Are you an ISO 9001 certified manufacturer?

Yes. Anlintech is ISO 9001:2015 certified, with in-house mold design, full material traceability and final inspection reports on every batch.

What is your minimum order quantity (MOQ)?

Prototypes can start from a single cavity; production scales to multi-million-piece runs using compression, transfer and injection molding.

What are your typical lead times?

Prototypes are typically ready in 7-15 days; production tooling takes 2-4 weeks depending on part complexity and material.

Which rubber materials do you offer?

FKM (Viton), silicone (LSR and HCR), NBR, EPDM, HNBR, FFKM and customer-specific compounds engineered to the application.

Do you make custom O-ring sizes?

Yes - to AS568, ISO 3601 and JIS B2401 standards, or fully custom cross-sections and groove geometries.

Can you mold to a sample or drawing?

Yes. We reverse-engineer from a physical sample or 2D/3D drawing and verify the material before production starts.

Do you support medical and food-grade parts?

Yes. FDA, USP Class VI and platinum-cure LSR options are available for food, beverage and medical contact.

What we can make

FKM/VITON Products

FKM/VITON (Fluorocarbon Rubber) is a high-performance synthetic elastomer. It exhibits superior aging and ozone resistance, low gas permeability, and good electrical insulation, making it ideal for demanding applications in automotive (seals, gaskets), aerospace, oil & gas, and chemical processing.

Silicone Products

Silicone is a highly versatile synthetic elastomer. It offers good electrical insulation, high chemical inertness, and biocompatibility. With low compression set and stable mechanical properties, widely used in seals, medical devices, kitchenware, electronics, and automotive components.

Rubber Products

Rubber is a highly elastic polymer material. It exhibits excellent abrasion resistance, shock absorption, and electrical insulation. Widely used in seals, hoses, gaskets, grommets and industrial components, its versatility stems from customizable hardness and processability via vulcanization.

Rubber Bellows & Boots: Materials, Design & Custom Molding

A rubber bellows — often called a boot — is a deceptively simple part that does critical work: it shields a shaft, joint, or linkage from dust, moisture, and debris while flexing through thousands of movement cycles. Get the material and convolution design wrong and it cracks; get it right and it quietly protects the […]

Rubber Stoppers: Materials, Types & Custom Sizing for Lab & Industry

Rubber stoppers are among the most universal sealing components — from a chemistry lab flask to an industrial fitting. Yet “just send a stopper” often fails, because the material, hardness, and hole pattern decide whether it seals, survives the media, and meets compliance. This guide covers stopper materials, types, and how to get custom sizes […]
