Find Answers for the Stage You Are Working On

Choose the topic that matches your current purchasing or engineering task. Each section leads to the dedicated FAQ or support page for that stage rather than repeating the full answer on this Hub.

Need a project-specific answer? General FAQ guidance may not cover drawing-specific tolerances, materials, inspection requirements or purchasing conditions. Those details should be confirmed against the actual project scope.
Quotation Questions

What Should You Prepare Before Requesting a Quote?

A useful manufacturing quotation depends on having enough information to understand the part, material, quantity, tolerances and project requirements. The FAQ Hub only summarizes the two questions buyers usually need answered before moving to the detailed quotation guide.

RFQ Input

What information should I send for an accurate quotation?

Start with the current 3D CAD model and technical drawing, then define the material or grade, quantity and critical requirements. Surface finish, target lead time, delivery terms and required inspection documents should also be stated when they affect the project scope.

Pricing Factors

What usually changes the manufacturing price?

Pricing can change with material selection, process and machine requirements, geometry, tolerance level, batch quantity, secondary operations and the inspection or documentation scope. These factors should be reviewed together rather than treating unit price as an isolated number.

Orders & Project Flow

What Happens After You Approve a Quote and Place an Order?

Once the commercial and technical scope is agreed, the project moves from quotation into order review, production planning and execution. Buyers should also know where payment terms are confirmed and how revisions are handled if the project changes after release.

Order Release

What happens after the purchase order is confirmed?

The agreed order is reviewed against the approved technical and commercial scope before production release. Manufacturing and inspection then proceed according to the confirmed project requirements and applicable approval points.

Commercial Terms

When are payment and commercial terms confirmed?

Payment terms, quotation validity and other commercial conditions should be confirmed in the quotation, purchase order or proforma invoice before production proceeds. Project-specific terms take precedence over general FAQ guidance.

Engineering Changes

What if I need to change the design after ordering?

Submit the revised CAD or drawing with a clear revision ID and identify the affected requirements. The change should be reviewed for cost, lead time, tooling and inspection impact, with updated terms approved before affected work continues.

Packaging & Delivery

How Are Parts Protected, Packed and Shipped?

Packaging and shipping are related but different project requirements. Packaging defines how finished parts are protected, identified and prepared for transport, while shipping defines how the packed goods move to the destination and which delivery terms apply.

Part Protection

Packaging Requirements

Packaging should match the part geometry, surface condition, quantity and handling risk. Separation, protective materials, labeling and carton or crate requirements should be agreed when they affect appearance, traceability or safe arrival.

Packaging scope: define any special surface protection, individual separation, labeling or export-packing requirement before shipment preparation.

Delivery Planning

Shipping, Delivery & Incoterms

Shipping arrangements depend on destination, shipment size, timing and the agreed commercial terms. The selected freight method, Incoterm and required shipping information should be confirmed before dispatch rather than assumed from a general delivery estimate.

Shipping scope: freight method, delivery responsibility, destination details and applicable Incoterms should follow the confirmed order terms.

Quality & Inspection

What Quality Evidence Should Be Defined Before Production?

Inspection requirements are easier to manage when the critical features, measurement method and required records are agreed before production. Buyers should distinguish between routine inspection, first-article evidence and any additional documentation required for the specific project.

Inspection Scope

What quality and inspection records should I request?

Start with the drawing requirements and identify which features need recorded verification. Depending on the agreed project scope, evidence may include dimensional inspection results, first-article records, material documentation or other customer-defined quality documents.

CTQ Definition

When should CTQ, FAI, CMM or PPAP requirements be specified?

Define critical features and reporting expectations during RFQ or technical review rather than after production begins. FAI, CMM measurement or PPAP-related documentation should be included only where the project requires them and the applicable scope has been confirmed.

Need the quality-system and inspection-control overview?

Review how SPI structures inspection, traceability, CTQ control and nonconformance handling across manufacturing projects.

Review Quality Assurance
Need to understand available project records?

Review the dedicated quality-document resource for manufacturing inspection records and project-specific documentation requirements.

Review Quality Documents
Project scope: inspection methods and documentation requirements should follow the released drawing, agreed quality plan and confirmed customer requirements rather than being assumed to apply identically to every order.
CAD Privacy & NDA

How Are Drawings and Confidential Project Files Handled?

Manufacturing RFQs often include drawings, CAD models and other non-public project information. File handling, access requirements and any NDA arrangement should therefore be clarified before sensitive information is shared.

File Handling

How should confidential CAD files be submitted?

Share only the project information required for quotation or manufacturing review and identify any confidentiality or access requirements in advance. Drawing revisions and related project files should remain clearly identified so the correct information is used during review.

NDA Arrangement

Can an NDA be arranged before I send project files?

Yes, when an NDA is required for the project, the confidentiality arrangement should be discussed before sensitive files are submitted. Customer-specific NDA terms or document requirements can be reviewed as part of the project setup.

Need more detail about file privacy and confidentiality? Review the dedicated privacy FAQ for additional information about project-data handling, file access, confidentiality and NDA-related questions.

Project-Specific Question

Still Need an Answer for Your Project?

General FAQs cannot define drawing-specific tolerances, materials, inspection requirements, delivery terms or commercial conditions. Send the available project information so the relevant engineering or purchasing questions can be reviewed against the actual scope.
