Each sample is manufactured under controlled conditions, rigorously tested for mechanical and chemical performance, and supplied for your evaluation to ensure it meets your exact requirements.

Formulation Preparation

Base polymer, pigments, and additives are precisely mixed according to your approved formulation.

Lab-Scale Mixing & Curing

Samples are produced in controlled batches using the same curing system as full-scale production.

Prototype Processing

Material is tested in molding or extrusion conditions to evaluate flow, curing behavior, and real-use performance.

Testing & Validation

Each batch is tested for hardness, tensile strength, elongation, color consistency, and processing behavior.

Technical Report

Results and recommendations are documented in a concise report to support customer review and decision-making.

Sample Delivery

Validated samples are packaged and shipped for your evaluation and feedback before production and pricing.

After you evaluate the sample, feedback is reviewed with our technical team. If performance meets expectations, we proceed to pricing and full-scale production.

Pricing, Scale-Up, and Production

After your sample is approved, we provide a detailed quotation and scale the formulation for production. Every batch follows the same controlled process and quality standards, ensuring consistent performance from pilot quantities to full-scale industrial production.

Quotation & Costing

Cost per kilogram or ton is calculated based on formulation complexity, additives, and batch size.

Order Confirmation

Final specifications, formulation code, batch size, and delivery terms are confirmed before production begins.

Scale-Up & Production

Approved samples are scaled for industrial production using the same mixing, curing, and handling parameters.

Quality Control

Every production batch is validated against the reference sample for mechanical and visual consistency.

Certifications & Compliance

Production follows ISO and industry-standard requirements, ensuring traceability and regulatory compliance.

Packaging & Delivery

Materials are packed per order size—bulk drums, 20 kg, 1 kg, or 500 g containers, ready for dispatch.

Once your production order is confirmed, our team coordinates logistics and delivery timelines. Each batch includes traceable documentation and quality verification reports.

FAQ

To prepare a formulation, we need your target hardness (Shore A), color, curing system (peroxide or platinum), processing method (extrusion, molding, or coating), and any special property requirements such as flame retardancy, conductivity, or oil resistance. If available, application details and expected working conditions (temperature, medium exposure) help us fine-tune the compound.

Yes. We offer medical and healthcare-grade silicone compounds formulated with FDA-compliant raw materials and produced under controlled manufacturing and quality assurance systems suitable for medical product development and regulatory testing.

Typical sample development takes 7–14 working days after receiving complete formulation details and technical confirmation. Complex formulations or new pigment matching may require additional validation time.

For production batches, the standard MOQ is 20 kg, depending on compound type and pigment load. Smaller pilot or sample quantities are available for testing and validation before bulk production.
