Drawing-first engineering review

Send the profile geometry before you decide the machining and welding route

CNC features, welding sequence, material temper, extrusion tolerance and packing method can change the quotation. Conglin reviews your drawing as a complete production route, not only a material list.

For CNC machined profilesShare 2D/3D drawings, hole pattern, slot position, end machining, flatness, straightness and tolerance requirement.
For welded profile assembliesShare weld length, joint type, reference standard, assembly fixture needs, surface finish and inspection points.
For transport structuresTell us the vehicle, railway, container or marine application so we can review load, corrosion environment and packing route.
For supplier approvalAsk for certificates, lab proof, welding documents, inspection records and packing photos together with your RFQ.

RFQ information checklist

Give your team a faster way to get a workable quote

The more complete your starting information is, the faster Conglin can confirm feasibility, cost drivers, lead time and document support.

Profile drawingCross-section, alloy, temper, wall thickness, cut length, tolerance and expected annual or project quantity.
CNC scopeHole size, slot width, milling surface, chamfer, end machining, datum, tolerance and inspection method.
Welding scopeJoint position, weld length, assembly size, fixture reference, cosmetic requirement and standard requirement if applicable.
Surface and packingAnodizing, coating, brushing, protection film, packing method, label requirement and export destination.
Approval documentsMaterial certificate, dimensional report, welding proof, lab certificate, photos, project qualification and factory capability documents.

Project case directions

Use real application context to improve your machining and welding quote

Share the end use with your drawing so Conglin can check whether CNC features, welded joints, alloy choice and inspection documents match the application.

Railway aluminum assemblies

Railway aluminum assemblies

Send profile drawings, welding standard, drilling pattern and approval documents so Conglin can reOpen solution → and proof needs before quotation.

Cargo box and van body structures

Cargo box and van body structures

For logistics bodies, share section drawing, cut length, connection detail, surface requirement and packing method for export review.

Marine welded aluminum structures

Marine welded aluminum structures

For workboats and marine equipment, tell us alloy, plate/profile combination, welding route, inspection requirement and corrosion environment.

Automotive lightweight frame parts

Automotive lightweight frame parts

For body frame profiles and machined components, confirm tolerance, CNC feature location, joining method, fixture needs and batch quantity.

Manufacturing facilities reference

Connect CNC, welding and aluminum profile production in one review

Conglin manufacturing facilities support extrusion, mold development, machining, welding, assembly and inspection. Use the facility reference when your team needs proof of production control.

Certification & Quality Systems

Use Conglin quality proof for supplier approval

Your team can review lab proof, certificates and project qualification evidence together before moving from drawing review to production.

Certification

Quality proof before your order

Conglin supports international procurement teams with quality-system certificates, welding qualifications, inspection records and export-ready documents. The goal is simple: help your engineering, purchasing and compliance teams reduce supplier risk before production starts.
