Optimizing Performance in Continuous Glass Production

Glass manufacturing environments demand mechanical components that perform reliably under extreme thermal stress, abrasive glass contact, non-stop 24/7 operation, and zero tolerance for dimensional variation. Even small inconsistencies in IS machine mechanisms can impact container forming, gob weight control, and overall plant throughput.

At InStock International, we provide precision-engineered solutions and high-tolerance components specifically tailored for the rigorous demands of IS machines, container glass, and hollowware production. We bridge the gap between extreme operating temperatures and mechanical longevity through advanced metallurgy, precision machining, and 55+ years of glass industry manufacturing experience.

Our glass industry supply capability is backed by Mahalaxmi Engineering Works — founded in 1967, now in its 3rd generation — the No. 1 Asian manufacturer of glass shear blades, serving 120+ plants across India and 15+ countries globally.

What We Support

We provide precision-engineered components and manufacturing expertise to ensure durability and high-speed efficiency across both hot-end and cold-end processes.

IS Machine Forming & Handling Spares

Complete range of IS machine variable equipment for center distances 3" to 6¼" — Neck Ring Arms, Baffle Arms, Blow Head Arms, Funnel Arms, Blank and Blow Mould Holders, and Take-out Tong Heads. All O-rings and seals sourced from OEM manufacturers.

Precision Shear Blades

Forged and heat-treated HSS M2 steel shear blades designed for exceptional edge retention and consistent gob weight control during high-speed cutting cycles. Manufactured by Mahalaxmi Engineering Works (Est. 1967) — Single Gob, Double Gob, Triple Gob, and Quadro Gob available in V and U profiles.

Hot-End & Cold-End Components

Engineered parts built to maintain dimensional integrity under the intense heat of the forming section and the high-speed sorting of the cold end — including mechanisms, repair kits, and complete assemblies for IS machines 85mm through 6¼".

OEM-Equivalent Replacements

Have a HEYE International, Emhart Glass, Bottero, or BDF Industries part number? We source from OEM or develop an equivalent. We are your one-stop sourcing desk in India for all IS machine spare parts — from any manufacturer, any center distance.

Reverse Engineering & Localization

Technical replication of critical imported spares to reduce lead times and support supply chain localization within India.

Where We Add Value

We leverage deep industry expertise and process-driven manufacturing to deliver reliable solutions for the world’s most demanding glass plants

Thermal Expertise

A deep understanding of how materials behave under extreme glass plant operating temperatures — selecting HSS M2 steel, heat-resistant alloys, and OEM-grade sealing materials to prevent thermal fatigue and premature failure.

Metallurgical Precision

Focused selection of high-grade tool steels and specialised alloys — heat treated to precise HRC hardness levels for maximum abrasion resistance and blade longevity in fast-cycling IS machines.

Repeatability & Durability

Advanced CNC machining and grinding ensure every batch of spares is dimensionally identical — critical for IS machine synchronisation and consistent gob weight across all sections.

Export-Ready Standards

Rigorous quality inspection, surface verification, and individual blade marking before every shipment — aligned with international industrial expectations across Europe, Asia, and the Americas.
