Read the guide ↗All guides are listed below. Enable JavaScript to use the filters and self-check controls.
No matching guides.
Try a broader term, change the process, or reset the filters.
Recommendations are starting points. Confirm applicability against the material, geometry and inspection requirements of your part.
START FROM THE FEATURE
A small detail.
A different manufacturing decision.
Choose a feature to see what to specify, why it matters, and which reference to read next.
CNC MACHINING / DESIGN CONSIDERATION
Give the cutter room to work.
Show internal radii and identify deep pockets or restricted access. Review the radius together with pocket depth, tool reach and the surfaces that must mate.
SHEET METAL / DESIGN CONSIDERATION
Make the grain direction explicit.
For many rolled sheet materials, a bend line perpendicular to the rolling direction reduces cracking risk compared with a parallel bend. Confirm radius against alloy, temper, thickness and tooling.
INJECTION MOLDING / DESIGN CONSIDERATION
Start with the resin and flow path.
Use gradual wall transitions and review ribs, bosses and draft together. Suitable wall thickness depends on resin, flow length, geometry and tooling; a machined-plastic limit is not a molding rule.
THREADS & ASSEMBLY / DESIGN CONSIDERATION
Define more than the nominal size.
State thread size, pitch, class and usable depth where required. Separate a threaded connection from a precision bore fit, and identify the datums and mating requirements.
TOLERANCES & INSPECTION
Specify function.
Then control the fit.
A general tolerance note and a critical feature callout do different jobs. Define the mating surfaces, datums and inspection requirements that matter to your part.
Review Prolean standards & inspection ↗
Material, geometry, size, setup and inspection method affect what is achievable. The quotation confirms the agreed requirements.
Make the critical features visible.
Use individual callouts for functional requirements. Keep the general tolerance note for the dimensions it is intended to cover.
| On the drawing | What to define |
|---|---|
| Mating features | Fit, size and location |
| Functional datums | References for inspection |
| Surface requirement | Relevant faces and roughness |
| Inspection scope | Critical checks and reports |
Ask for a review if the design needs unusually tight control.
A standard is a specification context.
Identify the applicable standard and edition on the drawing. ISO 2768-1 addresses general dimensional tolerances; it is not a universal statement of machining capability.
| Keep separate | Confirm for your order |
|---|---|
| Drawing requirement | Standard, edition, class and scope |
| Company defaults | Applicable process and quotation |
| Feature capability | Material, geometry and inspection |
Legacy general-geometrical-tolerance notes need engineering review. Do not substitute standards without checking their scope.
Make the thread requirement complete.
The example below illustrates the information to review. It is not a default specification for every part.
| Callout element | Example / internal metric thread |
|---|---|
| Size & pitch | M6 × 1 |
| Tolerance class | 6H, if required |
| Thread depth | Specify usable engagement |
| Hole condition | Blind or through; drill depth separately |
Also identify special gauging, inserts, sealing or coating requirements.
MATERIAL → PROCESS → FINISH
The material changes
the design conversation.
Specify the grade and condition, then review the geometry and surface requirements together.
BEFORE YOU SEND THE FILE / SELF-CHECK
A clearer drawing.
A better first conversation.
This checklist helps organise your questions. It does not validate a CAD model or replace an engineering review. Your answers stay on this page until you reload it.
Critical dimensions have individual callouts.
Identify functional datums, mating fits and required inspection. Do not apply the tightest tolerance to the whole part.
DRAWING REQUIREMENT
Pockets and corners allow tool access.
Review internal radii, pocket depth, tool reach and access from each setup. Flag any sharp internal corner.
DESIGN CONSIDERATION
Thin walls and slender features are identified.
Review unsupported height, material, clamping and deflection together. No single wall minimum applies to every machined part.
PART-SPECIFIC REVIEW
Threads are fully described.
Include size, pitch, class and usable depth where required. Distinguish thread depth from drill depth in blind holes.
DRAWING REQUIREMENT
Material, finish and drawing revision agree.
Specify grade and condition. Identify coating, masking and final mating dimensions. Match the model and PDF revisions.
DRAWING REQUIREMENT
The formed part is fully dimensioned.
Include bend angles, inside radii, bend directions and functional finished dimensions, not just the flat outline.
DRAWING REQUIREMENT
Bend radius is reviewed against the material.
Confirm alloy, temper, thickness and available tooling before committing to a tight radius.
PART-SPECIFIC REVIEW
Grain direction is considered.
For many rolled sheets, a bend line perpendicular to the rolling direction reduces cracking risk versus a parallel line. Confirm for the selected grade and condition.
DESIGN CONSIDERATION
Holes and slots keep clear of deformation zones.
Measure feature clearance from the bend tangent and review it with thickness, radius and tooling.
PART-SPECIFIC REVIEW
Joining and cosmetic requirements are marked.
Define inserts, weld locations, visible faces and finish. Discuss where tooling marks are acceptable.
DRAWING REQUIREMENT
Resin grade and service requirements are specified.
Identify the resin, reinforcement if any, environment and functional requirements before choosing wall dimensions.
DRAWING REQUIREMENT
Wall thickness suits the resin and flow path.
Review wall transitions, filling and shrinkage with the molder. A CNC plastic wall limit does not define an injection molding minimum.
PART-SPECIFIC REVIEW
Draft and release direction are defined.
Review depth, texture, resin and tool opening direction together. Flag faces with limited draft.
DESIGN CONSIDERATION
Ribs, bosses and transitions avoid thick sections.
Review local mass, stress, support and sink risk against the resin and cosmetic requirements.
DESIGN CONSIDERATION
Undercuts, parting lines and gates are discussed.
Identify features that may need side actions. Agree acceptable gate and ejector locations before tooling.
TOOLING REVIEW
PREPARE YOUR RFQ
The useful details.
Before the first quote.
Bring the requirements that affect manufacturing and inspection.
What should I send with my drawing?
A STEP model where available, a dimensioned PDF, quantity, material grade and condition, finish, critical tolerances and inspection requirements. Use the same revision across the files.
What if a feature does not follow the guide?
Mark the feature and explain its function. A design recommendation is a starting point; an engineer can review whether tooling, a different setup or an alternative process is appropriate.
Can I order just one part?
Single-part enquiries can be reviewed for CNC machining, sheet metal and 3D printing. Dedicated fixtures, setups or tooling may still affect price. Molded and cast parts require a separate tooling discussion.
Are my checklist answers sent automatically?
No. Download the review notes and include the relevant questions with your enquiry. Checklist answers are not sent automatically.
How should I handle confidential drawings?
Review the privacy policy and request an NDA if needed before sharing project files.
FROM DESIGN QUESTIONS TO A MANUFACTURING PLAN
Bring the drawing.
Keep the questions.
Share your geometry, quantity and critical requirements. Discuss the manufacturing route, open design questions and inspection needs.
Confidential enquiries · Optional NDA available ↗
