Prototype evaluation
Evaluate fit, assembly access and the visible surface. Record any drawing changes before ordering the next stage.

CNC components
From samples to repeat orders
Repeat manufacturing for housings, brackets and plates, with drawing revisions and inspection linked to each batch.
PROCESS · PARTS · PROJECT DETAILS
A clear route from prototype to repeat supply
Each stage has a different purpose: prove the design, approve the first piece, then control repeat production against the same revision.
First-piece release
Connect the approved sample to the drawing revision, material, finish and critical measurements.
Repeat batch delivery
Use a consistent part identity, inspection plan and packaging method. Agree split shipments when assembly schedules require them.
Project reference
| Prototype | Agree the sample quantity and features to validate. |
|---|---|
| Production release | Confirm the drawing revision, first-piece approval and inspection plan. |
| Repeat delivery | Agree batch quantities, required dates and packaging before scheduling. |
Machining specifications
- Part types
- Housings, brackets, plates and related components
- Material
- Aluminum alloys; grade and condition per drawing
- Dimensions & tolerances
- Released drawing revision and the agreed batch inspection frequency.
- Surface finish
- As-machined or specified finish; colour and masking per project
- Order type
- Prototype, small batch and repeat orders
- Batch quantity & delivery
- Based on quantity, process and production schedule
Batch identity and protective packing
01
Keep each batch identifiable
Connect the part number and approved revision to the delivery quantity. Agree any separate packing for revisions or delivery splits.
02
Protect the delivered condition
Select separation and support for the actual part. Keep machined interfaces and cosmetic surfaces from contacting each other.
APPLICATION REVIEW
From one component to an equipment assembly
Review housings, mounts and frames together when an assembly contains several custom components.
Include with your drawing: Internal layout, interface locations and designated cosmetic faces.
ENGINEERING GUIDE
What changes when a sample becomes a batch
A repeatable order needs an agreed revision, acceptance method and batch identity as well as a good sample.
| Structural feature | Planning consideration | Drawing / acceptance input |
|---|---|---|
| Approved first piece | Confirm agreed features before releasing the following quantity. | First-piece quantity, approval owner and release criteria. |
| Drawing revision | Keep the model, drawing and approved changes associated with the order. | Part number, revision, change description and effective batch. |
| Inspection frequency | Agree which features receive first-piece, in-process or final checks. | Critical characteristics, sampling requirements and required records. |
| Split deliveries & identification | Separate quantities and revisions so receiving can identify the delivered batch. | Delivery split, package labels, part protection and record linkage. |
MANUFACTURING ROUTE
See how the decisions connect
Select a stage to see its review input and confirmation points. The route is planned against the actual drawing.
Planning schematic · not measured geometry or a fixed cutting sequence
01 / Prototype
Confirm function before fixing the batch baseline
Use the initial samples to clarify fit, geometry, finish and open drawing questions. Record the changes that need approval.
- Review input
- Drawing/model, quantity and validation priorities.
- Decision / output
- Confirmed requirements or a clearly identified revision.
02 / First piece
Identify the features needed for release
Agree first-piece quantities, the feature list, measurement state and the party responsible for approval before later quantities proceed.
- Review input
- Released revision, first-piece scope and approval arrangement.
- Decision / output
- An agreed decision on the remaining production quantity.
03 / Batch supply
Keep revision and inspection requirements connected
Confirm inspection frequency, quantity, finishing reference and any delivery splits for the accepted manufacturing route.
- Review input
- Batch quantity, inspection scope and delivery plan.
- Decision / output
- Identifiable quantities with the agreed delivery records.
04 / Repeat order
Review what changed before repeating the order
Check the new order against its approved baseline. A changed feature, material or finish needs review before applying it to a production batch.
- Review input
- Previous revision and an explicit change description.
- Decision / output
- Confirmed revision and effective batch for the repeat order.
QUOTE & DELIVERY SCOPE
Fix the revision and delivery batches before quotation
Confirm the included operations, acceptance and supply stage so the quotation describes the part you actually need.
- Release scope
- Approved part/revision, first-piece quantity and the owner of batch-release approval.
- Repeat-order scope
- Changed features, material/finish and the batch to which a revision applies.
- Acceptance scope
- First-piece checks, agreed inspection frequency and any delivery records.
- Packing scope
- Batch quantities, separate revisions, identification and staged shipment labels.
Choose the order stage
Sample / first-piece review
- The first-piece requirements and the release baseline for later quantities.
- Agree the drawing revision, approval features and whether later quantities wait for confirmation.
Repeat / batch delivery
- Confirm the released revision and any changed material, finish or functional requirement.
- Agree quantities, inspection frequency, delivery records and any split-shipment plan.
ENGINEERING GUIDE
Questions before you send the drawing
Clarify the requirements that are easily missed in a model alone.
Is there a fixed minimum quantity?
Send the trial and anticipated repeat quantities together. The practical batch and setup cost depend on geometry, material and finishing.
Does a repeat order automatically use the old drawing?
Identify the required revision on each order. Confirm any changes rather than relying on the file name or the previous shipment.
Can quantities be delivered in stages?
Discuss release quantities and required dates before scheduling, including whether first-piece approval must precede the remaining batch.
