INSPECTION & TESTING
Inspection for Custom Silicone Components
Inspection points should follow the characteristics that matter to the actual component. SM can review custom silicone and related interface parts against the current drawing, approved physical references, mating conditions and project-specific acceptance requirements.
Share the quality information already available so the relevant checks, review stages and documentation expectations can be discussed with the project.
Start with the drawing, sample and quality information already available.

INSPECTION OBJECTS
Define the Characteristics That Control Acceptance
A useful inspection plan starts by identifying which features affect appearance, fit, assembly or the intended product behavior.
01
Drawing Requirements
Identify the current revision, critical notes and features that control the component.
02
Approved Sample
An approved sample can supplement the drawing for agreed appearance, feel, fit or other physical characteristics.
03
Appearance & Markings
Identify visible surfaces, legends, color references and other appearance-sensitive areas.
04
Critical Dimensions
Highlight dimensions that influence alignment, fit, assembly or movement.
05
Fit & Assembly
Provide the housing, mating part or representative geometry where it affects the component.
06
Tactile / Force
Define the tactile or actuation target and acceptance reference before a method is agreed.
07
Surface Durability
Identify which printed or coated area matters and what wear condition needs review.
08
Environmental Context
State the relevant exposure requirement without assuming a standard test route.
ACCEPTANCE REFERENCES
Use the Current Drawing and Approved Physical References
A check is useful only when the acceptance reference and revision are clear.
01
Current Drawing
The current released drawing provides the dimensional and technical reference for the component.
02
Approved Physical Sample
The approved sample can define agreed appearance, fit and other physical characteristics.
03
Artwork / Color Reference
Approved artwork and visual references help define legend position, color and visible appearance.
04
Mating Components
Relevant housings, frames or other mating parts provide context for fit and interface checks.
INSPECTION STAGES
Connect Inspection to the Production Stage
01
Sample Review
Compare early parts with the drawing and agreed references before a production reference is established.
02
In-Process Checks
Review defined characteristics at the stage where they can be meaningfully evaluated.
03
Final Inspection
Evaluate finished parts against the current drawing, approved sample and agreed release references.
04
Release Decision
Use the agreed acceptance conditions to support the shipment decision.
Detailed methods, frequency and sampling remain project-specific.
APPEARANCE REFERENCE
APPEARANCE CHECKS
Review the Surfaces the User Will See
Appearance checks may cover visible surface condition, markings, coating appearance, color reference, edge condition and alignment within the finished interface.
The applicable checkpoints should follow the approved artwork, sample and project requirements.
Physical references are useful where appearance cannot be fully defined by text alone.
- surface condition
- visible marks or defects
- printed or laser-processed legend position
- coating appearance
- color reference
- visible flash or edge condition where applicable
- alignment with the finished interface
DIMENSIONAL CHECKS
Focus Measurement on Critical Features
Critical dimensions are the features most likely to affect locating, alignment, openings, mating fit, assembly or functional movement.
The drawing should identify their priority.
Measurement should follow the component and agreed requirement.
Tolerance and measurement method remain component-specific.
- fit with the mating housing
- button or keypad position
- locating geometry
- openings and alignment
- assembly relationship
- functional movement where applicable

FIT & INTERFACE
Check the Component in Its Mating Context
A silicone component may meet its individual drawing and still create a problem if the surrounding interface is not considered.
Where practical, interface checks can use a mating housing, representative geometry, locating features or an approved assembly sample.
This is especially useful for keypads, molded buttons and other components whose visible spacing and movement depend on neighboring parts.
- the mating plastic housing
- representative mating geometry
- the accepted assembly sample
- defined locating features
PROJECT-SPECIFIC REVIEW
Agree the Method Before Treating a Target as a Test Result
Some projects need criteria beyond dimensional and visual inspection.
The applicable method should follow the product requirement rather than a generic test list.
Tactile / Force
Define the tactile or force target and acceptance reference before confirming the method.
Surface Wear
Define the critical surface, condition and evaluation basis before a wear check is agreed.
Temperature Context
Identify the exposure condition and the component characteristic that needs evaluation.
Project-Specific Method
Method, duration, acceptance limits, sampling and reporting should be agreed for the actual project. Buyer-defined requirements are review inputs, not blanket SM performance claims.
QUALITY BRIEF
What to Send When Quality Criteria Matter
Send the current drawing revision, approved sample where available, critical dimensions, visible requirements, mating context and any expected inspection record or documentation type.
PART REFERENCE
- current 2D drawing or 3D data
- accepted sample, if available
- critical dimensions
- appearance-critical areas
- artwork / color reference
- mating components
APPEARANCE / FUNCTION

CONNECTED QUALITY
Link Each Check to the Process That Creates the Feature
Inspection is most useful when it stays connected to the manufacturing stage that creates the feature being checked.

FAQ
Frequently Asked Questions About Silicone Component Inspection
What quality information should I send with an RFQ?
Send the current drawing revision, critical dimensions, appearance points, mating information and any customer-specific acceptance or documentation requirements.
Can an approved sample be used as a reference?
Yes. An approved sample can supplement the drawing for agreed appearance, feel, fit or other physical characteristics.
Do all components use the same inspection plan?
No. Inspection points, method, frequency and records should follow the component, manufacturing route and agreed project requirements.
Can fit be reviewed with a housing or mating part?
Where relevant and available, mating parts or representative geometry can provide the context for interface checks.
Can printed or laser-processed areas be inspected?
Visible appearance, artwork position and other agreed surface characteristics can be included where they are relevant to acceptance.
Can SM provide inspection records?
Include documentation expectations in the project brief. The available record type and format need to be confirmed for the specific project.
Does this page confirm a specific test standard?
No. If a customer standard or test method applies, provide it for technical review before quotation or sample approval.
Are inspection tolerances the same for every component?
No. Tolerances depend on the component design, manufacturing route, mating relationships and approved project specification.
