ER Industries is not just a manufacturer — we are your engineering partner. Our "Pin to Plane" model covers the complete product development lifecycle, from conceptual sketches to million-unit mass production.
Conceptual Engineering
We evaluate your concept for technical feasibility and suggest optimal manufacturing routes.
3D CAD / CAM Translation
Converting ideas, sketches, or reverse-engineered samples into precise industrial drawings.
Process Optimisation
Selecting forging, casting, or machining based on material, tolerance, and cost targets.
METALFORMING
Precision Forging Capabilities
Grain-refined, high-strength forged components engineered for critical automotive, defense, and industrial applications.
Close Die Forging
Near-net-shape precision forging between matched dies. Minimal flash, excellent grain flow, ideal for complex geometries requiring high strength-to-weight ratio.
Hammer Die Forging
High-impact repeatability using gravity or power hammers. Excellent for high-volume standard parts with consistent mechanical properties.
Roll Forging
Metal shaped between rotating dies for tapered profiles and long-axis components. Ideal for agricultural, automotive shaft, and connecting rod applications.
LIQUID METAL ENGINEERING
Industrial Casting Capabilities
From intricate wax-pattern investment casting to high-integrity shell mold and heavy-duty sand casting.
Investment Casting
Lost-wax process for intricate, near-net geometries with superior surface finish and zero draft angles.
Sand Casting
Versatile high-integrity casting for large structural components with sound internal microstructure.
Shell Mold Casting
Thermosetting resin-bonded sand shells yielding tight dimensional control and fine Ra 3.2µm finish.
Continuous Casting
Directly solidified continuous strands ensuring homogeneous crystalline structure free of shrinkage cavities.
PRECISION MACHINING
CNC Machining Processes
Our precision machining center delivers components from IT Grade 4 to IT Grade 8, with surface finishes from Ra 0.4 µm to Ra 3.2 µm. We machine all metals — from aluminium to Inconel 718.
METALLURGICAL FINISHING
Heat Treatment — All 8 Processes
Precise thermal transformation cycles engineered to achieve target tensile strength, toughness, and grain refinement.
Annealing
700–900°CReduces hardness, eliminates internal stresses, and significantly enhances machinability.
Normalizing
850–950°CRestores homogeneous austenite grain sizing and ensures uniform mechanical properties.
Hardening
750–1000°CAustenitizing followed by rapid quenching to form high-hardness martensitic structure.
Tempering
150–700°CSub-critical heating following hardening to achieve optimal ductility-hardness balance.
Case Hardening
900–950°CThermochemical carburizing delivering high surface HRC with an impact-resistant core.
Nitriding
500–550°CFerritic nitrogen diffusion yielding exceptional wear resistance with zero quench distortion.
Induction Hardening
LocalizedHigh-frequency induction heating targeting critical wear zones like journals and teeth.
Stress Relieving
550–680°CThermal soaking to eliminate residual machining or welding tensions without altering hardness.
