Custom Silicone Components for Sealing, Flexibility & Functional Performance
GPT Precision provides custom liquid silicone rubber (LSR) molding services for components manufactured to customer drawings and specifications. We supply both finished LSR parts and complete LSR molds.
Connect material properties, critical geometry, assembly fit, and operating conditions before committing to tooling.
Sourcer les composants finis selon vos plans et spécifications de matériau. Définir les quantités, caractéristiques critiques, apparence, approbation des échantillons, et exigences d'inspection pour la production initiale et répétée.
Sourcer un moule complet pour votre installation de production désignée. Fournir les exigences de la machine de réception et de l'interface de livraison des matériaux, ainsi que les essais, acceptation, remise, et besoins en documentation.
Indiquer si votre demande concerne des pièces finies, un moule complet, ou les deux. Propriété des outils, essais inclus, responsabilités de maintenance, et toute exigence de transfert doivent être enregistrées dans le périmètre convenu.
Le nom de la pièce est un point de départ. Sa fonction dans l'assemblage fini détermine les exigences en matière de matériau et de fabrication.
Molded seals and custom gaskets for mating surfaces. Review compression, groove geometry, compression set, service media, and leakage requirements.
Flexible components that deflect or respond to pressure. Define thickness, mouvement, pressure differential, repeated-use requirements, and tear-sensitive transitions.
Flexible valve elements and sealing discs. Identify opening and closing behavior, seat geometry, pressure conditions, and fluid exposure.
Covers, boots, pads, buttons, and protective interfaces. Consider retention, tactile response, surface texture, environmental exposure, and appearance.
Hardness alone does not define sealing performance, tear resistance, compression set, or durability. Specify the conditions in which the finished part will work.
| Property | Why it matters | Information to provide |
|---|---|---|
| Hardness | Flexibility, deformation, and contact response | Target Shore hardness, Tolérance, or reference sample |
| Tensile & tear properties | Stretching, thin features, and demolding | Expected strain, feature geometry, and failure concerns |
| Compression set | Behavior under sustained compression | Compression, temperature, and service duration |
| Temperature & media | Suitability in the operating environment | Temperature range, exposure time, fluids, and cleaning agents |
| Color & apparence | Visible and contact surfaces | Color, transparence, texture, and appearance limits |
Select a grade that meets the required mechanical and environmental conditions.
Identify supporting documentation and material specifications for the intended use, including relevant medical or food-contact requirements.
Review the compatible substrate, bonding method, curing conditions, and required retention performance.
Discuss optical properties, modified chemical resistance, or other specific performance requirements.
Ces catégories décrivent les possibilités de sélection des matériaux, et non une liste de grades automatiquement disponibles pour chaque projet. Fournir le fabricant et le grade exact lorsque cela est connu; sinon, décrire la performance requise.
La faible viscosité de l'écoulement et le comportement élastique créent des exigences distinctes pour l'outillage, démoulage des pièces, et acceptation des pièces finies.
Marquer les zones d'étanchéité, les éléments d'assemblage, et les faces esthétiques sur le dessin. Ces priorités guident l'examen de l'outillage et de l'inspection.
Examiner les membranes fines, lèvres flexibles, et sections plus épaisses ensemble. Remplissage, Polymérisation, deformation, and release depend on the selected material and geometry.
LSR can flow into very small gaps. Identify flash-sensitive sealing lips and interfaces, and agree acceptable edge conditions before tooling.
Elasticity permits some undercuts to release, but deep features or thin sections may stretch excessively or tear. Review draft, release direction, and surrounding geometry.
Use material- and process-specific allowances. Identifier les dimensions critiques, Repères, measurement conditions, and any required fixtures.
Consider filling and air evacuation alongside functional areas. Identify where gate marks or surface interruptions are unacceptable.
| Decision factor | LSR | TPE |
|---|---|---|
| Processing | Thermoset material cured in a heated mold | Generally melt-processed and solidified through cooling |
| Service performance | Evaluate the grade for temperature, media, and compression set | Compare the chosen TPE family under equivalent conditions |
| Reprocessing | Cured material cannot be remelted | Some grades permit melt reprocessing, subject to restrictions |
| Application evidence | Documentation must match the grade and intended use | Documentation must match the grade and intended use |
Compare candidate grades against the same operating conditions. Neither material family is universally better.
Provide drawings, part function, material requirements, operating conditions, and quantities. Identify unresolved design decisions.
Review the grade, cavity arrangement, manufacturing approach, and approval requirements. For complete molds, include receiving-equipment compatibility.
Check dimensions, apparence, material requirements, and agreed functional performance. Identify any tooling, du processus, matériau, or design changes.
Confirm the approved revision and deliverables: production parts with agreed inspection, or a complete mold with agreed trial and handover records.
LSR is typically metered and mixed as a two-component material, injected into a heated mold, and cured. Unlike conventional thermoplastic molding, it sets through curing rather than melt cooling. Tooling investment, cavity arrangement, quantités, and inspection needs should be evaluated together.
Link approval criteria to what the component must do. Dimensions alone may not establish the performance of a flexible part.
Review critical dimensions, profil, surface condition, flash, and drawing-defined features. Agree measurement methods, fixtures, and support conditions where required.
Confirm the specified grade and required supporting records. Where hardness or other properties form part of acceptance, define the test method and limits.
Project requirements may include leakage, compression recovery, mouvement, repeated actuation, assembly fit, or exposure testing. Availability, methods, limits, and reporting are agreed per order.
Specify material certificates, dimensional reports, first-article records, or batch traceability during quotation. Establish documentation scope before production.
Inspection methods and support conditions should avoid unintended deformation of flexible parts.
Prepare the initial review around your drawing, intended use, and acceptance requirements.
Hardness depends on function, géométrie, compression, and the operating environment. Provide a specified grade or Shore A value where known; sinon, describe the required behavior and include reference samples if available.
Oui. GPT Precision supplies both finished LSR components and complete LSR molds. For a mold intended for your facility, include receiving-equipment interfaces, trial requirements, acceptance criteria, and handover documentation.
Selected grades and substrates can support multi-material components. Review substrate compatibility, processing temperature, bonding or mechanical retention, géométrie, and performance for the specific project.
Requirements depend on the material manufacturer’s guidance, processing conditions, and application. Where needed, define the treatment and acceptance criteria in the specification.
Specific grades may have documentation for particular applications. Suitability must be established for the exact grade, intended use, processing conditions, and required evidence. The terms silicone, LSR, or platinum-cured alone do not establish compliance.
Custom LSR components and complete molds, with the supply scope defined around your project.
Send the 2D drawing or 3D model, Révision, dimensions critiques, and sealing or mating surfaces. Include assembly information where it clarifies function.
Specify the grade or hardness, color, operating temperature, service media, and compression or movement requirements.
Identify sample approval criteria, testing, inspection, documentation, and applicable material requirements.
State parts, un moule complet, ou les deux. Include quantities, repeat demand, milestones, and mold receiving-equipment details where applicable.
Share your drawings and project requirements to begin a manufacturing review. If the material or design is still open, identify the decisions that need further discussion.
