From drawing review to finished automotive aluminum parts.
Conglin can plan the route before quotation so your profile, machining and surface requirements stay aligned.
Questions to prepare before you send the drawing.
What should you send for an automotive aluminum profile quote?
Send your section drawing, alloy, temper, tolerance, machining scope, surface finish, quantity, packing method and delivery target. If you are unsure, send the drawing first and Conglin can help you identify the missing RFQ details.
Can one RFQ include battery case, motor housing and body frame profiles?
Yes. You can send several related drawings together. Conglin can separate the review by profile family while keeping one coordinated RFQ route.
Which alloys can you ask Conglin to review?
6061, 6063, 6082 and 7075 are common starting points. The final recommendation depends on your strength, machining, welding, surface and assembly requirements.
Can Conglin handle machining after extrusion?
Yes. CNC milling, drilling, tapping, cutting, punching, bending, welding and surface finishing can be reviewed with the extrusion route.
Can you get support for exterior automotive surface requirements?
Yes. Send appearance, corrosion, surface and assembly requirements together with the drawing so the finish can be planned before quotation.
Ready to review your automotive profile drawing?
Send the drawing, alloy, temper, tolerance, machining scope, surface finish, quantity, packing method and project schedule. Conglin will review the practical production route before quotation.
See how your drawing moves from profile review to finished aluminum parts
Use Conglin’s production route to confirm extrusion feasibility, machining scope, surface finish, inspection points and export packing before you send a formal RFQ. You can review the full production capability if your project needs alloy casting, mold making, extrusion, CNC, bending, welding or assembly support.
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.

Recognized systems for supplier approval
When you compare suppliers, certificates help confirm whether a factory can support controlled production, documented welding, inspection and shipment paperwork. Conglin prepares these documents so your RFQ review is faster and more transparent.
