Below are the questions B2B buyers ask most often before sourcing custom rubber and silicone parts. They are also published as structured FAQ data so answer engines (Google AI Overviews, Bing Copilot, ChatGPT, Perplexity) can cite them directly. For procurement specifics, see our low-volume MOQ guide and the AS568 size chart.
MOQ depends on process and tooling. Prototype and bridge tooling support runs from a few hundred pieces; full production molds typically start in the low thousands. We offer low-volume paths—including LSR shared-cavity runs and small-batch compression—to keep MOQ realistic for R&D and pilot production.
FKM (Viton®), FFKM, NBR (Buna-N), EPDM, silicone (VMQ), fluorosilicone (FVMQ), HNBR, and neoprene, plus custom blends. See the material specification library for temperature, hardness, and chemical-resistance data.
ISO 9001 quality management; material and dimensional compliance to ISO 3302-1, ISO 3601, AS568, and SAE aerospace specifications (e.g., AMS 7276 for FKM). Food- and medical-contact grades are available to FDA and USP Class VI; oil & gas compounds can meet NACE MR0175 / API 6A as required.
Rapid prototype tooling is usually 3–7 days after drawing approval, with first-article samples in 1–2 weeks including molding and basic inspection. Bridge and pilot production run 2–4 weeks depending on compound and secondary operations.
Yes. We can reverse-engineer dimensions from a physical sample, confirm critical measurements, and produce a first article for verification before full tooling. A drawing is preferred but not mandatory.
Standard molded-rubber tolerances follow ISO 3302-1 Class 1 (tight) or Class 2 (general), selected per feature and part size. Critical sealing dimensions are called out on the drawing and verified by first-article inspection.
Yes. Our liquid silicone rubber parts line uses automated LSR injection for high-consistency, flash-free silicone components in medical, food, and electronics applications.
Match the compound to service temperature, media (oil, fuel, steam, ozone, chemicals), pressure, and any regulatory requirement (FDA, USP, N ACE/API). The material library and our FKM temperature guide give starting points; we provide design-for-manufacture feedback on request.
Yes. We perform rubber-to-metal and rubber-to-plastic bonding (including insert molding) for diaphragms, isolators, and sealed assemblies using qualified bonding agents and pull-test validation.
Compression molding presses a pre-form into a heated cavity—low tooling cost, best for low volumes. Transfer pushes compound through a gate—better for complex parts. Injection (including LSR) fills the cavity automatically—highest consistency and best for high volume and tight tolerance.
Yes. We mold silicone and fluorosilicone to FDA and USP Class VI requirements, with material certification and lot traceability for food-contact, medical-device, and pharmaceutical applications.
Molded parts are deflashed by cryogenic, tumbling, or manual methods depending on geometry, then inspected. Secondary operations—trimming, drilling, bonding, printing—are available inline.
A drawing or sample, service environment (temperature, media, pressure), target material or performance requirement, estimated annual volume, first-batch quantity, and any certifications. Send these via the contact form for a rapid quote.
Yes. We ship worldwide, including direct to the United States, with appropriate documentation and Incoterms agreed per order.
