the quotation and order rather than presented as a fixed universal promise.

International shipment can be discussed for the project. Provide the destination, preferred delivery terms, consignee details, packaging needs, and any documentation requirements for review.

Tracking or shipment reference information can be shared after dispatch when it is available from the selected carrier or logistics arrangement.

No. Upload your drawings and receive an engineer-reviewed quotation. This allows geometry, material, quantity, finish, inspection, packaging, and delivery requirements to be considered together.

Send CAD data and drawings where available, material, quantity, surface finish, tolerance priorities, project description, inspection needs, delivery destination, and requested timing.

A revision can change material volume, machining time, tooling, setups, mold complexity, finishing, inspection, assembly, or risk. The revised file and revision level should be reviewed before price and timing are reconfirmed.

STEP, STP, STL, IGES, IGS, X_T, SLDPRT, PDF, JPG, PNG, ZIP, and RAR files can be submitted. Native or less common CAD formats can be confirmed during review.

The 3D model defines geometry, while the 2D drawing is the preferred place for tolerances, datums, threads, surface roughness, finishes, notes, and inspection requirements. Supplying both reduces ambiguity.

Reverse-engineering support can be reviewed from a physical sample, but function, material, hidden geometry, allowable changes, and acceptance criteria still require confirmation. A sample alone may not define design intent.

Yes. NDA arrangements can be discussed before detailed project files are reviewed. Send the proposed agreement and the legal entity information required for review.

If an NDA is required, complete that process before sending confidential drawings, models, commercial information, or customer-specific project details.

No. Customer names, logos, drawings, results, and commercial details should not be published without verified records and explicit publication permission.

Packaging can be planned around visible surfaces, sharp edges, coating sensitivity, part-to-part contact, moisture, and transport risk. Identify any surfaces that require individual protection.

Labeling, bagging, separation, and revision or batch identification can be reviewed when the required format and traceability scope are specified before shipment.

Yes, subject to review. Provide the packaging drawing, label format, material restriction, quantity per pack, protection requirement, and shipping method with the RFQ.
