Compound Development
Developing compounds around performance, environment, durability and application requirements.
End-to-end rubber engineering · Chakan, Pune
When rubber becomes an engineering problem, we solve it.
From compound development and mould engineering to injection moulding, bonding, testing and production — Polyelastica brings the complete development chain together.
ENGINEERINGMaterial × Geometry × Process
Not just a rubber parts manufacturer.An engineering partner for difficult rubber components.
01 / Capabilities
One partner across the rubber value chain.
We connect material, tooling, moulding and validation so the component is engineered for both performance and manufacturability.
Tool & Mould Engineering
DFM-led decisions across part geometry, rubber flow, venting, tooling and repeatability.
Rubber Injection Moulding
Controlled injection moulding from prototype development to repeatable production.
Rubber-to-Metal Bonding
Feasibility, adhesive selection and process development for bonded components.
Testing & Validation
In-house testing to understand material behaviour, process capability and product performance.
NPD & Scale-Up
From feasibility and prototyping through pilot lots, validation and regular production.
02 / What we solve
Material. Geometry. Process. Performance.
The difficult rubber components are rarely difficult for only one reason. Our engineering work sits at the intersection of material behaviour, tooling, flow, bonding and validation.
Automotive & EVBellows, seals, hoses, heat-shielding and application-specific components.
IndustrialEngineered rubber parts where durability, consistency and manufacturability matter.
Material developmentCompounds designed around temperature, mechanical, chemical and fire requirements.
Custom developmentNew components and difficult manufacturing problems that need engineering attention.
03 / From enquiry to production
A structured path from idea to repeatable production.
We progressively reduce technical and manufacturing risk instead of jumping straight from drawing to production.
01→
Enquiry
Application, drawing, volumes and initial requirements.
02→
Quick Estimate
A preliminary costing to establish commercial fit.
03→
Feasibility & DFM
Manufacturability, material, flow, tooling and process risks.
04→
Prototype
Initial tooling/process development and sample parts.
05→
Pilot Lots
Production-like validation of quality and repeatability.
06
Regular Production
Controlled, repeatable manufacturing and improvement.
04 / Engineering in practice
Problems we have helped solve.
Real development work shows how we approach difficult rubber applications.
0.95 mm-wall control-link bellows
A demanding bellows application required thin-wall consistency, controlled demoulding, air evacuation and long-lasting flashless performance.

A demanding thermal-safety application combined high-temperature resistance, rubber-to-aluminium bonding, fire performance and intricate geometry.
Discuss a similar challenge →Multi-size components in one mould
A tooling approach was developed to consolidate multiple part variants where separate tooling was not commercially attractive.

A new manufacturing facility is taking shape.
Our new 20,000 sq. ft. facility in Askhed, Chakan is currently under construction and is expected to be completed in approximately 7–8 months.
The expansion is intended to create greater room for manufacturing, engineering, testing, automation and future growth — building the capability for the problems we want to solve next.

07 / Knowledge centre
Engineering knowledge should be shared.
Practical insights on rubber materials, injection moulding, mould design, process optimization, variation and failure analysis — built to help engineers and buyers make better decisions.
08 / The Polyelastica approach
Engineering depth over corporate scale.
We invest in capable equipment, safety, standardization and technical learning. The goal is simple: solve the problem properly, then make the solution repeatable.
Safety firstNever traded away for upfront cost.
RepeatabilityStandardize and automate where it improves quality.
Continuous improvementExperiment, learn and turn improvements into standards.
