Our Manufacturing Process

From raw material preparation to finished-product dispatch, Sevana Polymers follows a structured manufacturing process for molded rubber products and custom polymer components.

Production Philosophy

From Raw Material to Finished Product

Manufacturing a consistent rubber component involves more than molding the final shape. At Sevana Polymers, the rubber manufacturing process begins with raw material receipt and analysis and continues through rubber mixing, compound preparation, molding, inspection, testing and final dispatch.

The exact process and checks may vary depending on the product, material and application requirements. As an experienced rubber products manufacturer in Thrissur, we maintain practical control across each stage.

Traceable Shipment
Stage 01 Receipt & Inbound Control

01 — Raw Material Receipt & Analysis

The manufacturing process begins with the receipt of the required rubber materials and compounding ingredients.

Materials are checked and evaluated as appropriate before they enter the production stream.

The objective is to ensure that all polymers, fillers, curatives, and process oils are verified against specifications before compounding.

Key Inbound Verifications:
Batch CoAs & Certification Physical Grade Check Storage & Segregation

Stage 02 Elastomer Processing

02 — Mixing & Compounding

Rubber materials and required ingredients are processed to prepare the compound needed for the product. Skilled rubber compounding ensures uniform ingredient dispersion.

Sevana Polymers uses mixing and calendaring equipment as part of its rubber processing capabilities.

The compounding stage is important for achieving the required characteristics of the rubber compound before molding.
