Your Trusted Partner for Product Innovation and Development
TryCooler is a custom manufacturing facility that integrates in-house mold development with injection molding production. With 20+ years of manufacturing experience, we have supported 800+ LSR parts customized molding projects for OEM brands, engineers, and procurement managers. Our capabilities include LSR injection molding, multi-color LSR molding,LSR insertmolding, and LSR overmolding, helping you develop silicone rubber parts with consistent quality, uniform appearance, and reliable functionality.
Why Choose TryCooler for Custom LSR Parts?
Our LSR injection molding process produces precise, flexible, and fully functional silicone rubber parts through consistent material mixing, mold temperature control, flash inspection, and batch testing. This helps you mitigate project risks from the early review stage through to stable production.
With our in-house mold manufacturing and injection molding capabilities, we are able to better control mold quality, T1 samples, mold adjustments, and production schedules.
Before mold making, we review the material, Shore hardness, parting line, flash risk, demolding, sealing areas, and assembly requirements to reduce later mold revisions.
We support custom silicone rubber overmolding and Insert Molding for precision silicone rubber parts, soft sealing parts, overmolded components, and functional assemblies.
Before delivery, we check dimensions, hardness, appearance, flash, sealing surfaces, assembly fit, and packaging protection.
We support T1 sample confirmation, mold adjustment, trial production, and stable batch production for custom LSR parts.
Before shipment, we check packaging protection and support different packaging methods based on your delivery and assembly needs.
Quality Control Built Into Every Step for Functional LSR Parts
Quality inspection is not just a final step before shipment. For custom LSR parts, we begin with First Article Inspection before mass production, verifying each part against your drawings, samples, and SIP standards. During production, our QC team performs inspections every 2 hours and monitors key dimensions, appearance, functionality, injection parameters, mold temperature, and curing stability. If a quality abnormality appears, defective parts are isolated within 5 minutes, root cause analysis is completed within 30 minutes, and corrective actions are verified within 8 hours. This closed-loop control helps keep your LSR parts stable, consistent, and ready for assembly or final use.
Trusted by OEM Customers for Custom LSR Parts
A reliable LSR part starts long before production. From material selection to mold making, molding control, and final inspection, our team pays attention to the details that affect your product’s performance, safety, and long-term stability.
Supported by ISO 9001:2015 and IATF 16949:2016 quality systems, we review each project based on its real application, including food contact, medical use, transparency, heat resistance, RoHS, REACH, or FDA-related requirements. Our goal is simple: help you receive custom LSR parts that fit your product, your market, and your quality expectations.
Custom LSR Parts Built Around Your Application
We can manufacture custom LSR parts based on your drawings or samples, and assist you in customizing the color, dimensions, structure, and surface finish of your products according to their specific applications. Whether your parts are intended for waterproof sealing, insulation, cushioning, skin contact, food contact, or soft silicone overmolding of plastic or metal inserts, we can adjust the design and production specifications to meet your project requirements.
Common Applications of Custom LSR Parts
The liquid silicone rubber (LSR) injection molding process produces LSR parts with excellent performance, making them an ideal choice for many industries. Common applications of liquid silicone rubber injection molding include:
Commonly used in breathing masks, silicone pads for ventilators, catheter seals, dental silicone accessories, and sealing components for in vitro diagnostic devices.
Commonly used in IP67/IP68 waterproof automotive components, radar sensor encapsulation, waterproof seals for headlight lenses, and shock-absorbing silicone parts.
Silicone rubber seals, silicone rubber plugs, buttons, and protective caps for waterproof and dustproof electronic plastic products.
Durable silicone rubber components for sealing, cushioning, insulation, vibration reduction, equipment protection, and long-term assembly use.
Soft-touch, skin-contact soft-hard co-molded parts for wearable devices, including waterproof seals, buttons, covers, and small molded components.
Weather-resistant silicone rubber parts for outdoor products, lighting assemblies, waterproof plugs, seals, and protective covers.
Customer Feedback from Custom LSR Parts Projects
Every custom LSR parts project starts with clear communication.
From Drawing to Custom LSR Parts in 4 Steps
Start your custom LSR parts project with drawings, samples, photos, or application requirements. We help review the material, hardness, mold feasibility, production process, inspection, and packaging needs before moving into production.
Please provide your STEP/STP files, physical samples, 2D drawings, product photos, quantity, material requirements, and application details so we can provide an accurate quote for custom silicone parts.
Before tooling begins, we review the part’s geometry, material grade, hardness, moldability, sealing areas, and assembly requirements. By addressing these issues early on, we can help you minimize unnecessary mold modifications, reduce development costs, and ensure a smoother transition from prototype approval to mass production.
For new custom LSR parts projects, you can verify the design through 3D printing, CNC prototype, T1 mold samples, or small-batch trial production before moving into mass injection molding.
Once the samples have been approved, we will move your project into mass production and assist with packaging, labeling, and export delivery.
What Our Clients Say？
“TryCooler helped us review the sealing edge and flash risk before tooling. The T1 samples were easier to approve because the critical areas were checked clearly.”
MichaelMechanical Engineer, Electronics Device Project“We needed a clean, food-contact silicone gasket with stable hardness and color. Their team confirmed the material and packaging details before production, which helped us avoid rework.”
AnnaSourcing Manager, Kitchen Appliance Project“The overmolded silicone parts required good bonding and a clean edge around the plastic insert. TryCooler reviewed the insert positioning and overflow risk before mold making.”
DavidProduct Manager, Handheld Device Project
If you’re unsure whether LSR, TPE, TPU, EPDM, or other elastomers are suitable for your application, please let us know your application details, hardness requirements, operating environment, and functional specifications. We can help you evaluate the best material options before processing.
We prefer 3D CAD files such as STEP or STP, together with 2D drawings, material requirements, hardness, quantity, and application details. If you only have samples or photos, we can also review them first.
We can support food-grade and medical-grade LSR material selection based on your application requirements. Material documents can be discussed before production.
MOQ depends on part size, material, mold structure, and production requirements. Small-batch trial production can be discussed before mass production.
Yes. An NDA or NNN agreement can be signed before drawing or sample review.
