QUICK ANSWERS
Most Common Manufacturing Questions
Short answers for buyers and engineers who need to prepare a custom manufacturing project for review.
Do I need both 2D and 3D files?
A 3D model defines geometry, while a 2D drawing communicates requirements such as dimensions, tolerances, material and surface finish. Providing both usually gives a clearer basis for manufacturing review.
Can you support prototype and repeat production?
Projects can be reviewed from prototype or sample stages through repeat production, depending on the selected manufacturing process and project requirements.
Which manufacturing processes are available?
FSD supports CNC machining, die casting, metal stamping, injection molding, tooling and surface finishing for drawing-based custom component projects.
How do I choose the right manufacturing process?
Process selection mainly depends on part geometry, material, quantity and critical features. More detailed process questions are covered below.
What information is needed for a quote?
Drawings, material, estimated quantity, surface requirements, critical features and current project stage are useful starting points for quotation review.
DRAWINGS & RFQ
Drawings & RFQ Questions
A clear drawing package helps quotation review stay focused on geometry, requirements and project stage.
What files should I send for quotation?
Send available 2D drawings, 3D models, material, estimated quantity, surface requirements, critical requirements and current project stage when possible.
Can you quote from a 3D model only?
A 3D model can support initial geometry review, but a 2D drawing is preferred when tolerances, material, finishing, threads or inspection requirements need to be defined.
What should be included on a 2D drawing?
Include critical dimensions, general tolerances, material, surface finish, threads, mating interfaces and inspection requirements where needed.
How should I identify critical dimensions?
Identify dimensions affecting fit, function, mating or assembly separately from general dimensions.
Can FSD review my drawing before quotation?
Yes. Available drawings and project requirements can be reviewed before quotation to clarify manufacturing route and missing information.
MANUFACTURING PROCESS
Manufacturing Process Questions
The right process depends on part geometry, material, quantity, tooling and downstream requirements.
How do I know whether CNC machining, casting, molding or stamping is suitable?
Process selection depends on geometry, material, quantity, wall and feature requirements, tooling needs and secondary operations.
Can one project use multiple manufacturing processes?
Yes. A project may combine processes when different components or features require different manufacturing routes. Examples can include casting followed by CNC machining, stamping followed by secondary operations, or molded components combined with other manufactured parts.
When is secondary CNC machining needed after die casting?
Secondary CNC machining may be reviewed when casting alone cannot define required machined surfaces, holes, threads or critical interfaces according to drawing requirements.
Can molded or stamped parts require additional operations?
Yes. Depending on the drawing, secondary machining, tapping, finishing or other downstream operations may be reviewed after the primary manufacturing step.
MATERIALS
Material Questions
Material choice should match function, process, finishing needs and drawing requirements.
Which materials can FSD manufacture?
Projects can be reviewed in materials such as aluminum alloys, stainless steel, carbon steel and engineering plastics, depending on the selected manufacturing process and drawing requirements.
How should I choose the right material?
Material selection should consider function, strength, weight, corrosion, temperature, manufacturing process, finishing and cost considerations.
What should I review if the material changes?
Changing material can affect machining, forming, wall geometry, tooling, finishing and achievable tolerances. The design and manufacturing route should be reviewed again when the material changes.
TOLERANCES & CRITICAL FEATURES
Tolerances & Critical Feature Questions
Critical dimensions should be separated from general dimensions so review effort is applied where function requires it.
What tolerances can you achieve?
Achievable tolerance depends on the manufacturing process, material, part size, geometry and critical features. Drawing review is required before confirming a tolerance requirement.
Why do tight tolerances increase manufacturing cost?
Tighter tolerances can increase setup, machining control, process stability and inspection requirements. They should be applied where fit, function or assembly actually requires them.
Which dimensions should be considered critical?
Dimensions affecting fit, mating, alignment, sealing where applicable, motion or assembly should normally be identified separately from general dimensions.
How should mating surfaces and hole positions be communicated?
Define relevant dimensions, datums, positional relationships or interface requirements clearly on the drawing where needed.
PROTOTYPE & PRODUCTION
Prototype & Production Questions
Prototype, sample and repeat production stages should stay connected to approved requirements.
Can you make prototypes before production?
Prototype or sample manufacturing can be reviewed according to the selected process, part geometry and project requirements.
Can the manufacturing process change after prototype review?
Yes, if the sample stage shows that another route would better match geometry, quantity, tooling or production requirements. Any change should be reviewed against the drawing and project needs.
What happens after sample approval?
Approved drawings, process requirements and inspection expectations can be carried into production planning for repeat manufacturing.
Can FSD support repeat production?
Yes. Repeat production can be reviewed after requirements, samples and the manufacturing route are sufficiently defined.
Can existing parts be transferred from another supplier?
Existing drawings, samples and current production requirements can be reviewed when customers are evaluating alternate sourcing or supplier transfer.
QUALITY & INSPECTION
Quality & Inspection Questions
Inspection review should stay tied to the approved drawing, critical features and project requirements.
How are custom parts inspected?
Inspection is reviewed against the approved drawing and relevant project requirements. The inspection method depends on the feature, manufacturing process and component requirements.
Can critical dimensions be identified for inspection?
Yes. Critical dimensions and interfaces can be identified on the drawing so inspection attention can be aligned with fit, function and assembly requirements.
Can samples be inspected before repeat production?
Sample-stage inspection can be coordinated according to approved drawings and relevant project requirements before repeat production.
How should inspection and appearance requirements be communicated?
Inspection requirements and appearance-sensitive areas should be identified clearly on the drawing or project requirements where needed. This helps align manufacturing and inspection expectations around the features that matter to the project.
SURFACE FINISHING & SECONDARY OPERATIONS
Surface Finishing & Secondary Operation Questions
Finishing and downstream operations should be reviewed together with the part drawing and manufacturing route.
Can surface finishing be included?
Yes. Surface finishing can be reviewed as part of the manufacturing route when it is defined by the project requirements.
Should appearance surfaces be marked on the drawing?
Yes. Identifying appearance-sensitive areas separately from general functional surfaces helps clarify finishing and inspection expectations.
Can threads or secondary operations be added after manufacturing?
Depending on the process and drawing, secondary machining, tapping or other downstream operations may be reviewed after the primary manufacturing step.
How can coating or plating requirements affect dimensions?
Finishing layers can influence dimensional or mating requirements on certain features, so functional surfaces and masking requirements should be identified early.
PROJECT COMMUNICATION
Project Communication & Revision Questions
Clear revision control helps quotation, sample review and repeat production stay aligned.
Can drawings be revised after quotation?
Yes, but drawing changes can affect manufacturing process, tooling, price, inspection requirements and production planning. Revised files should be clearly identified before the next project step.
How are drawing revisions and engineering changes handled?
Updated drawings or requirements should be clearly identified and reviewed against the previous project version. During sample development, revision identification helps keep manufacturing and inspection aligned with the intended drawing.
What should I send if my project requirements are not final?
Send the latest available drawing or model together with the requirements that are already known. Open items can then be identified during initial review.
Can FSD review an existing sample together with drawings?
Existing samples can provide useful reference information when combined with drawings and current project requirements. Manufacturing decisions should still be based on the requirements agreed for the new project.
