Overview

At Harkesh Rubber, our infrastructure is engineered to deliver precision, consistency, and reliability across every product we manufacture. Our fully integrated setup, in-house compounding, DESMA Injection Molding Machines, TungYu Vacuum Compression Machines, DOSS Automated Visual Inspection System, and Cryogenic Deflashing Machine gives us complete control over every stage of the production process, from raw material formulation to final finishing.

Backed by proprietary processing techniques and dedicated in-house laboratories allows us to maintain tight tolerances, eliminate variability, and uphold the highest standards of quality throughout. The result is our ability to consistently achieve Zero Defect Delivery at Scale.

In-House Compounding

In-House Rubber Compounding

Our fully integrated in-house compounding facility gives us complete control over material quality, consistency, and traceability from the raw polymer stage to the finished compound. We develop custom formulations in FFKM, FKM, EPDM, Nitrile, Silicone, Aflas, and other high-performance elastomers to meet demanding application requirements. Our Capabilities

Automated Intermix for high-efficiency compound mixing
2-Roll Mixing Mills for precision batch processing
Automated Batch Weighing System for accurate and repeatable formulations
Full-Fledged Testing Laboratory for comprehensive material validation
100% Material Traceability from raw material to finished batch
Consistent Inventory of prime-grade polymers for reliable supply

From formulation to validation, every compound is engineered, tested, and controlled under one roof ensuring consistent performance in the most demanding applications.

In-house Moulding

DESMA Injection Molding Machines

Our injection moulding facility is designed to deliver precision, consistency, and scalability for a wide range of rubber moulded components. Equipped with 8 injection moulding machines including 7 DESMA (Germany) and 1 MAPLAN systems, we are well-positioned to support both complex applications and high-volume production requirements.

Optimized for high-volume production with consistent productivity
Engineered to manufacture complex and precision rubber components
Scalable capacity to accommodate varying customer demands
Stable and repeatable manufacturing processes
Efficient production with shorter lead times
Flexible manufacturing for diverse component sizes and complexities

Our robust injection moulding infrastructure enables Harkesh Rubber to consistently deliver high-quality rubber components while meeting evolving customer requirements with speed, reliability, and precision

Maplan Injection Molding Machine

Adding further depth to our moulding capabilities alongside our DESMA machines, Maplan Injection Molding machine strengthens our ability to handle demanding, tight-tolerance applications across critical industries.

Precision-engineered for tight-tolerance, high-specification components
Supports complex mould geometries with consistent part quality
Reliable process control for demanding material formulations
Enables faster cycle times without compromising accuracy
Well-suited for critical applications in semiconductor, pharma, and aerospace sectors
Adds redundancy and flexibility to our overall moulding capacity

With the Maplan molding offers customers a broader manufacturing bas, combining volume capability with the precision needed for the most exacting component specifications.

TungYu Vacuum Compression Machines

With 10+ vacuum compression moulding stations ranging from 100 to 350 tonnes, our facility combines the reliability of Tung Yu Vacuum Compression Technology with robust manufacturing capabilities to produce high-quality rubber components for demanding applications.

Vacuum-assisted moulding for defect-free components
Suitable for large, thick, and intricate rubber parts
Reduced risk of voids and air entrapment
Flexible production for low to medium-volume requirements
Capable of processing a wide range of high-performance elastomers

Mold parts under vacuum conditions, eliminating air entrapment and reducing porosity or voids. This ensures superior part integrity, critical for high-performance sealing applications.

Inspection

DOSS Automated Visual Inspection System

Every component that leaves our facility is verified through our DOSS Automated Inspection System, combining automated dimensional and visual inspection to ensure defect-free rubber components before dispatch. By eliminating manual inspection variability, we deliver consistent quality that meets the tightest tolerances demanded by critical applications.

Defect-free parts, delivered consistently
Zero-sampling inspection, every single part checked, not just a batch
Reduced incoming QC time and cost on your end
Faster, more reliable lead times through inline inspection (no post-production rework delays)
Tight dimensional consistency across large production runs
Full traceability and documentation to support your OEM and export compliance needs

Tagarno Digital Microscope

Critical features and surface finishes are verified under high-magnification digital microscopy, giving you confidence in quality even at the finest tolerances. This level of detailed inspection catches what standard checks can miss protecting you from surface-level defects before parts ever reach your line.

Fine-tolerance verification for critical, high-precision features
Early detection of surface-level defects pitting, scratches, tool marks before dispatch
Added confidence for applications where surface finish is functionally critical (sealing surfaces, bonded interfaces)
Reduces risk of field failures tied to undetected surface imperfections

Vision Measuring System (VMS)

Non-contact, optical dimensional measurement for intricate part geometries. This ensures micron-level accuracy without physically stressing the component.

Captures dimensions using camera and light, eliminating deformation risk on soft elastomers and thin-walled parts and tolerances down to microns, critical for sealing surfaces and interference fits
Verifies complex geometries like O-ring cross-sections, diaphragm contours, and multi-lip seal profiles
Image processing algorithms to identify part boundaries precisely, removing operator-dependent variability
Inspects fine features such as flash lines, parting lines, and small-bore ID/OD on miniature components
Stores part-specific inspection programs for repeatable, high-speed measurement across production batches
Overlays measured geometry against CAD models to flag dimensional drift before parts reach the customer
Generates traceable measurement records for dimensional reports, supporting audits in regulated industries like aerospace and pharma

Finishing

Cryogenic Deflashing Machine

Excess flash is cleanly removed using ultra-low temperature deflashing, delivering precise, consistent finishes without compromising part integrity — even on complex geometries. This ensures your parts arrive dispatch-ready, without the inconsistency or damage risk that comes with manual trimming.

Clean, consistent flash removal without part deformation
Delivers flashless parts, ready for use without secondary finishing
Safe for complex geometries internal cavities, undercuts, intricate profiles standard trimming can't reach
Preserves dimensional accuracy and surface integrity of the finished part
Eliminates variability and risk associated with manual deflashing
Faster turnaround on high-volume orders, with no compromise on finish quality

Proprietary Finishing Techniques

Beyond standard deflashing and inspection, we've developed proprietary finishing processes refined over years of working with high-performance elastomers. These techniques deliver superior surface quality and consistency on critical sealing surfaces

Continuous Improvement

Staying ahead means staying in motion!

We treat our infrastructure as an evolving capability, not a fixed setup. As materials, tolerances, and customer requirements evolve, so do our machines, processes, and quality checks.
