Custom Metal Parts Manufacturer Since 2001

PROJECT WORKFLOW

From drawing review to delivery—a clear custom manufacturing workflow.

Each stage connects customer inputs, engineering decisions, approval points and production outputs. This helps procurement and engineering teams understand what is required before quotation, sampling and volume production.

REQUIREMENTS TO DELIVERY

Six stages from requirements to delivery

The exact sequence varies by process, tooling needs and validation requirements. These six stages provide a practical framework for defining responsibilities and approval gates.

01

Requirements submission

Build a complete RFQ package and identify open technical questions.

Customer inputs

  • Drawing or physical sample
  • Material and applicable standard
  • Critical dimensions and tolerances
  • Quantity, annual demand and application
  • Surface finish and delivery destination

Tianluping actions

  • Review information completeness
  • Clarify missing or conflicting requirements
  • Identify critical characteristics and project assumptions

Expected outputs

  • Defined RFQ scope
  • List of technical questions
  • Information basis for engineering review
02

Engineering review

Evaluate manufacturability and select a practical production route.

Customer inputs

  • Current drawing revision
  • Functional and appearance requirements
  • Applicable standards and acceptance criteria

Tianluping actions

  • Review geometry, material, tolerances and volume
  • Evaluate process and tooling options
  • Identify secondary operations and inspection needs

Expected outputs

  • Manufacturability feedback
  • Proposed process and tooling route
  • Confirmed assumptions for quotation
03

Quotation & project plan

Define the commercial and technical scope before project approval.

Customer inputs

  • Sample and production quantities
  • Delivery location and commercial requirements
  • Required quality documents and approval process

Tianluping actions

  • Prepare quotation scope and pricing basis
  • Define tooling, sampling and production assumptions
  • Identify exclusions, options and estimated schedule

Expected outputs

  • Quotation package
  • Proposed project route
  • Clear inclusions, assumptions and approval points
04

Tooling & sampling

Create the production basis and validate samples before volume release.

Customer inputs

  • Quotation and tooling approval
  • Sample quantity and validation criteria
  • Tooling ownership and marking requirements

Tianluping actions

  • Develop or prepare the required tooling
  • Manufacture and inspect samples
  • Provide the quality records agreed for approval

Expected outputs

  • Tooling and sample batch
  • Agreed inspection evidence
  • Customer feedback and approval actions
05

Production launch

Release the approved requirements into controlled production.

Customer inputs

  • Sample approval or agreed release decision
  • Purchase order or production forecast
  • Final packaging and delivery requirements

Tianluping actions

  • Confirm the production basis and current revision
  • Schedule manufacturing and required secondary operations
  • Apply the agreed process and inspection controls

Expected outputs

  • Approved production basis
  • Production and batch status
  • Documented changes or open actions
06

Inspection & delivery

Review the agreed acceptance requirements before shipment.

Customer inputs

  • Final documentation requirements
  • Packaging, labeling and shipping instructions
  • Delivery terms and destination details

Tianluping actions

  • Complete agreed final inspection
  • Prepare required project records
  • Coordinate packaging and delivery release

Expected outputs

  • Shipment released against agreed requirements
  • Required inspection and delivery documents
  • Batch reference where specified for the project

PROJECT RESPONSIBILITIES

Clear inputs reduce quotation gaps and project delays

A complete RFQ and documented approval points help both teams evaluate feasibility, cost and production risk using the same information.

Customer prepares

  • Current drawing, 3D file or representative sample
  • Material grade and applicable standard
  • Critical dimensions, tolerances and functional requirements
  • Order quantity, annual demand and target timing
  • Surface finish, inspection records and packaging needs
  • Application, destination and delivery terms

Tianluping reviews

  • Review manufacturability and clarify missing information
  • Recommend the process, tooling and secondary operations
  • Define quotation assumptions and project approval points
  • Coordinate tooling, sampling and production release
  • Apply agreed inspection and documentation requirements
  • Communicate open actions, changes and delivery status

REVISION & CHANGE CONTROL

Drawing changes are reviewed before they enter production

A revised drawing can affect tooling, material, machining, inspection, cost and schedule. The current revision and change scope should therefore be identified, reviewed and confirmed before the updated requirement is released to production.

Review quality control →
Drawing revisionIdentify the current file and superseded version.
Tooling impactCheck whether the existing tooling or fixture must change.
Process impactReview material, manufacturing and secondary operations.
Inspection impactUpdate critical characteristics and required records.
Commercial impactReview cost and quantity assumptions where affected.
Release decisionConfirm the approved change before production use.

START WITH A COMPLETE RFQ

Ready to review a drawing or physical sample?

Share the material, dimensions, tolerances, quantity, application and delivery requirements. The team can then review the manufacturing route and open technical questions before quotation.
