Liquid Silicone Rubber Materials and Part Review
Review liquid silicone rubber as a candidate route for your drawing. Part geometry, material grade, tooling and inspection requirements determine the project discussion.
01 / LSR
Choose a material route for the actual component
Provide the drawing, existing silicone grade or required properties, sample quantity and expected order pattern. Review liquid silicone rubber alongside a solid-silicone route using the same functional requirements. The material form, tooling and process proposal need to be considered together; availability is confirmed for the defined project.
02 / LSR
Compare the inputs behind each proposal
Ask what material will be delivered or processed and how the proposed route supports the drawing and inspection requirements.
| Proposal | Inputs to confirm |
|---|---|
| Solid silicone rubber | Identified grade or compound, supplied form, proposed molding method, tooling and sample conditions |
| Liquid silicone rubber | Identified components or grade, handling and mixing requirements, proposed tooling and molding conditions |
| Both routes | Critical geometry, fluid exposure, finish, inspection, demand pattern and sample-approval criteria |
03 / LSR
Define small fluid-handling features precisely
For a small seal or a component around fluid channels, mark the sealing land, channel geometry, alignment features and functional dimensions. Identify each contacting fluid, concentration, temperature and cleaning sequence. Agree measurement support, handling and the assembly leak or flow criterion for the representative sample.
- Separate drawing dimensions from the assembled clearance and compression.
- Identify the surfaces and edges that affect sealing or flow.
- Agree how samples are measured, packaged and installed for evaluation.
04 / LSR
Compare material evidence and part results separately
Specify the required material properties and test preparation. For the finished component, define dimensions, appearance, flash and any post-curing requirement. Keep results linked to the grade, part state and sample lot. Color or transparency, a material report and the installed function each require their own acceptance basis.
05 / LSR
Prepare the candidate and sample decision
Send the original specification, drawing revision, quantity and the question the samples must resolve. Agree the material reference, proposed manufacturing route, evaluation and approval responsibility before recurring supply. Include any required records, packaging and change review with the enquiry.
