SURFACE DECORATION CAPABILITY
Silicone Printing, Laser Engraving & Surface Finishing
SM supports silicone printing, spray coating, laser engraving and UV printing for custom silicone components.
The finishing route is defined around the molded geometry, artwork, appearance target and final interface.
Start with a drawing, artwork file, existing sample or molded part.

PROCESS ROLE
Surface Finishing Starts With the Intended Result
A molded silicone component may still need graphics, color definition, a controlled surface appearance or interface markings before assembly.
Graphics & Legends
Buttons, keypads and control surfaces may need symbols, text or other visual identification.
Appearance & Color
Color and surface appearance should be defined against an approved visual reference where appearance is critical.
Surface Feel
Where a coating is part of the approved design, its appearance and feel need to be confirmed on the actual molded part.
Interface Integration
Artwork and finished surfaces need to remain aligned with button geometry, openings, mating housings and other interface details.
PROCESS OPTIONS
Four Surface Processes for Custom Silicone Components
Silicone Printing
Confirm: artwork, color, graphic position
Spray Coating
Confirm: coated area, masking area, appearance
Laser Engraving
Confirm: legend position, contrast, surface stack
UV Printing
Confirm: artwork detail, color, surface geometry
ARTWORK & DFM
Artwork and Part Details to Define Before Processing
Artwork needs to connect with the molded geometry and the finished assembly.
Artwork
Provide vector artwork or the clearest available source file for legends, symbols and graphics.
Color
Identify required colors or provide an approved physical reference where color matching matters.
Process Area
Mark the intended printed, coated or laser-processed area on the drawing or sample.
Surface Geometry
Curves, raised keys, recessed areas and edge conditions can affect how a surface process is applied.
Graphic Alignment to Molded Features
Critical graphics need a clear positional relationship to the molded features.
Mating Parts
If the silicone component fits into a plastic housing or another interface, provide the mating part or geometry where practical.
Backlighting Context
If the graphic interacts with backlighting, identify the lit areas and intended visual effect before the finishing route is confirmed.
Reference Sample
An approved sample can help define appearance, color and positioning when drawings alone do not capture the full visual target.
PROCESS WORKFLOW
From Molded Part to Approved Surface Finish
01
Part & Artwork Input
Provide the molded-part drawing, artwork, color information and any existing sample.
02
Surface Assessment
Identify the processing area, geometry, visible surfaces and assembly context.
03
Process Direction
Match the supported process to the required graphic or finish.
04
Artwork & Process Preparation
Prepare the artwork and production inputs required for the selected surface process.
05
Trial Processing
Apply the selected print, coating, engraving or UV process to a sample part.
06
Sample Confirmation
Check appearance, graphic position, color and other agreed visual points.
07
Production
After sample approval, continue with the confirmed processing route.
08
Final Inspection / Assembly
Inspect the finished component and continue to related assembly where required.
PRINTING
Printing and UV Printing for Silicone Components
Printing is most useful when the artwork is developed around the actual molded surface.
Silicone Printing
Printed legends, symbols and graphic areas need to align with the molded geometry and intended interface.
Artwork & Placement
Graphic size, position, color and alignment need to relate to molded features rather than a standalone artwork file.
UV Printing
UV printing provides another route for approved graphics where the surface geometry and visual requirement fit the process.
Sample Reference
The first decorated sample provides the visual reference for placement and appearance before production.
LASER PROCESSING
Laser Engraving for Defined Legends and Graphics
Laser engraving is selected when the design calls for laser-processed legends, symbols or surface graphics.
The result depends on how the molded part, surface layers and artwork work together.
Surface Stack
Identify the molded base and any surface layer that forms part of the final appearance.
Graphic Position
Laser artwork needs to align with the physical key or interface geometry.
Contrast
Confirm the visible relationship between the processed graphic and surrounding surface on the actual sample.
Backlighting Context
For a backlit design, identify which legends or areas need to interact with the light path.
Confirm the visual result on an assembled or representative sample rather than from artwork alone.
COATING
Spray Coating for Defined Surface Areas
Spray coating can be used where selected silicone surfaces require a defined coated appearance.
Surface Appearance
Specify the intended visual finish using an approved sample, drawing or other clear reference where possible.
Finish Target
Evaluate the intended appearance and feel on the molded component rather than relying on a written description alone.
Masking & Process Areas
Identify areas that must remain uncoated, visually separate or available for later assembly.
Coating Confirmation
Use the decorated sample as the production reference for appearance and defined processing areas.
SAMPLE VALIDATION
Confirm the Decorated Sample Before Production
Production inspection then follows the current drawing, approved artwork and accepted decorated sample.
Graphic Position
Confirm symbols, legends and graphics are aligned with the intended molded features.
Color & Appearance
Compare the finished surface with the approved visual reference.
Surface Condition
Check the processed area against the agreed visual standard for alignment, surface condition and visible process defects.
Fit & Assembly
Confirm that the finished part still works with its mating housing, buttons or other assembly components where relevant.

FAQ
Frequently Asked Questions About Silicone Surface Finishing
Can I send artwork separately from the part drawing?
Yes. Provide the clearest available artwork file together with the part drawing or sample so graphic position can be related to the molded geometry.
Can SM print legends or symbols on silicone buttons?
Yes. Printed legends and symbols can be considered where the artwork, surface geometry and selected printing route are compatible.
Does SM support laser engraving on silicone parts?
Yes. Laser engraving is part of SM’s supported surface-processing scope. The final result depends on the part surface, artwork, contrast and any coating or lighting context.
Can the finish be coordinated with a backlit keypad design?
Backlighting context can be included during process planning. The relevant legends, surface layers and light path should be confirmed on a representative sample.
Can I use an approved physical sample as the visual reference?
Yes. A physical sample can help define color, appearance and graphic positioning when drawings or artwork do not fully capture the intended finish.
Can the finished silicone part be checked with its mating plastic housing?
Yes. Where fit or graphic alignment depends on the surrounding assembly, provide the mating component or relevant geometry for sample confirmation.
What information matters most for printing or coating?
Part geometry, artwork, graphic location, color, intended process, processing areas and any mating or lighting context are useful starting inputs.
How is the final surface appearance approved?
The decorated sample is compared with the drawing, artwork and agreed visual references before it becomes the production reference.
