Custom Silicone Molding: Precision Parts That Perform
Silicone molding is not the same as rubber molding. The material behaves differently. It shrinks more. It releases harder. It requires perfectly balanced heat across every cavity. Arcadian runs dedicated silicone molding cells separate from rubber and plastic lines. Cross-contamination ruins silicone parts, so our team maintains isolated material handling systems.
We work with liquid silicone rubber (LSR) for high-volume medical components and high-consistency rubber (HCR) for larger, thicker parts. Over 1,385 projects completed across 17 industries. Each one started with the same question: what does this part touch? Skin? Fuel? Boiling water? The answer drives material selection, mold design, and post-curing cycles. This is custom silicone molding done right—no shortcuts, no material substitutions, no surprises.

Silicone Molding Processes: From Liquid to Solid
In our LSR molding, base and catalyst flow in as two streams. They only mix right before entering the heated mold cavity. The chemical reaction happens fast. Typical cycle times run 30 to 90 seconds, depending on part thickness. This process works for high-volume production where consistency matters more than tooling cost.
When extreme temperature resistance or tear strength is required, Silicone Mold Manufacturing works with high-consistency rubber. HCR comes as a gum-like solid that mills, preforms, and compression molds under high pressure. The material handles higher durometers and thicker cross-sections than LSR.
Silicone Extrusion Services generates continuous profiles—tubes, cords, and custom shapes—for gaskets and seals. Extruded silicone then passes through a hot air vulcanization tunnel. Silicone Seals & Gaskets made this way withstand repeated compression without taking a permanent set.
Arcadian runs both LSR injection presses and HCR compression molding stations. The engineering team picks the process based on how many parts per year, the shape of the part, and what performance is needed. Medical-grade silicone molding uses validated processes with full batch traceability. Food-grade and medical-grade silicone molding services come with documented cure validation plus post-cure baking to get rid of volatiles.
Why Choose Arcadian?
Arcadian brings 1,385+ completed projects and 670+ satisfied clients to every custom silicone moulding order. Our company runs dedicated LSR injection presses with automated mixing systems. No cross-contamination. No material mix-ups.
The engineering team gives clients a DFM analysis before any steel is cut. Mold flow simulations and sample parts from prototyping are part of the package, too. LSR molding projects include documented cure parameters plus post-cure cycles. High-temperature silicone parts undergo third-party testing to make sure they stay stable under heat.
Silicone Extrusion Services ships with dimensional inspection reports. Money-back assurance on development timelines. Book a 20-minute strategy call. Get a free CAD design review. That is the Arcadian difference.

Material Knowledge & Application Engineering
Liquid silicone rubber molding works best for thin-walled parts, diaphragms, and multi-cavity high-volume runs. Silicone extrusion services work well for long continuous pieces like refrigerator door gaskets or lighting seals. For industrial use, high-temperature resistant silicone parts get tested at their maximum rated temperature for 1,000 hours.
Compression set, tensile strength, and hardness are measured before and after exposure. Parts that fail never reach the client. Silicone Seals & Gaskets for automotive under-hood applications face oil and coolant exposure. Standard silicone swells. Arcadian recommends fluorosilicone for fuel contact or heat-cured VMQ for general engine bay duty. Arcadian helps clients choose the right process—not the most expensive one.
Food Grade & Medical Grade Silicone Molding Services
Food & Medical Grade Silicone Molding Services require more than just buying certified materials. The entire production environment must prevent contamination. Arcadian maintains separate storage, mixing, and molding areas for medical and food-grade work. Handling tools get dedicated sets.
Cleanroom-compatible PPE is what operators wear. For medical-grade silicone molding used in implants or drug delivery, everything follows validated processes. Every cure cycle gets written down. Every batch has retention samples kept. Documentation covers lot numbers for raw material, mold ID, and post-cure oven logs. Custom silicone molding projects receive the same traceability standards regardless of grade.
Quality Standards Across Every Production Run
- Material traceability to source lot
- Documented post-cure cycles
- Dimensional inspection reports
- Hardness verification (Shore A)
- Tensile strength sampling
- Money-back on late delivery
