OUR PROCESS

From RFQ to Completion –
A Process You Can Trust

At Flexion Silicone Manufacturing, we turn your ideas into compliant, production-ready silicone parts through a proven, transparent process.

PROCESS

Transfer Molding

Transfer molding forces material into a closed mold to produce precise, repeatable silicone parts, which is ideal for cookware, medical devices, electronics, seals and consumer goods. Note this differs from compression molding because the mold is closed and the charge is transferred under pressure, producing higher dimensional tolerance and cleaner edges. Submit a RFQ, include drawings, quantities, and material specifications for a detailed proposal.

PROCESS

Silicone Rubber Coating

Silicone rubber coating is a protective elastomer layer used to improve thermal stability, flexibility and electrical insulation on parts; Silicone coatings add durable, waterproof and chemically resistant protection to your components. Request a Quote (RFQ) for coating, molding, or hybrid solutions.

PROCESS

Silicone Injection Molding

Silicone injection molding converts Liquid Silicone Rubber (LSR) into precision parts under tightly controlled temperature and pressure. - Submit a RFQ with your drawings and specifications to receive a proposal outlining tooling, lead time, and compliance options.

PROCESS

Silicone Compression Molding

Silicone compression molding turns uncured silicone rubber into finished parts by placing measured material into a metal mold cavity, compressing it under heat and pressure, then curing and cooling for demolding. Request a Quote (RFQ) to compare molding options for your application and part geometry.

PROCESS

Extrusion

Silicone rubber extrusion is a continuous manufacturing process that shapes uncured silicone into tubes, strips, gaskets and complex profiles by forcing material through a die. Submit a RFQ, include drawings, quantities, and material specifications for a detailed proposal.

what WE deliver

We translate engineering drawings into manufacturable silicone parts and validated supply plans. Flexion provides safe, ecological, and high-quality silicone manufacturing backed by U.S. customer expectations, transparent documentation, and Southeast Asian efficiency. Our engineers communicate directly with your design team to ensure rapid feedback, cost optimization, and regulatory readiness for every project.

How it works: the core production steps

Process page image2

The core steps of silicone production remain consistent across applications:

  1. Silicon Extraction: High-purity silicon is isolated from quartz sand at ~1800°C.

  2. Synthesis: Silicon reacts with methyl chloride to form methyl chlorosilanes.

  3. Distillation: Separation of chlorosilanes ensures chemical purity.

  4. Hydrolysis: Water is added to form siloxanes and disilanol.

  5. Polymerization: Long-chain polydimethylsiloxane (PDMS) polymers are formed which are the base for most silicone elastomers.

Flexion uses this polymer as the foundation for Liquid Silicone Rubber (LSR), High Consistency Rubber (HCR), and Room Temperature Vulcanized (RTV) silicones across diverse industries.

what we make and why it matters

Silicone’s advantages like heat resistance, chemical stability, durability, and biocompatibility make it indispensable for food-contact cookware, medical tubing, electronic encapsulation, and sealing applications.
Our production methods meet or exceed FDA, LFGB, and ISO requirements for global markets.

quality control and proof

Quality assurance is embedded at each process stage: raw material purity checks, controlled distillation fractions, polymerization monitoring, and final physical testing for properties and consistency. These steps are essential to meet industry standards and to ensure parts perform reliably in critical applications.

environmental and safety considerations

Flexion incorporates sustainability practices throughout production, including safe handling of byproducts, waste reduction, and material reclamation.
We align with global standards for environmental responsibility, ensuring safe silicone production that minimizes ecological impact while maintaining consistent part quality.

Compliance for buyers manufacturing

in Southeast Asia, selling to the US

For U.S.-facing programs manufactured in Thailand or Vietnam, compliance means:

  • Verified supplier documentation and lot traceability
  • FDA 21 CFR 177.2600, LFGB, and ISO 10993 test records
  • Full support for regulatory submissions and quality audits

Our Singapore HQ coordinates compliance strategy while regional plants execute production under American-led oversight, giving U.S. buyers a reliable, compliant alternative to China.

How to engage and next steps

Start by submitting an RFQ with your part drawings, technical specifications, and performance targets.
Our engineering team will propose the optimal process, tooling, and validation path for your application.
